Mammoth Mountain Weather Forecast from the Snowman

Mammoth Mountain & Eastern Sierra Recreational Weather
May 28th, 2024 @ 9 AM – The forecast for the upcoming week will be highlighted by a progressive ridge of high pressure moving east of the area by midweek. A few degrees of cooling could occur midweek, with the build-ups looking to dissipate by Wednesday.
By late in the week, more ridging and higher heights were moving into the area, leading to some warm, early Summer-like temperatures, possibly more build-ups, and a very slight chance of a shower.
For those planning on going out in the area for some fun, here are the fine weather details on what to expect.
There will be a 20-30% chance of thunderstorms in the High Country over the next couple of days, with clear skies expected on Wednesday. By Thursday and Friday, there will be a 10-20% chance of build-ups and a few raindrops possible.
Temperatures at the 9000-foot level (Main Lodge / Lake Mary) will start the week in the low 60s, rising into the mid-60s by Thursday and Friday. Winds on Mammoth Mountain and over the higher elevations will be SW into Sunday at 5-15 MPH, with gusts up to 20 – 30 MPH at times.
Temperatures for Mammoth Lakes will range from the low to mid-60s, with some warming next Sunday into Monday.
Skies will be mostly clear this week in lower elevations, with just a few clouds spilling down from the High Country. Temperatures from Crowley Lake to Toms Place will be in the low to mid-70s, with nighttime lows in the low to mid-40s.
For Bishop to Mill Pond, Summer is on, with temperatures in the upper 80s to the lower 90s except this week. Midday temperatures could even warm a bit more by next weekend. Nighttime lows will be in the low to mid-50s. *If you plan to hike or Mountain Bike near Bishop and Mill Pond, plan to get out during the morning hours and be in by noon.
Winds from Crowley Lake to Bishop will be 5-10 MPH. Afternoon winds in the Bishop area will gust 15-20 MPH at times.

MSLP GIF out 6 Days – Not much going on weather wise. THere is a chance of some T Storms on Tuesday and then mostly clear weather looks to be in place for the rest of the week. By the weekend a big warm up is expected.
MSLP = The mean sea-level pressure (MSLP) is the atmospheric pressure at the mean sea level. This is the atmospheric pressure normally given in weather reports on radio, television, and newspapers or on the Internet.
Temperature Anomaly GIF –All we see on the model run below is warm to hot days ahead. There was a great run on cooler weather, but all that is behind us now until we get past Summer. Enjoy the warmer times while you can as mid Fall into the upcoming Winter are looking cooler than average.
*The term temperature anomaly means a departure from a reference value or long-term average. A positive anomaly indicates that the observed temperature was warmer than the reference value, while a negative anomaly indicates that the observed temperature was cooler than the reference value.
The Wind Forecast GIF – Looking at the National Blend of Models wind forecast. Wind speeds over the next week will be gusty at times during the afternoon hours. That when you can expect SW winds at 10-25 MPH over the high country and wind prone areas of the Eastern Sierra.
QPF Forecast Image – The qpf showing up here is for today 5/28, after that the models are dry for several days.
15-Day ECM 500mb Anomaly GiF – Higher heights with 2 different strong ridges of high pressure are showing up on the run below. The period of June 8th – the 11th is looking possibly HOT for the Eastern Sierra.
Confidence in a heat wave is growing as models all seem to show this solution. The good news is the longer range outlook as the area warm not HOT after about the 11th of June.
*For the Summer Weather Season we expect above average temperatures with a below average monsoon season. I am not 100% convinced we will be as dry as models are showing right now. The good news is we had a big winter followed by an average one so I don’t expect a total smoke or burn out in the Sierra anytime soon. 🙂

* Mammoth Mountain and Eastern Sierra Weather is updated several times a week by local Steve Taylor. The goal is to provide detailed weather forecasts presented in an easy-to-read format. This isn’t a Hype, one-and-done model-run website. It’s just the basic facts from how I see it after 40 years of being involved in the local weather and recreation. And yes, I use Weather Bell for my forecasting data.

Author – Steve Taylor – The Mammoth Snowman – Over the last 30+ years, Snowman has spent countless hours studying and learning about Mammoth Mountain Weather and Snow Conditions first hand. He has been skiing around the hill with marked ski poles since March of 1991 so he can measure the fresh snowfall amounts out on the hill.
Snowman started blogging this information back in 1990 on the old Mammoth BBS system, then the RSN Forums and then on to MammothSnowman.com in 2004 with Video & Photo Blog reports. (No YouTube back then). Facebook got added to the fold back in 2008 and then the Facebook Group in 2016.
Reports, videos, and photos from the website have been featured on both local TV Stations here in Mammoth and Bishop, along with KTLA, AP, Fox, ABC, CBS, and NBC News.
