Final Waves of Strong Pacific Storm Begin To Come Ashore
Posted by: silverstripes, 18:24 GMT le 06 janvier 2008 +0
Per SBkaren's request I am starting a blog for the Lake Arrowhead area. :) My first entry for the area will touch on the fact that I have received somehwere in the vicinity of 9 inches of rain since Friday afternoon. Unfortunately, I lost power when the bulk of precipitation hit Friday night into Saturday morning)so my online weather station data does not reflect the huge amounts of rain we received. We started to get granular type snow last night but it turned back into rain shortly after it was starting to stick but this morning we have about an inch of slushy accumulation and it is coming down as a mix still since the temps are hovering just above freezing. Below is a portion of this morning's NWS discussion.

.SYNOPSIS...
A POWERFUL STORM OVER THE WEST COAST WILL CONTINUE TO BRING SHOWERS TO SOUTHERN CALIFORNIA THROUGH MONDAY MORNING. THE HEAVIEST PRECIPIATION WILL BE TONIGHT. HEAVY SNOW IS EXPECTED ABOVE 5500 FEET IN THE MOUNTAINS ALONG WITH GUSTY MOUNTAIN AND DESERT WINDS. BRIEF HIGH PRESSURE WILL BRING FAIR WEATHER TUESDAY...BUT ANOTHER VERY WEAK SYSTEM WILL BRUSH SOUTHERN CALIFORNIA WITH A SLIGHT CHANCE OF SHOWERS LATE TUESDAY NIGHT AND EARLY WEDNESDAY. HIGH PRESSURE WILL BUILD MORE FIRMLY THE LATTER HALF OF THE WEEK BRINGING FAIR AND WARMER WEATHER...AND POSSIBLY OFFSHORE FLOW BY NEXT WEEKEND.

A PLUME OF MOISTURE CONTINUES TO STREAM INTO SOCAL THIS MORNING SHOWN BY THE SATELLITE PIX. RIGHT NOW THERE IS NO BIG FORCING MECHANISM TO TAKE ADVANTAGE OF ALL THAT MOISTURE SO SHOWERS TODAY WILL BE MOSTLY LIGHT. WINDS WILL CONTINUE STRONG MAINLY IN THE UPPER DESERT AND SBD MTNS. THE SNOW LEVEL IS DOWN TO ABOUT 5200 FEET THIS MORNING BUT WITH SO MUCH WATER ON THE GROUND...THE SNOW IS VERY SLUSHY UNDER 6000 FEET AND WILL HAVE DIFFICULTY PILING UP. MOSTLY LIGHT SNOW SHOWERS WILL CONTINUE ABOVE THAT LEVEL...WITH MUCH GREATER ACCUMULATIONS ABOVE 6000 FEET. SNOW LEVELS WILL DROP DOWN TO 4500 FEET OR SLIGHTLY LOWER TONIGHT. THE LAST WAVE OF THIS STORM LOOKS QUITE POTENT FOR TONIGHT. IT WILL COME DOWN FROM NORCAL TODAY AND IT LOOKS QUITE WET BETWEEN 10 PM TONIGHT TO ABOUT 8 AM MON. PRECIP WILL TAPER OFF FROM NORTHWEST TO SOUTHEAST AFTER SUNRISE. AFTER ALL IS DONE MON...STORM TOTALS MAY END UP VERY NEAR THE FORECAST STORM TOTALS INDICATED FROM LAST THU (2 TO 5 INCHES COASTS AND VALLEYS...6 TO 12 MTNS...0.50 TO 1.25 DESERTS).
