Tuesday AM Update:

Looking down the road….

Here is an outlook for the next two weeks…..

The Positive height anomaly in the Gulf of AK is forecasted to very slowly retrograde westward toward 160west over the next 2 weeks. Through the process, Upper troughing seems to have found a new home and so the clash of the air-masses  between the west coast trof and the heat over the Great Basin will dominate our local weather for sometime to come.  This is a typical spring pattern of dryness and often times breezy weather for Mammoth Lakes with little hope of precipitation other then a few isolated convective thunderstorms on rare occasions. There will be Lake Wind Advisories  from time to time so if your boat fishing on area lakes, be sure to check with the latest forecast for Afternoon winds before going out each morning….The pattern appears to be supported by the MJO in Phase Space 2 for May/June. So be ready for a persistent breezy pattern that will be with us more often than not for the next week or two……….

In time….Heights will rise and temps recover back into the 70s…but not until closer to mid June.

Next Update this Weekend……………………….

Our warm up peaked Sunday with a high temperatures of 75 degrees in the Town of Mammoth……Both Monday and Tuesday will be about 74. The upper ridge weakens and will eventually give way to troughing along the West Coast by mid-week. This time of the year, troughing usually brings normal to below normal temperatures….with notably breezy weather. Occasionally, an upper trof will reload with a stronger short wave that will cut off a low in the bottom of the long wave trof. Whether that happens or not it will not be until the end of this week. A cut off low if far enough south can give us a thunderstorm pattern over the sierra. So far the models keep this feature too far to the north next weekend….So only a slight chance is warranted.

In the meantime, high temps will remain in the mid 70s through Tuesday, then a slow cool down will take place through the end of the week.   High temperatures will cool nearly 15 degrees to near 60 by next Sunday.  It will be a breezy week in Mammoth. SW winds will blow most afternoons with stronger breezes that will blow through the night and stronger winds yet on Wednesday approaching 40 to 45 MPH in town and gusts to 65 over the crest.  This is all part of a pattern that is being influenced by the developing El Nino that will keep our weather quite breezy at times going into the Summer.
