Upper level high pressure is slowly breaking down and is sagging southward from its center off the coast of the Pacific Northwest. The marine layer is slowly deepening and is surging through the Delta. That modified sea breeze will eventually spill over other gaps and passes along the Coast Range further south. As a result, the low 90s of yesterday will be replaced by mid 80s today. At the surface, pressures are falling over the interior. The current surface pressure at San Francisco is 30.09 inches of mercury while at Vegas the current reading is 29.83. This pressure gradient will increase with time, resulting in gusty west to northwest winds down the valley. Already this morning, from Madera to Hanford, winds are out of the northwest at 10 to 15 mph. the low will sag further south, centering off the northwest California coast Monday and just off the central coast Tuesday. Light showers will spread down the Sierra Nevada Monday through Tuesday with even a chance of scattered light showers on the valley floor mainly near the foothills. It will be Friday of next week before a warming trend commences as high pressure builds in from the west. Temperatures will bottom out Tuesday through Thursday as temperatures struggle to reach the 70 degree mark. Readings in the traditionally cold spots will drop into the mid to upper 30s.
Forecast: Mostly clear skies through tonight. Mostly clear to occasionally partly cloudy Saturday through Sunday night. Variable cloudiness at times Monday through Thursday with a small chance of scattered light showers Tuesday through Wednesday, mainly near the foothills during the afternoons and evenings. Partly cloudy Thursday night. Becoming mostly clear Friday.

Two Week Outlook: May 13 through May 19: This time around, the main storm track is projected to be moving through the Pacific Northwest with a northwesterly flow over California. This will result in marginally below average temperatures with little to no chance of precipitation.
May: This model shows a dominant high stretching from Texas to southern California, resulting in somewhat above average temperatures for the month. It also gives an equal chance of above or below normal precipitation.
May, June, July: This model shows an early season high over the Four Corners region of the desert southwest, stretching westward to California, causing temperatures as we head into summer to be marginally above average. Since this is the dry season, the chances of precipitation will be very low
Wind Discussion: Winds through Monday will be mainly out of the west to northwest at 10 to 15 mph. Gusts to near 30 mph will be possible, mainly along the west side but locally elsewhere.
Rain: Dry weather will continue through at least Monday night. A cold upper low will sag southward and center just off the central coast Tuesday through Wednesday of next week. Light showers will spread down the Sierra Nevada and scattered light showers cannot be ruled out over the valley floor Tuesday through Wednesday, mainly during the afternoon and evening. Highest risk, low as it may be, will be along the Sierra Nevada foothills. Any possible amount will be generally at or less than .10. I’m not going to completely rule out an isolated thunderstorm Tuesday and Wednesday afternoons. If they do break out, rainfall totals in isolated regions will be heavier. Dry weather will return next Friday and will last for at least the next several days.
Frost: All locations will be above freezing tonight and each night for the foreseeable future.
