.DISCUSSION...
High pressure ridge now dominating the area as a heat-wave
starts across Central California. Confidence in triple digit
temperatures is high as ensemble consensus all lean in the
direction of a three day heat-wave. While Probability of
Exceedance (PoE) of reaching 105 degrees remains below 50%,
except for a few areas, PoE of 100 degrees has widespread max
percentages above 90% through Monday. These high PoE percentages
increased confidence in the Heat Advisory currently in effect
for the San Joaquin Valley and adjacent foothills. Little change
is expected through Tuesday ahead of a disturbance that will
begin a cooling trend by Midweek.

Ensemble temperature analysis has been very consistent with the
onset of the current heat-wave. Heat Advisory has been issued
for a three (to possibly four) day stretch as max temperatures
range from 100 to 105 degrees. The ridge pattern generating the
heat-wave is also responsible for keeping winds across the
region light. Except for local wind favored areas that become
breezy during the afternoon period, will expect winds to remain
light and diurnally driven.

Until the ridge pattern breaks down due to a passing Pacific
Northwest disturbance, the region will be dominated by a
southwesterly wind flow. That flow will push monsoonal moisture
east and avoid Central California. Without a southeasterly wind,
the lack of moisture will keep the region dry. Long range
ensemble analysis shows very good agreement in keep Southern
California dry through day seven (next Saturday).
