The Weather worked our pretty well for the last weekend of Skiing and Boarding on Mammoth Mtn. The cold weather early in the Weekend set the stage for freezing temps each morning and so the snow really set up over night for the Morning Thaw…..
The weather this week will be highlighted by stronger ridging building in ….eventually from the South/Southwest. Currently….A pretty strong Tropical/Subtropical High now centered in the southern Sea of Cortez will retrograde west through mid week and combine with shortwave ridging now approaching the Eastern Pacific.
Mondays 500mb/and surface weather maps still showed our weather being effected by weak trofing aloft and the thermal trof over the Great Basin. Over the next few days, a combination of increasing heights aloft and the focus of surface convergence associated with the Thermal Trof redeveloping over Western Calif, will put an end to the pesky zephyr winds that occurred Monday afternoon. This mornings 12z Tuesday WRF surface chart showed an inverted surface Trof aligned just inland from the Bay Area and over the coastal range. This will result in an ENE off Sierra Flow Toward the Bay Area, Wednesday and Thursday. This effectively kills the afternoon Zephier for Wednesday and Thursday afternoon and so Wednesday/Thursday will be best days for Local Golf…even in the late afternoon! By Friday Noon, the area of surface convergence begins to shift east again, over the Sierra by about 18Z to 20Z for a Chance of Thunder. There may be a light Zephier as well By late afternoon. By Saturday Afternoon Zephier winds will be in full swing with gusty west winds and little change in temps. Any Thunder will be confined to the White Mtns eastward.
This weeks high temps will peak Friday in the mid to upper 70s……night time lows in the mid 30 to the upper 40s….
Sunday’s Weather will continue the transition back to Trofing with Breezy weather and cooler temps returning Sunday into Monday. The cooling will continue part of the following week……Temps will be normal to below normal next week…..with hot weather returning to the Eastern Half of the Country.
