....NO SEVERE THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Isolated lightning strikes could occur today across parts of the
Great Lakes, in association with Lake Effect snowbands.

....DISCUSSION...
Today, an upper-level trough will move from the Eastern Seaboard
into the western Atlantic, as another upper-level trough dives
south-southeastward into the northern Plains. Mid-level flow over
the western U.S. will be mostly from the northwest. At the surface,
a large area of high pressure will remain in place over much of the
southern U.S. into parts of the central U.S. This dry and cool
airmass, which will prevent moisture return making conditions
unfavorable for thunderstorm development across most of the U.S.
today and tonight. The only exception for thunder will be from
northern Lake Michigan southeastward to parts of Lake Erie and Lake
Ontario, where isolated lightning strikes will be possible, in
association with Lake Effect snowbands.
