Areas affected...portions of southeast MN into north-central WI
Concerning...Severe potential...Watch possible=20
Valid 231954Z - 232200Z
Probability of Watch Issuance...60 percent
SUMMARY...Intensifying thunderstorms may pose a risk of damaging
wind gusts across southeast Minnesota into portions of
northern/central Wisconsin the next few hours. Area is being
monitored for possible watch issuance.
DISCUSSION...Isolated to scattered thunderstorms are
developing/intensifying this afternoon along/just ahead of the southward-advancing cold front. This activity is tracking along a
differential heating zone and within the strong instability gradient
oriented across north-central WI. Strong heating ahead of these
storms and dewpoints in the mid 70s have allowed inhibition to
weaken. This area is on the edges of more favorable deep shear, but
20-30 kt effective shear magnitudes may be sufficient for organized clusters/small bows given strong instability. Modified RAP forecast
soundings and regional VWP data show somewhat small but favorably
curved low-level hodographs. Low-level shear will remain modest, but
given the very moist and unstable boundary layer, a tornado or two
also could occur, in addition to damaging wind gusts. This area is
being monitored for possible watch issuance.
