Area forecast discussion
National Weather Service Sacramento California
130 PM PDT Thu Aug 22 2019
Above average temperatures are expected into next week. Dry
weather pattern continues.
Dissipating cirrus has left clear skies and another day of hot
temperatures across the interior of norcal. A trough currently
located across central Montana will move east while high pressure
over the Pacific will continue to move over the area. Highs today
will be slightly warmer than yesterday with most valley locations
in the upper 90s and low 100s. The high continues to expand into
norcal through the weekend keeping the forecast dry with above
average temperatures. Even with these hot afternoon highs, most
locations will experience a slight break from the heat overnight
with lows falling into the 60s early morning.
Extended discussion (monday through thursday)...
The heat continues early to mid next week as Pacific high pressure
continues to influence the area. Monday and Tuesday look to be
the hottest days of the week as the high centers itself across
northern California. Highs in the valley Monday will reach back
into the 100s with the northern portion of the Sacramento Valley
seeing temperatures up to 108 degrees. Mountain highs look to be
in the low 80s. Temperatures Tuesday will be similar to those of
Monday. Low temperatures, especially in the northern SAC valley
may only reach back into the low 70s which could pose concerns for
those sensitive to heat.
The ridge looks to finally break down near the end of the period as
a shortwave moves northeast towards the norcal coast. Have continued
a dry forecast as the best moisture and dynamics look to be north
and east of the area, but this will be something to watch for future
updates. Temperatures do look to cool back to average values by
Thursday with this feature.
VFR conditions the next 24 hours. Breezy northerly winds gusting
to 20 knots mainly at the northern terminals will diminish to
under 10 knots early this evening.
