Interesting, the 17Z RUC fields fromm the SPC web page for the HOU area showed between -25 and -100 J/Kg CINH, and about 2000 J/Kg SBCAPE, the 18Z from the same place now shows only 1000 J/Kg and in excess of -100 J/Kg of inhibition.
I doubt it actually became that much more stable between 17Z and 18Z, maybe some new information got into the model.
Because one would suggest storms are likely with a little heating provided any little trigger, and one wouldn't.
Might have to do with ACARS data, automated weather data transmitted by some commercial airliners to the NWS, which, by agreement with the airlines involved, isn't disseminated to the public.
Why would the RUC instability fields change so drastically duing an hour when there was no sensible weather, especially when skies were clearing and the temps were rising. During the preceding three hours, dewpoint has been stable and temps have been rising.
Just curious as to where the data that allows a rapid update model comes from.
