Early Morning Update

Edited to add - 7 am MST web cam views of Kitt Peak (above) in the clouds and of Catalinas (below) with heavy, low clouds. Morning sounding shows a shallow cloud layer from about 800 to 700 mb. Morning walk was easier on my return with west wind at my back.

As the closed, 500 mb low moves into northwest Arizona, thunderstorms have returned to northeastern parts of the state. Graphic above shows lightning strikes during the six hours ending at 4 am this morning (10 October). Surface plot below is from 5 am and shows thunder, rain, and snow from northeastern Arizona into Utah and western Colorado. The Pacific cold front is just moving across eastern Pima County and at 5 am only 2 ALERT stations up in the Catalinas had reported precipitation.
