Areas affected...Portions of upper Mississippi Valley
Concerning...Severe potential...Watch unlikely
Valid 072224Z - 080000Z
Probability of Watch Issuance...5 percent
SUMMARY...Isolated marginally severe hail and strong wind gusts are
possible with storms in eastern Iowa, southwestern Wisconsin, and
northwest Illinois.
DISCUSSION...A very narrow warm sector has developed in the upper
Mississippi Valley southeast of an occluded surface cyclone.
Deep-layer shear is quite marginal, but a few semi-organized storms
are possible over the next 1-3 hours. The threat should be short
lived as the storms will likely move into outflow from storms along
the warm front (particularly in Wisconsin). Furthermore, dewpoints
have been mixing out over the last hour. Isolated marginally severe
hail and strong wind gusts will be possible with this activity.
