.KEY MESSAGES...

1. There is a 10 to 15 percent chance for thunderstorms in the
Sierra Nevada this afternoon and evening.

2. Triple digit temperatures are expected to return later this
week.

3. Low minimum RH`s are expected to remain in the Valley and
deserts through the next week.

&&

.DISCUSSION...
An upper level trough is over the Southwest currently, with
temperatures expected to be below normal again today, and a
slight chance for thunderstorms in the Sierra Nevada this
afternoon. As the trough weakens and moves east, a ridge will
build into the region, causing temperatures to gradually
increase throughout the week, with temperatures returning to the
triple digit range on Friday. These temperatures will cause a
moderate heat risk for the Valley and Desert regions.

Throughout this week relative humidity is expected to remain
steady, with 15 to 20% in the Valley and single digits in the
Deserts. With low winds, fire risk remains minor.
