...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe storms are not anticipated on Tuesday.

...Synopsis...
Broad cyclonic flow aloft will continue to overspread the eastern
U.S. as upper ridging remains in place west of the Rockies. Guidance
consensus depicts a pronounced, positively-tilted mid-level trough
rapidly amplifying while quickly translating southeastward, pivoting
around the broader cyclonic flow aloft. As a result, a cold front
will begin surge southward across the northern Plains on Tuesday.
Farther to the south, rich low-level moisture will continue to
meander across the central and southern Plains into the Lower MS
Valley. Strong thunderstorms could occur along/ahead of the surface
cold front over the northern Plains, where modest tropospheric lapse
rates and vertical wind shear would support strong wind gusts.
Similarly, a couple of thunderstorms with strong wind gusts cannot
be ruled out over the Lower MS Valley, where a passing mid-level
perturbation may locally augment deep-layer shear to support
multicellular structures. Nonetheless, the anticipated coverage of
severe wind or hail appears too low for the introduction of severe
probabilities this outlook.
