Mammoth Weather
Brought to you by Howard Sheckter
Weather for the Fishing Opener will be Historic!…..With highs in the mid 70s on Crowley Lake and very light Breezes…..High Temperatures Records in Jeopardy this Weekend
Friday April 26, 2013
Sunday Morning Update:
Clear…cool and calm conditions this morning with chilly early morning lows in the 30s. High temps will bump up to the low 70s in the Towns of Mammoth and June while at Lake Crowley Lake, 79 is the forecast high today Sunday, and 80 is the forecast high Monday. These are record highs for this time of the year…..
For Bishop, 92 and 93 today and tomorrow respectively. Previous records were 90 degrees both days….
Normal high/low temperature this time of the year:
Bishop 75 and 39
Mammoth 58 and 29
Cooler temps will return to the high country Tuesday into Wednesday as a dry cold front moves through. No doubt there will be some with system and high will return to near normal for the Mammoth area…however the Owens Valley will continue with temps above normal, 80s the second half of next week.
The long range forecast keeps above normal temps in the forecast more often than not for the month of May.
The Dweeber……………………………………………………………..:-)
This will be short…..
High Pressure aloft is now building in and the fishing opener looks the best, weather wise historically……
However, there is going to be large diurnal swing in temperatures between the lows at dawn and the highs during the early to mid afternoon. Diurnal swings of 45 degrees are expected, so early morning temps may be near or below freezing while afternoon highs will be in the mid 70s…..
With little or no gradient……expect very light wind if any……..
Enjoy the weekend……Coming off the full moon is usually a late bite for the fishing…..
The Dweeber………….:-)
Another Nice Week….Gusty NE Winds over the Crest Tuesday With 5 to 10 degrees of cooling…..Then Warming Trend Thursday into the Fishing Opener!
Monday April 22, 2013
Temperature Forecast for Crowley Lake for the Fishing Opener:
Saturday Low 30 High 73
Sunday Low 32 High 72
Very Light breezes during the afternoon out of the NNE
Best Fishing Opener weather in Years…..
Full Pink Moon Thursday
Best bite in the late afternoon and evening at or near Full Moon
The Dweeber…………………….Best of Luck…….
Quick Tuesday Update:
Cold Arctic Air has invaded the Northern Plains with some of that chill spilling SW into Northern NV. This has created higher pressure at the surface and a pretty good gradient between North Central NV and the Sierra Crest. Thus NE winds will continue today with cooling as well. Moderate NE winds will gust 40 to 50 over the crest. Moderate winds will occur over the more eastern, north/south valleys of Western NV and Eastern CA Like Owens Valley and Death Valleys today.
The gradient shifts east tomorrow. It will begin to warm up Thursday……A cut off low will allow some build ups Mainly Thursday afternoon. There could be some Virga. Any shower activity will be confined to the Southern Sierra. Highs to day in Mammoth will be back into the 50s with lows tonight in the 20s.
————————————————————————————————————————————————————————————-
Monday will begin like Sunday with light afternoon breezes. Breezes with increase over the crest where NE flow develops as early as late this afternoon and cranks up after midnight tonight. A plunge of cold out of Montana will send another Arctic blast for the Rockies and Upper Midwest. However, for California, it just means that pressures at the surface will build over Nevada and an off shore flow will set up after midnight tonight with light to Moderate Santana winds for the Southern California area Tuesday.
It will be in the mid 60s today in Mammoth with cooler air arriving after midnight tonight. Highs will cool back to the 50s on Tuesday but begin to recover Wednesday into Thursday. There is a little cut off low that will dynamically force some afternoon cloudiness as early as Wednesday PM but more likely Thursday before exiting Friday. Some light showers are possible over the Southern Sierra and South into Southern Ca. The system is too far south to really effect any of the Central Sierra.
Otherwise as promised……the Fishing opener looks fair with above normal temps… (Will fine tune the weekend forecast this Wednesday)
There will be a pattern change the following week as the Eastern Pacific high amps and retrogrades a bit…..More on that later this week. In the meantime enjoy the week ahead…….;-)

Eastern Pacific Upper Ridge Now in Control…….Warming Trend through Sunday……Dry through next Wednesday with some afternoon Build-Ups Midweek…….
Thursday April 18, 2013
Quick Update Friday:
Weak NW slider short wave to kick up a little wind “Over the Crest” late this afternoon into Saturday AM. Then light breezes Saturday afternoon.
CRFC information shows the freezing level going up to near 13,000 this weekend and holding above 12,000 through much of next week. Thus spring thaw will be in progress beginning late this weekend with little change next week. Winds will remain light for the next 5 days and high temps at 8000 feet will move into the 60s by Saturday and remain there for the next 5 to 7 days. Nighttime lows will be coldest over the lower valleys next week with a weak inversion setting up by Sunday. As mentioned yesterday….there is a weak cut off low approaching the Southern Ca coast mid week. This little feature will help to generate afternoon cumulus clouds of the summertime verity. If the pattern lasts a couple of days the air-mass may get modified enough for some diurnal isolated showers. Best day would be Thursday for this.
Although low temps have been in the teens and 20s as of late. As subsidence increases with the upper ridge core building in later next week….early morning lows will move above freezing for many areas with the coldest morning temps below 8000 feet. So expect lows in the 30s beginning Sunday morning at the village then on throughout next week.
At this time…….the Fishing Opener looks great, weather wise!!!
Let the runoff begin!!…………………..>>>

Checking the progress of the pattern change to fair weather…Everything is on track. The upper high at 500mb has pushed the N/S gradient well to the east as the storm that plagued our area with wind, light snow and cold is now focused over the eastern portions of the Midwest, south and into the SE CONUS.
Big story over the far west will be greatly diminished winds the next 24 hours and the warming temps into the weekend. There is a short wave coming over the top of the ridge which axis is still off shore at this time. The short wave will bring some high clouds Friday afternoon and night. At the same time, winds will increase during the mid afternoon Friday on Mammoth Mtn then into the night. Gusts to 50 MPH can be expected later Friday afternoon and night over the crest. Winds will rapidly diminish later Saturday Morning over the higher elevations. Lower elevations will just have some breezes. Through the weekend, temps will rise into the 60s in town and skiing will once again return to Spring type conditions.
Early next week as the off shore upper ridge bodily moves into Ca, height rises will force the upper jet even further to the north. In fact, the core of 130knot upper jet at 300mb is forecasted to be way up in Northern Alberta! At the same time, a closed “anti-cyclone” in the upper ridges core, develops over Central NV.
There is a little feature or small upper cut off low that follows underneath the upper ridge from the pacific that is just off the Southern Ca coast Wednesday. The combination of warm temps, high April Sun Angle and pockets of surface convergence or Upper divergence may kick off the first of Springs air mass afternoon TSRWs Wednesday and Thursday PM a full week away as air mass modification begins for the year 2013!
Overall, the weather looks marvelous this weekend & well into next week.
Next Update….This weekend……
