.DISCUSSION...
AREAS WEST OF JACKSON AND DEKALB COUNTIES IN ALABAMA ARE ALL WELL
BELOW FREEZING AND HAVE EXPERIENCED LIGHT ICE ACCUMULATIONS AND UP
TO AN INCH OR TWO OF SLEET ACCUMULATION OVER THE PAST FEW HOURS. THE
HEAVIEST PRECIP AS OF 15Z IS NOW MAKING ITS WAY EAST THROUGH MADISON
AND MORGAN COUNTIES AND SHOULD BE OUT OF THE AREA COMPLETELY BY 18Z.
THERE IS SOME LINGERING LIGHT PRECIP COMING UP FROM THE SOUTH BUT
AGAIN...IT WILL BE LIGHT AND MAY REMAIN THROUGH THE EARLY AFTERNOON.
14Z LAPS SOUNDINGS IN THE WESTERN AREAS ARE SHOWING THE WARM NOSE
QUICKLY COOLING WHICH MEANS THIS REMAINING PRECIP SHOULD SWITCH TO
LIGHT SNOW IN THE NEXT HOUR OR TWO. LITTLE TO NO ADDITIONAL
ACCUMULATION WOULD BE EXPECTED WITH THIS.

THE UPPER TROUGH IS MOVING THROUGH EASTERN ARKANSAS NOW WHICH IS
HELPING TO QUICKLY PUSH THE PRECIP OUT OF THE AREA. TEMPS ARE STILL
FORECAST TO RISE SLIGHTLY TODAY BUT PROBABLY WILL NOT GET ABOVE
FREEZING IN MOST AREAS.

.PREV DISCUSSION...
/ISSUED 610 AM CST THU MAR 5 2015/
LARGE SWATH OF PRECIP IS MOVING NEWD ACROSS THE LOWER MS VALLEY INTO
THE MID SOUTH/TN VALLEY REGIONS THIS EARLY THU MORNING. MUCH OF THIS
PRECIP IS GRADUALLY BEGINNING TO CHANGEOVER TO A WINTRY MIX OF
FREEZING RAIN/SLEET FOR AREAS ALONG/W OF THE I-65 CORRIDOR...IN THE
WAKE OF A STRONG FRONTAL PASSAGE EARLIER YESTERDAY. LINGERING UPPER
TROUGH AXIS TO THE NW IS HELPING TO DRIVE MUCH OF THIS PRECIP ACROSS
THE SE STATES...WHILE ABUNDANT MOISTURE/STRONG COLD AIR ADVECTION
TRANSLATE INTO A DEVELOPING WINTRY MIX ACROSS THE AREA. A WINTER
STORM WARNING REMAINS IN EFFECT FOR THE ENTIRE FORECAST AREA THROUGH
3 PM THIS AFTERNOON...MAINLY FOR ICE ACCUMULATIONS UP TO ONE QUARTER
OF AN INCH IN SOME LOCATIONS...COUPLED WITH SNOWFALL ACCUMULATIONS
APPROACHING TWO INCHES. LATEST MODEL TIME HEIGHTS THEN SHOW A BRIEF
CLEARING TREND BETWEEN H7-H85 HEADING INTO THE WEEKEND PERIOD. WITH
A STRONG AREA OF HIGH PRESSURE XPCTED TO SETTLE INTO THE SE REGION
SAT/SUN...THE AIR MASS SHOULD BEGIN TO GRADUALLY RECOVER AS HIGH
TEMPS CLIMB BACK INTO THE 50S...WHILE OVERNIGHT LOWS TREND MORE IN
THE 30S GOING INTO THE NEW WORK WEEK.

THE OVERALL WX PATTERN REMAINS FAIRLY QUIET AS THE NEW WORK WEEK
PROGRESSES. HIGH PRESSURE IN PLACE ACROSS THE SE STATES WILL
TRANSLATE EWD INTO THE SRN/MID ATLANTIC BASIN INTO MON...ONLY TO BE
REPLACED BY A SECOND AREA OF HIGH PRESSURE OUT OF THE PLAINS STATES
DIVING SEWD INTO THE MIDWEST/MID SOUTH REGIONS. THE NEXT CHANCE OF
RAIN/SHOWERS LOOK TO RETURN BY TUE...AS DEVELOPING ENERGY ACROSS THE
WRK GULF BECOMES SHEARED FROM THE ERN GULF COAST INTO THE
MID/SOUTHERN ATLANTIC BASIN.
