DISCUSSION...
An unseasonably deep trough of low pressure will bring mostly
light rain from the coast to the mountains late tonight into
Friday afternoon. Light, scattered showers are expected Friday
morning mostly west of the mountains. By Friday afternoon,
chances of thunderstorms enter the forecast for the Inland Empire,
San Bernardino mountains, and the High Desert. Rain rates are
expected to be 0.25 to 0.50 inches per hour in thunderstorms. Most
coastal and valley locations should receive 0.10 inch of rain or
less, higher amounts possible where thunderstorms develop in the
Inland Empire. Rainfall totals for the mountains will be variable.
0.10-0.30 inches are expected with higher amounts where
thunderstorms develop.
