THE PACIFIC STORM THAT MOVED THROUGH THE EASTERN SIERRA BROUGHT THE FIRST GOOD SHOT OF SNOWFALL FOR THE TOWN OF MAMMOTH. AMOUNTS UP TO 7 INCHES FELL AT THE VILLAGE AND UP TO A FOOT AT THE BASE LODGE WITH POSSIBLY AS MUCH AS 18 INCHES OVER THE CREST AS MAMMOTH PASS REPORTED 1.67 INCHES. THIS IS ALL JUST IN TIME FOR THE OPENER ON THE 11TH. IT’S COLD NOW AND MAMMOTH MOUNTAIN WILL ADD TO THE BASE DAY AND NIGHT WITH MAN MADE SNOW.


TUESDAY-WEDNESDAY


LATEST 12Z GFS AND WRF ARE BRINGING IN ANOTHER SHORT WAVE WEDNESDAY. THE TRAJECTORY SUGGESTS THAT JUST SHOWERS WILL FALL AS IT MOVES MAINLY SOUTH AND WEST OF THE CENTRAL SIERRA. AN INCH OR TWO IS POSSIBLE AT THIS TIME. ANOTHER REINFORCING SHOT OF COLD AIR WILL KEEP THE SNOW GUNS HAPPY WEDNESDAY. AFTER A BUMP UP INTO THE 40S TUESDAY….TEMPS WILL DROP INTO THE IN THE 30S AGAIN MUCH LIKE TODAY WEDNESDAY.


THE REST OF THE WEAK AND BEYOND…………………


AMPLIFICATION OF THE EASTERN SIERRA RIDGE WILL TAKE PLACE TOWARD THE WEEKEND AT ABOUT 140 WEST. SHORT WAVE ENERGY WILL DROP SSE OUT OF WESTERN CANADA TOWARD THE NORTHERN ROCKIES WITH THE MAIN FOCUS FOR PRECIPITATION EAST OF THE DIVIDE.

THIS IS A DRY PATTERN FOR THE EASTERN SIERRA THURSDAY THROUGH THE WEEKEND. TEMPS WILL RISE TOWARD 50 BY THE WEEKEND.


THERE AFTER…..

THE 6 TO 10 DAY AND 8 TO 14 DAY MEAN HEIGHTS AT HT 500 SHOW THE EASTERN PACIFIC RIDGE REMAINING BETWEEN 140 AND 135 EAST.

THIS SHOULD KEEP THE PATTERN DRY THROUGH MID MONTH. WITH TEMPERATURES TRENDING BACK INTO THE 50S NEXT WEEK AS THE EASTERN PACIFIC UPPER HIGH NUDGES A BIT CLOSER TO THE WEST COAST. AS LONG AS THE UPPER HIGH REMAINS WELL OFF SHORE AND THE UPPER FLOW REMAINS NORTH NORTH WESTERLY…. “SEVERE” INVERSIONS SHOULD NOT BE A PROBLEM FOR SNOW-MAKING. HOWEVER, SOME OF FANTASY OPERATIONAL MODEL RUNS  ARE PROGRESSING THE EASTERN PACIFIC HIGH INTO THE WEST COAST  ABOUT THE 19TH/20TH.
