Some Thunderstorms This Afternoon

There have been some thunderstorms around southeast Arizona during the last couple of hours, in addition to some very light sprinkle showers. Radar above is composite image for about 05:00 pm MST and graphic below shows CG flash density during the past two hours (from and Vaisala).  I also have noted that the hourly digital forecast for TUS have gone considerably awry during the afternoon hours today, as the temp trends downward and wind shifts occurred considerable earlier than the models forecast. Very welcome change to cooler and higher RH conditions today.
