DISCUSSION... /ISSUED 333 AM CDT SAT JUN 24 2017/  
 
A COLD FRONT HAS MOVED THROUGH THE MIDSOUTH, CURRENTLY LOCATED  
ALONG A LINE FROM GREENWOOD, MS TO COLUMBUS AIR FORCE BASE TO  
JASPER, AL. DEW POINTS ALONG AND SOUTH OF THE FRONT REMAIN IN THE  
MIDDLE 70S. A DRIER AIRMASS IS MOVING IN FROM THE NORTH. AT WALNUT  
RIDGE, AR AND PINE BLUFF, MO, DEW POINTS ARE IN THE LOW 60S. THAT  
DRIER AIR SHOULD GRADUALLY PUSH ACROSS THE MIDSOUTH DURING THE  
DAY TODAY. ANY RAIN SHOWERS SHOULD BE CONFINED TO NORTHEAST MS  
TODAY. CLOUDS MAY LINGER FOR MUCH OF THE DAY ACROSS NORTH MS AND  
EAST CENTRAL AR, BUT MOST OF WEST TN...THE MISSOURI BOOTHEEL AND  
NORTHEAST AR SHOULD SEE SOME SUNSHINE BY THE AFTERNOON HOURS.  
 
WE WILL SEE ZONAL TO WEAK NORTHWEST FLOW OVER THE MIDSOUTH TODAY  
AND TOMORROW...GRADUALLY TRANSITIONING TO STRONGER NORTHWEST FLOW  
EARLY NEXT WEEK. THE SYNOPTIC PATTERN MONDAY NIGHT IS THE TYPE WE  
IN WHICH OFTEN SEE MCS'S THIS TIME OF YEAR IN THE MIDSOUTH.  
GUIDANCE DOES SHOW SOME INDICATION OF THIS HAPPENING...BUT THESE  
SYSTEMS ARE NOTORIOUSLY DIFFICULT TO FORECAST MORE THAN JUST 12  
HRS OUT. WILL INCLUDE 20% POPS FOR NOW AND KEEP THE HWO HAZARD-  
FREE BUT THIS WILL BE A TIME FRAME THAN NEEDS TO BE CLOSELY  
MONITORED OVER THE WEEKEND.  
 
TEMPERATURES THIS WEEKEND INTO EARLY NEXT WEEK WILL BE BELOW  
NORMAL...IN THE LOW TO MIDDLE 80S FOR HIGHS WITH OVERNIGHT LOWS  
RANGING FROM THE UPPER 50S TO MIDDLE 60S.  
 
NORTHWEST FLOW WILL BECOME ZONAL AGAIN BY MIDWEEK. SURFACE HIGH  
PRESSURE WILL SHIFT TO THE EAST ALONG THE ATLANTIC COAST. FOR NOW  
I DO NOT SEE ANY SIGNS OF ORGANIZED STORMS NEXT WEEK...BUT  
AFTERNOON SUMMERTIME POP-UP THUNDERSTORMS WILL BECOME A BIT MORE  
LIKELY THURSDAY AND FRIDAY AS TEMPERATURES REBOUND INTO THE UPPER  
80S. IT LOOKS LIKE ENHANCED RAIN CHANCES WILL RETURN NEXT WEEKEND  
AS A BROAD TROUGH DEVELOPS OVER THE PLAINS AND SHIFTS EAST.
