1100 AM CST THU NOV 27 2025
AREAS AFFECTED...NORTHERN LOWER MICHIGAN
CONCERNING...HEAVY SNOW
VALID 271700Z - 272200Z
SUMMARY...SNOWFALL RATES OF 1-2 INCH PER HOUR REMAIN POSSIBLE
THROUGH MID/LATE AFTERNOON.
DISCUSSION...A DOMINANT SNOW BAND OFF OF LAKE MICHIGAN, WITH
UPSTREAM CONNECTION TO LAKE SUPERIOR, CONTINUES EARLY THIS AFTERNOON
IN NORTHERN LOWER MICHIGAN. DUAL-POL DATA FROM KAPX SHOWS HIGHER KDP
VALUES WITHIN THIS BAND SUGGESTING 1-2 INCH PER HOUR SNOWFALL RATES
ARE POSSIBLE. GIVEN LIMITED CHANGE IN THE LARGE-SCALE ENVIRONMENT
OVER THE NEXT FEW HOURS, THIS BAND IS EXPECTED TO PERSIST THROUGH
THE AFTERNOON. HIGH-RESOLUTION ENSEMBLE GUIDANCE SUGGESTS THIS AS
WELL. THE MOST INTENSE SNOWFALL RATES WILL LIKELY BEING TO WANE BY
LATE AFTERNOON AS MID-LEVEL ASCENT FROM A SHORTWAVE TROUGH MOVES
AWAY FROM THE REGION. AS THIS OCCURS, THERE MAY BE A SLIGHT
SOUTHWARD WOBBLE IN THE BAND AS 850-700 MB WINDS SUBTLY TAKE ON A
MORE NORTHERLY COMPONENT.
