EASTERN OKLAHOMA/NORTHWEST ARKANSAS FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
1030 AM CST THU MAR 14 1996

NOT SURE WHAT TO THINK.  LOW LEVEL MOISTURE QUITE SHALLOW AS
EXHIBITED BY NEIGHBORHOOD SOUNDINGS AND 8H CHART.  YESTERDAY
THOUGHT THERE WOULD BE LOW CLOUDS ACROSS THE AREA AT THIS TIME...
BUT INSTEAD HAVE MID AND HIGH CLOUDS.  THERE ARE LOW CLOUDS IN
EASTERN TEXAS...BUT NOT SURE THEY WILL MAKE IT THIS FAR BEFORE
DISSIPATING SINCE THERE IS A LOT OF DRY AIR ABOVE THEM TO MIX THEM
OUT.  HIGH CLOUD GLOBULE SEEMS TO BE MAKING STEADY PROGRESS
NORTHEAST AND HAVE A FEELING MOST AREAS WILL BREAKOUT SOMETIME THIS
AFTERNOON.  TRENDS OF HIGH CLOUDS SEEM CLOSER TO THE NGM SOLUTION
WHICH WOULD HAVE THE BEST LIFT OVER EASTERN KANSAS AND MISSOURI BY
THIS EVENING.  WITH SHALLOWNESS OF MOISTURE AND STRONG CAP
INDICATED ON OUN AND FWD SOUNDINGS LIKE THE LOW POPS IN THE
FORECAST.  DO NOT REALLY LIKE THE MENTION OF SEVERE IN NORTHEAST
OKLAHOMA...BUT DO NOT WANT TO HAVE TO YO-YO AND SPC DAY 1 STILL
HAS US IN A SLIGHT RISK AREA ON UPDATE.  WEAK COLD FRONT TO MOVE
ACROSS THE AREA TONIGHT SO EVEN THOUGH BEST DYNAMICS BEING GONE
LATE TONIGHT MENTION OF THUNDER ALL NIGHT SEEMS O.K.  AIR MASS
BEHIND THE FRONT LIKELY TO BE MORE STABLE AND SHOULD END
THUNDERSTORM THREAT FOR A FEW DAYS.
