area forecast discussion
national weather service sacramento ca
910 am pdt Mon jul 24 2017

Synopsis
Slight chance of afternoon and evening showers or thunderstorms
across portions of the interior mountains through Tuesday. Cooler
today and tomorrow with near normal temperatures, then warming
remainder of the week.

Discussion
580 dm upper low centered about 110 nm west of kuki will be main
weather feature for interior norcal over the next 48 hours.

Satellite imagery showing area of ACCAS rotating around western
and eastern portions of this feature this morning. Marine layer
has deepened in response to the low and is currently around 1900
ft thick at fort ord. Moderate flow through the delta this morning
is advecting some cooler marine air into portions of the central
valley. Low will provide some synoptic cooling across the cwa
today with greatest cooling expected in delta influenced areas.

Nam GFS elevated instability progs showing increased 700-500 mb mu
cape and higher tt values to support slight chance of isolated
showers thunderstorms over higher terrain of eastern shasta and
western plumas counties, and near sierra nevada crest this
afternoon.

Gfs NAM ec similar in slowly drifting low west today then
quasistationary INVOF of the coast Tuesday, filling it slightly.

Greater cooling expected over the forecast area tomorrow with high
temperatures forecast near normal. Best potential for deep moist
convection looks to be over the higher elevations of the coastal
range, shasta, western plumas, and sierra nevada in the
afternoon early evening.

Upper low progged to progress slowly Tuesday night into
Wednesday, weakening to trough Wednesday night as it pushes ene of
the forecast area. Potential for any mountain shower thunderstorm
activity looks less likely Wednesday. Temperatures rebound a few
degrees Wednesday as upper low weakens.

Heights increase over the area Thursday as upper ridging from the
desert SW expands NW towards norcal. Dry weather expected Thursday
as triple digit heat returns across much of the central valley.

Pch
.Extended discussion (Friday through Monday)
upper ridge rebuilds across interior norcal late this week into
the weekend. This will result in daytime highs about 5-10 degrees
above normal. There are model differences in terms of the position
and strength of this ridge. At this point, the ECMWF is the
further westward and strongest solution. Thus, how much warming
will occur over the weekend remains in question given model
uncertainty. Dry weather is expected across interior norcal during
the extended period. However, the GFS is indicating an embedded
disturbance in the upper flow that could trigger some afternoon
shower activity near the sierra crest on Sunday. Have kept the
area dry for now given model uncertainty.

Aviation
Vfr conditions the next 24 hours across interior norcal. Winds
will remain light today, except gusts to 25 kt near the delta and
over higher terrain. Slight chance of isolated thunderstorms over
higher mountain terrain between 22z-03z.

Sto watches warnings advisories
None.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
