Mammoth Weather Outlook
One more slider system to bring showers tonight while upper ridge builds in Wednesday and Thursday……Fair and warm St Patty’s Day……Then beware of the ides of March…..
Tuesday March 12, 2019
Thursday PM
Quite weather pattern to continue through Monday with highs climbing to the low 50s by Sunday and Monday, lows at night will in the teens then 20s late weekend….
Pattern next week looks wimpy compared to the storms of February. Nevertheless, mainly light to moderate precipitation is expected Tuesday night into Wednesday. There is a bit of a challenge for Wednesday as on of the models splits the trof coming in during the morning period. If that becomes mainstream thinking, we could end up with a lot less. Best guess now is 6 to 12 inches above 8000 feet. The snow level should range between as high as 7500 ir 8,000, down to about 6500 feet. There is another system that looks similar the following weekend. Remember, this is just an outlook, more details will come over the weekend and early next week…. In the meantime, have a happy and safe St Patties Day Sunday……..a big pot of Corn Beef, Cabbage and Carrots with a splash of Jameson one of my favorites.

The Storm system that brought the chill and the light snow over the weekend was rapidly opening into a trof and accelerating eastward through the deserts and Northern Mexico this afternoon. On its heals was the last short wave in the form of an inside slider. This system will bring another shot of cooling later tonight and Wednesday as well as a brief shot of light snow showers this evening. It has a good gradient as well, so expect wind. Highs will be in the low 30s once again Wednesday.
As promised, the weekend looks much milder. There will be some cloudiness at times, however highs will climb toward 50 by Sunday and Monday.
There is another pattern shift next week. The upper high that builds over the weekend will amplify up into Western Canada. This forces the undercutting of the westerlies back into California. Being that it is Mid March, and the MJO is not strongly favoring areas of the phase space that would support an AR, the outlook is clouded, no pun intended. The CPC has the central and north Central CA wet mid-week, next week. The models struggle with a weak extension of the east asian jet into the central west coast by mid-week. However, I will say that this time, there is no phasing with any cold Trof. So, if we get a storm, the snow level may end up higher with any storm track that develops. In any case, It is too soon to know any details…..Better visibility by the weekend.
