Monsoon 2009 - Update #1

Yesterday, SoCal's deserts experienced classic monsoon conditions with several organized MCS-type thunderstorm complexes that raced out of western AZ near Yuma, and moved northwestward into the western Mojave Desert around Edwards AFB. The Edwards storm complex even went severe warned during the afternoon around 3pm local time.
Additional activity fired along the Sierra Nevada range as far north as Reno, as well as a few isolated cells in the southern San Joaquin Valley.
