DISCUSSION:

Another impulse will move over the area today. It will be colder and
more unstable. It will bring showery precipitation and slight chc of
TSTMs. Additional storm totals today will likely range from 0.25 to
an 1.00 inch for most areas, with 1 to 1.5 locally 2 inches in the
mountains, foothills, and under thunderstorms. Peak rain rates will
generally range between 0.20 and 0.50 inches per hour, with local
rates up to 1.00 inches per hour with heavier showers and
thunderstorms. Snow levels will lower to between 6000 and 7000 feet
on this afternoon and evening, with 2 to 4 inch accumulations
possible at 7000 feet and above.

Showers and a slgt chc of TSTMs will continue during the early
evening but will rapidly decrease from the west to east late in the
evening. A small chc of showers/TSTMs will continue over LA county
for a few hours past midnight as the impulse pushed out to the east.

For Monday and Tuesday, there is a chance of light showers. Dry
weather is expected Wednesday through next weekend.
