Mesoscale Discussion 1560
NWS Storm Prediction Center Norman OK
0929 PM CDT Fri Jul 14 2023
Areas affected...Northern IN into southwest Lower MI
Concerning...Severe potential...Watch possible
Valid 150229Z - 150400Z
Probability of Watch Issuance...40 percent
SUMMARY...Some damaging-wind threat may spread eastward late this
evening. Watch issuance is possible.
DISCUSSION...A small bowing segment has recently intensified across
northeast IL, with a 53 kt gust recently observed in Aurora, IL.
Some uptick in storm intensity has also been noted into central IL.
The downstream environment into northern IN and southwest lower MI
is not as unstable, but some low-level moistening from the
southwest, in conjunction with continued support from a midlevel
shortwave trough moving across the Great Lakes, may help to sustain
these storms as they move eastward late this evening.
While nocturnal cooling has commenced, a residual well-mixed
boundary layer resulting from earlier diurnal heating/mixing may
continue to support a threat of locally damaging gusts as storms
spread across northern IN and Lake Michigan into southwest lower MI.
Depending on trends over the next 30-60 minutes, watch issuance is
possible.
