...DISCUSSION...
Strong surface high pressure over the central U.S. and a prior cold
front intruding into the southern Gulf of Mexico will result in a
dearth of boundary layer moisture across much of the CONUS through
at least Day 6/Sun. As a result, thunderstorm chances will be low.
Toward the end of the period, some forecast guidance suggests lee
troughing will allow southeasterly low-level flow to bring modest
Gulf moisture northward across TX. This may result in some increased
thunderstorm chances across south/central TX on Day 7-8/Mon-Tue.
However, severe-thunderstorm potential will remain low during the
Day 4-8 time frame.
