.KEY MESSAGES...
1. Temperatures near season averages across the region today
before a gradual warm up into the triple digits later this week.

2. Low RH values 15 to 25 percent will stretch across much of
the San Joaquin Valley and Sierra Nevada with values 5 to 10
percent in the Mojave Desert. RH will decrease over the region
later in the week with warming temperatures.

&&

.DISCUSSION...
High pressure ridge pattern becoming the dominate feature over
the West Coast during the latter half the week. With this, will
expect a continuation of the warming trend as widespread triple
digits will be seen by Thursday and Friday. In addition to the
rise in temperatures, the ridge pattern will allow for monsoonal
moisture to surge northward as a potential for convection will
exist across the Mojave Desert later this week. With little
change in the overall pattern, will expect the duration of the
heat wave to last from near Friday through at least next
Tuesday.

Ensemble Probability of Exceedance (PoE) of reaching 100
degrees starts off below 30% over the next few days. Thursday
marks the transition period at which time the PoE jumps up to a
range between 50% and 90%, with the higher end on the west side
of the San Joaquin Valley along the Interstate-5 corridor. Also,
by Thursday, the Kern Desert maxs out its PoE with values
above 90% for the duration of the period. Friday shows both the
San Joaquin Valley and Kern Desert having probabilities in the
90% and above range. At that point, confidence in widespread
triple digits increases for the start of the next heat wave.
Little change in PoE values observed through the weekend as
triple digits will be here to stay through the early part of
next week.

Ensemble Cluster analysis of Precipitable-Water is showing good
consensus in attempting to push monsoonal moisture northward
toward Central California later this week. While the
southwesterly flow aloft will hinder its surge toward Central
California. Yet, ensemble analysis does show a very slight
chance of development toward Friday and Saturday across the Kern
Desert. Otherwise, dry and hot across Central California with
afternoon wind breezes over the favored locations.
