AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SAN DIEGO CA 117 PM PST TUE MAR 22 2005 .SYNOPSIS...A STRONG DISTURBANCE OVER THE EAST PACIFIC WILL RACE INTO THE SOUTHLAND OVERNIGHT WITH RAIN AND A SLIGHT CHANCE OF THUNDERSTORMS. INSTABILITY AND MOISTURE WILL CONTINUE PERIODS OF RAIN AND SHOWERS INTO FRIDAY. ANOTHER ROUND OF WIDESPREAD MODERATE PRECIPITATION IS POSSIBLE LATE THURSDAY AND THURSDAY NIGHT WITH LOWER SNOW LEVELS. FAIR AND WARMER FOR THE WEEKEND UNDER BUILDING HIGH PRESSURE. && .DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE... SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO COUNTIES. LATEST WATER VAPOR LOOP SHOWS SHORTWAVE AMPLIFYING OVER THE E PACIFIC NEAR 35N/130W OR ABOUT 350 NM W OF PT. CONCEPTION. MODELS HAVE BEEN TRENDING FARTHER S WITH THE JET ROUNDING THE BASE OF THIS SYSTEM. THE 18Z NAM MODEL NOW BRINGS IT INTO S SAN DIEGO COUNTY THIS EVENING. VISIBLE SATELLITE IMAGERY SHOWS A NARROW BAND OF RAIN STRETCHING FROM THE LA BASIN...SW WELL OFFSHORE...THEN A THICKENING BAND BEHIND THAT ASSOCIATED WITH THE JET APPROACHING FROM THE WEST. NAM PRECIP HAS BEEN WAY UNDERDONE SO FAR AT POINTS ALONG THE COAST TO THE NORTH...SO IT MAY NOT BE ADEQUATE WITH THE QPF OVER THE FORECAST AREA TONIGHT. DYNAMIC LIFT ASSOCIATED WITH THE FAVORABLE LEFT FRONT QUADRANT OF THE JET AND ASSOCIATED INSTABILITY WILL PRODUCE AT LEAST A SLIGHT CHANCE OF THUNDERSTORMS AS THIS MOVES THROUGH BY MIDNIGHT. DEEP MOISTURE AND STRONG ONSHORE FLOW WILL KEEP SOME LIGHT PRECIPITATION GOING WED AND THU WITH THE BEST CHANCES ON THE COASTAL SLOPES. BY THU...MODELS SHOW REINFORCEMENTS ARRIVE AS ANOTHER SHARP SHORTWAVE TROUGH AND ASSOCIATED STRONG JET MOVE INTO THE S PART OF THE STATE WITH MORE MODERATE TO LOCALLY HEAVY RAINFALL POSSIBLE. THIS SYSTEM IS STILL WAY OUT NEAR THE DATE LINE...SO TIMING AND STRENGTH...AS WELL AS FINAL TRAJECTORY COULD END UP CONSIDERABLY DIFFERENT THAN CURRENTLY FORECAST. EVENTUALLY A DEEP...COLD LOW IS CARVED OUT OVER THE WESTERN STATES WITH NW FLOW OVER CA BY FRI. THERE SHOULD STILL BE A FEW SHOWERS IN THIS FLOW BUT AMOUNTS SHOULD BE LIGHT. .LONG TERM...MEDIUM RANGE GUIDANCE STILL POINTS TOWARD A DRY AND WARMER WEEKEND WITH BUILDING HIGH PRESSURE ALOFT. THE UK AND EU MODELS ARE MORE PROGRESSIVE WITH THE UPPER LOW INLAND WHILE THE GFS AND NAM MODELS TRY AND HOLD IT BACK A BIT MORE. IN EITHER CASE... THE WEEKEND STILL LOOKS DRY. THIS MAY NOT BE THE CASE NEXT WEEK AS THE UK AND GFS MODELS ARE HINTING AT MORE RAIN. && .SGX WATCHES/WARNINGS/ADVISORIES... FLASH FLOOD WATCH...........SEE LAXFFASGX.
