Area Forecast Discussion National Weather Service Hanford CA 227 AM PDT Thu Sep 16 2021
SYNOPSIS. A trough of low pressure will remain over the region today through Saturday bring a cooling trend. Today and Friday, high temperatures will cool to seasonal levels. Sunday and Monday, as a stronger trough develops high temperatures will cool to below seasonal values. Breezy to gusty winds will accompany the system passages, especially near and through coastal and mountain passes and in the desert areas. Light showers in the higher elevations of Yosemite will be possible for Sunday. By the middle of next week a warming trend once again returns.
DISCUSSION. Water vapor imagery shows the area under an extremely dry airmass which is typical for mid September. Other than wildfire smoke from both the Windy and KNP Complexes, skies are clear. Temperatures on Wednesday did not break 100 degrees at any of the San Joaquin Valley locations and only a couple of 101s were noted in the Indian Wells Valley.
Over the next few days, the area will remain in a weak or "baggy" trough and this will keep temperature trends neutral or show little change through Saturday. Change does arrive on Sunday as a rather vigorous trough of low pressure is projected to move across the Pacific Northwest and Northern California. The main results from this trough passage will be a big uptick in winds across the Kern County area and cooler temperatures area wide. Model projections of precipitation chances really end at Yosemite Park on Sunday and some light showers or high elevations snow flurries cannot be ruled out. Certainly not the first significant storm of the season, but a harbinger of the fall season in Central California.
Any increase in winds over the area is a concern for Fire Weather and the current wildfires will certainly react even to a modest increase in wind due to the extremely dry and parched fuels. Will need to continue very close collaboration with IMETs on both fires and assess the wind concerns as Sunday gets closer.
In the wake of the trough passage, winds go briefly offshore on Sunday night and Monday but speeds don't appear to be too strong. High pressure ridging then makes a return to the region for the remainder of the upcoming week.
AVIATION. In the Sierra Nevada and Kern County mountains, areas of MVFR visibilities are expected due to haze and smoke near active wildfires. Otherwise, VFR conditions will prevail throughout the Central California interior through at least the next 24 hours.
