A very dry spring with rain on the way

It’s been a long time since I posted. The weather has generally been extremely uneventful, plus I’ve been busier than usual with work and side projects (including the garden). Regardless, I figured it was time for an update.

The forecast

Wed & Thu: Onshore flow increases pushing in a stronger marine layer along with a very weak front. This will result in highs in the low to mid 70s. Expect plentiful AM clouds with PM sun breaks. We could see a sprinkle Wednesday morning; otherwise, these two days will remain dry.

Fri: PM showers. A cold atmosphere up above will result in the possibility of thundershowers too. Some of the downpours could be quite heavy. Highs right around 60°.

Sat: Additional showers and thundershowers with a more steady rain likely during the late afternoon and evening hours. This will produce a widespread soaking rain for areas west of the Cascades. Downpours will have potential to be heavy. Highs will struggle to reach 60°

Sun: Showers wrap up with much of the day being dry. Just keep in mind that showers could still take place during the day on Sunday. Highs into the lower 70s again.

Mon – Wed: Partly cloudy to mostly sunny skies. Highs around 80° each day. Lows will start out chilly right around 50 to 53°.

Rain totals look to range from half an inch to just over an inch of rain here in the Willamette Valley. This will bring much needed precipitation to our region!

Aside from the first week of April, we have been unusually dry this spring. The few “rainy” days we have seen the past 8 weeks have not produced more than a third of an inch on any given day. The map below shows percent of normal precipitation locations have picked up between April 18th and June 17th. Many valley locations are running at a mere 15 to 25% of average.

We are running slightly better precipitation wise than the dry and hot spring of 2021. That year brought our most intense heatwave ever with temperatures soaring above 110° throughout the Willamette Valley. That was an awful experience. Luckily, no signs of hot weather.

As far as temperature goes, May 2025 went down in the history books as only being 0.2° above normal. For all practical purposes that’s considered average. At the moment, June is running 3.5 degrees above normal, a special thanks to the hot spell last weekend. That number will fall dramatically by this time next week due to the much cooler weather moving in.

For reference, I added a chart showing total rainfall for Salem during the month of May going back to 1997.

There is no clear trend here. The only notable thing I could see was the tendency for totals to range more drastically over the past several years, but in the grand scheme of things, several years is hardly a trend.

We’ll see where we end up for rainfall in June. For now enjoy the continued dry weather, and keep in mind that Friday through Sunday will be generally wet.

The Cascades

Planning on hiking or camping up high? Well, plan on some snowfall Friday night through Saturday night. Snow levels will dip down low enough for the volcano summits/peaks to pick up several inches of snow. Timberline, the tops of the sisters, Jefferson Park, Crater Lake, and any other peaks above roughly 5500 feet could see snow this weekend. Keep this in mind. Spots along the PCT (Pacific Crest Trail) could also see snowfall impacting hikers and backpackers this weekend. By Sunday afternoon the summer sun returns and the snow up there will quickly begin melting off again.

Storms on the way

Enjoy, but don’t bee fooled by the beautiful and warm sunny weather. Thunderstorms will become quite numerous at some point later this afternoon through the evening hours. Current temps across the region show the very warm atmosphere which is a prime ingredient for storms in this type of setup.

Lots of 70s out there and temperatures are still climbing. Meanwhile, 18,000 feet above us, a “bowling ball” of cold air, strong winds, and precipitation is heading towards us from the southwest. You can see it represented fairly well on this chart below:

The satellite image from early this afternoon shows this well with Salem (where the red arrow is pointing to) is firmly in the sunny and warm sector ahead of the cold front which is moving up as indicated by the blue arrow.

The cold front sweeps northeast later this afternoon and evening sparking numerous thunderstorms and downpours along it. Some of the storms could be severe which is extremely rare for our area. Large hail, damaging wind gusts of 55mph or higher, heavy rain, and dangerous lightning are all possible with the storms. Not every location will see such strong or severe storms, but everyone will see at least a period of very gusty winds (40mph or higher, and some intense downpours as the front moves through and temperatures drop nearly 20 degrees this evening!! Truly some wild and possibly dangerous weather for some of us between now and 8pm tonight.

The main message is be prepared for conditions to go downhill quickly when these storms do fire up and make their way up the valley, and don’t let the calm weather now fool you. Power outages, ponding of water, and downed trees are expected in at least some areas later today with the stronger storms.

Rainy and at times windy weather will continue on and off through Friday before we dry back out for the weekend.

Be safe out there!

Severe thunderstorms possible

We have a rare threat for strong to severe thunderstorms for Wednesday afternoon. Thunderstorms around here are hard to predict and pinpoint, but plan on storms possibly effecting your daily plans tomorrow (Wednesday) with widespread showers/downpours by late afternoon and early evening.

All the ingredients are coming together to create a very unstable atmosphere Wednesday afternoon as a cold front pushes through what should be a fairly mild and humid environment. The biggest threats with this particular setup would be of course lightning (cloud to ground), but also very strong gusty winds (gusts could exceed 50mph with some of the storms), and large hail. I won’t make predictions for how large the hail will be, but I’ve never seen Salem get placed into the severe Hail Outlook by NOAA, so there must be something to that.

I don’t have much experience forecasting severe thunderstorms since we hardly ever get storms here, but I’m passing along what I’ve seen, and the setup does look as though it could produce intense storms with large hail. I suppose if you have the option, I would pull the car into the garage for the afternoon. Might force some of us to clean out our garages Wednesday morning making for a win win situation…. 😉 🙂

North and east of Salem stand the highest probability for storms (especially stronger storm cells), but anyone roughly from the Coast Range eastward could get hit by a thunderstorm.

Thursday will be windy with periods of rain and additional showers, and Friday looks like a soaker as well.

Saturday looks mostly dry with just a slight chance for an isolated shower, but overall a good day for outdoor activities, and Sunday looks dry until the evening when rain again returns to the picture.

Take care, and stay safe!!

Wild weather!

Time for a storm and forecast update. The rain portion of the forecast is working out very well. Salem officially picked up 0.84″ of rain Saturday. So far today we are now over an inch and counting. Here are the Sunday rainfall totals as of 4pm.

Heavy rain came down over a large swath of the central Willamette Valley earlier this afternoon driving up creek levels and causing a few isolated spots of ponding. The Luckiamute River is just one example showing the cause and effect of all that rain.

Other rivers and creeks have also shown sharp rises today. Mill Creek in Salem is currently below flood stage, but it showed a quick jump in its level today as a result of the rain. Looks like it rose almost 2 feet since 10pm last night! No major flooding is expected, and the break in the rain will help ease those creeks some.

Expect just a few scattered showers at most over the next 12 hours as we enjoy a break in the steady rain. The next batch of rain arrives around 4am early Monday morning and will last for a few hours before ending mid morning leaving us with sunbreaks and a very unstable atmosphere tomorrow afternoon.

Monday afternoon through Tuesday morning

Wild weather will be on tap during this time frame. Heavy downpours, strong gusty winds, and even thunderstorms are possible during Monday afternoon. Dynamics are in place which could lead to some strong thunderstorms -something which is pretty rare for our region. This estimated radar image for 4pm Monday afternoon shows an intense line of showers and storms rolling across the valley. These storms would bring very heavy rain, gusty winds, and of course the possibility for lightning and thunder.

The map above is not gospel truth, but it does give us a general idea of what Monday afternoon might look like by showing the potential for storms.

Additional showers and periods of rain fall during the night Monday through Tuesday morning. Tuesday afternoon should be fairly sunny with only a couple isolated showers leftover.

As far as the wind goes, I’m still expecting the strongest winds to take place Monday afternoon through early Tuesday morning. Wind gusts since Saturday have generally underperformed with most locations in the valley seeing nothing higher than 35mph, which is still breezy, but not strong enough to cause lots of problems.

The storm coming in Monday is a totally different setup. This final round of wind will be a result of a low pressure racing northeast off our coastline. The path the storm is taking is ideal for bringing strong gusty winds to the valley. I’m confident we will see widespread gusts of 40 to 50mph resulting in scattered power outages across the valley.

Tuesday afternoon kicks off a several day stretch of calm and mild weather which should last through Friday.

Stay safe out there!!

Heavy rain, wind set to move in

We had a fun couple of days with snow and ice just over a week ago, and this past week has been fairly uneventful (a nice break for me haha), but this morning it has become very clear that impactful weather is returning to our region. Lots to cover, again, so let’s dive in!!

Main message

Copious amounts of rainfall and strong gusty winds will impact the region beginning tonight and lasting through Monday evening. Expect some power outages and localized flooding. More details below.

Details

There are three big stories with the series of storms set to move in: heavy rain, strong winds, and the potential for some rare (at least in this part of the world) strong thunderstorms. More on the wind and thunder later. Below are two separate maps showing estimated rainfall totals through Tuesday morning. Very clear message is we have LOTS of rain coming our way over the next three days!!

A good guess based on all the information I have available to me would be 2.5 to 3.5 inches of rain now through Tuesday afternoon.

The rain will range in intensity over the next few days with periods of lighter rain being blown by the wind, and periods of intense heavy rain. Out of all the rain storms we have seen this winter, this is the one that has my attention the most for localized flooding and ponding on roadways. Any locations near flood prone creeks, ditches, low laying areas, or areas with poor drainage could flood with these storms.

Flood watches and warnings are also up for several coastal rivers, the Pudding River, and the Luckiamute River. Below is a forecasted river height for the Luckiamute River. It shows it rising 13 feet between now and early Monday morning!!

So that’s the rain portion of the forecast with the rain increasing as the day goes on. I’ll be honest, the term “atmospheric river” is way over used in the media; however, it’s appropriate to use it for such a time as this. This will likely be the heaviest rainstorm we have seen here in the mid Willamette Valley this entire winter season.

The wind

After reviewing all the weather models closely, I’m much more concerned about the impact wind will have with this storm than I was just a couple days ago. Right now it appears we will have gusts widespread 35 to 45mph during three separate periods of time. The first period is this afternoon and early evening with winds relaxing a little bit while we sleep. Round two will take place during the day Sunday. Round two will feature stronger gusts than what we see today.

The winds relax big time later Sunday evening through early Monday morning before round three moves in. Round three will contain the strongest winds of the entire storm. Gusts with this round could reach 50mph in some valley locations. Weather apps may be slow to pick up on this still, but Monday looks extremely stormy with additional power outages throughout the day. Peak wind gusts will occur during the daytimes hours on Monday. It will be a wild day at work no doubt! Plan on your power possibly being disrupted at some point over the next three days due to the combo of gusty winds and saturated soils.

Finally, we have rare threat for strong thunderstorms Monday. A warm front will lift through the region Monday morning. Behind the warm front, good forcing up in the atmosphere coupled with sunbreaks ahead of the cold front will create a recipe for thunderstorms that could bring very heavy rain and strong gusty winds to some locations.

Bottom line is we have a very active set of days ahead of us, and this series of storms has my attention more than any others we have seen this year.

If time allows, I would love to update you again on Sunday as I’m confident there will be new changes by then. Stay safe, be ready for power outages, and localized flooding, and enjoy the weekend!

Winter wonderland!!

Woo hoo! Snow has been widespread across the entire mid Willamette Valley! It’s clear now that we have either hit the upper end of my forecasted snow totals or surpassed them for this point in our winter storm with more on the way tonight through Friday morning.

At the moment we are currently in between the rounds of heavier precip, and the “heating of the day” has helped major roads clear up a bit, but conditions go down hill tonight as temperatures drop and as round #2 moves in, so don’t get stuck out there thinking all is well.

What’s ahead?

More snow tonight with freezing rain and sleet mixing in. This second wave of moisture still looks quite “juicy” lol with a solid half inch of melted down precip (or more) with round #2. I currently expect at least a little bit of freezing rain or sleet to mix in tonight before changing back over to all snow; however, models have already been trying to push the cold air out of here too quickly, and so for the moment I’m leaning towards more snow and not as much in the way of ice.

Either way, winds continue to breeze out of the north, and temperatures will be plenty cold enough that whatever falls from the clouds will be frozen or will freeze on contact (freezing rain). My best guess is an additional 2 to 5 inches of snow with some freezing rain. If this storm continues to overperform I could see us surpassing those totals too! There are always little twists and turns with our winter storms here…

Snow will come to an end Friday morning, but with the colder than expected temperatures and increased snowfall, we should plan on road conditions improving very SLOWLY through the day on Friday with side roads remaining in rough shape.

Refreezing Friday night with clearing skies will lead to more issues again on side roads and less traveled streets through early Saturday morning before finally thawing out the rest of the way.

One additional thing I want to mention is how the Salem Airport temperature sensor has been regularly reporting a bit warmer than surrounding stations. Even warmer than weather observation spots in downtown and east along Lancaster Drive. Mark Nelson posted this graphic from the other day showing just how off it’s been and that he has tracked this for a couple years now. He does excellent work for Fox 12 and I appreciate his attention to details and to locations outside the PDX metro if you ever need a good forecaster to watch on TV.

So if you’re curious why your weather sensor at home has you in the upper 20s, but your weather app says otherwise, well now you know! Even right now you can see it is way off compared to the rest of the city and local area sitting at 34° while the rest of us are in the upper 20s to around 30°.

Stay safe, and keep on enjoying the snowy and wintry weather!! 🙂

Snow and ice storm

Less then 12 hours from now I anticipate Salem will be a winter wonderland with a coating of snow and maybe some freezing rain and sleet mixed in too. This is the perfect setup for snow and ice here in the valley. A cold northerly breeze is pumping in modified arctic air and very dry air too. This means our temperatures will drop even colder once the precip arrives very early Thursday morning. The process of the moisture taking or absorbing the heat out of the atmosphere is known as evaporational cooling.

Main message

Precipitation begins around 4 to 7am Thursday morning. Expect widespread snow accumulations of 1 to 3 inches. Sleet and freezing rain could mix in. Snowy and wintry weather lasts through around 10 or 11am.

Between 11 and 4pm Thursday not much will be going on. Additional showers of snow or freezing rain are possible, but nothing long lasting or widespread. It’s also likely that we “warm” up above freezing for a few hours in the middle of the afternoon due to the increased sun angle and lack of precipitation falling. Should precip continue heavier than expected than the whole brief period of melting goes out the window… Expect poor travel conditions even if we get some melting!

Thursday night through about 10 or 11am Friday morning will feature another surge of moisture. This second wave has potential to really drop the hammer either in the form of heavy freezing rain, heavy snow, or a mix of both.

Bottom line is we have a solid snow and ice storm on tap beginning very early Thursday morning and lasting through the first half of Friday. Too soon to make the call for road conditions Friday night (Valentine’s Day).

More details

So I’m quite confident we have a snow and ice storm on the way, and I’m confident we will be more than cold enough for it to stick and accumulate on all surfaces. What is still up in the air is how much of precipitation falls all together, and how much falls as snow versus freezing rain. Check out how much precip this particular model has falling through Friday 8am.

That could be a whole lot of snow, or a scary amount of freezing rain, or a mixture of both, but then we have other weather models showing not quite as much precip. This next image below also is forecasting total precip, but it cuts the total literally in half. Sure it still gives Salem a hefty total good for 5 to 7 inches of snow, but that’s only half of what that first image advertised.

This next image shows that second batch of moisture directly over the Willamette Valley Thursday night into early Friday morning. The “SLE” is the Salem Airport. You can see how we are right on the edge of the freezing rain and sleet (pink coloring) and the heavy snow (blue coloring).

The important message is that we have a snow and ice storm on hand. How much do we get and is it more ice or more snow is a question we just can’t know this time around until it happens. Be prepared for icy roads, snowy conditions, and possible power outages. Truth is that around here it only takes an inch or two of snow to mess things up on the road anyway, so what’s an extra half foot between friends right? 🙂

Stay safe and enjoy the snow and ice!
