http://www.wunderground.com/severeconvective.asp

A split-flow upper-air pattern will prevail over the Continental U.S. Through
the day one period. The polar branch of westerlies will remain most
progressive...featuring a short-wave trough translating through the
Great Lakes. Meanwhile...a southern-branch trough from the Central
High plains to northwestern Mexico will become increasingly sheared with a
closed circulation eventually forming along its southern extent.


At the surface...a cold front associated with the polar-branch
trough will advance eastward through the remainder of the Great Lakes
with the southwestern extension of the front moving more southeastward toward the Texas
coast.

Showers and a few thunderstorms will remain possible today within the
expansive precipitation shield trailing the surface cold front. 12z
observed soundings within the warm sector revealed poor lapse rates
which will limit instability despite the presence of a relatively
moist boundary layer /I.E. Lowest 100-mb mean mixing ratios of
12-13+ g per kg/. As such...no severe weather is expected.
