Mammoth Lakes and Eastern Sierra Weather:
A ridge of high pressure continues to dominate our weather with warm and dry conditions. This strong ridge has brought a NE flow to the area for the last week, bringing with it the mostly clear skies.
As the high has started to move to the east we have returned to an SW to WSW flow and that means haze and at times smoke for the Eastern Sierra over the next week.
Late in the week we have a change in the weather as a trough moving into the Pacific Northwest is forecasted to drop south into Northern California, the effect will be strong SW winds and a Red Flag Warning by the end of the week.
With the Creek Fire 10-12 miles away Mammoth will be on high alert with the higher SW winds in the forecast.
Some of the forecast solutions right now have us getting some rain and the first dusting of snow by late Friday into next Saturday.
The GFS model had been very bullish on moderate amounts of rain and snow, however as of this morning the GFS has now backed off to more reasonable amounts of QPF for this time of year.
The Euro except for a couple runs has been on the drier side of the solution with very light amounts for the Eastern Sierra.
Highs this week have been getting into the lows 70s in Mammoth Lakes with Bishop into the mid-90s. We should see these high drops by 10 degrees in the 4-5 day period. Lows at night will be in the 30s into the 40s for all areas over the next several nights.
