...SIGNIFICANT WINTER STORM POSSIBLE OVER UPPER MICHIGAN LATE
CHRISTMAS EVE THROUGH CHRISTMAS...
A STRONG LOW PRESSURE SYSTEM DEVELOPING OVER THE SOUTHERN PLAINS
ON WEDNESDAY IS EXPECTED TO LIFT TOWARD THE WESTERN GREAT LAKES
LATE THURSDAY INTO CHRISTMAS DAY. THE PROJECTED TRACK OF THE STORM
COULD BRING WET HEAVY SNOW TO MUCH OF UPPER MICHIGAN CHRISTMAS EVE
NIGHT INTO CHRISTMAS DAY. WARMER AIR WRAPPING IN AHEAD OF THE
SYSTEM COULD BRING A MIX OF RAIN AND SNOW TO AREAS EAST OF A LINE
FROM MARQUETTE TO MENOMINEE. CURRENT INDICATIONS ARE THAT THE
PRECIPITATION WILL STAY IN THE FORM OF SNOW OVER FAR WESTERN
UPPER MICHIGAN...WHILE RAIN WOULD MAINLY OCCUR ALONG THE LAKE
MICHIGAN SHORELINE.
DEEP MOISTURE AND COLDER AIR WRAPPING IN BEHIND THE STORM COULD
BRING THE POTENTIAL FOR ADDITIONAL SIGNIFICANT LAKE ENHANCED
SNOWFALL ACROSS WESTERN UPPER MICHIGAN FRIDAY NIGHT INTO THE
HOLIDAY WEEKEND.
SINCE THE EXACT TRACK OF THE LOW PRESSURE SYSTEM REMAINS UNCERTAIN...
IT IS NOT CLEAR YET WHICH AREAS WILL BE IMPACTED WITH THE HEAVIEST
SNOW. HOLIDAY TRAVELERS SHOULD STAY TUNED TO LATER FORECASTS AND
STATEMENTS FROM THE NATIONAL WEATHER SERVICE IN MARQUETTE.
