829am PDT Sunday Oct 25 2020

A rather chilly morning across Western Washington with temperatures in the upper 20s to mid 30s. Temperatures in the mid 40s to low 50s in spots by this afternoon. Dry weather into early this week with an upper ridge offshore of the area.

Synopsis
Dry weather with chilly temperatures will continue into Monday and then temperatures will gradually moderate through the week. A front will reach the area later this week.

.SHORT TERM /TODAY THROUGH TUESDAY/...Cool and crisp today. High pressure and offshore flow is giving us cool and dry conditions across western WA. Temperatures in the interior are mainly in the 30s this morning with dew points in the 20s - the coldest conditions we've seen so far this season. The Frost Advisory remains in effect this morning with areas near or below freezing. Up north, winds have been gusty in the North Interior but will gradually ease. Otherwise, sunny skies this afternoon with temperatures mostly reaching the 40s.

Dry northerly flow will continue into Monday. Lows continue to trend below normal with temperatures near freezing. Although, it'll be a few degrees warmer (compared to today) thanks to increasing mid and high clouds. Highs will be near 50 degrees.

A ridge over the West will flatten over WA next Tuesday as a warm front clips southern B.C. This system may clip western WA for a period of light rain (mainly bear the Canadian border). Temperatures will moderate and trend closer to normal. 33

Long Term - Wednesday Through Saturday
The ridge rebuilds over the Pac NW on Wednesday while a trough digs offshore. The flow then turns more zonal thereafter as weak disturbances tracks through the region. The coast and mountains will see a return of rain with generally light precipitation in the interior. The offshore trough, mentioned above, may eventually shift inland late in the week. 33

Marine
Breezy northeast Fraser outflow winds continue this morning, but will gradually ease toward mid-day. As a result, the current Small Craft Advisories for the Strait of Juan de Fuca and northern inland waters have been extended through 11 AM. East winds through the lower Chehalis and Grays Harbor also continue to surface over the coastal waters, so will also maintain the advisory for the southern zones of the coastal waters through the morning. Seas will continue to subside over the coastal waters today, generally remaining in the 5-7 ft range through around Tuesday. Expect generally light winds over the coastal waters Monday, with a return of southerly winds possible toward midweek as a weak front may approach.
