Using the RGB Airmass around DFW

We are setting up in the Dallas/Fort Worth CWA today, and expect some busy weather in a few hours. So, I’ve been scanning the various products to get a general overview. The SPoRT GOES RGB product is good to get a general sense of the airmass structure. Decided to do a second post on it today to start off.

In the image below, the greenish yellow colors represent the more humid subtropical airmass, while the blue to red color is the drier, more continental airmass. You can see the approximate position of the dryline at the interface of these colors. Of course, the sounder is sampling the upper mid levels here (400-500mb) and doesn’t exactly correspond to the surface dryline…you can see this in the overlaid obs. Still, this is a product that can give you a quick idea of the general airmass setup.
