Another Round Of Monsoon Moisture?

WEATHER STORY
It’s business as usual for late July weather-wise, EXCEPT for a possible return of monsoon moisture. The great monsoonal high sitting over the Four Corners Region continues to pump moisture north into the Desert Southwest. The overall weather pattern over the West Coast is pretty quiet, but there is a weak upper level low just off the California coast. This low will also act as a pump, pulling monsoon moisture into California late Monday into Tuesday. This moisture will brush past our coverage area Tuesday morning with a very slight chance of a shower or thunderstorm. This moisture is in the mid-levels and just deep enough to produce rain that could reach the ground, though likely not much—but also lightning. The threat will be highest to our north and east but that zone could expand into our area. It will be much clearer in the Monday model runs.

Beyond Tuesday, expect us to remain in our normal summer pattern with coolish, marine layer weather on the coast and warm/hot dry conditions inland through next weekend.

AIR QUALITY: GOOD

Overnight: Widespread low clouds for the coast and inland valleys. Patchy fog & drizzle possible. Lows mainly in the 50s. A few interior valleys may dip into the upper 40s.

Monday: Low clouds recede to and then hug the coast during the afternoon with highs in the 60s to around 70ºF. Inland areas will clear out with highs ranging from the 70s to upper 90s. Becoming windy for major inland valleys in the late afternoon and early evening.

Tuesday: Low clouds hang around the coast again, but could clear out a bit late depending on what happens with the monsoon convection to our north and east. We’ll see a very slight chance of a shower or thunderstorm, mainly in Santa Clara & San Benito Counties. Highs in the 60s-70s on the coast, 70s-90s inland.

Extended: Coastal low clouds and inland sun after AM valley fog. Coastal highs in the 60s-70s through the weekend with inland areas in the 70s-90s… slightly warmer late in the week into the weekend. High clouds will also continue to drift through at times.
