A very short post today. We have a typical thunderstorm pattern for summertime here. Southerly/southeasterly flow aloft is bringing monsoonal moisture to the region. This flow favors thunderstorms to develop over the Cascades, central, and eastern Oregon; however, it can lead to some isolated storms or leftover showers to drift NW over the valley.

In fact, the clouds we saw this morning are a result of the same scenario. The difference is that moisture and instability increase tonight and Thursday. This means showers could drift over the Willamette Valley at any point tonight through Thursday. Nothing long lasting or widespread. Just know that a brief disruption to our regular dry summer weather will be taking place and showers are possible.

Dry summertime weather returns on Friday.

Take care and stay safe!
