BAROCLINIC ZONE ALONG THE FRONT...WITH TEMPS IN THE 70S AHEAD AND

MOISTURE WAS RATHER SHALLOW THOUGH...AND A GOOD CAP WAS SPREAD OUT
AHEAD OF THE FRONT. THIS MIGHT INHIBIT WIDESPREAD SEVERE WEATHER
WITH THE FRONT THIS EVENING...THOUGH I WOULDN/T BE SURPRISED IF A
FEW WARNINGS BEING ISSUED. THE LINE OF SHOWERS/STORMS WILL TO RIDE
THE FRONT AS IT GETS INTO SOUTHEAST ARKANSAS BY 12Z. THE MOST LIKELY
AREA FOR ANY SEVERE WEATHER WOULD BE NC AND NE AR...WHERE FORCING
WILL BE A LITTLE STRONGER AND INSTABILITY A LITTLE GREATER.

CANADIAN HIGH MOVES IN OVERNIGHT. WINDS WILL REMAIN GUSTY BEHIND THE
FRONT...WHICH WILL ALLOW COLD AIR TO QUICKLY MOVE INTO PLACE.
LOWERED MINS FOR FRIDAY MORNING A LITTLE FROM GOING FORECAST AS GOOD
MODEL AGREEMENT ON THE COLD AIR INCREASED CONFIDENCE. HIGHS FOR

THE WEST QUICKLY...PUSHING DRY AIR OVER THE STATE FROM 00Z TUESDAY

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

.DAY ONE...THIS AFTERNOON AND TONIGHT

A STORM SYSTEM AND COLD FRONT WILL PUSH ACROSS ARKANSAS LATER TODAY
AND THIS EVENING. AHEAD OF THE FRONT...STRONG AND GUSTY SOUTHWEST
WINDS WILL BE NOTED WITH WIND SPEEDS MOSTLY BETWEEN 15 AND 25 MPH.
GUSTS WILL BE AS HIGH AS 35 MPH.

GIVEN THE WINDY CONDITIONS...A LAKE WIND ADVISORY HAS BEEN POSTED
TODAY FOR MUCH OF ARKANSAS. THE WINDS WILL CAUSE CHOPPY CONDITIONS
ON AREA LAKES...WITH BOATERS ADVISED TO USE CAUTION.

THE COLD WILL FRONT WILL ALSO PRODUCE STRONG TO SEVERE
THUNDERSTORMS THROUGH THIS EVENING. SOME OF THESE STORMS COULD
POSSIBLY BE TORNADIC BUT LARGE HAIL AND STRONG DAMAGING WINDS ARE
THE PRIMARY CONCERN. A TORNADO WATCH IS IN EFFECT UNTIL 9 PM FOR
ROUGHLY THE WESTERN HALF OF ARKANSAS.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY

MUCH COLDER AIR WILL SPREAD ACROSS THE REGION BEHIND THE FRONT TO
BEGIN THE WEEKEND. THE COLD AIR WILL BE SHALLOW...BUT TEMPERATURES
WILL BE 30 TO 40 DEGREES COOLER THAN ON THURSDAY. IN FACT...
TEMPERATURES MAY REMAIN BELOW FREEZING IN MUCH OF NORTHERN AND
CENTRAL ARKANSAS FROM SATURDAY THROUGH SUNDAY AND INTO MONDAY
MORNING.

THE FRONT BRINGING THE COLD AIR WILL STALL ALONG THE GULF COAST. A
SYSTEM ALOFT FROM THE PLAINS WILL INTERACT WITH THE FRONT LATE
FRIDAY NIGHT AND SATURDAY...WITH LOTS OF CLOUDS AND PRECIPITATION
DEVELOPING. JUST ABOVE THE SHALLOW COLD AIR...THERE WILL BE A WARM
LAYER ALOFT. PRECIPITATION WILL FALL THROUGH THE WARM LAYER AS RAIN
BUT WILL FREEZE AS IT REACHES THE GROUND.

FREEZING RAIN AND SLEET ARE IN THE FORECAST ACROSS MUCH OF NORTHERN
AND CENTRAL ARKANSAS FRIDAY NIGHT INTO SATURDAY. TOWARD THE MISSOURI
BORDER...THE COLD AIR MAY BE DEEP ENOUGH FOR SOME LIGHT SNOW...WITH
MAINLY RAIN TOWARD THE LOUISIANA BORDER WHERE TEMPERATURES REMAIN
ABOVE THE FREEZING MARK.

THERE MAY BE A LULL IN THE PRECIPITATION SATURDAY AFTERNOON AS
ARCTIC HIGH PRESSURE NEARS THE AREA FROM THE NORTHWEST. HOWEVER...AS
THE HIGH MOVES SLOWLY EAST SATURDAY NIGHT...WARM AND MOIST AIR WILL
ATTEMPT TO HEAD TOWARD ARKANSAS BEHIND THE HIGH...AND WILL OVERRUN
COLD AIR ACROSS THE STATE. THE RESULT WILL BE MORE CLOUDS AND
ANOTHER ROUND OF WINTRY PRECIPITATION INTO SUNDAY.

THIS SECOND ROUND OF PRECIPITATION WILL BE MOSTLY IN THE FORM OF
FREEZING RAIN AND SLEET ACROSS NORTHERN AND CENTRAL SECTIONS OF THE
STATE...WITH RAIN IN THE SOUTH. ICY PRECIPITATION MAY LINGER INTO
THE FIRST PART OF PRESIDENTS DAY.

GIVEN THE LONG TERM DURATION OF FREEZING RAIN AND SLEET THIS
WEEKEND...A MAJOR ICE STORM MAY BE IN THE WORKS. ROADS WILL LIKELY
BECOME TREACHEROUS...WITH PERHAPS ENOUGH ICE TO DOWN TREES AND POWER
LINES AND CAUSE WIDESPREAD POWER OUTAGES. PEOPLE IN ARKANSAS ARE
ADVISED TO MONITOR LATER FORECASTS...AND SHOULD BE PREPARED FOR
LATER WATCHES AND WARNINGS.

A NEW AREA OF HIGH PRESSURE WILL BUILD INTO THE REGION FROM THE
NORTHWEST ON PRESIDENTS DAY. THE HIGH WILL FORCE THE STALLED FRONT
ALONG THE GULF COAST TO MOVE AWAY...WITH PRECIPITATION FINALLY
ENDING.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION IS NOT ANTICIPATED.
