AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LITTLE ROCK AR
250 PM CDT MON SEP 3 2012

.SHORT TERM...TONIGHT THROUGH THURSDAY NIGHT
CLEAR CONDITIONS CURRENTLY PREVAIL ACROSS THE FORECAST AREA. HEAT
INDEX VALUES RANGE FROM 105 10 110 ACROSS THE SOUTHERN 2/3 OF THE
FORECAST AREA. SIMILAR CONDITIONS ARE EXPECTED FOR TUESDAY AFTERNOON.

SEVERAL ROUNDS OF CONVECTIVE COMPLEXES ARE EXPECTED TO FORM AND
MOVE EAST ACROSS THE CENTRAL PLAINS DURING THIS PERIOD...WHICH
COULD AFFECT EXTREME NORTHERN SECTIONS OF THE CWA A SLIGHTLY MORE
PRONOUNCED CHANCE FOR CONVECTION APPEARS LATE IN THE PERIOD...AS A
COLD FRONT APPROACHES FROM THE NORTH. A MUCH MORE SUBSTANTIAL
FRONT WILL CLOSELY FOLLOW...

&&

.LONG TERM...SUNDAY THROUGH MONDAY
...FALL-LIKE WEATHER LOOKS TO BE IN STORE FOR ARKANSAS THIS
COMING WEEKEND.

BY FRI MORNING...UPPER LEVEL FLOW ACROSS THE CONUS WILL HAVE
TRANSITIONED TO A MORE ZONAL PATTERN WITH A MUCH LESS PRONOUNCED
UPPER RIDGE OVER THE SOUTHWEST CONUS. MOVING INTO THE WEEKEND A
STRONG UPPER TROUGH WILL CARVE OUT A HOME ACROSS THE EASTERN HALF OF
THE UNITED STATES THANKS TO A STRONG UPPER WAVE MOVING SOUTH OUT OF
THE NRN ROCKIES AND ACROSS THE PLAINS. THIS WILL LEAVE ARKANSAS
BENEATH NORTHERLY UPPER LEVEL FLOW SUNDAY...AND MONDAY TO A LESSER
EXTENT.

AT THE SURFACE...A STALLED COLD FRONT WILL LINGER IN THE NRN HALF OF
THE STATE FRIDAY...THEN PUSH THROUGH EARLY SATURDAY. WILL HAVE AT
LEAST A CHANCE OF SHOWER/TSTMS BOTH FRI AND SAT...THOUGH THE BEST
CHANCES WILL BY FAR BE LATE FRI NIGHT AND SAT AS STRONG UPPER ENERGY
PRODUCES WIDESPREAD SHOWERS AND THUNDERSTORMS.

AS PREVIOUS SHIFT MENTIONED...MODELS ARE HINTING AT GOOD RAINFALL
AMOUNTS WITH THE STALLED FRONT THU NIGHT AND FRI...THEN ANOTHER GOOD
CHUNK OF RAINFALL LATE FRI NIGHT AND SAT AS THE FRONT PUSHES
THROUGH. CURRENTLY MODELS ARE NOT PREDICTING ENOUGH PRECIPITATION TO
PRODUCED WIDESPREAD FLOODING...BUT WILL NEED TO MONITOR THIS AS THE
WEEK GOES ON AS THE FRONT WILL BE IN THE REGION FOR OVER 24HRS.

FINALLY...FALL-LIKE WEATHER IS IN STORE FOR THE WEEKEND.
AFOREMENTIONED COLD FRONT WILL USHER IN AN AIR MASS THAT WILL
PRODUCE HIGHS IN THE UPPER 70S TO LOW 80S ON SUN AND MON. OVERNIGHT
LOWS IN THE 50S CAN BE EXPECTED SAT AND SUN NIGHTS...WITH SOME
LOCATIONS UP NORTH POSSIBLY FALLING INTO THE UPPER 40S. THIS WILL BE
A WELCOME CHANGE INDEED.
