...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
MINNESOTA...NORTHWEST WISCONSIN AND NORTH CAROLINA...
...SUMMARY...
Thunderstorms associated with strong winds and hail will be possible
across parts of Minnesota and northwest Wisconsin on Sunday. Other
storms associated with strong winds will be possible across parts of
central and eastern North Carolina.
...Minnesota/Northwest Wisconsin...
A shortwave trough will move southeastward across the Upper Midwest
on Sunday, as an associated cold front moves eastward from the
Dakotas into western Minnesota. Scattered thunderstorms are forecast
to develop in the early to mid afternoon around a surface low across
northern Minnesota. Additional storms are expected to develop ahead
of the front, southward across eastern Minnesota and northwest
Wisconsin during the late afternoon and early evening. Ahead of the
front, a narrow north-to-south corridor of moderate instability will
likely be in place by afternoon. Within this airmass, forecast
soundings during the late afternoon generally have 0-6 km shear in
the 30 to 35 knot range. This could be enough for isolated severe
storms associated with strong winds and hail.
...Central and Southern North Carolina...
West-southwesterly mid-level flow will be in place across the
eastern U.S. on Sunday. At the surface, a very moist airmass will be
in place across parts of central and eastern North Carolina, where
surface dewpoints should be in the lower to mid 70s F. In response
to surface heating, moderate instability will likely develop across
this airmass by afternoon. Scattered thunderstorms are forecast to
form along pre-existing boundaries or along corridors of enhanced
low-level convergence. The instability co*bined with the very moist
boundary layer may be enough for marginally severe wet downbursts
during the early to mid afternoon.
