Isolated Thunderstorms Yesterday In Cochise County


Visible satellite image from 4:45 pm MST yesterday afternoon shows storms over Cochise County. Some of the Cbs were visible from Tucson also. The heaviest storms occurred on the east side of the Huachuca Mountains - Carr RAWS had 0.68" and Ft. Huachuca had a heavy storm that dropped 0.55" in 15 minutes, along with a gust to 44 mph. The RH during this storm reached only 54%, if the data are reliable (which at times seems questionable for this station). The Rucker RAWS had 0.16" and that was all I could find.


Today PWs are around an inch to 1 1/4 inch across southern Arizona. Winds in the troposphere are again light, and winds above 700 mb have an ominous westerly component. Don't find much CAPE likely this afternoon either. So little to look forward to today except more 100+ heat. The image above is from early Atmo run of WRF-GFS - forecast is total rainfall through midnight tonight. So, model forecasts another mostly down day, as does the morning NWS NAM.
