Although Mammoth Mt is closed, they reported 4 to 6 inches of snow from the Sunday afternoon/night system. The last in the series will be moving in Tuesday, bringing more wind and snowfall into early Thursday AM   This would be considered a low end moderate storm. The main upper low is more over land now than off shore. However, there is still plenty of upper jet coming in from off shore to give us good west-side up-slope, and possibly 6 to 12 inches over the upper elevations and along the crest. The snow will be cold and powdery by Wednesday.  In town, light amounts are expected with between 3 and 6 inches between Tuesday and Thursday.  This looks to be the last in the series of weather systems to affect our area.  In reference to the discussion below, the Eastern Pacific Oscillation is going positive with lower pressure in the Gulf of Alaska for the first week of April. That usually allows for 500mb height rises along the west coast, and a northward retreated upper jet.  It will be colder that normal through Friday with high temps cooling to the upper 20s by mid week and lows in the teens….

Chilly Weather with below normal temps are expected to continue through mid week.  High temps will be mostly in the 30s with lows in the teens and twenties.

There are two weather systems that will bring more snowfall to Mammoth.  The one Sunday night/Monday AM is a weakening system that will being light snowfall to town…..Between 2 to 4 inches.  The system Tuesday and Wednesday could bring another 4 to 7 inches in town by Thursday AM. Will Update amounts for the mid week storm on Monday.

The last in the series of storms is expected to bring quite a bit of wind Monday Night through Tuesday Night  Teleconnections show that the -EPO will be going positive. That is usually accompanied by the Polar Jet retreating to our north again. Temperatures are likely to return to near normal during week 2.

The following weekend looks cool with a NW flow aloft. There is a small wave coming through late Saturday that may bring some snow showers.  We’ll see…..

Otherwise, although the GFS has more storminess the following week….The Eastern Pacific Oscillation goes positive.  That means that it will be more difficult for storms to get in here…..But not impossible….

 

Stay Safe…..Stay Healthy…..Listen to your officials….
