DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO
COUNTIES...
THIS EVENING, TEMPERATURES THIS AFTERNOON WERE UP TO 15
DEGREES HIGHER THAN YESTERDAY AFTERNOON AND RANGE FROM SLIGHTLY
BELOW TO SLIGHTLY ABOVE SEASONAL AVERAGES. WIDESPREAD HIGH CLOUDS
IN A RIDGE OF HIGH PRESSURE WILL CONTINUE TO COVER THE REGION
TONIGHT, INHIBITING RADIATION COOLING SOMEWHAT SO THAT OVERNIGHT
LOWS WILL NOT BE AS COLD AS LAST NIGHT.
FROM PREVIOUS DISCUSSION...
WITH HIGHER PRESSURE CONTINUING TO BUILD IN, DAYTIME TEMPERATURES
WILL BE WARMER TOMORROW. THE INCREASED SUBSIDENCE OVER THE REGION
WILL ALSO ALLOW FOR THE BASES OF THE MARINE LAYER TO LOWER AND
THERE COULD BE SOME PATCHY AREAS OF FOG ALONG THE EXTREME COASTAL
AREAS TOMORROW NIGHT, AS WELL AS OUT OVER THE INNER WATERS. THERE
WILL BE A COOLING TREND BEGINNING EARLY IN THE WEEK, WITH AN
INCREASE IN ONSHORE FLOW. DUE TO THIS, THE CHANCE OF PATCHY FOG
WILL ALSO INCREASE, ESPECIALLY WITHIN SOME OF THE INLAND VALLEYS,
ON MONDAY NIGHT THROUGH TUESDAY MORNING.
THROUGH NEXT WEEKEND...PASSING MAJOR SHORTWAVE TROUGHS LOOK TO
REMAIN FAR ENOUGH TO THE NORTH THAT THERE WILL BE VERY LITTLE
IMPACT TO THE REGION, OTHER THAN SOME DAYS OF INCREASED WINDS AND
THICKENING OF THE MARINE LAYER WITH POSSIBLE AREAS OF DRIZZLE BY
LATER IN THE WEEK. OTHERWISE, HIGH PRESSURE WILL REMAIN IN CONTROL
WITH TRANQUIL WEATHER EXPECTED THROUGH NEXT WEEKEND.
