Damaging Winds in Arkansas, April 9, 2004

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LITTLE ROCK AR
230 PM CDT FRI APR  9 2004

.SHORT TERM...
WATER VAPOR IMAGES SHOW THE ROTATION CENTER OVER OKLAHOMA. IT IS
TRIGGERING THE CURRENT CONVECTION OVER THAT STATE AND SOUTHEAST
KANSAS. THE NEXT IMPULSE IS VISIBLE ALREADY OVER SOUTHEAST NEW
MEXICO. INITIALLY...PRECIPITATION WILL AFFECT MAINLY THE NORTHWEST
SECTIONS OF ARKANSAS...THEN FOCUS WILL SHIFT FARTHER SOUTH WITH NEXT
IMPULSE RIDING IN THE SOUTHWESTERLY FLOW ALOFT. A SURFACE...DOUBLE
BARRELED LOW WILL BE CROSSING THE STATE...THIS WILL SHIFT THE AREA
OF HEAVIER PRECIPITATION TO THE SOUTH AS WELL. EXCESSIVE RAINFALL
DISCUSSION AGREES WITH THIS THINKING...BUT LEAVING OPEN THE
POSSIBILITY OF HEAVY RAIN MORE TO THE NORTH. TEMPERATURES WILL BE
DROPPING TO SOMEWHAT BELOW NORMAL FOR NEXT COUPLE OF DAYS UNDER THE
COOLER FLOW FROM THE NORTH. NORMAL TEMPERATURES WILL RETURN BY MID
WEEK.
&&

.LONG TERM...
STRONG UPPER TROF WILL BE PASSING OVER THE AREA MONDAY NIGHT INTO
TUESDAY AND COLD SURFACE HIGH WILL BE IN THE AREA. THIS SHOULD MAKE
MONDAY NIGHT THE COLDEST NIGHT. WILL BE CLOSE TO FREEZING IN THE
NORTH AND ARKANSAS RIVER VALLEY WHILE OTHER AREAS WILL LIKELY BE IN
THE MID 30S. UPPER RIDGING BUILDS IN LATER IN THE WEEK AND THIS
SHOULD RESULT IN A WARMING TREND. A WEAK FRONT MOVES ACROSS TUESDAY
NIGHT AND WEDNESDAY WITH MODERATE MOISTURE BUT IT LOOKS INSUFFICIENT
AT THIS TIME TO MENTION A CHANCE OF RAIN. THIS MAY TEMPER THE
WARMING A LITTLE WEDNESDAY BUT THINGS SHOULD WARM CONSIDERABLY LATER
IN THE WEEK. PATTERN FOR NEXT FRIDAY LOOKS FAVORABLE FOR MAXES IN
THE 80S IN CENTRAL AND SOUTHERN SECTIONS WITH SOUTHWEST WINDS AROUND
THE SURFACE HIGH AND DEVELOPING LOW PRESSURE TO THE WEST. UPPER TROF
APPROACHES FRIDAY NIGHT WITH MOISTURE INCREASE AND THIS WILL LIKELY
HOLD TEMPS IN 60S IN CENTRAL AND SOUTH.
