Area Forecast Discussion
National Weather Service Sacramento CA
200 AM PDT Wed Jul 24 2024

.SYNOPSIS...
Hot again today then cooling trend Thursday into the weekend.
Locally elevated fire weather concerns today and Thursday with
areas of afternoon to evening gusty wind and lower humidity.
Threat of afternoon thunderstorms today near Sierra Nevada crest
eastward.

&&

.Discussion...
597 DM upper high centered over the Great Basin will continue hot
weather across interior NorCal today with widespread moderate to
major heat risk. High temperatures expected to be near or a few
degrees lower than Tuesday. Delta breeze looks to be slightly
stronger today, but cooling effect is limited as marine layer
remains shallow under strong subsidence. Upvalley pressure
gradient increases today with stronger afternoon to evening
southerly wind over the interior. This could result in a short
period of elevated fire weather conditions today and Thursday.
Slight chance of afternoon showers or thunderstorms over higher
elevations of our Sierra Nevada zone, however main activity
expected to be crest eastward similar to the last several days.

Cooling trend Thursday into Friday as heights/thicknesses lower
in response to deep short wave trough moving through the PacNW and
cutoff low progged through the CWA Friday afternoon into night.
Synoptic cooling with deepening marine layer and increased onshore
flow expected. Enhanced midlevel SWly flow should keep any Sierra
Nevada deep moist convection crest eastward. Locally gusty wind
continues to be possible during the afternoons as humidity trends
up into Friday.

Broad upper troughing remains along the West Coast into the
weekend. NBM advertising below normal temperatures Saturday with
mid 80s to lower 90s for the Central Valley and upper 60s to lower
80s for mountains and foothills.

&&


.EXTENDED DISCUSSION (Sunday THROUGH Wednesday)...
Long wave troughing remains along the West Coast through the
weekend keeping high temperatures below normal. Models diverge
with solutions early next week as cluster analysis varying from
unseasonably deep short wave trough moving into the PacNW Tuesday
to strong Desert SW high expanding back northwestward over NorCal
through midweek. NBM favoring a gradual warming trend with high
temperatures returning to near or slight above normal Tuesday into
Wednesday.

&&

.AVIATION...
VFR conditions over interior NorCal next 24 hrs. In Central Vly,
areas Sly sfc wind up to 20 kts possible btwn 20z-05z. Vcnty of
Delta, SWly sfc wind 15-25 kts. Isolated shra/tsra possible vcnty
of Sierra Nevada crest btwn 20z-03z.

.STO WATCHES/WARNINGS/ADVISORIES...
