...NO THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Thunderstorm probabilities are negligible on Thursday.

...Discussion...
A quiescent pattern for thunderstorm activity will envelop much of
the CONUS tomorrow. Two areas of sub-10 percent thunderstorm
probabilities remain apparent. 

An Arctic air mass will settle into the Upper Great Lakes.
Downstream, lake-effect snow bands will persist with the most
organized one expected in the lee of eastern Lake Ontario. A few
lightning flashes are possible during the period of maximum snow
rate intensity, seemingly from late afternoon into Thursday night.

A couple elevated thunderstorms could develop over a portion of the
Desert Southwest from southeast CA to the Lower CO Valley ahead of
an approaching shortwave trough. Despite strong forcing for ascent,
buoyancy appears minimal with MUCAPE likely holding sub-100 J/kg.
