First of all:
"ROUGHLY FROM A TPL TO GGG LINE" What's "TPL" and "GGG?"
"PW VALUES WILL GRADUALLY FALL DURING THE DAY" I'm sure P must be for precipitation. So what's the "W" stand for?
And finally, "POPS"?
PW = Precipitable Water, a measurement of how much moisture could be "squeezed" out of a given column of air
POPS = Probability of Precipitation (the plural form)
TPL = Temple, TX (near Waco)
GGG = Longview, TX - northeast part of the state.
=============================================
Now, as for the disturbance, take a look at the westward extent of the Bermuda high at the surface and 850 mb. That would be just west of the Florida Peninsula. Lower-level wind flow is just about straight to the north from the disturbance. There's an upper-level trof across the NW Gulf.
Since that upper-level trof is forecast to build a bit eastward with time, and the Bermuda high doesn't build west, I don't see any reason for this thing to go any farther west than it already is. That means it would most likely head north right into Florida. The chances of it developing into a TD or TS are still not too great, maybe 20-30%. Looks like a rain-maker.
