"WINDY WEATHER TO PREVAIL TODAY THURSDAY WITH A FEW SNOW SHOWERS POSSIBLE OVER THE UPPER ELEVATIONS......THEN DRY FRIDAY.....MOIST SUBTROPICAL TAP RETURNING THIS WEEKEND WITH PRECIPITATION RETURNING TO THE EASTERN SIERRA SATURDAY....A SIGNIFICANT STORM FORECASTED FOR EARLY NEXT WEEK....MAMMOTH PASS ABOUT 87% OF NORMAL FOR THE MARCH 1ST DATE....NO CHANCE NOW TO DOUBLE WINTERS PRECIP IN THE MONTH OF FEBRUARY....BUT GOOD DENT IN DROUGHT SO FAR AND MORE COMING!"
DISCUSSION:
LATEST 12Z THURSDAY OPERATIONAL GFS HAS A COLD ARCTIC LOW OVER WASHINGTON STETS THIS MORNING WITH A UPPER HIGH CENTERED NEAR CABO SAN LUCUS, MEXICO. THE UPPER JET IS SQUEEZED BETWEEN THESE TWO FEATURES AND IS MODERATE OVER CENTRAL CA.....NOT MUCH MOISTURE TO WORK WITH BUT SFO RADAR HAD SOME SHOWERS APPROACHING THE CENTRAL SIERRA AT 8:00AM. A FEW SHOWERS ARE POSSIBLE ABOUT AS FAR SOUTH AS YOSEMITE, BUT NO BIG DEAL.
THE UPPER JET THEN LIFTS NORTH AGAIN THE NEXT 24 TO 48 HOURS IN RESPONSE TO A STRONG SHORT WAVE DIVING SOUTH OUT OF THE GULF OF AK NEAR 40N/142W SATURDAY AFTERNOON. THIS SYSTEM WILL RE-ENERGIZE THE OLD UPPER CUT OFF LOW THAT'S BE OUT THERE AT ABOUT 140WEST. THIS OLD LOW GETS KICKED OUT AND UP INTO THE PACIFIC NORTHWEST AND NORTHERN CA. SATURDAY. HEIGHTS ARE ABOUT 570DM OVER MAMMOTH AND LIGHT RAIN OR RAIN SHOWERS A POSSIBILITY. HEIGHTS LOWER ABOUT 60DM THE FOLLOWING 24 HOURS AND SO SOME COOLER ARE WILL WORK INTO THE AREA SUNDAY NIGHT AND INTO MONDAY MORNING. HOWEVER....THE COOLEST AIR MAY NOT ARRIVE UNTIL LATER TUESDAY FOR MUCH LOWER SNOW LEVELS. THIS APPEARS TO BE ANOTHER GOOD SIERRA CEMENT TYPE STORM FOR THE UPPER ELEVATIONS UNTIL THE COLDER PORTION OF THE SYSTEM ARRIVES SOME TIME BETWEEN THE EARLY TO MIDDLE PART OF NEXT WEEK. OUR LOCAL MOUNTAINS MAY BENEFIT WITH 2+ FEET BY TUESDAY OR WEDNESDAY.
