Mesoscale Discussion 1522
NWS Storm Prediction Center Norman OK
0138 PM CDT Wed Jul 20 2022
Areas affected...southeastern Lower Michigan and into northwestern
Ohio
Concerning...Severe Thunderstorm Watch 477...
Valid 201838Z - 202015Z
The severe weather threat for Severe Thunderstorm Watch 477
continues.
SUMMARY...Severe risk continues across valid portions of WW 477 --
particularly from the Thumb area of Lower Michigan southward to
northwestern Ohio.
DISCUSSION...Latest radar loop shows thunderstorms ongoing from
northern portions of Lower Michigan southward to the
Michigan/northwestern Ohio border. The strongest storms are ongoing
from the Thumb area southward to near Pontiac, moving
east-northeastward at around 35 kt. These storms are ongoing just
ahead of the advancing cold front, in an area of maximized
mixed-layer CAPE (1500 to 2500 J/kg), and 0-6km shear roughly 40 kt
per the latest KDTX VWP, and recent 18Z RAOB. Storms will move into
Lake Huron over the next hour or so, but will remain capable of
producing locally strong/damaging gusts in the mean time. In
addition, southward expansion of the broken band of storms may occur
across parts of northwestern Ohio in the next 1 to 2 hours.
