AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SAN DIEGO CA 930 AM PST TUE DEC 28 2004 .SYNOPSIS...A STRONG PACIFIC STORM WILL BRING PERIODS OF RAIN...HEAVY AT TIMES...THROUGH WEDNESDAY. SNOW WILL OCCUR AT THE HIGHER ELEVATIONS. A FEW THUNDERSTORMS WILL ALSO OCCUR. A FLASH FLOOD WATCH IS IN EFFECT TODAY THROUGH WEDNESDAY...WITH A WINTER STORM WARNING ABOVE 6500 FEET. STRONG GUSTY WINDS WILL ACCOMPANY THIS STORM...ESPECIALLY IN THE MOUNTAINS THROUGH WEDNESDAY MORNING. COOL AND UNSETTLED WEATHER WILL CONTINUE WITH A CHANCE OF SHOWERS THROUGH THE END OF THE WEEK. && .DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE... SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO COUNTIES. RAIN IS SPREADING OVER THE AREA...AND SOME OF THE OROGRAPHIC AREAS ON THE SOUTH SLOPES OF THE SAN GABRIELS AND ALSO SOME COASTAL AREAS HAVE RECORDED MORE THAN ONE INCH SO FAR DUE TO FRONTAL LIFTING THERE. RAIN RATES HAVE BEEN MOSTLY FAIRLY STEADY SO FAR. SOME LOW-LEVEL E/SE FLOW HAS BEEN KEEPING RH LEVELS LOWER NEAR THE SURFACE AND THUS KEEPING SOME OF THE PRECIP TOTALS A BIT LOWER. HOWEVER...ACARS SOUNDINGS FROM PLANES OVER THE COASTAL WATERS JUST WEST OF LINDBERGH FIELD SHOWED WIND SPEEDS UP TO 55 KNOTS AT 2500 FEET...AND THIS IS CONTRIBUTING TO THE GALE FORCE WINDS OVER THE COASTAL WATERS. ALSO...BURNS CANYON IN THE SBD MTNS RECORDED A GUST OF 59 MPH EARLIER THIS MORNING. SNOW WAS OCCURRING ABOVE 5500-6000 FEET NORTH SLOPES IN SBD COUNTY TO 6500 FEET ELSEWHERE. WRIGHTWOOD HAD RECEIVED 4 INCHES...AND BIG BEAR HAD RECEIVED 1 INCH. THE CURRENT IMPULSE WILL EXIT THE AREA THIS AFTERNOON...AND THE BIGGEST THREAT WILL BE THE BANDS OF PRECIP WHICH WILL PRODUCE TRAINING. WHERE THESE BANDS INTERSECT THE COASTAL SLOPES WILL BE WHERE THE THREAT OF FLOODING WILL BE HIGHEST...ESPECIALLY IN S ORANGE COUNTY AND NW SAN DIEGO COUNTY. AFTER THE IMPULSE MOVES THROUGH...MORE SHOWERS WILL CONTINUE AT TIMES THIS AFTERNOON/EVENING DUE TO THE MOIST FLOW. A BIT MORE OF A LOW-LEVEL WESTERLY COMPONENT WILL ALSO MAKE THE AREA MORE FAVORABLE FOR PRECIP...EVEN BETWEEN THE IMPULSES. THE NEXT IMPULSE...NOW WRAPPING AROUND THE LARGE CENTER OF LOW PRESSURE...WILL MOVE THROUGH LATE TONIGHT/EARLY WED...AND THIS WILL LIKELY PRODUCE SUBSTANTIAL RAINFALL. INSTABILITY WILL BE HIGHER...SO CONVECTION WILL BE MORE LIKELY...AND HIGH RAINFALL RATES...LOCALLY REACH ONE INCH PER HOUR...WILL BE POSSIBLE. WATERSPOUTS WILL BE A THREAT OVER THE COASTAL WATERS DUE TO THE INSTABILITY/STRONG CYCLONIC FLOW. ETA HAS ANOTHER VORT MAX BEHIND THE 2ND IMPULSE WED AFTERNOON...SO THIS MIGHT PROLONG THE SHOWERS...THOUGH THE SUPPORT FOR HEAVY RAIN WILL HAVE SHIFTED TO THE EAST. TOTAL PRECIP AMOUNTS ARE PROJECTED TO BE A BIT LESS THAN ONE INCH IN THE LOWER DESERTS...1-2 INCHES IN THE HIGH DESERTS...2-3 INCHES IN COASTAL/VALLEY AREAS WITH LOCAL 4 INCHES TOTALS WHERE CONVECTION OCCURS...AND 3-6 INCHES IN MOST OF THE MTNS. OROGRAPHICALLY FAVORED MTN SLOPES SHOULD STILL GET 5-10 INCHES. THE LONG-RANGE BIG PICTURE IS FOR CONTINUED BROAD TROUGH OVER THE WEST COAST THROUGH EARLY NEXT WEEK. OCCASIONAL SHORTWAVES WILL ROTATE AROUND THE LOW AND BRING MORE CHANCES OF PRECIP. THE BEST CHANCES RIGHT NOW APPEAR TO BE FRIDAY AND NEXT MONDAY. && .SGX WATCHES/WARNINGS/ADVISORIES...
