.DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...

COUNTIES...
.Evening Update...
The main frontal band has moved through the region this evening.
This brought a line of heavier rain for the coasts and valleys.
Big winners closer to the coast include National City with 0.75"
of rain and Point Loma & Santee just above 0.50". Winds have been
gusting near 40-55 MPH across parts of the mountains and desert
slopes this evening. These winds will continue to weaken
into the early morning hours. The trough overhead will continue
to push eastward where showers will become more isolated overnight
into early Friday morning.
Post-frontal clouds will bring intervals of sunshine west of the
mountains with better chances for sun across the deserts. A chilly
night is in store for the region, where there is a 50-50 chance
for the Big Bear Lake region to dip to 10 degrees tonight.
Confidence is moderate to see areas of IE and inland San Diego
valleys dip below freezing tonight as well by Saturday morning.
Rain/snow lovers, we hope you enjoyed. If you`re ready to get back
to the sunshine and warmer weather, this weekend is just for you!
.Previous Discussion (145 PM Thursday)...
As skies begin to clear late tonight, cold air pooling could
produce some frost in portions of the inland valleys and coastal
areas early Friday morning.
Fair and dry, but cool weather starts Friday, with some variable
high clouds. Weak offshore flow over the weekend will boost the
drying and warming trend as high pressure aloft amplifies a
little. Temperatures in the 60s Saturday will be followed by lots
of 70s Sunday at lower elevations. A weak and stationary ridge
appears to be taking shape over California next week. Current
guidance shows that high pressure aloft is likely to control our
weather through the middle of next week. This could allow a return
of marine layer coastal low clouds during the nights and mornings.
Monday and Tuesday will likely be the warmest days, with temps in
the upper 70s at low elevations west of the mtns and in the low to
mid 80s in the lower deserts. Some ensemble members are
indicating chances for precipitation next Wednesday but the
majority remain dry.
