Cloudy At Sunrise

View looking toward east end of the Catalinas at 6:00 am MST this morning. The low, black smoke at right edge is from the Ventana wildfire, which started after midnight during the early morning hours. The blaze is mostly contained at this time.

Visible satelitte image (below, from 1500 UTC this morning) shows a fairly large cloud mass over southeastern Arizona, that will likely clear-off by mid-day.

Plot of detected CG f;ashes (below, from Atmo and Vaisala) indicates only Arizona storms yesterday afternoon occurred along the far southern, Arizona and New Mexico border.



Elongated, west-east anticyclone remains centered over southern New Mexico this morning (above). The morning sounding from TWC/TUS (below) shows light winds below 300 mb, a deep and dry BL that extends up to almost 500 mb, and essentially no CAPE. The 12 UTC WRF-RR forecast (bottom) shows no precipitation over the metro area through midnight on Sunday night. Only rain here during September has been the 0.01" on the 1st, so things are very dry and I've got to do some watering.
