THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF SOUTHEAST
MICHIGAN.
.DAY ONE...TODAY AND TONIGHT
SNOW ACCUMULATION WILL AMOUNT TO ABOUT AN INCH AROUND SOUTHEAST

WILL BE IN THE TRI CITIES AND NORTHERN THUMB WHERE A TRACE TO LESS
THAN AN INCH IS EXPECTED.
A WEAK BUT SLOW MOVING LOW PRESSURE SYSTEM WILL MOVE THROUGH THE
OHIO VALLEY TODAY. SINCE THE SYSTEM HAS ADEQUATE MOISTURE, THE SLOW
MOVEMENT WILL ALLOW SOME LIGHT ACCUMULATION TO OCCUR DESPITE THE
WEAK NATURE OF THE SYSTEM AND RELATIVELY WARM SURFACE TEMPERATURE.
THE PATTERN OF SNOW WILL WEAKEN AND MOVE EAST DURING THE MID
AFTERNOON.
.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY
A CLIPPER SYSTEM WILL AFFECT SOUTHEASTERN MICHIGAN LATE SUNDAY
NIGHT AND MONDAY. SNOWFALL ACCUMULATIONS OF 1 TO 2 INCHES WILL BE
POSSIBLE FOR MOST AREAS. THE BETTER POTENTIAL FOR SNOWFALL
ACCUMULATIONS EXISTS ALONG A LINE FROM THE TRI CITIES
SOUTHEASTWARD TO MACOMB AND ST CLAIR COUNTIES.
