WY2016 Storm 55

I. Welcome Storm 55

Storm 55 is a typically medium-sized follow-up storm to a major storm. It’s colder, so skiers should love the more powdery snow. The Kern county mountains are on watch, the Sierra Nevada on warning. Looks like a good Sierra snow-maker.

III. Storm Totals

55.)) Storm 55 was a compact upper level low and cold front – classic comma-shaped storm. First the low came ashore on 160306, then the comma of the cold
front whipped south all day 160307, spreading a single solid wave of rain through NorCal and CenCal. Then the upper level low, its cyclonic core pounded south and exited via Arizona/Sonora, bringing hours of squall lines to the southland. Mountain snow and
rain lingered and then blew out by midday 160308. Heavy Bay Area rain added to wet soil, causing a mountain to collapse under a commuter train, derailing it. Storm 55 was a strong storm, dropping 39.88 inches of rain on the 65 sampler cities, about .61 of an inch per city. Storm 55 shared part of Sunday with Storm 54, which the reason for the subtraction column. By midday Tuesday, Storm 55 was over and on the NorCal coast Storm 56 had begun, hence why Tuesday is split into two half-days.
