What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Synopsis
Hot and dry weather this week.

Discussion
Anti-cyclonic flow beginning to take hold as the large upper low
that brought the cool weather over the weekend has now drifted
into montana. Skies are mostly clear across the region early this
morning and current temperatures are mostly milder compared to 24
hours ago and generally range from the 40s in the mountain valleys
to the upper 50s to upper 60s across the central valley (except
70s across portions of the northern sacramento valley.

Upper ridging progged to build thru mid-week with dry weather and
slightly above average temperatures. Light to moderate delta
breeze expected to continue tempering the heat in the delta and
sacramento region. Short-wave skirts far northern ca late
Wednesday, but appears deeper convection will occur north of the
forecast area (or ca border and north into the pacnw).

The hottest weather so far this season is forecast to begin Friday
as high pressure strengthens and surface flow transitions to
northerly. Highs through the central valley on Friday are expected
to range from 100-105.

.Extended discussion (Saturday through Tuesday)
high pressure ridging will bring hot weather to the area this
weekend, peaking on Saturday. High temperatures for Saturday are
forecast to be 12 to 17 degrees above normal, with 102-105 across
the central valley, 93-103 in the foothills, 73-93 in the
mountains. This will bring the potential for moderate to high heat
risk, even for the general population in a significant portion of
the central valley and the delta and into the foothills.

Sacramento is currently forecast to reach 105, which is one degree
shy of the record of 106, set in 1988. Redding is also forecast
to reach 105, which is well short of the record of 111, set in
2006.

Northerly winds and low humidity levels will increase fire danger
over the weekend, especially on Saturday.

Sunday may be a little less hot as the ridge axis shifts eastward
and flow shifts to more southwesterly. This will be felt most in
the delta and adjacent areas, as a delta breeze brings some
cooling later in the day and overnight. Monday is expected to see
more cooling but continued above normal temperatures, with valley
highs generally in the 90s. Tuesday should be cooler yet, with
temperatures closer to normal. So, the good news is this heat
event will be relatively short. Ek

Aviation
Vfr conditions continue over the next 24 hours. Dry weather is
expected. Winds at TAF sites will generally be less than 10kt. Ek

Sto watches warnings advisories None.
