Day 3 Convective Outlook

Valid 191200Z - 201200Z

...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
A severe threat is not expected to develop across the continental
U.S. on Tuesday or Tuesday night.

...DISCUSSION...
A mid-level ridge is forecast to build over the central Rockies and
northern High Plains on Tuesday. At the surface, a post-frontal
airmass will likely be located across the upper Mississippi Valley.
Along the southern and western periphery of the post-frontal
airmass, moderate instability is expected to develop by afternoon
from parts of the central Plains eastward into the lower Ohio
Valley. Near the instability axis, a convective cluster appears
likely over part of Kansas Tuesday afternoon. The storms are not
expected to be severe due to weak deep-layer shear and limited
large-scale ascent. Isolated thunderstorms may also develop over
parts of the mid Mississippi and lower Ohio Valleys in the
afternoon. These storms are also not expected to be severe for
similar reasons.
