Justin’s Tuesday Night Forecast Discussion:
A very warm day to finish out the ridge of high pressure’s hold on the Northwest. Highs in the Willamette Valley hit near 70 today! That’s almost 15 degrees above our usual high for this time of year. It’ll be long gone by this time tomorrow as an Arctic blast is on its way. A weak cold front will push through tonight, firing off a few showers overnight, but its what’s behind the front is what will change our forecast back to November.
Wednesday will see just a slight chance for a shower or two and sun breaks, but highs will be much cooler, in the mid to low 50s. Even cooler air will be in place for Thursday, I’m expecting highs to struggle to get into the upper 40s. With the low moving through on Thursday, the cold, unstable air aloft should provide a nice trigger for thunderstorms, especially if we see some sun breaks. Chilly overnights as well, dipping into the mid to low 30s.
As you might guess, snow levels will be falling quickly, down to 6500 feet on Wednesday, 2500 feet to near 2000 feet by Thursday and Friday. Pass level snow should start on Wednesday Be ready for some slick driving conditions by then. Ski resorts to get a nice four day stretch with some heavy snow showers at times.
The weekend quiets down a bit, Saturday should see the rain showers end for the day, highs bumping back into the low to mid 50s. But there’s more rain coming Sunday night and Monday.
Have a great Wednesday!
