THIS HAZARDOUS WEATHER OUTLOOK IS FOR A LARGE PART OF ARKANSAS.

.DAY ONE...TONIGHT

COLD AIR IN THE WAKE OF THE FRONT THAT MOVED THROUGH THE STATE
THURSDAY HAS OVERSPREAD THE NATURAL STATE AND OUR FIRST WIDESPREAD
WINTER WEATHER EVENT OF THIS SEASON IS WELL UNDERWAY AND WILL ONLY
INCREASE THROUGH THE NIGHT.

MOISTURE CONTINUES TO SURGE INTO THE STATE AND WILL CONTINUE TO
OVERRUN THE COLD AIR NEAR THE GROUND. THE COLD AIR IS NOT VERY DEEP
IN CENTRAL AND SOUTHERN SECTIONS OF THE STATE. LIGHT RAIN WILL
DEVELOP AREA WIDE WHICH WILL BE MIXED WITH SLEET AT TIMES. AS
TEMPERATURES DROP...THE RESULTANT. WINTER PRECIPITATION WILL BE A
MIX OF FREEZING RAIN AND SLEET. ACROSS THE NORTH WHERE THE COLD AIR
IS MUCH DEEPER...FREEZING RAIN AND SLEET WILL SLOWLY TRANSITION TO
SNOW DURING THE NIGHT.

AS A RESULT...A SNOW ADVISORY IS IN EFFECT FOR NORTHERN ARKANSAS
TONIGHT WHILE WINTER WEATHER ADVISORIES ARE IN EFFECT ELSEWHERE.
THERE IS A POTENTIAL FOR SIGNIFICANT ICE ACCUMULATIONS IN CENTRAL
AND SOUTHERN ARKANSAS AND A MIXTURE OF ICE AND SNOW ACCUMULATIONS IN
THE NORTH. HAZARDOUS TRAVEL IS LIKELY IN THE NORTH AND POSSIBLE
ELSEWHERE.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY

COLDER AIR WILL CONTINUE TO MOVE INTO ARKANSAS ON SATURDAY WHILE
MAINLY LIGHT PRECIPITATION FALLS ON THE STATE. THE SAME MIXED BAG OF
WINTRY PRECIPITATION IS EXPECTED ACROSS CENTRAL AND SOUTHERN
SECTIONS OF THE STATE WITH SNOW CONTINUING TO BE LIKELY IN THE
NORTH. SOME OF THAT SNOW WILL LIKELY REACH INTO CENTRAL PARTS OF
ARKANSAS ON SATURDAY...INCLUDING THE LITTLE ROCK METROPOLITAN AREA.
DRIVING CONDITIONS ARE EXPECTED TO BE TREACHEROUS...ESPECIALLY ON
BRIDGES AND OTHER ELEVATED ROADWAYS.

FREEZING RAIN AND SLEET WILL CONTINUE ACROSS THE SOUTHERN AND
CENTRAL SECTIONS WITH LIGHT SNOW OVER THE NORTH. THE MAIN SURGE OF
MOISTURE WILL SLOWLY DECREASE FROM NORTHWEST TO SOUTHEAST DURING THE
DAY WITH THE PRECIPITATION DECREASING SATURDAY MORNING IN THE NORTH
AND BY MID AFTERNOON IN THE CENTRAL SECTIONS. WHILE THE MIXED BAG
PRECIPITATION WILL NOT COMPLETELY END...THE  OVERALL CHANCES OF
WINTRY WEATHER WILL BE ON THE WANE. OVER THE SOUTH...FREEZING RAIN
AND SLEET WILL CONTINUE AS THE COLDEST AIR OF THE SEASON SINKS TO
THE SOUTH.

THE SNOW ADVISORY WILL CONTINUE ACROSS THE NORTH UNTIL NOON WHERE A
TOTAL OF ONE TO THREE INCHES OF SNOW IS EXPECTED. THE WINTER WEATHER
ADVISORIES FOR THE REMAINDER OF THE AREA WILL CONTINUE THROUGH 6 PM.

THE COLD AIR SHOULD START TO MODIFY SUNDAY INTO MONDAY. AS THIS
OCCURS...THE CHANCE OF FREEZING RAIN AND SLEET WILL SPREAD BACK
ACROSS CENTRAL ARKANSAS INTO PARTS OF NORTH CENTRAL ARKANSAS. AREAS
IN SOUTHERN ARKANSAS MAY WARM ABOVE FREEZING AND GO TO A CHANCE OF
LIGHT RAIN. NORTHERN ARKANSAS WILL CONTINUE TO HAVE A CHANCE OF
MOSTLY SNOW.

BY LATE MONDAY...MOST AREAS SHOULD BE NEAR OR A LITTLE ABOVE
FREEZING AND WHAT PRECIPITATION IS LEFT WILL BE LIGHT RAIN.

MUCH OF CENTRAL AND SOUTHERN ARKANSAS COULD HAVE A SIGNIFICANT ICING
OVER THE WEEKEND. IT APPEARS THIS WEATHER SYSTEM WILL NOT BE AS
SEVERE AS THE ICE STORM OF DECEMBER 2000 BUT WILL BE ENOUGH TO CAUSE
SERIOUS DISRUPTION OF TRAVEL AND RESULT IN MANY POWER OUTAGES.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION IS NOT ANTICIPATED.
