UPDATE...  
NO SIGNIFICANT CHANGES MADE TO THE FORECAST.  
 
DISCUSSION...  
MADE A FEW ADJUSTMENTS TO THE HOURLY GRIDS, BUT OTHERWISE THE  
FORECAST REMAINS UNCHANGED. WITH THE VERY MOIST GROUND AFTER  
RECENT RAINFALL, WILL KEEP THE MENTION OF PATCHY FOG IN THE  
FORECAST, BUT IT MAY BE LATE TO DEVELOP UNTIL WE GET MORE  
WIDESPREAD SOUTH WINDS TO START PULLING THE HIGHER HUMIDITY AIR  
BACK NORTH.  
 
PREV DISCUSSION... /ISSUED 352 PM CST SAT FEB 24 2018/  
 
DISCUSSION...  
THE STORM SYSTEM RESPONSIBLE FOR THE SHOWERS AND THUNDERSTORMS  
EARLIER TODAY (WHICH ONCE AGAIN MISSED THE VERY DRY NORTHWEST  
PARTS OF OKLAHOMA) IS NOW PUSHING DRIER AIR INTO THE REGION. AN  
AREA OF WEAK HIGH PRESSURE WILL SETTLE OVER OKLAHOMA OVERNIGHT,  
AND THIS WILL RESULT IN GENERALLY CLEAR SKIES WITH LIGHT WINDS.  
THE RESULTING WIDE OPEN RADIATIONAL COOLING WILL PROBABLY RESULT  
IN GROUND FOG OVER MUCH OF THE EASTERN 2/3 OF OKLAHOMA AND  
ADJACENT PARTS OF NORTH TEXAS. IN ADDITION, WEAK MOISTURE  
ADVECTION MAY SPREAD THE POSSIBILITY OF FOG INTO PARTS OF WESTERN  
OKLAHOMA.  
 
AFTER A COUPLE OF UNEVENTFUL DAYS SUNDAY AND MONDAY, MOISTURE  
RETURNS TO NORTH TEXAS AND OKLAHOMA ON TUESDAY. WARM/MOIST  
ADVECTION SHOWERS AND POSSIBLE THUNDERSTORMS WILL LEAD THE WAY  
EARLY TUESDAY, FOLLOWED BY A COUPLE OF DAYS OF (PERHAPS) MORE  
ROBUST CONVECTION THROUGH WEDNESDAY EVENING.  
 
ANOTHER RELATIVELY QUIET PERIOD WILL FOLLOW AS THAT STORM SYSTEM  
DEPARTS TO THE EAST.
