.KEY MESSAGES...
1. Moderate Heat Risk will be present for much of the lower
elevations today and Wednesday.

2. There is a 5 to 10 percent chance for thunderstorms in the Sierra
Nevada this afternoon and evening. Near-zero chances for the
remainder of the week.

3. Drier air will cause minimum relative humidity to fall
between 15 and 20 percent for much of the San Joaquin Valley
through the forecast period.

4. A minor cooling trend arrives later this week, then expect
steady and seasonably warm temperatures into the weekend.

.DISCUSSION...
High pressure building over central California today will cause
temperatures to warm up to ten degrees above season averages for
this date. For the San Joaquin Valley south of Fresno, there is
a 40 to 80 percent chance for maximum temperatures to reach 100
degrees or more this afternoon. A small amount moisture due to
southwest flow in the mid levels may result in thunderstorms
over the crests of the Sierra Nevada later today, though chances
are only at 5 to 10 percent.

The central area of high pressure is expected to move further
off the Pacific coast overnight, setting up a zonal flow pattern
and subsequent cooling trend through Friday. For the weekend,
the ridge of high pressure is favorable to slide over the Four
Corners region, allowing a trough to pass through the Pacific
Northwest and Northern California regions which will cause a
stronger decrease in temperatures to near normal.

With the upcoming pattern, minimum relative humidity is
anticipated to decrease as well, with widespread 15 to 20
percent across the San Joaquin Valley through into next week.
These conditions paired with cured fine fuels across the area
will continue the threat for grass fire development. Minimum RH
values will also lower under 15 percent in the Sierra Nevada
closer to the weekend. Drying 100 hour fuels will increase the
risk for fire development in these areas, though 1000 hour fuels
still remain near average.
