AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN DIEGO CA
330 AM PST THU MAR 5 2015

.SYNOPSIS...
FAIR SKIES AND DRY WEATHER WILL PREVAIL THROUGH TUESDAY.
TEMPERATURES WILL CONTINUE TO TREND UP OVER SOUTHWEST CALIFORNIA
AS A RIDGE BUILDS ALONG THE COAST AND OFFSHORE WINDS DEVELOP.
AFTERNOON HIGH TEMPERATURES WILL PEAK AT 10-16 DEGREES ABOVE
NORMAL OVER THE WEEKEND. OFFSHORE WINDS WILL PEAK FRIDAY MORNING
WITH GUSTS AROUND 50 MPH FOR THE WINDIER MOUNTAIN AND VALLEY
LOCATIONS.

&&

.DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO
COUNTIES...

WHILE A HUGE SWATH OF THE SOUTHERN AND EASTERN UNITED STATES WILL
BE DIGGING OUT FROM HEAVY SNOWFALL THIS MORNING...TEMPERATURES
WILL BE ON THE RISE ACROSS SOUTHERN CALIFORNIA. WARM WEATHER WILL
BE THE STORY THROUGH THE END OF THE WEEK WITH TEMPERATURES TOPPING
OUT FRIDAY THROUGH SUNDAY BY AS MUCH AS 17 DEGREES ABOVE NORMAL.
THE CAUSE FOR ALL OF THIS WARM WEATHER WILL BE A STRENGTHENING
UPPER LEVEL HIGH PRESSURE CELL ACROSS THE EASTERN PACIFIC AND
NORTHERN CALIFORNIA...WHICH WILL PERSIST THROUGH THE UPCOMING
WEEKEND.

OFFSHORE FLOW WILL DRIVE GUSTY WINDS THROUGH THE WESTERN MOUNTAIN
SLOPES DOWN INTO THE VALLEYS WITH THE STRONGEST WINDS LIKELY FROM
LATE TONIGHT THROUGH FRIDAY. PEAK WINDS OF 50-55 MPH WILL BE
LIKELY BUT THE STRONGEST WINDS WILL OCCUR IN REMOTE...HILLY
TERRAIN WITH MINIMAL IMPACT...THEREFORE WILL HOLD OFF ON ANY WIND
ADVISORIES FOR NOW. ALTHOUGH OFFSHORE FLOW WILL BECOME LIGHTER
AFTER FRIDAY...VERY WARM WEATHER WILL PERSIST INTO SUNDAY DUE TO
THE RESIDUAL WARM LOW LEVEL AIRMASS.

A SIGNIFICANT PATTERN CHANGE IS STILL LIKELY FOR MID NEXT
WEEK...ALTHOUGH THE DETAILS ARE A BIT FOGGY AT THIS MOMENT. WE ARE
CONTINUING TO MENTION A SLIGHT CHANCE FOR PRECIPITATION ON
WEDNESDAY...ALTHOUGH THE FORECASTER CONFIDENCE IS LOW AT THIS
POINT DUE TO SO MUCH RUN TO RUN VARIANCE IN THE MODELS. A WETTER
PATTERN IS STILL POSSIBLE FOR LATE NEXT WEEK...BEYOND OUR
OPERATIONAL FORECAST PERIOD....SO KEEP AN EYE ON OUR LATER
FORECASTS FOR MORE DETAILS!
