Summary: The beginning of a noticeable cooling trend will start today, especially in the central and northern portions of the valley. Infrared satellite imagery shows coastal low clouds penetrating through the Delta while winds at Travis AFB in the Delta are out of the southwest sustained at 20 mph, gusting to 26. We can see that modified marine air is moving inland. So far, it appears it’s not flowing over the Coast Range further south. Locations from Fresno County south will warm into the lower 90s while mid to upper 80s will be commonplace from Merced County north. The marine layer has deepened to nearly 3,000 feet. However, the difference in pressure between San Francisco and Las Vegas is still minor, so the full force of the marine influence will not be felt until Wednesday. In the big picture, low pressure is located over British Columbia and the Pacific Northwest and is developing a trough into northern California. This will increase the onshore flow, lowering temperatures to near average beginning Wednesday and continuing through the weekend. Weak upper level high pressure will try to build inland by Monday of next week for a slow warming trend. However, no particularly hot weather is seen for the next ten days.
Forecast: Mostly clear skie through Friday night. Mostly clear skies will continue Saturday through Tuesday.

Winds tonight and Wednesday will be mainly out of the northwest at 8 to 15 mph. Gusts to 25 mph are possible, mainly near the gaps and passes along the Coast Range.
