Mesoscale Discussion 0202

1032 PM CST Sat Mar 05 2022
Areas affected...southern Wisconsin/northern Illinois
Concerning...Severe Thunderstorm Watch 30...
Valid 060432Z - 060600Z
The severe weather threat for Severe Thunderstorm Watch 30
continues.
SUMMARY...Risk for damaging winds, and a brief tornado, continues
across WW 30.
DISCUSSION...Latest radar loop shows a semi-continuous line of
thunderstorms moving east-northeastward at around 50kt across
southern Wisconsin and northern Illinois. The storms remain west of
the Milwaukee and Chicago metro areas, but will affect these areas
within the next hour. While instability continues to gradually
diminish, now at or below 500 J/kg mixed-layer CAPE, very strong
southwesterly flow aloft -- in excess of 60 kt at 1 km and
increasing to 80 kt at mid levels -- will support continued risk for
damaging winds. Observation sites over northern Illinois have
reported gusts in the 55 to 70 kt range in the past half hour, and
expect severe-caliber gusts to affect the Milwaukee area soon, and
portions of the Chicago suburbs shortly thereafter.
