September 10, 2021
Record heat in some places occurred on the valley floor yesterday. Lemoore soared to 110 with most locations between 105 and 109. It was an odd day all the way around as a batch of monsoonal moisture became entrained in a trough of low pressure moving through the Pacific Northwest and northern California. This added enough lift to the atmosphere for sprinkles to occur. Isolated pockets actually picked up measurable rain with Visalia picking up .03 and Fresno and Visalia .04. the marine layer has jumped up to 2,500 feet. As the onshore flow increases today, marine cooled air will move down the valley. Readings will fall from well above the century mark yesterday into the mid to upper 90s today through the weekend. As the trough moves through, upper level high pressure over the Desert Southwest will expand into southern California. In fact, an elongated trough of low pressure will stretch from off the southern California coast, eastward into the southern US. The main storm track will be zonal and will run through the Pacific Northwest and British Columbia.
Forecast: Partly cloudy this morning with a chance of a few sprinkles over and near the foothills. Mostly clear tonight through Sunday. Mostly clear Sunday night through Friday.

Two Week Outlook: September 17 through 23: This model indicates a trough of low pressure will dominate most of the western US, including California. Temperatures will begin to fall to near to even marginally below average, however precipitation will continue to be unlikely.
September: This model indicates high pressure will be dominant over the desert southwest and California. The chance for precipitation will remain very low. Temperatures will be marginally above average.
September, October, November: If this model has any credence, the dominant pattern of the summer will continue. Expect temperatures to be marginally above average as we head into fall. Precipitation will generally be below average, although the chance will begin to increase as we head into November.
Winds Discussion: Winds will increase out of the west or northwest through this evening at 10 to 15 MPH. Gusts over 25 MPH will be possible, especially along the interstate 5 corridor. Winds will begin to diminish after midnight. Winds Saturday through Monday will be mainly out of the northwest at 5 to 12 MPH afternoons and evenings and less than 6 MPH nights and mornings with periods of near calm conditions.
Rain: A few sprinkles are still possible for a time this morning, mainly near the Sierra Nevada foothills. Nothing measurable is expected, however. Expect dry weather tonight and for the next 7 to 10 days.
