A storm cleanup day
Tuesday October 26, 2010
TUESDAY MORNING WAS WINDLESS HERE NEAR THE VILLAGE…..A BEAUTIFUL MORNING WITH A TEMPERATURE OF 31 DEGREES AND DEW POINT OF -5. THERE IS STILL A LOT OF STORM DEBRIS EVIDENT FROM THE HIGH WINDS OF SUNDAY…PINE NEEDLES….SOME BROKEN LIMBS…ETC.
NEW 12Z WRF TUESDAY HAS COLD SHORT WAVE INTO THE PACIFIC NORTH WEST AT THE MOMENT WITH SOME COOLER AIR MAKING ITS WAY INTO NORTHERN CA. LIGHT TO MODERATE WINDS WILL COME UP TODAY IN MAMMOTH. THE COOLER AIR WILL BE ESPECIALLY NOTICEABLE WEDNESDAY AM WITH TEMPS DOWN INTO THE TEENS AND 20S. WEDNESDAYS WEATHER WILL WARM UP AS A SHORT WAVE RIDGE MOVES OVER CALIFORNIA.
THE NEXT UPSTREAM SYSTEM WILL SLOW AS IT APPROACHES CALIFORNIA THURSDAY, DUE TO THE SLOW NATURE OF THE WEEKEND SYSTEM THAT CAME THROUGH OUR AREA SUNDAY NIGHT. THE SUNDAY SYSTEM NOW WELL EAST AND SLOWING….ALLOWS A SIGNIFICANT RIDGE TO BUILD FROM NORTHWEST MEXICO INTO THE ROCKIES CREATING A LOT OF SLOWING FOR THE THURSDAY/FRIDAY STORM.
I LOOKED AT THE OPERATIONAL 00Z….CANADIAN, UK, EC,AND GFS. ALL ARE IN AGREEMENT IN “NOT” CUTTING-OFF THE UP COMING TROF. HOWEVER, THEY ALL SLOW THE SYSTEM DOWN THURSDAY THEN RAPIDLY EJECT THE ENERGY THROUGH SOUTHERN CA FRIDAY/NIGHT. THUS THE TROF SPLITS AND DUMPS MOST OF THE PRECIP WEST OF THE SIERRA CREST WITH LIGHT AMOUNTS FOR THE EASTERN SIERRA THIS WEEKEND. THE KICKER TROF WILL COME THROUGH SUNDAY NIGHT. WILL KEEP AN EYE OUT ON THAT ONE TO SEE IF IT CAN DO BETTER HERE LOCALLY.
LONGER RANGE:
AS MENTIONED EARLIER, HEIGHTS REALLY RISE OVER THE FAR WEST MONDAY THROUGH TUESDAY WITH HEIGHTS BY TUESDAY AFTERNOON IN THE LOW TO MID 590S BY 00Z WEDNESDAY. THIS ACCORDING TO THE 00Z TUESDAY RUNS OF THE ECMWF AND CANADIAN…..THAT MEANS INDIAN SUMMER TO THE MAX! THE ECMWF HAS THE PATTERN PROGRESSIVE…..WELL SEE IF SHE HOLDS…:-)
PS: THERE HAS BEEN A RECENT JOG IN THE +SSTA POOL EASTWARD TOWARD THE DATELINE….WILL KEEP FINGERS AND TOES CROSSED THAT THIS WWP KEEPS MOVING EAST!
