Area Forecast Discussion

1134 AM PDT Sun Jun 4 2023

A warming trend is expected to continue today. This afternoon,
high temperatures will be around seven to ten degrees above
seasonal average. A few strong thunderstorms are possible this
afternoon and evening once again today in the Sierra Nevada and
adjacent foothills. A storm system will move over Southern
California beginning Monday that will provide at least a cooling
trend and increased winds in some areas.


Skies remain mostly clear throughout the central valley and
coastal ranges this afternoon with above normal temperatures
remaining for the majority of the area. Convection can be seen
beginning to build over the Sierra and will continue through the
afternoon periods. Instability will increase as we head later into
the afternoon and early evening hours bringing isolated showers
and thunderstorms back for the Sierra and lower foothills.

Monday will bring increased shower and thunderstorms to the region
as a closed low pushes eastward. Higher elevations through the
coastal ranges and the Sierra are forecast to see the greatest
chances for thunderstorm activity, but showers and thunderstorms
for the valley is not out of the question.

With this upper low, temperatures are expected to drop back below
normal for this time of year with much of the valley sitting in
the mid to upper 80`s. These cooler temperatures are expected to
remain in place through the weekend.


VFR conditions will prevail at all of the terminal aerodrome sites
through at least the next 24 hours. A chance of MVFR or lower
conditions near any thunderstorm in the Sierra Nevada and adjacent
foothills this afternoon and this evening.
