All metro area temps are within 2 degrees of freezing at this hour, which is going to cause some issues for the evening commute and overnight on area roads.
Moisture is still falling from the sky, mainly in liquid form, but plenty of ice pellets mixed in. This will theoretically come to an end during the evening hours, definitely by midnight. At that time the whole band of clouds/rain/snow/frz.rain will shift to our south.
For the evening commute: Hilly areas are BELOW freezing right now and that won’t change, so the slight bit of solar heating we are getting (even through the clouds) will end at sunset. That means many roads in the West Hills and other hilly spots may freeze up. Freeways and highways will remain clear, but be careful elsewhere in the higher elevations.
Overnight: Several models push the entire band of clouds to the south after midnight. If so, skies will clear and temperatures will drop. Any road that is wet in the metro area could freeze for the morning commute. Of course some will have a chance to dry with the dry east wind blowing, but many will just freeze first. Allow extra time for the morning commute.
Friday: Sunny all day! It’ll be like our little winter event never happened. High temps in the lower 40s, but as opposed to Wednesday, the wind will just be a bit breezy from the east, not raging.
The forecast went well today here at FOX12, but what a close call. If the precipitation were a little heavier and temps 2 degrees colder, the NWS forecast could have easily verified.
I did totally miss with the snow forecast out in Washington County though…sorry Forest Grove!
