AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SACRAMENTO CA
330 AM PDT MON AUG 31 2015
Dry with mostly below normal temperatures this week.
Clear skies across the interior of NorCal early this morning.
Temperatures are running pretty similar to those of 24 hours ago.
Expect a little warmer temperatures across the region today and
Tuesday as the trough over the region weakens and onshore flow
Cooler temperatures and stronger onshore flow are expected to
return by mid-week as additional short-wave energy rotating around
the big upper low over British Columbia deepens the trough along
the west coast.
Valley highs in the lower to mid 90s today and Tuesday will cool
back into the 80s for Thursday and Friday.
.Extended Discussion (Friday through Monday)...
Large scale pattern will continue to feature upper level trough
and associated low. This feature will drop SE across the region on
Friday into the weekend. Dry forecast still on track thru the
weekend as moisture remains limited and any precipitation progged
to remain north of the local area at this point. Not out of the
question that a few showers could skirt across far northern
portions of the state Friday into Saturday but model differences
still exist. Temperatures will warm a few degrees from Friday into
the weekend with daytime highs returning to near or slightly above
normal for the beginning of September. CEO
VFR conditions thru the period. Weak onshore flow will continue
with winds at TAF sites generally 10 kts or less. Gusts to 20 kts
possible across Delta region later this evening into tonight.
