...NO THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Thunderstorms are not forecast to develop across the U.S. on Tuesday
and Tuesday night.

...DISCUSSION...
A large-scale upper-level trough will dig southeastward into the
east-central U.S. on Tuesday, as an associated surface low deepens
across the Great Lakes. In response, a cold front will move
southeastward across the central U.S. This will reinforce cold and
dry conditions over most of the nation. For this reason,
thunderstorm development is not expected over the continental U.S.
Tuesday and Tuesday night.

Valid 141200Z - 191200Z

...DISCUSSION...
A persistent large-scale upper-level trough is forecast to remain in
the eastern U.S. during the Day 4 to 8 period. This pattern will be
favorable for repeated cold air intrusions into the lower
forty-eight states from mid to late week. Cold and dry surface high
pressure will dominate across much of the nation, making conditions
unfavorable for thunderstorm development.
