Day 2 Convective Outlook
NWS Storm Prediction Center Norman OK
1111 AM CST Tue Dec 12 2017

Valid 131200Z - 141200Z


Thunderstorms are not forecast across the contiguous states on

Broadly cyclonic flow aloft will continue across much of the U.S.
Wednesday, as an upper vortex over the Northeast rotates northward
into Canada, while farther west, short-wave troughing digs southward
across the Rockies.  As a result, overall/broad long-wave troughing
will prevail -- east of the strong ridging residing in the vicinity
of coastal western North America.

With dry/stable continental air to remain in place east of the
Rockies, thunderstorms are not expected.
