TONIGHT...AND WILL BE HEAVY AT TIMES. TWO TO THREE INCHES OF RAIN

MUCH RAIN COULD CAUSE SOME HIGH WATER PROBLEMS. A FLASH FLOOD WATCH
HAS BEEN POSTED FOR MOST OF THE REGION.
ISOLATED TO SCATTERED THUNDERSTORMS WILL BE EMBEDDED IN THE RAIN
AREA...MAINLY IN THE WESTERN HALF OF THE STATE. A FEW STORMS COULD
PRODUCE HAIL.
IT WILL BE WINDY...WITH SOUTHEAST WINDS AT 15 TO 25 MPH AND GUSTS
OVER 30 MPH. A LAKE WIND ADVISORY IS IN EFFECT.
.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY
THE STORM SYSTEM WILL TRACK THROUGH NORTHWEST SECTIONS OF THE STATE
THURSDAY MORNING...AND WILL EXIT TO THE NORTH DURING THE EVENING
HOURS. THE SYSTEM WILL DRAG A COLD FRONT INTO THE STATE...WITH MUCH
COLDER AIR TO FOLLOW.
RAIN AND SCATTERED THUNDERSTORMS WILL CONTINUE EARLY THURSDAY AHEAD
OF THE FRONT. AS THE FRONT SWEEPS ACROSS THE REGION...A SQUALL LINE
MAY DEVELOP. STRONG TO DAMAGING WINDS COULD OCCUR WITH THIS LINE...
ESPECIALLY OVER THE SOUTHERN HALF OF ARKANSAS. AN ISOLATED TORNADO
COULD NOT BE RULED OUT...BUT TORNADOES WILL BE MORE LIKELY ALONG THE
GULF COAST.
AS COLDER AIR ARRIVES...RAIN WILL LIKELY CHANGE TO LIGHT SNOW ACROSS
THE OUACHITA AND OZARK MOUNTAINS THURSDAY AFTERNOON AND EVENING.
THERE MAY BE ENOUGH MOISTURE FOR ONE TO TWO INCH ACCUMULATIONS
NORTHWEST OF MOUNT IDA...RUSSELLVILLE AND MOUNTAIN HOME. FLURRIES
COULD OCCUR AS FAR EAST AS ARKADELPHIA...LITTLE ROCK AND BATESVILLE.
IT WILL BECOME VERY WINDY ON THURSDAY...WITH WINDS SHIFTING TO THE
WEST AND SOUTHWEST AT 20 TO 30 MPH. GUSTS COULD EXCEED 40 MPH. GIVEN
A NEARLY SATURATED GROUND DUE TO HEAVY RAIN...TREES AND POWER LINES
COULD BE DOWNED IN SOME AREAS.
IT WILL REMAIN WINDY ON CHRISTMAS DAY...AND IT WILL BE MUCH COLDER.
CLEARING WILL OCCUR FROM THE SOUTHWEST. WHILE THERE MAY BE
SUNSHINE IN PORTIONS OF CENTRAL AND SOUTHERN ARKANSAS...A FEW
FLURRIES ARE POSSIBLE IN THE NORTH AS MOISTURE WRAPS AROUND THE
DEPARTING SYSTEM TO THE NORTH.
HIGH PRESSURE WILL SLOWLY BUILD OVER THE REGION FROM THE WEST THIS
WEEKEND. WINDS WILL BECOME LESS OF AN ISSUE...AND DRY CONDITIONS ARE
EXPECTED.
EARLY NEXT WEEK...DATA SHOWS A STORM SYSTEM DEVELOPING IN THE
WESTERN GULF OF MEXICO. IT APPEARS THE SYSTEM WILL HEAD TOWARD THE
SOUTHEAST UNITED STATES...AND WILL SPREAD MOISTURE INTO ARKANSAS BY
TUESDAY. WHILE PRECIPITATION IS IN THE FORECAST...IT IS MUCH TOO
EARLY TO SPECULATE WHAT TYPES OF PRECIPITATION WILL OCCUR...OR HOW
MUCH. DETAILS WILL BECOME MORE CLEAR IN THE COMING DAYS.
.SPOTTER INFORMATION STATEMENT...
SPOTTER ACTIVATION MAY BE NEEDED TONIGHT AND THURSDAY MORNING WITH
THE POSSIBILITY OF SEVERE WEATHER ACROSS SOUTHERN ARKANSAS.
