    FRI FEB 24 2017
     
    WEATHER DISCUSSION:
     
    Sunny, cool and dry today as an infrequent visitor, high pressure that is, makes a visit. By Saturday and into early next week, a couple of weak storms will swing thru from the north. These are not going to have that heavy moisture tap of the last few, but still 1 feet of new in the higher elevations by next Monday. Snow levels will be lower, as these systems originate from the GOA, so snow levels could drop down to 3,000 feet. By Tuesday, a flattened ridge of high pressure attempts to build in, for drier conditions….DMATT

    THU FEB 23 2017
     
    WEATHER DISCUSSION:
     
    Generally a break in the weather today and tomorrow (except some scattered snow over the mountains). Mammoth Mountain has now broken the 500 inch mark, with 510 inches for the season. So some quiet weather to take a breath. Problem is another storm looms on the horizon, as the forecast models suggest precipitation Sunday into Monday. This system looks to have less access to deep moisture. With the cold air of late, snow levels will be lower than the previous systems. Tuesday / Wednesday sees the possible re-development of a ridge of high pressure, drying things out. Stay tuned for my fine tuning on this…DMATT

    WEATHER DISCUSSION:
     
    Mammoth Mountain (Main Lodge) is now sitting at 488 inches of snow this season. Speaking of snow, it continues today heavy at times, with levels at abut 7,000 – 8,000 feet in Mono County. This storm has brought some of the most powerful Sierra Crest winds in many years, with peak gusts to 199 mph! 2 – 4 feet is possible in the higher elevations. A weaker, colder system moves in on Wednesday morning bringing mostly very cold air to the area. Looks like right now, a break on Thursday into Friday, before unsettled weather returns over the weekend. So stay tuned…DMATT

    MON FEB 20 2017
     
    WEATHER DISCUSSION:
     
    With all the snow we have received recently, Mammoth Mountain now has a season total to 480 inches. Another system will move in today, powered by a very strong Atmospheric River. It brings with it, extreme amounts of heavy rain and snow and the possibility of flooding thru this evening. Snow levels will run about 7,500 – 8,000 feet with another 2 – 4 feet over the higher elevations. Strong winds gusting to 60+ mph area possible in Mono County. Precipitation continues off / on into Wednesday, lingering into Thursday. Stay tuned…DMATT

    WEATHER DISCUSSION:
     
    More snow today and tonight tapering off Saturday. Another foot of snow possible in the higher elevations. Looks like a small break between storms later Saturday into Sunday morning. Sunday afternoon the winds pick up once again, ahead of what could be the strongest storm of the series. I expect heavy rain / snow and maybe some 2 – 3 feet of new snow in the higher elevations by Tuesday. System pushes south on Tuesday with lingering precipitation on Wednesday. A brief break in the action on Thursday, as high pressure tries to establish itself. With all this moisture, the Oroville area looks to get up to 1+ inch rain by Tuesday.
