The model forecasts from last night continue to weaken the northward push of moisture along and east of Continental Divide. The 06 UTC WRF-GFS forecast from Atmo for PW (above on 5.4 km grid - valid at 5:00 pm MST tomorrow afternoon) shows this with best PW returns south and east of the Texas Big Bend country.
The forecast soundings from the same WRF forecast run indicate just a sliver of CAPE tomorrow afternoon and evening for Tucson, with cloud bases between 600 and 500 mb. We may see isolated, very high-base Cbs off to the east tomorrow but there's little chance for anything over the Metro area. Satellite IR image below is from 6:30 am this morning and shows plume of mostly high-level cloudiness coming our way, but main impact likely to be few periods of dreary, thick high and middle cloudiness.
