SYNOPSIS. Scattered showers over the high Sierra into this afternoon and evening. Afterward, dry weather will be the rule over the district through Saturday night. Gusty winds can be expected through and below the Kern county mountain passes through this evening. A storm system will bring rain and mountain snow and unseasonably cool temperatures to the region Sunday through Monday. Dry weather and near normal afternoon temperatures will return by mid-week.
DISCUSSION. Cumulus clouds and a few showers developing over the sierra this afternoon. Otherwise mainly clear skies across the central CA interior. Temperatures warming to above normal today but still remain in the low 80s through tomorrow as a ridge over the coast builds inland across CA. Model progs in fair agreement that a late season storm will impact the district starting Sunday into Monday. Satellite images show the large weather system over the gulf of Alaska at the moment. A leading trough will push through CA on Saturday bringing a stronger onshore westerly flow. Conditions should turn cooler and breezy across central CA with strong gusty winds over the Tehachapi mountains and Mojave desert area. Models bring measureable precipitation across the north half of the district Saturday night. Additional disturbances will bring a cold front southward into the south valley on Sunday. Strong winds aloft from the WSW will enhance precipitation amounts over the sierra front range due to upsloping wind flow. Models indicate rainfall amount from half to two inches possible with the higher amounts towards the Yosemite high country. Snow levels start about 6500-7500 and lower to near 5500 feet Sunday night with the cold core of the low moving through north CA. Precipitation diminishes early Monday morning as the system pushes east of the sierra. Models show instability and another disturbance moving across CA Monday afternoon, thus a few thunderstorms will be possible over the high sierra. A winter storm watch has been posted as this late season storm could bring heavy snow above 6kft. West side of the valley may see much lower rain amounts due to rain shadow from downsloping flow off the coastal range. Tuesday could see lingering effects of the storm as ensembles lean in the direction of another ridge pattern by mid- week. Uncertainty is still to high to call the next ridge a blocking pattern, but, with on a few ensemble members attempting to break down the ridge, the ridge pattern make exist over the West Coast for several days.
AVIATION. A slight chance of afternoon convection through 03Z Friday above 4000 feet. Surface wind gusts in excess of 35 knots can be expected through and below the Kern County mountain passes until 09Z Friday. Conditions improving toward VFR conditions across the Central California Interior after 10Z Friday.
