After yesterday's chilly morning low here of 37 F (49 F at TUS), it is a very mild morning today. Current temperature here at 6 am is 52 F and low was only 46 F (airport numbers 62 F and 57 F). Shown above is a 6:00 am MST surface plot from MesoWest (Univ. of Utah) and shown below is the WRF-NAM surface forecast valid at the same time from the 12 UTC forecast run yesterday morning. Appears to have been a pretty good 24-hour hour forecast.
The 06 UTC WRF-NAM forecast from today indicates gusty winds for southeast Arizona and very strong winds up in the northeast third of the state (forecast below is valid at 1:00 pm this afternoon). Tomorrow the forecast indicates that strongest winds shift eastward into Santa Cruz and Cochise Counties and new Mexico.
Hurricane Sandra (above at 5:00 am MST) is forecast by the NHC (below) to become a major hurricane, before turning northeastward and heading into Mexico.
The main precipitation over the weekend (above is 06 UTC WRF-GFS forecast of accumulated precipitation through 5:00 PM next Sunday) is forecast to occur over the mountain ranges of the Inter-mountain West. Hurricane Sandra produces major rains over western Mexico, and the moisture plume from Sandra contributes to a very major rain event over the Southern Plains. Flash Flood watches are already in effect for parts of Oklahoma and Texas for Friday and Saturday.
