The strong weather front that dumped heavy rain on the region last night is moving quite rapidly eastward with a mass of cool air moving in behind it. Our higher level model becomes more zonal with low peaks. North central Washington weather today will feature rising clouds and cool temperatures with afternoon highs around 60 degrees. Clouds will fill in overnight from the southwest where the next moisture plume will enter the region below this weak ridge of high pressure. The forecast tomorrow will be cloudy and humid in the morning with partly cloudy skies in the afternoon with highs in the low to mid 60s.
The ridge is pushed eastward during the day Sunday as another low pressure system moves across the eastern Pacific and into north-central Washington in the afternoon. We have a 60% chance of rain on Sunday with high temperatures in the mid 60s.
Monday will be our warmest day with partly cloudy skies and highs near 70.
Mainly sunny but cooler on Tuesday as the next weather system approaches, highs in the mid 60s. The next storm Wednesday has a good moisture tap with rain likely and highs only around 60 degrees. Unusually cool and partly cloudy for Thursday with afternoon highs in the upper 50s.
