Area Forecast Discussion

.SYNOPSIS...
Near average to below average temperatures persist for the
remainder of this weekend into next week. Afternoon thunderstorms
possible in the higher elevations of the Sierra Nevada.

&&

.DISCUSSION...
Seasonal temperatures will continue until late next week with
cool, mild overnight lows in the lower elevations. Expect highs
mainly in the 80`s in those lower elevation locations, including
the Central Valley, lower Sierra foothills, and the Kern County
desert and even cooler in the mountains. A daily threat of
thunderstorms will persist over the higher elevations of the
Sierra Nevada through next week. In addition, models project a
persistent trough pattern along or off the coast through the next
several days. Overnight low temperatures will be chilly in higher
elevations, or below freezing at elevations mainly above 7,000
feet. Unfortunately, high flows along rivers will continue for
quite some time, and plenty of snowpack remains in the higher
elevations, or generally above 8,000 feet.

The probability of a high temperature of 90 degrees in the Central
Valley remains below 20 percent until Wednesday of next week,
based. For today and Sunday, there is a moderate chance (roughly
40 to 60 percent) that highs will reach into the upper 80`s today,
as both ensemble and high resolution deterministic guidance
depict a weak upper-level ridge of high pressure that passes over
Central CA. A warming trend is in store beginning Thursday of next
week into the following Saturday, just in time for June. Based on
latest probabilities, a high of at least 90 degrees has about a
20 to 40 percent of occurrence for this period, at least in the
San Joaquin Valley.

For everyone`s safety, please stay out of the rivers, as they are
dangerously cold and fast!

.AVIATION...
VFR conditions will prevail at all of the terminal aerodrome sites
through at least the next 24 hours, except for possible MVFR
visibility at times due to haze towards BFL. MVFR or lower
conditions are likely in and near any thunderstorm in the Sierra
Nevada this afternoon and this evening.

.AIR QUALITY ISSUES...
None.
