...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Severe thunderstorms are not forecast today.
...Synopsis...
Water-vapor imagery this morning shows a large-scale upper trough
from James Bay southward through the Great Lakes and TN Valley. The
upper trough will continue to move east and reach the Lower Great
Lakes and East Coast by daybreak Monday. In the low levels, a cold
front will push east of the Carolina coast by early afternoon.
Surface high pressure will influence conditions across the central
and eastern states in wake of the cold front. Weak instability will
yield isolated thunderstorms over parts of the south Florida,
eastern North Carolina, and weak elevated storms over south Texas.
