Late Summer Heat Wave to give to a few thunderstorms Wednesday then a little cooler over the holiday weekend…..A dry weekend is expected with above normal temperatures….
Tuesday August 27, 2019
Some light North East Flow developed early this morning bringing some light smoke from the Spring Fire into Mammoth. That pattern is not likely to occur Wednesday with an increase of westerly flow. Thunderstorm action should it occur, would be in the late morning for Mammoth, (Just a slight chance) as westerly afternoon winds push storms off to the east of highway 395. By Wednesday night, a weak Trof of low pressure pushes through to the north of us and flushes moisture out to the east. This will insure sunny, smoke free skies!
Expect a stronger Zephyr Thursday afternoon….
High temps will pull back to the upper 70s which is still above normal for this time of the year. The extended outlook keeps above normal temperatures in our forecast for the next 6 to 10 days. It appears that we will get more of the summer heat that was so late to start this year for the next few weeks….
Normal highs in Mammoth this time of the year are in the low 70s with lows in the 40s. High temperatures have been running in the upper 70s to mid 80s the past 5 days. Tuesday the 27th, the high temperature was 83 degrees with a low of 53. On Monday the high was the warmest of the year at 84 degrees. Pretty much what you would expect in mid July.
According to climo….There is likely to he a cool trof around the 3rd week of September, but at the moment, enjoy all the warmth and sunshine!!
Happy Labor Day weekend!

Extended Models Suggest that the warmest temperatures of the summer may still lie ahead…..Some Seasonal wind possible by end of next week….
Saturday August 17, 2019
Some of the finest weather in the eastern sierra in years, continues this weekend with daytime highs in the mid 70s and lows at the night in the 50s. Afternoon zephyr winds have been typical, in the 10 to 20 MPH range, with late afternoon breezes up to 25 MPH at times today Saturday, and tomorrow Sunday expected…. Smoke from a few lighting caused fires to the NNE has thus far been minimal in Mammoth, due to periodic weak trofing to the west and its resulting WSW flow aloft. The upper air pattern should continue to be favorable for clean air conditions at least through Monday this upcoming week. Beyond that, the continental high will build back again by mid week, increasing our temperatures and bringing a return of some light morning easterly flow. This will do two things. 1. We will experiences our highest temperatures so far this Summer by Wednesday. 2. If fires continue to burn to the NNE, conditions may turn hazy again by mid-week, however mainly during the morning hours, until the afternoon Zephyr winds kicks in. The mid to late Summer heat wave will last through Friday. Thereafter, it all depends upon which global model you prefer. The European Model develops light SE flow by Saturday or Sunday. So some seasonal wind/Monsoon for thunderstorms, while the GFS develops some light SW flow again…..Which would be dry. Either way, temperatures will remain warm here in the high country….
PS. The Euro is the Air Sea coupled model….Would it not be ironic for a summer that was relatively dry to turn wet the last four days of the month of August?…..Labor Day weekend. 😉

A rather cool weekend shaping up as off shore Trofing pushes east through California….A little frost possible in the wind protected valleys, Sunday AM…Warmer early next week ….
Friday August 9, 2019
This Summer has shown to be quite the trough’y one with very low thunderstorm days. Highs in Mammoth have run a good 5 to 6 degrees below normal this Summer. In fact our average warmest day in July is 88 degrees, while 80 was the warmest. We are settling in on a cool breezy weekend as low pressure from the Gulf of AK spreads cooling of some 5 to 7 degrees tomorrow in the high country. Expect highs in the low to mid 60s on Saturday with breezy dry weather. Sunday morning, lows with range in the 30s and 40s. Some cool spots like Devels Post Pile and Tuolumne Meadows may actually drop to the 20s Sunday AM. Some frost is expected…..First taste of Fall?
Expect warmer weather with highs returning to near normal, then cooler the following weekend….Long range models continue the trend of the west coast Trof more often than not in August. this is typically a mild dry pattern with breezy weather in the high country. However, any tropical storm later this month could come into play getting caught up in the upper flow….
