250 PM CDT FRI JUL 23 2004

.SHORT TERM...TONIGHT THROUGH MONDAY NIGHT
ISOLATED TO SCATTERED THUNDERSTORMS BROKE OUT THIS AFTERNOON...AS A
BOUNDARY ACROSS CENTRAL ARKANSAS INITIATED CONVECTION. COLD FRONT IS
IN NORTHERN ARKANSAS...ALTHOUGH IS IT MAINLY A WIND SHIFT LINE AS
THE DRIER AIR IS STILL IN NORTHERN MISSOURI.

BROAD UPPER LEVEL TROUGH OVER THE GREAT LAKES REGION WILL MOVE OFF
TO THE EAST. THIS WILL ALLOW THE FRONT TO MOVE SLOWLY SOUTH THROUGH
THE STATE. GFS LOOKS TO MOVE THE FRONT THROUGH TOO FAST...WHILE THE
ETA LOOKS TOO SLOW. WENT WITH A COMPROMISE...LEANING MORE TOWARD THE
GFS EXCEPT IN QPF AMOUNTS. DO EXPECT HEAVY RAINFALL WITH THIS
SYSTEM...AS PRECIPITABLE WATER VALUES ARE OVER 2 INCHES.
HOWEVER...PINPOINTING THE EXACT REGION OF HEAVY RAINFALL WILL DEPEND
ON SMALL FEATURES. AT THIS TIME...THINK THE GREATEST CHANCE OF
SEEING HEAVY RAIN WILL BE IN THE NORTHERN AND WESTERN SECTIONS OF
THE AREA...CLOSER TO THE UPPER LEVEL DYNAMICS. DUE TO THE WEAK WIND
FIELDS...STORMS WILL ALSO BE SLOW MOVING.

A COUPLE OF SHORTWAVES WILL MOVE EAST OUT OF THE ROCKIES INTO THE
BASE OF THE TROUGH. THESE WILL BRING MORE THUNDERSTORM ACTIVITY TO
THE STATE. AT THIS POINT...HIGHEST RAIN CHANCES WILL BE SATURDAY
INTO SATURDAY EVENING. HOWEVER...DUE TO THE MODEL DISCREPANCIES
...RAINFALL POTENTIAL COULD REMAIN INTO LATE SATURDAY NIGHT. DID NOT
FEEL COMFORTABLE EXTENDING LIKELY POPS THAT FAR OUT DUE TO THE
DIFFERENCES.

RAINFALL WILL GRADUALLY COME TO AN END SUNDAY IN THE NORTH...AND
SUNDAY NIGHT IN THE SOUTH. CANADIAN HIGH PRESSURE MOVES INTO THE
REGION ON SUNDAY...BRINGING DRY WEATHER BACK TO THE STATE.
&&

.LONG TERM...TUESDAY THROUGH FRIDAY
AREA STAYS DRY TUESDAY WITH SURFACE HIGH PRESSURE TO THE NORTHEAST
BRINGING A PROLONGED PERIOD OF NORTHEAST TO EAST SURFACE WINDS TO
THE AREA. SHORT WAVE IN DANGEROUS NORTHWEST FLOW MOVES MOSTLY
THROUGH KANSAS AND OKLAHOMA AT FIRST AND APPEARS EFFECTS OF IT WILL
STAY TO THE WEST UNTIL THURSDAY. ON THURSDAY INTO FRIDAY...WEAK
CLOSED LOW SWINGS THROUGH SOUTHERN ARKANSAS WITH AN ACCOMPANYING
AREA OF MOISTURE. PUT IN SMALL POPS FOR THURSDAY FOR SOUTHERN HALF
OF THE AREA...CONTINUING THURSDAY NIGHT AND FRIDAY MORNING...THEN
WENT WITH 30 POPS IN THE SOUTH FOR FRIDAY AFTERNOON WITH 20 POPS
ELSEWHERE. MADE LITTLE CHANGE TO TEMP GRIDS. PATTERN FAVORS MAXES A
LITTLE BELOW NORMAL WITH MINS NEAR OR A LITTLE BELOW NORMAL.
