Weary Mammoth residents ready themselves for another onslaught of snow over the next 5 days. The Dweebs are betting that this current series is going to be the last for the season as far as for the amounts over a 5 day period. IE  the last big 5 day dump. Wishfull thinking?

Sure we will get more snow. However, the Dweebs doubt that it will come in the mass amounts that are expected through next Monday morning.


For one MJO; there is an MJO that is rapidly developing in phase 4 and progressing to phase 5 that will have the effect of building a ridge closer to the west coast next week. The MJO US Composites adjusted for climo for the month of April favors above normal temps and below normal precip in the first week of April or while it transits phase 5 toward 6 then 7.  We should be ridging up real good during the month April!

In the meantime the combination of a strong block over Central Canada and the Hudson Bay low that is set up well east of its normal position has:

1. Allowed a long wave trof to set up just off the west coast

2. Created an excessive wave length coast to coast

.3. The long wave upper ridge is located along 170west with the key height anomaly near 40 north.

Expect about 5 more day of this, before a significant pattern change sets up next week that will be both dryer and warmer.

Expected QPF through Monday AM…..7.00 inches for the crest.  IE 3-4 feet of snow for the town of Mammoth and 6 to 7 feet for the upper mountain by Monday AM.

Well we make the FAB 600 inch market?   It will be close this week!
