Dry and warmer weather this week as high pressure rebuilds. Breezy
to locally windy northeast to east winds over the Sierra Nevada
overnight, decreasing Thursday.
Warm days and cool nights ahead for the next several days. A ridge
of high pressure will continue to build over the region into
Saturday warming temperatures a little each day. Upper 80s to
lower 90`s for valley locations on Thursday warming into the 90s
for Friday and Saturday. At night temperatures will cool into the
50s with a few of the cooler spots dipping into the upper 40s.
Mountain valley`s will cool into the 20s and 30s. Lighter winds
with clear skies and a dry air mass tonight will allow for cooler
temperatures overnight. Temperatures will peak Friday and Saturday
with only slight daytime cooling for Sunday expected.
Winds in the valley tonight will generally be light for most areas
while in the Sierra Nevada local gusty canyon winds to 35 mph may
occur. The offshore gradient will get lighter each day along with
the winds into the weekend.
.Extended Discussion (Sunday through Wednesday)
Medium range models similar in showing strong upper level ridging
over Interior NorCal Sunday gradually weakening through the
extended forecast period. Also, weak upper low forecast to develop
early next week and slowly approach the Coast. Result will be dry
weather with high temperatures initially about 10 degrees above
normal on Sunday, returning to near normal by the middle of next
week. EPAC surface high pressure extends through the PacNW into
the Great Basin with thermal troughing resulting in continued
locally breezy North to East wind Sunday into Monday morning.
