A Closed upper low was located at 44N/137W this morning indicating little if any movement over the past 24 hours. This will insure one more very nice day for the Mammoth area. While the off-shore closed low is waiting for the upstream bump of the next system, The fail weather upper high is centered east of our area….thus winds will continue to be moderate over the crest today. Do not expect windless mountain weather if your skiing/boarding the upper elevations. Temps will range in the 40s over the upper elevations of Mammoth Mt to the upper 50s today here near the Village at Mammoth.
Current Sat loop shows moisture streaming NEward on the eastern side of the upper low. PW according to AMSU imagery is about an inch off the coast of Northern Ca.
What we are dealing with are really two distinct systems here. The second system by far is the strongest for the central sierra as the upper jet comes into California in the “sweet spot” just north of Pt Conception. So the Front Left Divergent portion directly effect the Central Sierra, according to the new Monday 12z GFS. Yesterdays EC painted up to 2 inches of QPF over the Central Sierra. Friday, HPC is more in line with 1.5 inches.. All this of course comes after the initial shot Wednesday of 1 inch + by Thursday AM. So this may be a productive week in dumping a good 3 feet over the upper elevations. This of course is good news as the winter so far is about 50% of normal here at Mammoth Pass.
