.KEY MESSAGES...

1. The warming temperatures will continue through late this
week, becoming triple digits in the Valley by Tuesday.

2. Hot and dry conditions next week will create increased fire
risk across the region.

3. Practice safety around lakes, rivers, and streams, as water
is still running cold.

.DISCUSSION...
After zonal flow being the dominate pattern today, ridging will
start to strengthen tomorrow into Wednesday as an area of high
pressure moves in from the southeast into Central California.
This will result in a warming trend that will have Valley highs
back in triple digits by Tuesday through at least Thursday. This
pattern will also dry out the region, leading to 15-20% RH`s in
the Valley and back into the single digits for the Mojave
Desert. This along with the hot temperatures will lead to
increased fire risk for much of the region.

Several consecutive models runs show increasing confidence of a
trough moving through the west coast by Friday, leading to
another slight cooldown for our CWA through the next weekend.
Highs for the Valley from Friday through next weekend show
temperatures in the low 90`s with the northern portion dipping
below 90 degrees on Saturday. This would be about 3 to 5 degrees
below normal for this time of year. That same day, a marine
push from the north may occur, leading to slightly improved
afternoon RH`s for much of the region. Long term models another
warm up starting by next Monday into the beginning of July.
