Satellite Loops Often Tell Story...

One of the things I really enjoyed while I was working was pointing out features, some subtle, some obvious on the various channels (visible, infrared & water vapor) of the GOES Satellite.   For example, today’s vis loop had a  low level cloud swirl over southern Alabama that appeared to enhance showers around it.  There were numerous out flow boundaries surging away from heavy T-Storms from Florida to Louisiana.  Tonight’s IR loop shows what appears to be a mid  to upper level (15-20,000’) circulation that has moved due north of the Tip of the Yucatan into the southern Gulf.   NHC didn’t mention this feature in their discussion and computer models have it going westward into Texas.   However, if this northward motion is real, perhaps that might be a signal that some of the deeper tropical moisture will impact SE Louisiana more than is currently expected.   Only one model (CMC – Canadian) shows any development late Saturday into Sunday.   FOR NOW, it appears the core of the heaviest rains are heading between Corpus & Houston, but that could change.  Texas really needs a good soaking as they have been quite dry.  For us, it appears we’ll stay on the wetter side of this tropical wave and spotty daytime heavy downpours can be expected into early next week before we dry out a little.    


In the Pacific, the remains of Bud are bringing much needed  rainfall into the desert Southwest and that should help contain the many wildfires.    Another weak Tropical Storm (Carlotta) has formed SE of Acapulco so the Pacific remains active while the Atlantic stay quiet.     Unless that upper swirl over the southern Gulf develops (very unlikely), hopefully that quiet trend continues.  Stay tuned!
