High Pressure aloft over the far west will continue with light winds…..Warmer than normal temperatures and more often than not…Smoky Skies for Mammoth untill better control is gained over the Creek Fire….
Saturday October 17, 2020
After a decent day yesterday Friday, the smoke rolled in again early this morning with PM 2.5 counts in the hazardous range. There was a wind shift noted at 8:00AM from the north that will improve our air quality for a while this morning. Howver the flow backs from the west again this afternoon and Smoke will once again invade our space. Later tonight some improment expected as dranage winds carry the smoke into the Owens Valley. It will be warmer tody with highs in the low 70s and lows in the mid to upper 30s.
Long Range outlook is dry for the Mammoth area for the next 2 weeks. That does not precloud a system that will bring some cold and snowshowers, the end of the month. It is becoming more clear that this La Nina will result in a drier than normal winter. Split flow pattern will highlight along the west coast south of Oregon. Lots of systems approaching the west coast that will split down the coast. We can get light snow from these systerms. 1 to 6 inches. Also, Lots of Great Basin Lows and snow showers as we go though November toward Thanksgiving. Remember, the MJO will modulate the westerlies and have a greater effect this winter. The Dweebs will be focusing on both the MJO location and strength as well as the AO and EPO. These three teleconnections will be key to longer range or climate outlooks.
