AREA FORECAST DISCUSSION...UPDATE
NATIONAL WEATHER SERVICE SAN DIEGO CA
330 PM PDT SUN SEP 14 2014

.SYNOPSIS...
HOT WEATHER WILL CONTINUE THROUGH TUESDAY UNDER HIGH PRESSURE ALOFT
AND WEAK ONSHORE FLOW. SOME MOISTURE AND INSTABILITY WILL RESULT IN
A SLIGHT CHANCE OF AFTERNOON AND EARLY EVENING THUNDERSTORMS THROUGH
TUESDAY...MAINLY OVER THE MOUNTAINS. MOISTURE ASSOCIATED WITH
HURRICANE ODILE WILL BRING MORE WIDESPREAD SHOWERS AND THUNDERSTORMS
WEDNESDAY AND THURSDAY ALONG WITH COOLER BUT MORE HUMID WEATHER. A
FEW THUNDERSTORMS COULD LINGER INTO FRIDAY.

&&

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

CONVECTIVE TEMPERATURES HAVE BEEN EXCEEDED OVER THE INLAND EMPIRE SO
ISOLATED THUNDERSTORMS HAVE DEVELOPED. STRONG WIND GUSTS ARE
POSSIBLE.

THERE WAS A LOT OF CUMULUS OVER THE MOUNTAINS...WITH A FEW SHOWERS
DEVELOPING. NO LIGHTNING STRIKES HAVE YET BEEN RECORDED IN SOUTHERN
CALIFORNIA...BUT AN ISOLATED LIGHTNING STRIKE COULD OCCUR THROUGH
EARLY THIS EVENING. IT WAS ANOTHER HOT DAY TODAY WITH 107 IN SAN
PASQUAL VALLEY AND 106 IN ELSINORE SO FAR...AND 109 IN PALM DESERT.

 NOT MUCH CHANGE WILL OCCUR THROUGH TUE WITH MODERATE AMOUNTS OF
MID-LEVEL MOISTURE...MAINLY BETWEEN 700 AND 500 MB AND SOME
INSTABILITY TO BRING SLIGHT CHANCES OF THUNDERSTORMS TO THE
MOUNTAINS EACH AFTERNOON...AND LOCALLY OVER THE ADJACENT DESERTS.
NOT MUCH CHANGE WILL OCCUR WITH HIGH TEMPS MONDAY AS THE ATMOSPHERIC
PROFILE WILL BE SIMILAR OR JUST VERY SLIGHTLY COOLING...THEN THERE
WILL BE A COUPLE DEGREES OF COOLING AS THE PROFILE COOLS SLIGHTLY
TUESDAY. THE MARINE LAYER STRATUS WILL MOSTLY BE ABSENT DUE TO THE
WEAK ONSHORE FLOW AND NEAR-SURFACE BASED INVERSION.

THE ELEPHANT IN THE ROOM IS HURRICANE ODILE WHICH IS NOW AT 21N/109W
AND MOVING TO THE NORTHWEST ABOUT 14 MPH. PEAK SUSTAINED WINDS ARE
AROUND 125 MPH. THE OFFICIAL NHC TRACK FORECAST IS A BIT TO THE
RIGHT VERSUS BEFORE...WITH A TRACK RATHER CLOSE TO THE BAJA PACIFIC
COAST. LARGE MOISTURE INCREASES WILL STILL OCCUR WED WITH PRECIP
WATER MOSTLY BETWEEN ABOUT 1.75 AND 2.00 INCHES AT THE COAST AND IN
THE DESERTS...INCLUDING MOISTENING OF THE LAYERS BELOW 700
MB...THOUGH THIS IS SLIGHTLY LESS THAN WHAT WAS INDICATED SATURDAY.
THIS WILL BE STILL IDEAL FOR WIDESPREAD SHOWERS AND
THUNDERSTORMS...ESPECIALLY IF WE MANAGE TO AVOID TOO MANY DEBRIS
CLOUDS AS THE PROFILES INDICATE RELATIVELY DRY AIR ABOVE 500 MB.
DYNAMICS WILL DETERMINE WHETHER OR NOT ANY COASTAL THUNDERSTORMS
WILL OCCUR...BUT SOME THUNDERSTORMS COULD FORM IN THE
VALLEYS...INCLUDING THE ELSINORE CONVERGENCE ZONE. FLASH FLOODING
WILL BE POSSIBLE WED AND ALSO THU. THE MODELS HAVE THE REMNANT LOW
MOVING INLAND ACROSS NORTHERN BAJA AND INTO SW ARIZONA LATE
THU/FRI...BUT WITH A LIKELY CLOSED LOW FORMING OFF THE SOUTHERN
CALIFORNIA COAST...SOME OF THE MOISTURE COULD BE SHIFTED WEST FRI
AND OVER THE WEEKEND. WE HAVE SLIGHT CHANCES OF THUNDERSTORMS IN THE
MTNS/DESERTS FOR FRIDAY...AND DEPENDING ON MODEL SOLUTIONS IN THE
NEXT DAY OR SO...WE MAY NEED TO ADD SLIGHT CHANCES OVER THE WEEKEND.
