Areas affected...west-central Wisconsin
Concerning...Severe Thunderstorm Watch 429...
Valid 180129Z - 180230Z
The severe weather threat for Severe Thunderstorm Watch 429
continues.
SUMMARY...Thunderstorms capable of instances of strong to severe
wind will continue eastward this evening.
DISCUSSION...A line of thunderstorms ongoing from central WI into
far southeastern MN and northeastern IA will continue to pose some
risk of strong to severe wind. Confidence in downstream risk beyond
WW429 remains uncertain. The downstream environment is moist and
unstable, with dewpoints in the mid 70s and MLCAPE around 2000 J/kg.
Should storms be able to develop a strong cold pool and become
better organized within this regime, the risk for damaging wind may
continue past WW429. Thus far, this line has remained sub-severe,
with strongest reflectivity located mostly well behind its own
outflow, but trends will be monitored. A downstream watch is
unlikely at this time.
