Dry-Down Happening Quickly This Afternoon

The GPS time series for PW estimates at TWC for last five days is shown above. The PW is falling fairly rapidly this afternoon and has dropped below 1.20 inches - down more than a third of an inch since the morning sounding. While some isolated thunderstorms had developed by early afternoon, these have mostly dissipated, and the strong/large storm that was over Miller Peak in the Huachucas has back-built southward into Mexico. The composite radar chart below is from 3:40 pm MST. Things are depressingly quiet and hot here at the house.

However, the NWS has another huge "Short Term Forecast" area issued (see below with its text) for almost all of southeastern Arizona. While these products usually focus in on very specific areas expected to experience significant weather during coming hour or two, there have been a number of similar, very large forecasts issued, when there was little happening, during past few weeks. These seem to be being used as a generic, CYA product, and that is disturbing to me, since lightning flash data, radar, and satellite allow the forecasters to "zoom in" on significant weather, rather than painting things with such a very broad brush approach.

.NOW...
A FEW ISOLATED SHOWERS AND THUNDERSTORMS THIS AFTERNOON.
LOCALIZED RAINFALL AMOUNTS WILL GENERALLY RANGE FROM A TENTH OF
AN INCH TO ONE QUARTER OF AN INCH UNDER THE STRONGER STORMS. SOME
GUSTY WINDS WILL BE POSSIBLE AROUND THE STRONGER STORMS AS WELL.
