245 PM PDT TUE JUL 26 2016

Daytime highs will remain well above normal through Friday with
little relief overnight. Cooler this weekend with isolated
thunderstorms possible over the higher Sierra.


High pressure centered over the Four Corners area is drifting
westward over the region bringing very hot weather through the
rest of the work week. At 2 pm, it was already 108 at Redding,
105 at Red Bluff, and 102 at downtown Sacramento. Redding could
tie or break the record of 110 set at the airport (city record of
113). With a much weaker Delta breeze, there will be limited
cooling tonight. Wednesday/Thursday are expected to see peak
temperatures with little change Friday. No real cooling is
expected until the weekend.

Some smoke and haze continues to stream from the Soberanes Fire
in Monterey County area northeastward over the area, from around
I80 southward. Some of this smoke may shift further south (per
HRRR experimental model) through tonight, and then return again
early Wednesday.

Some monsoonal moisture will be drawn up by the high pressure.
This could bring some isolated showers/thunderstorms to the higher Sierra
south of Highway 50 in the afternoon/early evening on Thursday and
again on Friday. EK



Upper level trough swings through the Pacific Northwest this
weekend giving us a little more onshore flow. Temperatures will
begin to cool to around normal for this time of year (mid to upper
90s) for much of the Valley by later part of the weekend.

Models still indicating some monsoonal moisture reaching portions
of the Sierra Saturday and Sunday. A few isolated thunderstorms
are possible in the Sierra south of Hwy 50 during this time, but
this pattern typically results in convection on the eastern side
of the crest. 



VFR conditions across all TAF sites for the next 24 hours. Haze
possible in areas due to smoke from the Soberanes Fire, but smoke
itself will remain elevated. Winds below 10kts with some gusts up
to 20 kts in the Delta region.
