Temperature Anomaly GIF: Over the next ten days, we start out HOT then cool off to very warm and return to hot around day 6. Looks like the heat of summer is setting up early. Go to be a long hot summer at this rate, bring your fans if your coming up and staying in one of the Mammoth Lakes Condos you can rent.

*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 during the afternoon and early evening hours. That’s when you can expect SW winds at 10-25 MPH over the high country and wind-prone areas of the Eastern Sierra.

15-Day ECM 500mb Anomaly GIF – Today’s Weather Story: A strong ridge of high pressure will continue to bake the Eastern Sierra with excessive heat warning for Bishop through Friday. Temperatures will remain about 10-15 degrees above average for June through Friday. 

Over the weekend temperatures will back off 5-7 degrees as a weak short wave trough moves through. By next Tuesday the ridge re builds over the area again bringing with hit the next heat wave of Summer.

PS: The Boreal Summer starts on June 1st, that’s way I refer to this time of year Summer and not spring.

*We expect above-average temperatures with a below-average monsoon season for the Summer Weather Season. I am not 100% convinced we will be as dry as models are showing. The good news is we had a big winter followed by an average one, so I don’t expect total smoke or burnout in the Sierra anytime soon.

 Now that it’s June, I’d like to start looking at the ECMWF Seasonal Precipitation Model for next Fall. Below is the run from that model that was released to the public on May 5th. I will post the updated forecast in a couple of days when the next run comes out.
