AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SAN DIEGO CA 855 PM PST MON FEB 27 2006 .SYNOPSIS...A PACIFIC STORM WILL BRING PERIODS OF RAIN THROUGH TUESDAY EVENING. THE RAIN COULD BE HEAVY AT TIMES. STRONG WINDS WILL ACCOMPANY THIS STORM IN THE MOUNTAINS AND THE UPPER DESERT. THE SNOW LEVEL WILL START OUT AT VERY HIGH ELEVATIONS AND THEN LOWER TUESDAY AFTERNOON. DRY WEATHER IS EXPECTED WEDNESDAY AND THURSDAY BEFORE ANOTHER WEAKER STORM ARRIVES WITH RAIN AND SNOW THURSDAY NIGHT THROUGH FRIDAY. HIGH PRESSURE WILL BRING DRY AND WARMER WEATHER DURING THE WEEKEND AND EARLY NEXT WEEK. && .DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE... SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO COUNTIES. THE RAINS HAVE ARRIVED AND HAVE BEEN LOCALLY HEAVY IN SOME MOUNTAIN AREAS IN SAN BERNARDINO COUNTY WITH OVER ONE INCH REPORTED SO FAR. DOPPLER RADAR SHOWS A STREAM OF ECHOES EXTENDING WELL OUT TO SEA SO THE RAINS WILL CONTINUE THROUGH THE NIGHT. THE WATER VAPOR LOOP SHOWS THE STORM CENTER WELL TO THE NORTH...OFF THE N CA COAST... WITH A STREAM OF SUBTROPICAL MOISTURE MOVING OVER THE CWA FROM THE SW. IR ENHANCEMENT HAS DECREASED OVER THE PAST SEVERAL HOURS... SUGGESTING A GENERAL DECREASE IN RAINFALL RATES OUT TO SEA. THE LATEST NAM MODEL CONTINUES TO ADVERTISE 40KT PLUS WINDS AT 850 MB FROM THE SW OVERNIGHT. IF THE AIRMASS IS AS SATURATED AS THE MODELS PREDICT...MUCH OF THE MOISTURE WILL GET WRUNG OUT ON THE SW FACING COASTAL SLOPES. THERE IS VERY LITTLE IN THE WAY OF JET OR FRONTAL DYNAMICS FOR GENERAL HEAVY RAIN ON THE COASTS AND VALLEYS... SO IT APPEARS THE MAIN EVENT WILL BE ON THE COASTAL SLOPES TONIGHT WHERE SEVERAL INCHES OF RAIN ARE LIKELY TO FALL. AREAS OF STRONG WINDS WILL BE LIKELY IN THE MOUNTAINS MOIST SW FLOW CONTINUES THROUGH THE DAY TOMORROW UNDER CYCLONIC FLOW ALOFT SO PERIODS SHOWERS MAY PERSIST MUCH OF THE DAY...ALTHOUGH WIDESPREAD HEAVY RAINFALL IS NOT EXPECTED. COOLER AIR ALOFT IS STILL EXPECTED TO LOWER SNOW LEVELS IN THE MOUNTAINS DURING THE DAY TO AROUND 6500 FEET SO SOME LIGHT ACCUMULATIONS AT RESORT LEVELS ARE POSSIBLE. THE FLOW FINALLY FLATTENS A BIT WED WITH A HINT OF WEAK RIDGING. THIS SHOULD DRY OUT THE ATMOSPHERE ENOUGH TO TURN OFF ANY LINGERING SHOWERS IN THE MTNS. THE CYCLONIC FLOW RETURNS AGAIN THU...AND BY THU NIGHT AND FRI WE WILL HAVE ANOTHER CHANCE OF SOME LIGHT RAIN...AND SNOW IN THE MOUNTAINS. A FORECAST UPDATE WAS ISSUED AT 825 PM. && .AVIATION...
