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!

Winter storm Thursday and Friday

This will be a very short post, but an important one. I’m confident a winter storm will impact our region beginning Thursday morning through at least Friday morning. I’ll have a nice post filled with more details and shiny graphics tomorrow. For now, plan on weather disrupting your daily routines beginning Thursday morning with rough travel conditions lasting through at least the first half of Friday. This means snowy and icy roads during this period of time – even during the daytime hours on Thursday.

The situation this time is much more simple compared to last week which is why I have such high confidence two days out. We are not dealing with isolated showers, the timing does not have to fall in the middle of the night, and we don’t have to worry about southerly winds. We will be plenty cold, and moisture will be abundant with chilly breezes continuing out of the north for the duration of this event. The perfect recipe for wintry weather.

How much precip will fall, and what form of frozen precip will we experience are the two big questions still up in the air. At the moment it looks like the Salem area will see a mix of snow, sleet, and freezing rain through the course of the storm. Temperatures will be below freezing all day Thursday through at least Friday morning, so accumulations will occur on the roads. My best guess would be 1 to 3 inches of snow, some sleet, and a little bit of freezing rain. Keep in mind forecasting snow totals is tricky when we are bouncing back and forth between snow and ice.

Friday afternoon or for sure by Saturday morning we should warm up to begin the melting process. It’s mid February, so the snow and ice won’t stick around super long, but for the two days it’s here, it will effect your life to a degree.

Happy Tuesday and stay safe out there. I leave you with a map of the regional temperatures as of 7AM this morning. Brrrrrrr!!!!!

Icy roads tonight

On February 8, 2025 By bryanweatherIn Salem Area Forecast, The Mountains and Beyond, WEATHER ALERTSLeave a comment

This past Wednesday was an exciting day. I would guess that everyone at least saw snow in the air. It did not stick in most places, but some neighborhoods got a brief coating of white, and the higher hills around town received accumulating snow. These showery patterns with southerly winds are always so borderline. So many factors to consider which really can’t be forecasted very well far in advance. Had we been two degrees colder, or had the showers arrived earlier while it was still dark then we could have woken up to a snowy or more like slushy winter wonderland. We’ve seen it go both ways here. Overall I’m fairly happy with how the forecast has gone. Hopefully I’ve portrayed just how tricky forecasting snow with this particular setup really is.

The forecast

A few very isolated showers tonight through early Monday morning, and by isolated I mean extremely isolated, but it’s just enough to keep us from being totally dry. I greatly dislike when the weather does that lol… Because of the showers, we also have increased odds of icy streets or even a random (light) dusting of snow – especially in the higher hills. Watch out for icy roads the next few nights and mornings.

Monday – Wednesday

Count on it being cold, but mostly sunny and dry. Lows in the lower 20s by Wednesday morning. This part of the forecast feels pretty certain to me. Highs will gradually cool off each day under the influence of a NE breeze.

Mon: Low of 28°. High of 44°.

Tue: Low of 24°. High of 42°.

Wed: Low of 21°. High of 39°.

Looking ahead

This coming week has the potential to be even colder with a more classic setup for widespread snow or ice. The ingredients will be in place. Cold air, winds out of the north and east, and a low pressure approaching from the southwest. This exact setup is how we get our biggest snow and ice storms. Some examples of this setup in the past include last January, the ice storm just before Christmas 2022, the big ice storm we saw in February 2021, and the snowstorm we saw (for you old timers like me haha) way back in December 2016. These are all examples of this “classic setup.” No southerly winds, no scattered showers like we have seen this week. Just cold air and steady precip. Still not an easy forecast, but several of the trickiest factors are removed from the equation in this scenario.

The first factor yet to be determined is how deep the cold air will be. If the cold air is shallow, we end up with more sleet or freezing rain – something we have seen more often these past several years it seems. If the cold air is deeper then we have the potential for widespread snowfall. I like to share the graphic below to help illustrate this point.

The track of the low pressure next week will also determine the impact on us locally. Too far south and we stay dry and cold, too far north and we see all rain or freezing rain, but if it goes somewhere in the middle then we end up with a nice snowstorm. I’ve drawn a few lines on the map below. This map shows low pressure (storm centers) for Thursday morning. Ignore the lows to west of the slanted line as they are part of another storm system. I’ve placed a blue smiley face to mark western Oregon hehe. In a nutshell, lows to the north of the top horizontal line would generally give us either rain or a brief shot of freezing rain or snow before changing to rain. Lows to the south of the bottom line would for the most part leave us high and dry, and finally, the majority of the lows between the two horizontal lines would give us a snowstorm.

So you can see why making a call on how much snow, or if it will even snow is not really possible just yet. History tells me that by Monday evening I should have a much better idea of what to expect.

We do know that it will be cold for the next several days. Again, keep an eye out for icy roads and parking lots, and have a fun and safe rest of your weekend! I’ll be sure to keep you all in the loop once details become more ironed out.

Quick update

On February 4, 2025 By bryanweatherIn Salem Area Forecast, WEATHER ALERTSLeave a comment

It’s late Tuesday evening, and time for a quick update.

Highlights

The amount of locations receiving snow tonight will go up dramatically compared to the past couple of nights/mornings.
Not everyone will see snowfall.
I’m going with nothing to 3 inches.
We could see snow showers on and off all day long, but the snow won’t stick during much of the day due to southerly breezes kicking in and “warming” us up to the upper 30s.
Roads will be clear most of the day.
As the winds calm down and the showers hang around Wednesday night which could give us a second round of sticking snowfall heading into early Thursday morning.

The main message is that moisture is dramatically increasing tonight through Wednesday night. Between now and roughly 10am anyone could see a coating of snow in their neighborhood. Our main issue the past two days with seeing snow is just a lack showers making it into the valley. Meanwhile, the coast has had no problem at all picking up a few inches of snow each day. These two images from the central Oregon coast show snow in Lincoln City and near Cape Kiwanda today. Pretty cool to see snow like this along our coast!

Tonight that is changing. Heavier and more numerous showers are set to move ashore overnight while we are cool and lacking a strong southerly breeze. This means anyone could see up to 2 or 3 inches of snow, but these are showers still, and I doubt everyone will get snow tonight.

It could snow all day tomorrow, but it likely won’t be sticking once we get past about 10am Roads should clear up quickly making travel tomorrow easy.

Wednesday night into Thursday morning could bring yet another round of snow showers as winds relax and cooler air moves back in. I hope to have a more detailed forecast tomorrow, so stay tuned!

Enjoy the snow and stay safe!

Forecast is still on track

On February 2, 2025 By bryanweatherIn Salem Area Forecast, WEATHER ALERTS1 Comment

So far today has been uneventful, but nothing that was not expected. Heavier showers are still very much possible this afternoon. These showers could briefly dump a coating of hail or graupel, or even snow if you are “lucky” enough. Just keep in mind that today was suppose to be the “mildest” day of the week, but if things had worked out just right some of us could have seen snow this morning. So hard to know in this showery pattern.

The temperature map from 10AM this morning shows the wide range of temps possible today due to stronger showers. Notice Tillamook was sitting at just 34° while Salem was 42°, so we can see what could have happened this morning or still could happen later tonight if we see a heavier shower.

The airmass is also cooling off still. The slider below shows the difference between our 11AM temps Saturday versus 11AM today. FYI, the slider tool seems to only work if viewed on the website. I think the email version of the post stacks the images for you to click through which still works, but it’s not as cool as using the slider tool haha!! 🙂 https://bryanweatheralert.com/

Many valley and coastal locations are running 3 to 4 degrees cooler than this same time yesterday, and in some cases even more. Expect additional cooling tonight which is why I’m slightly more confident in spotty light snowfall accumulations tonight through Tuesday. The forecast of nothing – 2 inches each night/morning remains on track with roads possibly being icy or snow covered during the nighttime and early morning hours. Roads during the day should be just fine. So far today we have seen now snow; however, Monday or Tuesday could easily be a different story. Hopefully that’s helpful in clarifying what is going on and what to expect.

The rest of the forecast below is just copied and pasted from Saturday’s post. I’ll try and have a fresh post either Monday or Tuesday.

Mon & Tue: A few snow showers are possible each morning. Some people will wake up to snow, some of us to ice, and some with mostly bare roads. Hard to pinpoint when we are dealing with showers. Snowy and icy roads should clear up by late morning each day. This means life should be able to go on as normal roughly 10am to 6pm each day. Nothing – 2 inches of snow possible each morning. Anything that falls out of the clouds during the daytime hours will be in the form of snow thanks to the cold atmosphere, but it’s much less likely to stick during the day unless you find yourself at a higher elevation.

Wed: More widespread snow showers likely. 1 – 4 inches of snow possible at any elevation and even during the middle of the day as colder air works it’s way south. Roads could be bad all day long Wednesday. Subject to changes still.

Thu: Back to sunbreaks & scattered snow showers. Another inch or two of snow is possible during this time frame, and colder temperatures will make it tough for roads to melt off.

Super Bowl weekend and the week after look cold. Way too far out for details, but strong signals that we remain in a wintry pattern with more snow opportunities likely to present themselves.

Preparing for wintry weather

Practical steps/most important info

Forecasting way out in time can be tricky, but it is very clear to me that we will be dealing with icy roads, snow, and cold at various times for the next few weeks. There are strong signals we will be in this wintry pattern for awhile. If you have snow tires and you think you would use them over the next few weeks then this weekend is the perfect time to put them on.

In the forecast below I’ve highlighted road conditions with red font, and important messages and snow totals in bold font.

If you don’t like driving in the snow or on icy roads, and you have a flexible schedule, then run your errands this weekend or else Mon & Tue afternoons. Plan on the nights and mornings being the worst for driving, and plan on slippery roads possibly all day long on Wed & Thu.

The current forecast for each individual day is just the best guess I can give with the information at hand. Don’t focus on details too much. Just keep in mind your travel plans and daily life could be effected by snow or icy roads pretty much each night and morning this week, and possibly all day long Wednesday and Thursday.

Details

Sunday: Anyone could wake up to a little snow. Yes, this will be our first shot as seeing snowfall. Wet snow, graupel, and rain are all likely with the heavier showers during the day. Roads could briefly become covered, but afternoon temperatures will melt things off. The vast majority of roads tomorrow should be fine. Chances for snowy roads always go up with elevation in this type of pattern. Expect a few sunbreaks at times during the day, but not as many as we have today. Estimated radar for Sunday morning around 8am does a good job at conveying the main message of scattered showers and snow showers.

Mon & Tue: A few snow showers are possible each morning. Some people will wake up to snow, some of us to ice, and some with mostly bare roads. Hard to pinpoint when we are dealing with showers. Snowy and icy roads should clear up by late morning each day. This means life should be able to go on as normal roughly 10am to 6pm each day. Nothing – 2 inches of snow possible each morning. Anything that falls out of the clouds during the daytime hours will be in the form of snow thanks to the cold atmosphere, but it’s much less likely to stick during the day unless you find yourself at a higher elevation.
