Clouds are increasing and a temporary change is ahead. Prepare for light rain to sweep over western Washington Monday morning and create slippery roads during the commute.

A trend set by the last 4 Mondays continues; every Monday has had rain over western Washington! It hasn't always been over the same places but, it is kind of creepy...which is perfect for October! Tomorrow is no exception!

Monday's steady morning rain will turn to scattered showers by the noon hour. A cold front sweeps across the state and leaves rain showers behind. In the afternoon, most rain will be focused in a Puget Sound Convergence Zone between Seattle and Everett. Rain amounts will be in a range from 0.10" to .30". High temperatures will be cooler in the 50s.

The convergence zone of rain will taper off overnight into Tuesday morning when spotty light rain or drizzle continues in these areas, also along the Coast and over the Cascade foothills. The wet, cloudy weather will dry and partially clear Tuesday afternoon, changing to partly sunny skies. With the sun, high temperatures will slightly warm to the low 60s.

Temperatures will continue warming up each day this week as high pressure and a warming airmass (thermal trough) combine to provide sunny days after morning fog or low clouds, Wednesday through the next weekend.

We have an upcoming stretch of Autumn weather that brings ample opportunity to be outside and accomplish any number of #SoNorthwest activities!

High temperatures for Thursday through Saturday will be under the influence of the thermal trough that enhances easterly, offshore, flow and pumps up temperatures well above normal. Highs will be in the low to mid 70s for the end of the week including Saturday. On Saturday morning, marine clouds return to our coastline and the beaches will cloud up and cool. Sunday will still be warm inland with sunshine but subtle changes will occur indicating a new frontal system that brings rain and breezy wind along with a cool down for ....yes, Monday.
