.SHORT TERM…
SW flow will be over the region tonight with shower activity briefly trending dry with some isolated showers beginning to move in again around sunrise. SW winds will trend lighter tonight becoming calm to light near sunrise. Dew points are progged to be in the mid 30s under mostly cloudy skies. Temps aloft will be cooler with potential overnight lows based on temps aloft alone in the low 30s. Active weather will keep most observed lows in the low to mid 40s.
An upper trough will continue to dig over the PNW as an upper low moves into the region. Scattered to isolated rain showers will move in from the W/SW. Shower activity will trend drier overnight but some isolated showers will remain in the forecast thru the night. 24 hour precip totals for Saturday look to be 0.10” or less. Winds will be mostly variable and light, becoming a bit breezier near sunrise as the upper low encroaches, tightening gradients. Dew points are progged to be in the mid 30s under mostly cloudy skies with mid and high level cloud decks. Temps aloft will be cooler with potential overnight lows in the low 30s. Active weather and mostly cloudy skies will keep overnight lows mostly in the low to mid 40s.
.3-5 DAY…
A robust upper trof will continue to amplify over the western U.S. with an upper low driving the weather across Washington. This will essentially keep on and off scattered to isolated rain showers in the forecast Sunday and Monday. There may be some increase in shower activity during the afternoon as chances for convective showers increase. Rain totals for the two days looks to be around 0.10” or less for the districts. Winds will be W/NW and breezy to windy Sunday with gusts around 30-35 mph. Winds will be generally light Monday. A transient ridge will pass thru the region Tuesday with mostly dry and fair weather expected. Sunday will be the final cool day with a warming trend to begin Monday. Even with cool temps aloft Sunday night frost risk looks minimal with most residing in the low to mid 40s.

Extended Outlook
Model solutions indicate a potent upper low circulating over the Gulf of Alaska thru the extended period. This will place Washington under warm and moist SW flow. There will likely be an opportunity or two for scattered to isolated rain showers as shortwaves embedded in the mean flow move across the region. Guidance indicates the first opportunity to be in the Thursday night time frame with another possibly again late Sunday with timing likely to be adjusted slightly. Temperatures aloft will be rather warm thru the period with potential overnight lows remaining above freezing. Daytime highs will likely range in the upper 70s to low 80s with overnight lows mostly in the upper 40s to low 50s.
