As of 8:45 am Monday, Mammoth Pass has picked up 7.96 inches of water since AR # 2 started Saturday. Add that to AR #1 of 8.44 and you get about 16.5 inches of water. That a lot and there is possibly another 6 more inches to come by Thursday Night!. Fridays storm is not in the future anymore, so the extreme amounts of 25 to 30 inch’s are unlikely now. However, 20 to 25 inches is still in the picture by Thursday night of this week. Considering that about 43 inches of water is average, we are well over 1/2 of our winters worth precipitation when you add October, November and December! We are possibly closing in on a full Winter’s worth quickly!!
Latest Satellite water vapor motion shows an intense upper low west of Washington and Oregon coast. This upper wave according to the models will be replaced by the larger scale cyclone itself, as it moves eastward. The timing of this feature is to move it through Mammoth Lakes Tuesday night with an intense vertical motion field. Thus the main IOP, (Intensive operational period) will be Tuesday night into Early Wednesday morning where snowfall rates may be in the 2 to 4 inch per hour range for a time…. The Town of Mammoth at the 8000 foot level is likely to experience 3 feet to as high as 5 feet of snowfall between Monday AM and Thursday afternoon. Again the heaviest snowfall rates are likely Tuesday night…..
Outlook: We are still expecting a partly cloudy but fair weekend with high in the 20s. Lows in the single digits. Skiing will be on cold packed powder with deep powder as well. Mammoth Mountain is likely to have received totals over the upper mountain in excess of 18 feet….
