Area forecast discussion, Aug 6, 3:36 PM CDT, 2 hours 37 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LITTLE ROCK AR
336 PM CDT TUE AUG 6 2002

THE COLD FRONT IN MISSOURI HAS NOW MADE ITS WAY INTO NORTH ARKANSAS.
SHOWERS AND THUNDERSTORMS ARE NOTED ALONG THE FRONT ON KLZK RADAR.
SCATTERED SHOWERS AND THUNDERSTORMS WILL SPREAD INTO THE STATE
TONIGHT. THIS COLD FRONT WILL SLOWLY MOVE SOUTH TONIGHT AND EXIT THE
STATE ON WEDNESDAY. WILL KEEP A SLIGHT CHANCE OF THUNDERSTORMS IN
THE NORTH THROUGH NOON TOMORROW AND A CHANCE ELSEWHERE THROUGHOUT
THE DAY.

AVN SEEMS TO BE DOING WELL WITH THE GIVEN SCENARIO. MUCH DRIER AND
SOMEWHAT COOLER AIR WILL MOVE IN BEHIND THE FRONT ON WEDNESDAY. DEW
POINTS WILL DROP INTO THE 60S ACROSS THE AREA. DRY WEATHER IS
EXPECTED UNTIL A COLD FRONT IN THE PLAINS MOVES INTO THE AREA ON
SATURDAY. WILL PUT A CHANCE OF SHOWERS AND THUNDERSTORMS IN FOR THE
WEEKEND. ABUNDANT MOISTURE WILL MOVE IN AHEAD OF THIS FRONT...FROM
REMNANTS OF BERTHA. WITH THIS AMOUNT OF MOISTURE APPRECIABLE
RAINFALL AMOUNTS MAY BE EXPECTED. FUTURE FORECASTS WILL NEED TO
WATCH THIS.

STAYED CLOSE TO THE MAV TEMPERATURE GUIDANCE. THE MAV SEEMS TO HAVE
A GOOD HANDLE ON THE SITUATION.

.LZK...NONE.
