MD 0127 CONCERNING SNOW SQUALL FOR NORTHERN MICHIGAN
Mesoscale Discussion 0127
NWS Storm Prediction Center Norman OK
1136 AM CST Thu Feb 02 2023
Areas affected...Northern Michigan
Concerning...Snow Squall
Valid 021736Z - 021930Z
SUMMARY...A snow squall is moving southeast across northern Michigan
early this afternoon.
DISCUSSION...Convergence is strengthening along a cold front as it
moves southeast across northern Michigan and southern Ontario. As a
result, a line of higher reflectivity has appeared within a broader
area of moderate snow across northern Michigan. A broad wind field
is present with 15 to 20 mph winds and gusts 25 to 30 mph. However,
within this line, KAPX velocity data shows wind speeds approaching
35 knots. This corresponds well to RAP forecast soundings which show
mixing to around 2km where winds are near 50 knots and boundary
layer maximum winds are around 30-35 knots. Therefore, in addition
to the heavy snow, expect the convective line to contain wind gusts
up to 40 mph. This will likely result in reduced visibility,
potentially below 1/4 mile, and the potential for whiteout
conditions.
