July 23rd - Finally A Significant Rain Event


Yesterday brought the first widespread rains to our area since the middle of March - the end of a four month local drought. Storms and rain were heaviest here during the morning hours and by early afternoon had diminished to to light showers and sprinkles. Image from campus above shows visibility restricted, probably less than a mile, during the heavy rains. Plot of detected CG flashes below (from Atmo and Vaisala) is for 24-hours ending at 2:00 am MST this morning - a very active day for much of Arizona.




Using rain reports here from both the ALERT network and also from Univ. of Utah's MesoWest. There were many reports over an inch in the north part of the ALERT area - here at house I measured 1.76". Note the 3.62"  and 3.18: amounts west of downtown. MesoWest plot at bottom shows reports for rest of southeast Arizona.



Finally, at end of day, a bit of sun poked through under the high, gray overcast.
