Here is an update of the Winter Storm Watch from the National Weather Service...
A WINTER STORM WATCH REMAINS IN EFFECT FROM MONDAY AFTERNOON
THROUGH LATE MONDAY NIGHT.
A DEVELOPING STORM SYSTEM WILL SPREAD A MIX OF WINTRY
PRECIPITATION INTO THE FOUR STATE REGION MONDAY AFTERNOON AND
NIGHT. THE PRECIPITATION IS EXPECTED TO START OUT AS PRIMARILY
SNOW ACROSS SOUTHEAST MISSOURI AND SOUTHERN ILLINOIS MONDAY
AFTERNOON...AND THEN SPREAD OVER THE REMAINDER OF THE AREA BY
MONDAY EVENING.
AS THE APPROACHING LOW PRESSURE SYSTEM DRAWS WARMER AIR
INTO THE LOWER LEVELS OF THE ATMOSPHERE MONDAY NIGHT...SNOW WILL
LIKELY MIX WITH OR CHANGE OVER TO SLEET AND THEN FREEZING RAIN.
MUCH UNCERTAINTY EXISTS IN THE TEMPERATURE FORECAST FOR MONDAY
NIGHT...BUT BY TUESDAY MORNING MOST AREAS WILL BE AT OR ABOVE
FREEZING...BRINGING AN END TO THE ACCUMULATING WINTRY
PRECIPITATION.
A SIGNIFICANT ICING AND HEAVY SNOW EVENT WILL BE POSSIBLE ANYWHERE
WITHIN THE WATCH AREA. THERE IS TOO MUCH UNCERTAINTY TO BE MORE
SPECIFIC AT THIS TIME. HOWEVER...THIS SYSTEM DOES HAVE THE POTENTIAL
TO PRODUCE A SWATH OF 4 TO 6 INCH SNOW FALL AMOUNTS AND ONE QUARTER
TO ONE HALF INCH ICE ACCUMULATION BY DAYBREAK TUESDAY.
