Slightly Cooler
Expect another unseasonably warm day on Monday! The overall air mass cools about 5ºF, but highs will remain roughly 10ºF above normal for this time of year with widespread upper 60s and 70s. Enjoy the warmth, because much cooler weather will then be on the way. Clouds will increase Tuesday as a storm system weakens and stalls offshore. A developing system will then push in from the west and draw in the lingering moisture from the first system, taking aim at the U.S. West Coast on Wednesday. We’re likely to see a strong frontal boundary paired with a deep moisture plume late Wednesday into Thursday which is likely to bring heavy rain and gusty winds to the region. There is flooding potential with this storm, especially for roadways and small streams. Finer details will have to be tuned in the coming days, but heavy rain is looking likely at this point.
AIR QUALITY: Good
Overnight: Mostly clear and mild. Lows in the 40s to low 50s.
Monday: Mostly sunny and warm, but not as warm as Sunday. Highs in the upper 60s to mid 70s.
Tuesday: Increasing high clouds with some low to mid level cloudcover on the coast later in the day. Cooler, with highs in the 60s.
Extended: Rain & wind pick up on Wednesday, becoming heavy after dark. Heavy rainfall will likely last into the early morning hours before tapering off. Small stream and street flooding looking possible. Rounds of showers will then continue on Thursday and taper off on Friday. Expect much cooler air with highs in the 50s Thursday into the weekend. Another system is then likely in the Sunday/Monday timeframe.
