Dreary Over Tucson This Morning


Just a quick post this morning. Storms in the distance have produced heavy anvil cloudiness for metro Tucson last several days. View above is from about 6:00 am MST this morning. Bottom two views of Catalinas are both from 4:00 pm - first is from the 2nd and bottom is from the 3rd.


Plot of detected CGs (above from Atmo and Vaisala) is for 24-hours ending at 11:00 pm last night. Basically a large donut hole over eastern Pima County and Pinal County. The Phoenix metro area did have storms last night.

Data from the ALERT network indicated rain at 11 sites around eastern and southern edges of network, and over Catalinas. Amounts were light, except out east along I-10 where the Mescal station received 0.94".

Little storm activity forecasted by 06 UTC WRF-Nam forecast run (which is all I could look at this early morning). Forecast of composite radar echoes below is valid at 11:00 pm tonight. Another day that looks like a tease - one with little chance of measurable rain.
