…WINTER WEATHER POSSIBLE ACROSS THE MID-SOUTH…

A FAST MOVING CLIPPER TYPE LOW PRESSURE SYSTEM WILL MOVE ACROSS
THE MID-SOUTH TONIGHT THROUGH SUNDAY FOLLOWED BY MUCH COLDER AIR
AND A POTENT UPPER LEVEL DISTURBANCE SUNDAY NIGHT INTO MONDAY
MORNING.

LIGHT PRECIPITATION SHOULD DEVELOP ACROSS THE MID-SOUTH THIS
EVENING AND CONTINUE INTO SUNDAY MORNING. ACROSS THE MEMPHIS
METRO AREA…A LITTLE SLEET COULD MIX WITH RAIN THIS EVENING
BEFORE CHANGING TO ALL RAIN OVERNIGHT. NO ACCUMULATIONS OF
SLEET ARE EXPECTED. SCATTERED RAIN SHOWERS WILL CONTINUE
THROUGH THE NIGHT AND SUNDAY MORNING. THERE WILL LIKELY BE A
REDUCTION IN PRECIPITATION INTENSITY OR EVEN A BREAK IN
PRECIPITATION FROM LATE SUNDAY MORNING THROUGH THE AFTERNOON
HOURS.

A STRONG COLD FRONT WILL PASS ACROSS THE MID-SOUTH FROM WEST TO
EAST SUNDAY AFTERNOON AND EVENING. MUCH COLDER TEMPERATURES WILL
FILTER ACROSS THE AREA WITH PRECIPITATION BEGINNING AGAIN OR
INCREASING IN INTENSITY BY SUNDAY EVENING AS A STRONG UPPER LEVEL
DISTURBANCE MOVES ACROSS THE AREA. EXPECT RAIN TO QUICKLY CHANGE
TO SNOW SUNDAY EVENING BEFORE TAPERING TO SCATTERED SNOW SHOWERS
BY MONDAY MORNING. THIS SYSTEM HAS THE POTENTIAL TO BRING LIGHT TO
MODERATE SNOW ACCUMULATIONS TO MUCH OF THE MID-SOUTH SUNDAY NIGHT.
THE GREATEST POTENTIAL FOR MODERATE SNOW ACCUMULATIONS WILL REMAIN
ACROSS EASTERN PORTIONS OF THE FORECAST AREA INCLUDING A LARGE
PORTION OF WEST TENNESSEE. ANY SNOW ACCUMULATIONS WILL LIKELY
RESULT IN HAZARDOUS DRIVING CONDITIONS AS TEMPERATURES FALL WELL
BELOW FREEZING AND ROADWAYS BECOME SNOW COVERED SUNDAY NIGHT INTO
PRESIDENTS DAY MORNING.

THERE STILL REMAINS SOME UNCERTAINTY WITH RESPECT TO THE EXACT
TRACK OF THE UPPER LEVEL DISTURBANCE. THIS WILL HAVE A DIRECT
IMPACT UPON EVENTUAL SNOW AMOUNTS… THOUGH AMOUNTS OF 1-2 INCHES
SUNDAY NIGHT ARE POSSIBLE.

PLEASE CONTINUE TO MONITOR THE LATEST FORECASTS FROM THE NATIONAL
WEATHER SERVICE AND MEMPHISWEATHER.NET AND PREPARE NOW FOR POSSIBLE
IMPACTS FROM SNOW. ADDITIONAL WINTER WEATHER ADVISORIES OR WARNINGS
MAY BECOME NECESSARY FOR MUCH OF THE MID-SOUTH FOR SUNDAY NIGHT
INTO MONDAY MORNING.
