.DISCUSSION...

THE MIDSOUTH IS EXPERIENCING PLEASANT WEATHER THIS AFTERNOON. SKIES
ARE MOSTLY SUNNY TO PARTLY CLOUDY. DRY CONDITIONS WILL BE COMING TO
AN END BY FRIDAY MORNING. A COLD FRONT WILL APPROACH THE AREA
LATE TONIGHT. A LINE OF SHOWERS AND THUNDERSTORMS ARE EXPECTED TO
DEVELOP ALONG THE FRONT. THE LINE SHOULD BEGIN ENTERING NORTHWESTERN
SECTIONS OF THE CWA AFTER MIDNIGHT. THE LINE IS CURRENTLY DEVELOPING
AND IS EXPECTED TO BE SEVERE ACROSS MUCH OF MISSOURI...NORTHWEST
ARKANSAS...SOUTHEAST KANSAS...AND NORTHWEST OKLAHOMA. BY THE TIME THE LINE
REACHES THE MIDSOUTH IT SHOULD BE IN A DYING PHASE. HOWEVER...THERE
IS A CHANCE THAT SOME OF THE STORMS COULD BE SEVERE WITH LARGE HAIL
AND DAMAGING WINDS BEING THE MAIN THREAT. SPC HAS THE MISSOURI
BOOTHEEL AND NORTHEAST ARKANSAS IN A SLIGHT RISK. IN ADDITION...SOME
EVENING SHOWERS AND THUNDERSTORMS COULD OCCUR AS A SHORTWAVE MOVES
THROUGH THE CWA AHEAD OF THE FRONT. HOWEVER...ANY THUNDERSTORMS THAT
OCCUR WILL STAY BELOW SEVERE LIMITS DURING THE EVENING HOURS.

FRIDAY MORNING...FRONT WILL BE LOCATED NEAR NORTHWESTERN SECTIONS OF
THE CWA. INITIAL LINE SHOWERS AND THUNDERSTORMS WILL BE LOCATED OVER
EASTERN SECTIONS OF CWA. LINE SHOULD EXIT MIDSOUTH BY MIDDAY. AS THE
DAY PROGRESSES...COLD FRONT WILL CONTINUE MOVING EASTWARD INTO THE
REST OF THE CWA. SHOWERS AND THUNDERSTORMS ARE EXPECTED TO REDEVELOP
DURING THE AFTERNOON HOURS. THE ATMOSPHERE WILL BE VERY UNSTABLE OUT
AHEAD OF THE FRONT WITH CAPES NEAR 3000 J/KG. THE AREA WILL ALSO BE
IN A FAVORABLE REGION OF THE UPPER LEVEL JET. SOME OF THE
THUNDERSTORMS THAT DEVELOP HAVE THE POTENTIAL OF BECOMING SEVERE.
THERE IS A MODERATE RISK FOR MAINLY AREAS EAST OF THE MISSISSIPPI
RIVER.  LARGE HAIL...DAMAGING WINDS...AND POSSIBLY A FEW ISOLATED
TORNADOES ARE POSSIBLE. FRONT MAY LINGER INTO FRIDAY EVENING ALONG
WITH THE THREAT FOR SEVERE WEATHER.

BY SATURDAY MORNING...COOLER AIR WILL MOVE INTO THE AREA AS HIGH
PRESSURE BUILDS INTO THE MIDSOUTH. COOL AND DRY WEATHER WILL
CONTINUE INTO EARLY NEXT WEEK. LOW TEMPERATURES MAY REACH FREEZING
SUNDAY MORNING...MAINLY ACROSS PORTIONS OF NORTHWEST TENNESSEE.

SEVERAL COLD FRONTS WILL MOVE THROUGH THE MIDSOUTH THROUGH THE
MIDDLE OF THE WEEK. THIS WILL BRING CHANCES FOR RAIN BACK TO THE
AREA.
