| Area Forecast Discussion National Weather Service Seattle WA 322pm PDT Wednesday April 17 2024 Synopsis Dry spring time weather with cool overnight temperatures and warmer than normal high temperatures will linger through the end of the work week. A weakening front will bring increased clouds, cooler temperature, and widespread precipitation Saturday afternoon and evening followed by lingering showers Sunday. Warmer and dry weather will kick the new week off Monday. Short Term - Tonight Through Saturday Sunny skies with widespread temperatures in the mid to upper 50s this afternoon. Mild conditions will linger into the evening setting up another night with temperatures on the cool side of normal. HREF and NBM ensemble data showing a 20-30% chance of temps dipping to freezing again tonight in the lowlands - mainly limited to Lewis County - cool, but a bit warmer than last night. An upper level trough moving down the backside of the offshore ridge late tonight and is expected to linger in the area into Thursday night. This continues to be a dry feature with perhaps a few more mid and high clouds and another sunny day. Thursday highs will be a little warmer - pretty solidly in the 60s. Friday looks to be the warmest day as the upper level trough kicks east, and the offshore upper level ridge building. Importantly low level flow becomes more easterly with gusty easterly winds in the Cascade Foothills. High temperatures will tip a bit higher into the upper 60s and lower 70s. Long Term - Sunday Through Wednesday The distribution in the ensembles continue to highlight the offshore ridge moving through Western Washington Friday night followed by a negatively tilted front Saturday. This will bring widespread rain and some gusty winds then lingering showers Sunday. There looks to be a good chance an high pressure to some degree Monday with drier and warmer weather to open the new week. There are enough members that keep some potential for precipitation Tuesday, but there are higher odds for generally dry weather lingering into mid week - typical Spring weather either way. Hydrology No river flooding expected for the next 7 days. NOAA Seattle WA Office: Watches - Warnings - Advisories WA...None. PZ...None. |
