You know it’s been a hot first half to summer 2017 in the West but it’s actually been the hottest June 1 through July 11 period on record for Las Vegas, Reno, Phoenix, Tucson and Salt Lake City. With a slightly weaker upper ridge and further east position (Plains), there’s moisture increasing humidity but decreasing […]
Multiple thunderstorm clusters which merge into one large system often spanning 100+ miles during late evening and overnight is known as a mesoscale convective system.

No surprise in the recent early activity when the waters of the MDR (main development region) where warmest on record for the month of […]
Given the intensity of the Southwest heat wave, it should be of no surprise that some southwestern cities recorded their hottest June in recorded history. Meanwhile on the other side of the country, a persistent plume of rich Caribbean moisture directed straight at Florida essentially wiped out Florida’s drought. June’s heavy rains wash away Florida’s […]
