A comparison of Suomi NPP VIIRS 0.64 \u00c2\u00b5m visible channel and 11.45 \u00c2\u00b5m IR channel images (above)<\/strong><\/em> showed that widespread thunderstorms had developed on either side of a cold frontal boundary that was moving eastward across Arizona. The Blended Total Precipitable Water (TPW) product (below)<\/strong><\/em> indicated that TPW values were as high as 20 mm or 0.79 inch over much of Arizona, which was in excess of 200% or normal for this time of the year. With unseasonably high moisture in place, these thunderstorms produced a daily record rainfall\u00c2\u00a0 of 0.84 inch at Phoenix, with several locations in the Phoenix area receiving over 1 inch of precipitation (Public Information Statement<\/strong><\/a>). Hail up to 0.5 inch in diameter was reported — in some cases the hail accumulated to the point of totally covering the ground — and winds gusted to 45-55 mph at several locations.<\/p>\n

In addition to heavy rainfall, <\/em>hail, and damaging surface winds, there were several pilot reports of turbulence. Particularly noteworthy were a pilot report of Severe turbulence<\/strong><\/a> at an altitude of 28,000 feet, and a pilot report of Severe to Extreme turbulence<\/strong><\/a> at an altitude of 11,000 feet. Both of these turbulence reports appeared to be associated with convective cells that were growing rapidly, as seen with GOES-13 10.7 \u00c2\u00b5m IR channel images (below; click image to play animation)<\/strong><\/em>.<\/p>\n
