Valid 191200Z - 201200Z

....NO SEVERE THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Thunderstorms are expected to develop on Monday in parts of
south-central and east Texas, with storms moving eastward to the
central Gulf coast by Monday night. No severe threat is expected.

....DISCUSSION...
An upper-level ridge will approach the East Coast on Monday, as a
shortwave trough moves through the Great Plains. Ahead of the
trough, flow at mid-levels will be from the west-southwest across
much of the Gulf Coast region. A low-level jet is forecast to move
onshore into southeast Texas around daybreak on Monday. Elevated
thunderstorm development is expected near the low-level jet during
the day in parts of east Texas and Louisiana. As this feature moves
eastward, thunderstorm potential will increase in the lower
Mississippi Valley and central Gulf Coast from the evening into the
overnight. Surface dewpoints are forecast to remain below 60 F in
most areas along the Gulf coast, suggesting that instability will
remain weak on Monday and Monday night. For this reason, a severe
threat is not expected to develop.
