A couple nice & warm days are ahead for Western Washington, likely the warmest of 2023 so far! Let’s take a look at the European model forecast for Friday.

On Friday, expect highs in the lowlands to reach the upper 50s to low 60s, with some colder readings near the water. 

Saturday will be a great day, with pleasantly warm temperatures and partly-mostly sunny skies! Take a look at the European model forecast below.

Expect Saturday’s highs to be in the low to mid 60s across the lowlands, with the warmest temperatures away from the water and from Olympia southward. 

Unfortunately, the nice weather won’t last. Extended forecasts indicate that persistent cooler temperatures and wetter conditions will start Sunday evening and remain through next week.

A good way to see the extended outlook is the NWS Climate Prediction Center (CPC) temperature and precipitation outlooks for March 22-26.

Let’s start with temperature.

The CPC outlook shows a 50-70% probability of below average temperatures for Washington through the last week of March. At this time of year, “below average” generally means highs in the mid 40s to low 50s.

Next, the CPC precipitation outlook, also for March 22-26.

This outlook shows a 40-50% probability of above average precipitation for the entirety of the Pacific Northwest. At this time, extended forecasts show 0.75-2” of rain for Western Washington through next Sunday. Even more of a reason to capitalize on the sunny & warm weather this Friday and Saturday!
