Summary: A very cool zone of low pressure aloft stretches from the Canadian Rockies south/southwest into northern and central California. Much cooler air has moved in aloft over the past 36 hours. Roughly 48 hours ago, the freezing level taken over Oakland was near 14,000 feet while the latest overnight reading is 9,500 feet. This, coupled with cool air aloft and a robust onshore surface flow, means plenty of Pacific maritime air is invading the valley. The result is unusually cool summertime weather. From Fresno County north yesterday, readings did not reach the 80 degree mark but struggled into the lower 80s in the south valley. Today will be quite similar as the overall pattern has not changed much. The low will begin to weaken after Thursday, however pressure patterns will remain weak over the west, maintaining below average temperatures through the weekend. I can just see some LA camper up at Tuolumne Meadows where it was 25 degrees as of 5:00am. The coolest I could find on the valley floor was 45 degrees at Porterville. I took a glance at medium range models for late June and early July. The GFS model was indicating strong high pressure would be blanketing the west, resulting in hot weather. We’ll see if this comes to pass.
Forecast: Mostly clear and mild through Friday. Mostly clear Friday night through Tuesday with a slow warming trend.

Two Week Outlook: June 26 through July 2 This model is beginning to depict a high center developing over extreme over Mexico and southern Arizona and New Mexico, theoretically baking the Desert Southwest. Central California will be on the far northern fringe of this high, resulting in slightly above average temperatures and dry conditions.
June: Of course, this time of year, 30 and 90 day outlooks are virtually useless as they’re essentially the same every year. Basically light all day and hot and light all night and warm. Essentially for June, near average temperatures and dry..
June, July, August: The 90 day summary outlook is the same this year as it is every year. Generally dry with somewhat above average temperatures. The monsoon season hasn’t begun yet, so we’ll start taking that more seriously down the road.
Wind Discussion There will be periods of winds out of the west/northwest at 10 to 20 mph at times with stronger gusts possible through Thursday, mainly in the later afternoon through early evening hours. Winds Friday will be mainly out of the northwest at 8 to 15 mph.
Rain Discussion: Expect dry conditions for at least the next week.
Mid afternoon dew points: Mid to upper 30s. Kern: Low to mid 30s.
