EASTERN OKLAHOMA/NORTHWEST ARKANSAS FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
400 PM CDT MON MAY 17 1999

PROBLEM(S) OF THE DAY:
HOW MUCH RAIN WILL FALL?
WILL THERE BE SEVERE CONVECTION?

DO NOT HAVE MUCH TIME SO THIS WILL BE SHORT.

ANSWERS TO THE PROBLEMS OF THE DAY ARE A DEFINITIVE YES...AT LEAST
FOR THE NEXT FEW HOURS ANYWAY.  STRONG TO SEVERE CONVECTION AND FLASH
FLOODING ARE ONGOING AND WILL CONTINUE INTO THE EARLY EVENING HOURS.
ACTIVITY WILL COME TO AN END AS A COLD FRONT PUSHING SOUTHEAST ACROSS
NORTHEAST OKLAHOMA AT THIS TIME PUSHES THROUGH NORTHWEST ARKANSAS AND
AND SOUTHEAST OKLAHMA.  MUCH DRIER AND MORE STABLE AIR TO MOVE INTO
THE AREA.

SHOULD SEE A DECLINE IN THE WIND AND CLOUDS OVERNIGHT AS WELL SO MOS
LOWS APPEAR REASONABLE.  BEST COOL NIGHT LIKELY TOMORROW NIGHT WITH
CLEAR SKIES AND LIGHT WINDS ACROSS THE AREA.  HIGH PRESSURE TO BE IN
CONTROL THE NEXT DAY OR SO THEN WINDS RETURN TO THE SOUTH.  AVN
BRINGS A SHORTWAVE TO OUT OF THE SOUTHWEST WEDNESDAY NIGHT BUT
BELIEVE ACTIVITY WILL STAY TO OUR WEST AND NORTH.  PREDOMINANT
PATTERN WILL BE UPPER LOW OVER THE ROCKIES AND A RIDGE OVER THE
CENTRAL U.S. THROUGH THE EXTENDED.  THUS...WILL KEEP THE FORECAST DRY
AND WARM.
