Valid 111200Z - 161200Z

...DISCUSSION...
A weakening shortwave trough will move from TX across the Southeast
during the Monday/D4 to Tuesday/D5 period, with a weak surface low
moving from the northern Gulf Coast at 12Z Monday/D4 to just off the
Outer Banks of NC by 00Z Wednesday/D6. Given the cool/dry air mass
in place ahead of this system, little if any surface-based
instability is forecast to develop.

For the remainder of the period Wednesday/D6 to Friday/D8, models
show a stable pattern will continue with several days of offshore
flow across the Gulf of Mexico and East Coast. While models disagree
on whether there will be a closed upper low or a large upper trough
over the eastern CONUS, very low heights and strong northwest flow
over the Plains will aid in prolonging the cool and stable pattern.
