.SYNOPSIS...High pressure will bring another dry and warming day
today before a fast moving and potentially windy storm system
drops into the Great Basin on Thursday and Thursday night. High
pressure will return for more springlike conditions for the
.DISCUSSION...A few high clouds are drifting overhead as they
spill over a Pacific ridge extending along the west coast. This
ridge will provide generally mild conditions today with
temperatures pushing a few to several degrees above climo.
These tranquil conditions will be briefly interrupted as the next
frontal system drops through the Pacific Northwest and into the
Great Basin Thursday.
Models handle this system similarly and this inside slider type
trajectory will be a mostly dry event for our area. Precipitation
chances will be mainly confined to the mountains as the system
passes Thursday, though can`t rule out a few light showers in the
lower elevations north of Kern County. Snowfall will mainly occur
above 6-7 thousand feet with no more than a few inches expected at
the highest elevations. The main effect of this frontal trough
will be strong gusty winds. Gusty west to northwest winds will
develop by late morning Thursday as the system moves through the
region. Winds will likely gust around 30 mph during the afternoon
Thursday, with some locally higher gusts, especially through
westside passes. 50 to 55 mph are likely across the Kern County
mountains and desert areas, locally higher in the typically windy
spots. A wind advisory remains in effect here Thursday afternoon
Model agreement continues into the weekend as the low pressure
system moves into the southwest US and high pressure rebuilds
across our area. This will bring dry and calmer conditions with
temperatures trending back above climo. Model solutions then begin
to drift apart a bit for the first part of next week but generally
agree on weakening the ridge as a trough moves into the region
around Monday. Precipitation chances with this passing trough are
minimal and it is expected to mainly bring another round of gusty
winds and cooler temperatures for the early part of next week.
VFR conditions are expected across the central CA interior for the
next 24 hours.
