Interesting forecast Graphics From Art Douglas





First - Top image from Kitt Peak looking south about an hour ago - note the three distinct showers: light right; moderate middle; and heavy left.
---------------------------------------------------
Art sent along the two forecast graphics. The middle image is the NAM model's forecast meteogram for Ft. Huachuca, indicating the strong passage of the backdoor front from the east during early am hours of Wednesday. The bottom is the GFS ensemble members' forecast of the track of Tropical Storm (forecast to become a hurricane by NHC) Frank. So it will be interesting to watch as these two features evolve and affect southeast Arizona during next few days.
