Weather Synopsis for Friday & Saturday
A closed low drops south off the California Coast on Friday while the main jetstream resides well to our north over Canada. The result will be generally quiescent weather over our region with a warming and drying trend.
The aforementioned closed low combined with the remnants of a frontal boundary maintain mostly cloudy skies across the region Friday morning. There's just enough lift along with light generally S winds in the Mt Hood and possibly Mt Adams area for a few hundredths of an inch of precipitation today, before chances diminish in the afternoon as skies gradually clear across Washington State. Although 5000 ft NWAC stations start the day near or slightly below the freezing mark, expect freezing levels to rise to around 6000-7000' by the afternoon.
Friday night features mostly clear skies and further warming aloft as freezing levels rise to 7000-9500 ft. Saturday will be significantly warmer than normal for mid-April with freezing levels rising to 8500-10000 ft. As the closed low into the great basin, some mid-level clouds and some very light precipitation may rotate back into the Mt Hood area on upper-level E flow.
