Below normal rainfall continued during the month of August which expanded severe (D2) drought conditions to additional portions of Northwest Mississippi. The biggest impact from the drought was on agriculture as many crops suffered due to the lack of rainfall.

/ISSUED 800 PM CDT SAT JUL 31 2010/
DISCUSSION...
UPDATED FOR SHOWERS IN NORTH AND NOTHING IN SOUTH. TEMPERATURES
LOOK GOOD FOR TONIGHT.
SHOWERS AND THUNDERSTORMS RUNNING INTO SLIGHTLY DRIER AND MORE
CAPPED AIR IN PARTS OF THE MID-SOUTH. EXPECT THE CURRENT SHOWERS
TO DIMINISH AS THEY MOVE SOUTHEAST. THERE MAY BE SOME MORE
DEVELOPMENT IN THIS AREA SO HAVE LEFT POPS HIGHER IN THE NORTH FOR
TONIGHT. HAVE LOWERED POPS IN SOUTHERN 2/3RDS OF THE COUNTY
WARNING AREA AND THUS HAVE REMOVED WEATHER FROM MUCH OF ZONES. TLSJR

/ISSUED 330 PM CDT SAT JUL 31 2010/
DANGEROUS HEAT EXPECTED THIS WEEK ACROSS THE MIDSOUTH.
SCATTERED SHOWERS AND THUNDERSTORMS HAVE DEVELOPED THIS AFTERNOON
ACROSS SOUTHERN MISSOURI. THESE SHOWERS AND THUNDERSTORMS ARE
ASSOCIATED WITH A FRONTAL BOUNDARY. THE FRONT WILL MOVE INTO THE
MIDSOUTH OVERNIGHT. SHOWERS AND THUNDERSTORMS MAY DEVELOP OR MOVE
INTO THE CWA THIS EVENING ALONG THE FRONT. EXPECT MUCH OF THE
ACTIVITY TO DIE OUT BY MIDNIGHT. HOWEVER WILL KEEP 20 POPS THROUGH
12Z. WARM AND HUMID NIGHT EXPECTED ACROSS THE CWA WITH LOWS IN THE
MID 70S TO AROUND 80 DEGREES.
SUNDAY...UPPER RIDGE WILL BUILD OVER THE MIDSOUTH BRINGING IN EVEN
WARMER TEMPERATURES. HIGHS WILL BE IN THE UPPER 90S ACROSS THE
ENTIRE CWA. FRONT THAT IS EXPECTED TO MOVE INTO CWA TONIGHT WILL
STALL OUT FROM CENTRAL ARKANSAS TO CENTRAL MISSISSIPPI. MODELS ARE
INDICATING A FEW SHOWERS AND THUNDERSTORMS COULD DEVELOP ALONG THE
FRONT WHICH WOULD POSSIBLY AFFECT EAST CENTRAL ARKANSAS AND
NORTHWEST MISSISSIPPI DURING THE DAY. WILL THROW IN A 20 POP. THE
BIGGEST CONCERN WITH THE FRONT WILL BE THE POOLING OF HIGHER
DEWPOINTS. CURRENTLY DEWPOINTS ARE RUNNING IN THE MID 70S ACROSS
PORTIONS OF NORTHWEST AND MIDDLE TENNESSEE IN THE VICINITY OF THE
FRONT. THIS COULD OCCUR ACROSS SOUTHWESTERN PORTIONS OF THE CWA ON
SUNDAY. THE COMBINATION OF HIGHER DEWPOINTS AND HIGHS IN THE UPPER
90S COULD PRODUCE HEAT INDICES AROUND 110 DEGREES. AN EXCESSIVE
HEAT WATCH WILL BE ISSUED FOR SOUTHWESTERN PORTIONS OF THE CWA FOR
THIS REASON.
MONDAY THROUGH WEDNESDAY...HEAT WILL BE BRUTAL ACROSS THE MIDSOUTH
AS THE UPPER RIDGE STRENGTHENS OVER THE AREA. THE BIG QUESTION WILL
BE WHAT THE DEWPOINTS WILL DO DURING THE AFTERNOON HOURS. HIGHS WILL
TOP THE CENTURY MARK POSSIBLY REACHING AS HIGH AS 101-102 DEGREES.
DEWPOINTS COULD MIX DOWN KEEPING HEAT INDICES BELOW 110 DEGREES.
HOWEVER IF DEWPOINTS STAY EVEN AS HIGH AS 72-73 DEGREES...HEAT
INDICES COULD STILL REACH 110 DEGREES. HEAT WARNINGS MAY BE
NEEDED DURING THIS PERIOD. WILL CONTINUE EXCESSIVE HEAT WATCH FOR
SOUTHWESTERN PORTIONS OF CWA THROUGH MONDAY WHILE EXPANDING THE
HEAT ADVISORY FOR THE REST OF THE CWA THROUGH MONDAY. NO RAIN IS
EXPECTED DURING THIS TIME.
THURSDAY THROUGH EARLY NEXT WEEKEND...LOOKS LIKE MODELS WANT TO HOLD
ONTO THE RIDGE ALTHOUGH IT MAY WEAKEN SLIGHTLY THURSDAY BEFORE
RE-INTENSIFYING EARLY NEXT WEEKEND. HIGHS WILL REMAIN IN THE UPPER
90S. DIURNAL ISOLATED SHOWERS OR THUNDERSTORMS COULD ALSO OCCUR.
HIGH HEAT INDICES WILL LIKELY CONTINUE THROUGH THE PERIOD.
