Cool, breezy conditions with mostly dry weather will be present
across central California into next weekend.
Some mid level clouds moving into the Merced and Yosemite area due
to an upper low moving over the Bay Area. Otherwise mostly clear
skies across central CA. Satellite images show little moisture so
do not expect any precipitation with this system. However
conditions will turn breezy across much of the district this
afternoon. Winds will shift Northwest with a moderate upper level
jet across central CA. Expect gusty windy conditions to continue
for much of tonight in the Kern county mountains and desert. Think
winds will remain below advisory level until late Monday.
The upper low will usher in a cool NW flow...with falling 500 mb
heights across the region resulting in a cooling trend. Temperatures
should cool between 5 and 8 degrees today. Zonal flow will remain
for much of the week keeping cool temperatures near seasonal
Additional upper level disturbances will move through the Great
Basin..turning wind flow more Northwesterly Monday and continue
into at least Friday. A few showers will be possible over the
Sierra Nevada generally from Fresno County northward Monday
through Wednesday. However...the best chance of precipitation
looks to remain to the North and East of the area...but models
prog some light precipitation and a few scattered showers cannot
be ruled out.
Breezy conditions will develop across the area late Monday through
Monday night...especially over the desert and Kern County
mountains. These winds will develop due to strong upper level
winds and in response to surface high pressure strengthening over
the Eastern Pacific with surface low pressure over the desert
southwest. Operational models in fair agreement for next week.
Progs show a large upper low in central U.S while amplifying a
Ridge in the Epac. CA will remain in between this two features
keeping strong NW winds aloft and maintaining windy conditions
through the end of the week.
VFR conditions will prevail throughout the central CA interior
during the next 24 hours.
