Area forecast discussion, Aug 1, 3:46 PM CDT, 37 minutes before
NORTHWEST ARKANSAS/EASTERN OKLAHOMA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
345 PM CDT THU AUG 1 1996

SIGNIFICANT SHORTWAVE SEEN IN WATOR VAPOR LOOP DROPPING SOUTHEAST
INTO THE FORECAST AREA.  DARKENING BEHIND IT INDICATES STRONG
SUBSIDENCE AND DO NOT EXPECT RAIN AGAIN TONIGHT AFTER THE SHORTWAVE
PASSES THROUGH NORTHWEST ARKANSAS.  SHOULD SOMETHING GET GOING OVER
THE WESTERN PLAINS WOULD THINK IT WOULD TAKE UNTIL TOMORROW MORNING
TO GET HERE.   WILL INCLUDE LOW POPS ALL DAY TOMORROW INTO TOMORROW
NIGHT CONSIDERING THIS AND THAT THE ETA SHOWS ANOTHER SHORTWAVE
DROPPING INTO THE FORECAST AREA.  LOOKS LIKE AFTER TOMORROW
NORTHWEST FLOW PATTERN WILL END AS UPPER RIDGE BUILDS IN FROM THE
WEST.  EXPECT WARMING TREND CONSIDERING THIS AND ALSO AN END
TO THE PATTERN OF DYING MCS'S MOVING INTO THE AREA.  THUS...IT
SHOULD BE DRY SATURDAY OTHER THAN ISOLATED HEAT OF THE DAY STORMS
AND THINK CHANCES ARE LOW ENOUGH NOW TO LEAVE THEM OUT.
