DISCUSSION...  
MUCH COOLER AND DRIER AIR WILL REMAIN ENTRENCHED ACROSS THE AREA  
AS A 1030 PLUS SFC HIGH. GOOD RADIATIONAL COOLING WILL SEND  
OVERNIGHT LOWS INTO THE 40S AREAWIDE, AND WITH OVERNIGHT LOWS NEAR  
40 LAST NIGHT OVER SE OK, EXPECT MORE FAVORABLE CONDITIONS TO SEND  
TEMPS INTO THE UPPER 30S FOR MUCH OF AREA NORTH OF I-30, WHERE  
PATCHY LIGHT FROST MAY ALSO OCCUR. TUESDAY NIGHT MAY GET AS COOL  
ACROSS MUCH OF AREA ALTHOUGH BEST SFC BASED INVERSION WILL LIKELY  
OCCUR FURTHER SOUTH, WITH OVERNIGHT LOWS STILL IN THE 40S, BUT  
CLOSER TO UNIFORMITY ACROSS AREA. THUS, COOLER NAM GUIDANCE MORE  
IN LINE WITH FCST. SFC HIGH ONLY SLIGHTLY DRIFTS EAST OF MS RIVER  
BY WED, WITH SUNNY SKIES STILL HOLDING THRU MID WEEK AND MOSTLY  
SUNNY THRU THU AND AFTN HIGHS JUST REACHING AROUND 80 DEGREES  
AGAIN. MODELS IN LESS AGREEMENT GOING INTO THE WKND REGARDING THE  
TIMING AND POSITION OF WHERE APPROACHING SFC LOW WILL BECOME  
CUTOFF, BUT LIKELY OR GREATER POPS AND LOCALLY HEAVY RAIN REMAIN  
A POSSIBILITY DEPENDING ON THIS PARAMETER. BUT WILL MAINTAIN ONLY  
HIGH CHANCE POPS UNTIL THE PICTURE BECOMES MORE APPARENT./07/
