DISCUSSION:
A few showers may form over the interior mountains and deserts of
Los Angeles and Ventura Counties today. Any totals will be under
0.25 inches. The next storm will impact the area late Wednesday
night through Friday.
Fairly confident that San Luis Obispo and Santa Barbara Counties
will have lighter totals (0.25 to 0.50 inches common, except 0.5 to
1.0 inches in some favored mountains) and rates (0.10 to 0.25 inches
per hour). For Los Angeles and Ventura Counties, the most likely
outcome is for moderate amounts (0.5 to 1.0 inches except 1 to 2
inches in favored mountains and hills) and rates (0.20 to 0.33
inches per hour). The convective and dynamic nature of the proximity
of the low brings the potential of double those amounts. Snow levels
will be above 6,000 feet for most of the precipitation, but will
drop to as low at 5,000 feet on Friday. There is a slight chance of
thunderstorms Thursday Night through Friday. Snow amounts of 3 to 6
inches is the most likely outcome for elevations above 6000 or 6500
feet.
Dry weather will likely follow this weekend through at least most of
next week.
