...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Early day thunderstorms are possible across parts of northern Gulf
Coast. No severe thunderstorms are expected.

...Synopsis...
A deep upper low within the broader cyclonic flow regime will move
quickly from the Great Lakes across the Northeast, with secondary
speed max moving southeastward into the mid MS Valley late.
Meanwhile, a weaker upper low will meander about northwest MX, just
east of the West Coast ridge.

At the surface, low pressure will exist coincident with the
aforementioned northeastern low, while high pressure spreads south
across the Plains, and eventually, into the Gulf of Mexico.

...Northern Gulf Coast...
Related to the northeastern trough, a cold front will extend south
from the low, across the Appalachian Front and toward the northern
Gulf Coast where it may be quasi-stationary early this morning.
Showers and elevated thunderstorms may be ongoing at that time, but
will diminish by midday due to strong drying out of the northwest.
Weak instability and poor low-level lapse rates suggest little if
any risk of severe weather.
