Morning Report From West Side of Tucson

John Diebolt reports: Another, windy and warm night west of the Tucson Mountains with moderate-strong easterly flow keping temperatures way up (89F at 5AM) TD up to 55 degrees by 5AM. With sunrise only a few meager clouds to the distant east..without vertical development. Have noted the airport has had rather stiff SE breeze betwen 10-15 MPH since 153AM but nothing like 24 hours ago. TD is nearly identical but temp is a few degrees warmer there. At the moment (5AM), RUC (from NWS TWC Monsoon tracker page) at 700MB showed TUS area in a bit of a Col with weak NW flow at 500 MB and 300MB with TUS at the northern end of the sharp 300MB trough from the TUS area southwest across central Baja. Sharp 300 MB northerly flow is shown advancing into western Arizona. Seems to agree well with very dry air seen on WV images in that area. Will be interesting to see what the 12Z TWC sounding shows us especially with the weak inversion above 500 MB..barring any bad data. Certainly not the ideal setup for a big day. Another round of mountain-huggers and gusty/dusty/hot in the valleys? (assuming the 500 MB subsidence inversion and dry air aloft does not supress things even more). Will be interesting to see what unfolds!
