.DISCUSSION...
Temperatures continued to climb this afternoon and latest models
continue to rise through the week thanks to a ridge of high
pressure over the area. However, ensembles show large amounts
of moisture to advect into Northern California despite the ridge
budging slightly south. Models have continued to back off on
precipitation amounts as there is a 5 to 15 percent chance of
even a tenth of an inch of rain in 24 hours ending 4 am
Wednesday. Merced has the highest probabilities in the Valley
with a 40 percent chance of a tenth of an inch of rain ending 4
am Wednesday. The foothills and Sierra Nevada also see a
decrease in precipitation with the Yosemite Area seeing a peak
probability of 15 to 30 percent chance of an inch of rain in 24
hours ending 4 am Wednesday. There currently is a marginal risk
of Excessive Rainfall on Tuesday because of the rain amounts.
However, the foothills of Mariposa and Madera Counties see a 40
to 65 percent chance of a quarter of an inch of rain which is
lower than before with the rest of the foothills at 15 percent
chance or less for a quarter of an inch.

The ridge will restrengthen Thursday into the weekend as the
potential for 70s continues from Tuesday. Wednesday has a 65 to
80 percent chance of highs of at least 70 before dropping off on
Thursday and Friday to 45 to 70 percent. The probabilities
rebound on Saturday to 70 to 80 percent but drop off again
slightly next Sunday to 55 to 75 percent. This favors the CPC
outlooks which shows a 70 to 80 percent chance of above average
temperatures in both the 6-10 and 8-14 day outlooks. There also
is a 33 to 40 percent chance of below average precipitation in
both the 6-10 and 8-14 day outlooks.
