Areas affected...parts of eastern MN and northwestern WI

Concerning...Severe potential...Watch unlikely=20

Valid 032007Z - 032200Z

Probability of Watch Issuance...20 percent

SUMMARY...A few damaging gusts are possible this afternoon across
portions of eastern Minnesota and northwestern Wisconsin. A watch is
not anticipated.

DISCUSSION...Convection has developed along a cold front stretching
across eastern Minnesota. Ahead of the front, mixing has driven
temperatures to near 90 F with dewpoints in the mid 60s F, yielding
MLCAPE values near 1500-2000 J/kg. Given the linear forcing from the
cold front and weak low-level and deep-layer shear, upscale growth
into a loosely organized QLCS is expected, and consolidating cold
pools may produce a wind damage threat. The northern portion of the
line will soon move over Lake Superior, and there is some
uncertainty as to how much the cooler air over the lake will weaken
the line. The remainder of the line is expected to progress eastward
with time and weaken this evening with the loss of daytime heating.
