A storm stalled over Las Vegas, producing an hour of hail that accumulated to 4-6 inches deep in much of the city.
A supercell storm produced a swath of deep hail accumulations north and east of Wagon Mound, reported as deep as a foot but 4-5 inches was the deepest I saw, with some of the stones up to 1.5" in diameter.
Although this stone was about 2.5" in diameter, I saw others along the road that were 4". There were spotter reports of up to 4.75" hail with this storm.
The most interesting aspect of this storm is that it occurred in a wintry setting - the same convective cell that produced this up to quarter-sized hail also produced snow and graupel (snow pellets), with the surface temperature ranging from the upper 30s to lower 40s. This cell and other nearby cells, which also produced copious quantities of graupel, snow, and possibly hail, occurred at the end of an intermittent 2-day winter storm that earlier produced a few inches of snow in the valleys and upwards of a foot and a half in the mountains.
