areas this morning.
An upper level disturbance just offshore will move slowly east and inland
over Washington Sunday. It will generate clouds and showers
beginning later today and continuing into Sunday with best chance of
rain in the valleys tonight. Cooler air comes in with this disturbance
and with clearing expected Sunday night, colder locations in the upper Yakima
valley could fall into the upper 30s Monday morning. Another front
moves in from the Pacific on Tuesday bringing a chance for a little rain
in the valleys. This will be followed by fairly cool air Wednesday
and Thursday and colder locations in the Yakima valley could see readings
in the low to mid 30s Wednesday and Thursday morning in the absence of clouds
and wind.
