Weather Pattern has become Decisively Cooler and at times wetter through Months End……La Nina is offically Dead according to the CPC
Sunday May 16, 2021
The Trend is a Weatherman’s Friend and model trends point toward a cooler period over the next few weeks. All models in agreememt in moving the current upper low out of California this Evening while a rather cool airmass keeps unstable air over our area through Monday. Expect both highs and Lows to remain below normal, in the 50s, with the possibility of showers and thunderstorms over the High Sierra into Monday.
Within the medium range, a belt of westerlies approaches the Pacific Northwest and buckels south Wednesday, causing increasing winds in the high country. By Thursday afternoon there is an increasing chance of showers into the night. As is the case this time of the year, upper trofs like to become cut-off, and next weekends long range outlook for the far west will be no exception. This leaves Mammoth Lakes in a cool showery pattern .
Appearently, there are a series of these short wave Trofs dropping in from the GOA that will bring periods of unsettleled weather to the Sierra, possibly through months end. Stay tuned as there will be breaks in between systems. Memorial Weaked is too far to speculate on. However, the pattern seems to want to continue in this fashion.
High temperatures will swing as much as 20 degrees the next 7 days with lows mostly in the upper 20s and 30s.
Climate:
The Climatic Predction Center has offically called La Nina Dead. Let hope it stays that way. We need ENSO to allow the MJO to strongly circumnavigate the globe, for periods of big weather next winter!!
