The early run of Atmo's high-resolution version of the WRF-GFS model this morning forecasts a complete shutdown of deep convection over Pima County this afternoon. The model forecasted the low-level dry intrusions yesterday (both from west and from south) into southwestern Arizona. Today's run continues the downward trend of 850 mb Td (above) and PW (below), both valid at 5 pm MST. Although a couple of bands of higher moisture remain to the west, the model forecasts no deep convection in the bands.
The forecast skewT for Tucson at 5 pm (below) indicates a deep and dry boundary layer with no CAPE. Westerly winds prevail up to almost 600 mb. It looks like a definite down couple of days for the Tucson area. However, with no rain here at house for 3 days I had to go out and water plants that are in pots yesterday afternoon.
