As I mentioned on the 10 & 11pm broadcasts tonight, March 28th will definitely go down as the first widespread "thunderstorm" day in the spring here in the Northwest. We recorded over 200 strikes across Oregon. They were spread all across the state from the Coast to the Idaho border. Scattered storms developed and moved north, away from a California system supplying the moisture.
Tomorrow the flow overhead turns onshore, which should give us lighter afternoon showers. Onshore flow also means a bit more cloud cover and cooler temperatures.
Long range maps show this active pattern will continue with deep troughs dropping in towards California, which gives us southerly flow and moisture, then cooler air as they move on through. Those of you looking for 70 degree weather will have to wait into the first week of April at least….Mark
