MD 0552 CONCERNING HEAVY SNOW FOR PORTIONS OF NORTHERN WISCONSIN AND LAKE SUPERIOR
Mesoscale Discussion 0552
NWS Storm Prediction Center Norman OK
0125 PM CDT Mon Apr 17 2023
Areas affected...Portions of northern Wisconsin and Lake Superior
Concerning...Heavy snow
Valid 171825Z - 172130Z
SUMMARY...Heavy snowfall with rates 1-2 inches per hour expected to
continue through late afternoon.
DISCUSSION...A band of moderate to heavy snow continues across
portions of Lake Superior and northern Wisconsin behind a strong
surface low and evident TROWAL. Northwesterly flow across Lake
Superior has led to a band of locally very heavy snow, with
mesoscale enhancement from moisture fetch across the lake and
upslope flow. 1.5-2"/hr rates have been observed within this bad.
Hi-res ensemble guidance indicates that 1-2"/hr rates could continue
over the next couple of hours. Expect quick accumulations with
periods of reduced visibility, as winds gusts up to 25-30 mph are
also being observed.
