AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SACRAMENTO CA
922 AM PDT Fri Oct 10 2014

.Synopsis...
Near to above average temperatures will continue the rest of the
week and this weekend under sunny skies. Significant cool down and
a chance of showers beginning Tuesday.

&&

.Discussion...
Generally cooler temperatures this morning from light winds and
mostly clear skies overnight, along with a Delta breeze. A weak
upper level trough moves through this afternoon with little
affect, except that high temperatures will be slightly cooler this
afternoon than we saw yesterday. No update is necessary. Ridging
rebounds for the weekend with a slight warmup and continued dry,
sunny weather. Main issue for the weekend is increasing northerly
winds Saturday night through Sunday. This coupled with low
humidity and dry fuels could bring critical fire conditions to the
western side of the Sacramento Valley and adjacent foothills.
There is some potential for increased fire weather issues for
portions of the southern Cascades/north Sierra. EK

.Previous Discussion...
Weak upper trough has resulted in increased onshore flow with
delta breeze picking up last evening and continuing moderately
strong overnight. Flow however is expected to decrease through the
morning. Fort Ord profiler showing little change in marine layer
with depth continuing around 1 k ft. Upper trough moves through
today but will have little additional impact as high temperatures
continue above normal with mid to upper 80s in the Central Valley
and upper 60s to lower 80s for the mountains and foothills.

Upper ridging in EPAC partially builds inland behind upper trough
later tonight into Saturday. Meanwhile, surface high pressure
begins to build through the PacNW into the Great Basin. As a
result some locally gusty northerly wind possible in Shasta
county Saturday. AMS undergoes some warming tomorrow with
increased subsidence.

As surface high pressure continues to build inland, the N-S low
level pressure gradient strengthens over Interior NorCal Saturday
night into Sunday leading to some breezy north to east wind. This
looks to continue into Monday morning before gradient weakens. Dry
conditions combined with increased wind will elevate the fire
potential. Above normal temperatures continue Sunday into Monday
as upper ridge axis moves through and deep low pressure, currently
in the GOA, approaches the West Coast.

GFS/EC similar in moving associated frontal system to the NW Cal
coast around 12z Tue then swinging it down across Interior NorCal
Tue into Tue night. Models showing some precip with the front,
mainly over the mountains and in the Central Valley north of I-80.
QPF looks light as GFS/GEFS IVT weakens as front moves thru, and
NAEFS ensemble only showing about 1.5 standard deviations above
normal for PWs with the baroclinic zone. Associated upper trough
follows the front late Tuesday into Wednesday for a continued
threat of showers, again mainly over the mountains, and in the
Northern Sacramento Valley. System ushers in significantly cooler
AMS with highs Tue/Wed expected in the lower to mid 70s with 50s to
60s for the mountains and foothills. Model depicted instability
looks weak attm so will keep a mention of thunderstorms out of the
forecast for now. Some light snow possible over the higher
terrain late Tuesday into Wednesday but any accumulations expected
to be light.

Oper GFS showing weak ridging following Thursday. EC/GEM keep
more southwesterly flow aloft with weak embedded vort maxes to
suggest a continued slight threat of showers over the northern
third of the forecast area. Slight rebound in temps Thursday but
highs continuing below normal.

&&

.Extended Discussion (Tuesday through Friday)

Extended models are coming into better agreement on a weather
system moving into the Pacific Northwest and impacting northen
California. Therefore, confidence in significant weather change
continue to increase beginning Tuesday extending through Thursday. A
return to normal or below temperatures during the period and a
chance of rain especially north looks good. At this time not looking
like a high impact event Tuesday through Thursday, but certainly
news worthy as it finally may cool us down. There are still some
timing and strength differences in the models, but overall a
cooler and return to precipitation looks good for the central and
Northern Sacramento valley and surrounding mountains.

&&

.Aviation...

VFR conditions next 24 hours under upper level high pressure
ridge. Winds generally below 10 knots except westerly 10 to 20
knots through the delta. Areas of smoke near Sierra fires.
