Tupman, CA

Version 3.4
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.

235 pm pdt Thu may 24 2018

Synopsis A low pressure system moving inland across the
region will bring showers and thunderstorms over the sierra
nevada through the holiday weekend. Best chances will be tonight
into Friday, when showers with afternoon and evening thunderstorms
will be possible in the san joaquin valley. Otherwise, mainly
seasonal to below average temperatures with occasional breezy to
gusty conditions are expected through Saturday. Afterward, a
drying and warming trend will begin by memorial day.

Discussion So far today, latest satellite images show cumulus
cloud buildups over the sierra nevada, while isolated thunderstorm
activity has developed well to the north of yosemite, or just
south of lake tahoe. Showers and thunderstorms will be possible
later this afternoon into the evening over the sierra. However,
additional showers will spread into the region late tonight into
Friday as a relatively cold upper-level low moves inland around
the sf bay area and southeastward over the sj valley. Best
instability will occur during Friday afternoon and evening with
the passage of the low pressure system and associated trough over
central california, so the possibility of isolated thunderstorms
could occur in quite a few locations in our forecast area, even
the southern san joaquin valley. This low will be cold enough for
snow in the sierra nevada high country, as well as well below
average temperatures elsewhere. A winter weather advisory was
posted earlier today due to the possibility of several inches of
snow along the sierra nevada crest, especially in yosemite np.

Otherwise, snow accumulations of one to three inches are possible
along the crest to the south towards kings canyon np. So, a very
active weather pattern remains on track for Friday into Saturday.

A temperature roller coaster is in store through next week.

Compared to mainly seasonal averages for today, highs will be much
cooler, or well below average, on Friday as the low pressure
system approaches and brings unsettled weather. Temperatures on
Friday could fall as much as 15 to 20 degrees in terms of daytime
highs from today. However, a significant warming trend will occur
each day behind the trough of low pressure, especially on Sunday
through Tuesday. High temperatures on memorial day will likely
return to at least several degrees above average as high pressure
ridging develops. The change in daytime highs from Friday to
memorial could translate to as much as 20 to 25 degrees in many
locations, including in the central valley.

By Wednesday and Thursday another low pressure system moving over
the pacific northwest could at least bring a return to seasonal
temperatures. The associated trough may dig far enough south for
another chance for convection over the sierra nevada, including
isolated thunderstorms. One caveat is due to some forecast model
disagreement in terms of timing of this next low pressure system
and amplitude of the trough.

Aviation
Expect showers and isolated thunderstorms over the higher
elevations of the southern sierra nevada through 03z Friday.

However, mountain obscurations over the sierra nevada will
continue overnight tonight, and scattered showers will spread
inland overnight tonight, or after 06z Friday, due to an
approaching low pressure system. Numerous rain and snow showers
are expected over the sierra nevada after 12z Friday with
isolated to scattered thunderstorms developing after 18z Friday.

In addition, showers and isolated thunderstorms are possible over
the san joaquin valley and sierra nevada foothills during 18z fri
thru 03z sat. Otherwise,VFR conditions will prevail elsewhere
across the central ca interior during the next 24 hours.

Air quality issues
None.

Certainty
The level of certainty for days 1 and 2 is high.

The level of certainty for days 3 through 7 is medium.

Certainty levels include low... Medium... And high. Please visit
