.PREV DISCUSSION... /ISSUED 947 PM CDT MON APR 21 2014/

DISCUSSION...
THE LAST LONE SHOWER IS IN THE PROCESS OF DISSIPATING JUST SOUTH
OF TULSA AT THIS TIME. THUS WILL REMOVE ALL POPS FROM THE
FORECAST. DRIER LOW LEVEL AIR WILL BE ADVECTING INTO THE AREA
OVERNIGHT WHICH SHOULD HELP PREVENT SIGNIFICANT FOG FORMATION.
SOME LIGHT FOG WILL BE POSSIBLE BUT IT SHOULD NOT BE WIDESPREAD OR
DENSE ENOUGH TO MENTION IN THE ZONES. HAVE LOWERED SKY COVER SOME
OVERNIGHT AND MADE JUST A FEW MINOR DOWNWARD ADJUSTMENTS TO
OVERNIGHT LOWS.

UPDATE ON THE WAY.
