NWS San Diego, CA wrote its last area forecast discussion before the first event at Jul 20, 1:30 PM PST, 1 hour 20 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SAN DIEGO CA 230 PM PDT WED JUL 20 2005 .SYNOPSIS...STRONG HIGH PRESSURE AND EASTERLY FLOW WILL BRING MORE HEAT AND HUMIDITY TO SOUTHWEST CALIFORNIA FOR THE REMAINDER OF THE WEEK. EVEN COASTAL AREAS WILL WARM AS THE MARINE LAYER IS FORCED OFFSHORE. INCREASING MOISTURE FROM MEXICO WILL BRING SCATTERED SHOWERS AND THUNDERSTORMS IN THE MOUNTAINS AND DESERTS FOR THE NEXT FEW DAYS...MAINLY DURING THE AFTERNOONS. SOME OF THESE SHOWERS COULD DRIFT TO THE COAST DUE TO SOUTHEAST FLOW ALOFT TODAY AND THURSDAY. THE THREAT FOR RAIN WILL INCREASE OVER THE WEEKEND AS MOISTURE FROM THE REMAINS OF HURRICANE EMILY MOVE OVER THE REGION. && .DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE... SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO COUNTIES. SATELLITE IMAGERY SHOWS THE CLOUD COVER ASSOCIATED WITH THE SE MONSOONAL FLOW CONTINUING TO MOVE ACROSS SOCAL AND SHOWERS AND POSSIBLE TSTMS ARE BEGINNING TO DEVELOP IN THE UPPER DESERTS. THIS HAS PUSHED THE MARINE LAYER ABOUT 30 MILES OFF THE COAST AND ALLOWED THE COASTAL AREAS TO WARM UP WITH SOME LOCATIONS REACHING THE UPPER 70S TO LOW 80S. THE SEA BREEZE HAS BEGUN BUT IS WEAK AND IS HAVING LITTLE OR NO EFFECT ON COASTAL TEMPERATURES SO FAR. FARTHER INLAND...MOISTURE LEVELS REMAIN HIGH WITH DEWPOINT TEMPS IN THE 60S AND 70S IN THE LOWER DESERTS. THE NAM MODEL SHOWS DEEP MOISTURE AND INSTABILITY OVER THE REGION TODAY AS MOISTURE FROM THE NOCTURNAL MEXICAN CONVECTION IS STEERED OVER THE AREA ON INCREASING SE WINDS ALOFT. AS A RESULT...EXPECT TO SEE INCREASED CONVECTION THIS AFTERNOON AS TEMPS CONTINUE TO CLIMB...PARTICULARLY OVER THE MTNS AND HIGH DESERTS. NO SYNOPTIC SCALE TRIGGER IS EVIDENT...SO THE ACTIVITY SHOULD DEVELOP ON THE HIGHER PEAKS DURING TIME OF MAX HEATING. THE MASSIVE UPPER HIGH DRIFTS A BIT OVER THE NEXT FEW DAYS BUT ESSENTIALLY KEEPS US IN E TO SE MOIST FLOW WITH HIGH 500 MB HEIGHTS. LOOKS LIKE SOME DRYING OVER SOCAL ON THU AS A RIDGE AXIS BUILDS OVER THE AREA...AND UPPER WINDS STRENGTHEN CONSIDERABLY FROM THE SE. THIS SHOULD CONFINE THUNDERSTORMS MORE TO THE MTNS AND KEEP THEM MOVING. BY FRI...UPPER WINDS DECREASE A BIT AND THE RIDGE DRIFTS BACK TO THE N. SO IT LOOKS LIKE A BETTER CHANCE FOR MORE WIDESPREAD PROBLEMATIC THUNDERSTORMS WITH FLASH FLOOD POTENTIAL...ALTHOUGH MOISTURE DOES NOT INCREASE AGAIN UNTIL SATURDAY. ANY REDEVELOPMENT OF THE MARINE LAYER WILL DEPEND IF AN EDDY CAN SPIN UP IN THE BIGHT OR NOT. RIGHT NOW IT LOOKS LIKE THE MARINE STRATUS WILL BE MINIMAL NIGHTS AND MORNINGS THROUGH THE WEEKEND. LOOKS LIKE WE COULD SEE MORE WIDESPREAD CLOUDS...SHOWERS AND THUNDERSTORMS AS MOISTURE ASSOCIATED WITH THE REMNANTS OF HURRICANE EMILY MOVES OVER SOCAL AS AN EASTERLY WAVE ON SAT AND SUN. BY MONDAY...THE HIGH IS FORECAST TO DRIFT BACK OVER US WHICH WOULD DECREASE THE MONSOONAL FLOW FOR SOME DRYING NEXT WEEK...BUT CONTINUED WARM TO HOT INLAND. THE MARINE LAYER COULD RETURN ON MON AND TUE AS THE MONSOONAL FLOW WEAKENS. && .AVIATION... THE MARINE LAYER CONTINUES TO BE PUSHED OFFSHORE IN RESPONSE TO STRONG HIGH PRESSURE ALOFT AND AN EASTERLY FLOW OVER THE AREA. THIS WILL CONTINUE THROUGH THE NIGHT AND ON THURSDAY WITH SOME RECOVERY OF THE MARINE LAYER EXPECTED THURSDAY NIGHT INTO FRIDAY MORNING. AS A RESULT...MOSTLY VFR CONDITIONS ARE EXPECTED AT ALL AIRPORTS IN THE AREA INCLUDING THE TAF SITES. SCATTERED ALTOCUMULUS ABOVE 12000 FEET MSL WILL DRIFT WESTWARD ACROSS THE AREA FROM ARIZONA AND NORTHWEST MEXICO THROUGH THURSDAY. THE AIR MASS IS UNSTABLE ENOUGH FOR SCATTERED THUNDERSTORMS OVER THE MOUNTAINS AND DESERTS DURING THE AFTERNOON. BASES SHOULD REMAIN ABOVE 10000 FEET MSL. LOCAL MVFR VISIBILITIES FROM HAZE ESPECIALLY ALONG THE COAST...CNO/ONT/SBD AREA AND IN THE DESERTS. && .SGX WATCHES/WARNINGS/ADVISORIES...SPECIAL WEATHER STATEMENT FOR INCREASING MONSOONAL THUNDERSTORMS...SEE LAXSPSSGX. && PUBLIC...PG AVIATION...HORTON
