Mammoth Mountain to Bishop Weather Forecast

Today into Monday, a ridge of high pressure will be building over the area, creating a short-lived heat wave with temperatures by Monday around 4-7 degrees above average.
The ridge lingers into late Tuesday before some weak troughing sets up and lower temperatures to around average by next Thursday.
Kinda shocking to see this pattern after so many very hot Julys the last few years. For now, the four corners high-pressure system is off the table for at least the next 10 days.
After that time frame, the ECMWF ENS wants to set up the four corners high-pressure system. Once that happens (if it does), then the area will warm up again, and at some point, the chance for weak Thunderstorms will return.
As of now, I see no signs of any monsoonal flow moving into the Sierra. Hopefully, at some point, we can see some longer-duration thunderstorms with lots and lots of rain.Â
For now, expect dry conditions with low humidity levels and stage 1 fire restrictions in place.
Air quality remains good in the area, but we’re starting to see some hazy skies today. The Purple Air shows hazy skies at times over the next couple of days, but nothing that should create any concern.Â
