Our Weather in Mammoth is way too nice for the middle of January!  The Dweebs were in short sleeve shirts today as highs approached 60 degrees in Town.  Lows at night are now above freezing….. It will be warmer the next few days as the current ridge Trof pattern peaks out.  Remarkably,  It is quite unusual that our high temperatures in Mammoth are about the same as Reno, NV. However, that is testament to strong ridging in January with strong temperatures inversions as well.

Our Ridge Pattern peaks out Friday, with highs in the low to mid 60s!  Next week should cool down a bit.   As the eastern pacific ridge begins to slowly back up, cooler air will begin to spill southward through the Great Basin., Monday and Tuesday, High temperatures will be back down into the 40s next week with nights seasonally in the teens.

Pattern in Transition:

I just had a look at the 12Z ECMWF Ensemble, 5 day means.   Its a good guide in telling you where the pattern is going and how it will effect a particular area, weather wise.  The Eastern Pacific Ridge is currently between 130 and 125west. Over the next 24 to 48 hours, its positive tilt and height anomaly will give our state an exceptionally beautiful few days with near record highs Thursday and especially Friday.   Looking at next weeks weather, the ridge in the 5 day means continues to retrograde westward. Its expected that it shifts west about 1000 miles from its current position by next Friday the 22nd. The long wave Trof backs west as well to the Rockies. This initiates the very beginning of a storm track with NW sliders and a possible unsettled period that following weekend. Temperatures will be much cooler. As we go through that 4th week and final days of January, the eastern pacific ridge, as progged by the ECMWF, retrogrades west to 165 west.  If that is the case, there will be a lot of storminess between the following weekend and the end of the month.
