Morning Sprinkles Here

Heavy clouds over the metro this morning a bit before 8:00 am MST, as cold front moved through. Down at bottom is view of some nice Fall color up in Prescott.

 but wStrong, but moisture-starved trough at 500 mb was west of Tucson this morning (analysis above from SPC) - note the very strong winds with this trough. The 12 UTC morning sounding from TWC/TUS (below - also from SPC) shows the strong, vertical wind profile, with only a shallow layer of saturated air near 700 mb.

Forecast above is from the WRF-GFS run at 06 UTC and is for total precipitation through 5:00 pm this afternoon. Here at house we had very slight sprinkles before the front passed - so a very minimal Trace.

The 06 UTC GEFS plumes for temperature at the airport are shown below - cool today and tomorrow, but then back up into the 80s. October is closing out as a very dry and mild month.
