Unsettled Morning


Heavy clouds coming off the Catalinas over the west side of the metro area this morning. Low-level dust is from the storm west of I-10 yesterday afternoon. There were a few sprinkles here around 7:00 am, and perhaps enough to wet ground to our west.

Strong winds after midnight this early morning brought gusts to 67 mph at Ft. Huachuca and 59 mph at Pioneer Airfield. Gusts of 30 to 40 mph were common over southeast Arizona.


Morning 500 mb analysis (above) shows intense, 500 mb closed- low over southwestern Utah, with very strong winds to its west, south, and east. This system is forecast to elect very rapidly to the northeast, reaching Colorado by evening - bringing winter storm conditions across the higher elevations and also Wyoming. Surface map (below) from about 7:30 am MST shows heavy snow currently impacting parts of Utah. Cold fron is moving into western New Mexico and Colorado.

Images at bottom show a skiff of snow on the ground at Flagstaff this morning and heavy rains in Globe before sunrise. All-in-all quite a wintry change from the past week!
