First its the heat…then its the humidity!…Bishops Heat has Peaked shattering old record of 105 Monday with 109….Now add humidity….Temperatures to slowly drift downward beginning today……
Tuesday July 2, 2013
Dew points were up this morning with mid 40s widespread. Lots of sunshine this morning will guarantee an active TSRW set up for the high county with POPs north of 40% this afternoon and evening for the Mammoth Area. Mammoth had a high of 88 yesterday at the 7700 foot level.
Latest IR shows lots of mid and high level moisture streaming NW from SE California. Showers and thunderstorms are occurring in the southern most areas of Inyo County at the moment. The moisture is moving our way! Dew points will continue to rise making it feel humid and at the same time making it more difficult to challenge yesterdays high of 109 in Bishop. This is the beginning of the end of the great heat wave of the Central and Southern Great Basin of 2013. One that will go down in the record books as both one of the earliest, strongest and longest heat waves for Eastern California, Western and Southern Nevada.
So expect rain and thunder this afternoon. Heat waves like this usually break with thunderstorms on the back end as the dome of high pressure weakens… it usually does so with a much more unstable air mass. Our air mass is super heated now……add moisture and add the little impulses circulating around the upper high and you get the ingredients for some very good Thunderstorms. At the moment, precipitable water amounts are not excessive, at around in inch…good of some wetting rains. But let’s see what happens tomorrow as the upper high winds down.
Drying is expected to begin Thursday night and by the weekend, a dry SW flow is expected…..Returning our weather to more normal dry conditions with high temps in Mammoth Lakes in the low 80s. and lows in the 40s.
