Today's Forecast

Updated Sunday 11:15 p.m.

What a weekend!  After making a stray appearance here and there on Saturday, the sunshine completely took over the I-5 corridor Sunday afternoon, boosting temps from Blaine to Battle Ground well into the 70s.  New record highs were set in many communities, including Bellingham (75), Olympia (73) and Sea-Tac (72).  The pumpkin patches were perfect, and the Dawg Dash at the UW was dry and warm.

The benign fall weather wasn't in place everywhere in Western Washington.  A slow-moving cold front edged in to the ocean beaches, and smothered Forks, La Push and Ocean Shores in a thick blanket of clouds and steady rain.  Gusty winds picked up ahead of the front, too, with gusts between 30 and 40 mph recorded from Long Beach to Whatcom County.

This front will eventually lean into Puget Sound, and we'll see increasing rain in Everett and Tacoma overnight.  Lows will drop into the 50s as the clouds and precipitation sock us in.  We'll wake up to wet pavement, so the morning commute may take awhile.

The rain will give way to scattered showers & sunbreaks by the afternoon, and we may even hear a rumble of thunder or see a flash of lightning.  Afternoon temperatures will tumble way back into the low 60s as cooler air moves in.

The next system pushes in for increasing rain late Tuesday, and Wednesday will be soggy as the front crosses over the Pacific Northwest.  Thursday and Friday also look rainy-at-times, and highs will cool back into the more 'October-typical' upper 50s.

Bottom line:  out with the warm and dry, in with the chilly and damp.  Drive carefully!
