Justin’s Monday Forecast Discussion:
High pressure planted on top of Western Oregon will keep us very cold tonight. Widespread frost is a sure bet early Wednesday morning as most areas will start off in the mid to upper 20s. In the valleys, expect another round of freezing fog making for some slippery roads. The last day of clear skies is on tap for tomorrow, with some high cirrus clouds moving in by the evening. Because of the cold start, highs will be cold again, topping out in the upper 30s.
Thursday a weak low swings through the state but it won’t be very strong because of the dry/cold air in place so precipitations chances will be isolated to lightly scattered. However, because the Arctic airmass is wedged in to the valley, there’s a chance we might see some light snow flakes early Thursday and maybe some freezing rain later in the day (mainly in the northern end of the Willamette valley). So we’ll keep watch on that.
Highs start to warm back into the mid 40s by Friday and Saturday. Another storm gets close to the coast but breaks up and heads south into California. It should keep us cloudy for most of the weekend but I don’t see much chance for rain with the exception of some drizzle at the coast at times.
Have a great Wednesday!
