Justin’s Tuesday Forecast Discussion:
Another bitterly cold night across most of the state as high pressure slowly moves east. Lots of cold air trapped at the surface and because highs only made it into the upper 30s, we’re falling fast into the mid 20s again for overnight lows. So expect another round of widespread frost and freezing fog early Thursday.
By the afternoon, 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 brief periods of freezing rain (mainly in the northern end of the Willamette valley). The timing isn’t necessarily set up for icy conditions, but we may see another chance of some icy roads overnight into Friday with a few leftover showers. Rain chances are very light overall. Highs will be a tad warmer, topping out around 40.
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 and maybe a few isolated showers inland. The next rain chances aren’t here until midweek next week.
Have a great Thursday!
