Area Forecast Discussion
National Weather Service Sacramento CA
355 AM PDT Thu Aug 15 2019
.SYNOPSIS...
Hot temperatures next couple of days with an excessive heat
warning today and Friday valley and foothill locations. Cooler
over the weekend with below normal temperatures by Sunday.
Warming slowly through next week to a little above normal. Mainly
fair skies through the extended period with no precipitation
expected interior Northern California.
&&
.DISCUSSION...
High pressure over the west coast will bring fair skies and very
warm to hot temperatures today. Marine layer is squashed down to
below 500 feet and delta breeze is at a minimum so no coastal
stratus is expected within the CWA today. Overall airmass is
forecast to be just a bit warmer than on Wednesday so today's
highs should come in just a bit warmer most areas. This will put
daytime highs at the highest so far this year at some locations
and a excessive heat warning for the lower elevations and
foothills will continue. A weak upper trough will drop into the
Pacific Northwest on Friday bringing a slight cooling over Norcal
but temperatures will remain well above normal. A slightly
stronger upper trough is forecast to develop along or just off the
west coast over the weekend. Main effect will be to bring down
daytime temperatures to just a little above normal on Saturday to
actually a few degrees below normal on Sunday. No precipitation or
even significant cloud cover is expected with this system but
marine layer will likely deepen and coastal stratus may redevelop
enough that combined with an increased delta flow may make it
into the delta and valley during the morning hours.
&&
.EXTENDED DISCUSSION (Monday THROUGH Thursday)...
Ensemble solutions continue to indicate upper ridging over the
Desert Southwest gradually expanding westward through the period.
Therefore, at or above normal temperatures are anticipated early
next week into mid-week. Temperatures will be right around
average on Monday, then trend above seasonal normals the rest of
the forecast period. Most Valley locations should see temperatures
generally in the mid to upper 90s, while highs around 100 are
expected over the northern Sacramento Valley.
&&
.AVIATION...
VFR conditions next 24 hours. Winds will be generally light,
under 10 knots. Local gusts 15-20 knots possible in the Delta
vicinity.
