Monday afternoon:

Last 12z and 18z Monday modeling continues the trend of more energy swinging off shore then over the sierra, (over water trajectory) to the point that its hard to ignore the possibility of snow showers Tuesday and into the evening. Not a big deal but with most forecasters not putting anything other then a slight chance. FYI, It looks more likely to the Dweeb this afternoon then not for Tuesday/evening. There is even the possibility of an inch of snowfall here over Mammoth Mt!

Dry and Mild Next Week!

Longer range shows a possible storm about Mid Month or just after!


Although seasonal temperatures were expected this weekend, another NW slider was taking shape over the pacific northwest. Winds this morning at 10:00AM were gusting to 50 MPH over the top of Mammoth Mt with light breezes in the Town of Mammoth Lakes. Seasonal highs; Low to mid 60s with lows in the upper 30s and 40s are expected this weekend.

Early this new week a reinforcing shot of cold air will dig South over the far west, carving a stronger Trof over the Great Basin. Although this is similar to last weeks system, there is not much over water trajectory of the upper jet of any precipitation this time. However, the very latest Saturday 12z model runs seem to be digging this system ever slightly westward, enough for some possible snow showers Tuesday over the Central Sierra. With 700MB temperatures plunging again, nighttime lows are headed for the upper teens and twenties and daytime highs in the upper 40s Tuesday. Once the chilly air gets in here Monday and Tuesday, temperatures well remain below normal for a good part of next week before recovering that following weekend.

Longer Range:

The ECMWF week two and CFS models seem to be trending toward a stronger system moving in from the west, the middle of October that may bring significant snowfall to the high country…

Stay Tuned………..;-)
