Into the mountains for tonights forecast. There’s been a bit of a warm up for Montana recently. Will it last?
At 953PM, MT, Missoula was reporting a temperature of 48 degrees with overcast skies. The Pineapple Express has set itself up and is importing a great deal of moisture into the Pacific Northwest. An area of low pressure in southwestern Canada is tapping into this moisture and redistributing it through the northern Rockies. This is leading to the widespread overcast and fairly warm temperatures for Missoula, though the topography of the region is helping prevent rain.
Moist flow will continue to rush into western Montana through day tomorrow. A particularly heavy round of rain will arrive in the area in the early morning tomorrow, and will be laden with enough moisture to lead to rain in Missoula. Tomorrow won’t be a wash by any stretch of the imagination, but there will be a chance for showers through the day. The chance for rain will continue into the early morning Sunday, but a strong surface low developing within the Express will emerge off the northern California coast. It will work to draw flow towards itself, and thereby bring dry air to the city. Ultimately, expect the system to slam back into Missoula on Monday, but for this forecast’s purposes, expect a greatly improved day on Sunday.

Currently, models aren’t doing great with temperatures (too cold) and then, tomorrow, forecasters are doubting what the guidance is suggesting, and forecasting well below model guidance. I am splitting the difference and going closer to what the super computers are suggesting. Here is the satellite imagery, showing the very active picture for the northwest.
