Weather Guy Forecast 11-13-2012

Mammoth Weather Guy Update – 11-13-2012 – Next Update Friday 4pm

A high pressure ridge will hold over the Mammoth area through most of Thursday for dry weather with generally decent snow making conditions at night.

Clouds are expected to increase on Thursday afternoon and evening leading to light snowfall overnight with minor accumulations expected by Friday morning. The snow is associated with a slow moving area of low pressure that will track through the Sierra on Friday and into Saturday afternoon.

The storm system is coming from the southwest and won’t be nearly as cold as the last storm (snow levels around 7-7500 feet), but the moisture tap is much better and overall precipitation amounts will be larger. However, the snow ratios will be lower with this one and probably in the 8:1 range which means the snow will be more like Sierra cement and not as fluffy, making it great base snow.

That storm will be followed by another one on Saturday night and into Sunday under lower snow levels (6-6500 feet) for another round of moderate to heavy snow at times through Sunday afternoon. There will probably be more wind with the second storm, but it won’t be too bad by Mammoth standards.

A third storm will then move on Monday and the focus of that storm will be farther North with Mammoth probably on the southern boundary for moderate snowfall before the snowfall ends on Tuesday morning.

The details with the pattern still are not certain, but moderate to heavy amounts of snowfall are expected starting on Friday and lasting through the weekend.

Dry weather will likely return by next Wednesday with continued fair weather through the Thanksgiving Day Holiday weekend. The next chance for snow might not be until the last week of November or later.
