A weak trough of low pressure off the coast of the Pacific Northwest will strengthen over the next few days, resulting in a cooling trend. Readings will slowly come down each day, by this weekend they will have fallen below average. This will give us a nice summer respite from the heat. The marine layer has deepened considerably over the past 24 hours. According to the naval installation at Monterey, the depth of the marine layer has gone from near 1,000 feet yesterday to 2,200 feet this morning. Pressure is lower over the valley than off shore. For example, the current altimeter reading at San Francisco is 30.03 inches of mercury while at Fresno the reading is 29.94. That’s not a big difference in pressure but should be enough to tug modified marine air down the valley. Most locations will be below the century mark today then will fall into the mid 90s Friday and the low to mid 90s Saturday. The trough will make its move inland Monday and Tuesday. High resolution models are indicating many locations may not even reach the 90 degree mark Monday and Tuesday, resulting in perfect weather for the Fourth of July. Looking down the road to Wednesday and beyond, upper level high pressure over the Desert Southwest will again expand northward and westward for our next warming trend which may allow us to revisit triple digits as we close in on next weekend. This weather note as well. Debris clouds from a former tropical storm are off the southern California coast and are becoming entrained in a southwesterly flow aloft. These clouds will move over southern California over the next 36 hours and some may become visible over the south valley later today through Friday.
Forecast: Mostly clear skies through Sunday except for occasional cloudiness later today through Friday in the south valley. Mostly clear Sunday night through Thursday with a cooling trend through Tuesday.

Two Week Outlook: July 7 through July 13 A broad expanse of high pressure centered over the Desert Southwest will move back overhead during this period for above average temperatures. Monsoon moisture may trigger afternoon and evening thunderstorms over the Sierra Nevada with occasional clouds over the valley floor.
June: This model shows a high center over New Mexico and Texas extending into California for marginally above average temperatures for the month with the usual dry conditions prevailing.
June, July, August: This model is hinting at a possible active monsoon season this year once we get into July and August. It’s possible we could see more than the usual amount of afternoon and evening thunderstorms over the Sierra Nevada but the valley will be typically dry with above average temperatures.
Wind Discussion: Winds will be generally out of the northwest at 8 to 15 mph through Sunday. Gusts to near 25 mph are possible, mainly along the west side but locally elsewhere.
Rain: Expect dry conditions for the next 7 to 10 days.
Frost: All locations will be above freezing tonight and each night for the foreseeable future.
