SHORT TERM
(THIS AFTERNOON THROUGH WEDNESDAY)
ISSUED AT 157 PM EDT TUE AUG 11 2026
CURRENT RADAR LOOP SHOWS SCATTERED SHOWERS AND THUNDERSTORMS
DEVELOPING ACROSS THE AREA THIS AFTERNOON. STORMS ARE MAINLY
ACROSS NW GA AND CENTRAL GA AS THERE IS A WEAK WEDGE OF HIGH
PRESSURE BUILDING DOWN THE EASTERN SEABOARD INTO NE GA. LIKE THE
PAST FEW DAYS WE ARE MAINLY EXPECTING THESE STORMS TO STAY BELOW
SEVERE THRESHOLDS BUT CAN NOT RULE OUT AN ISOLATED SEVERE STORM
OR TWO POPPING UP. PWATS ARE CURRENTLY IN THE 2"-2.2" RANGE WITH
MU CAPE AROUND 1500 TO 2500 J/KG AND LIS IN THE -5 TO -7 DEG
RANGE. NOT MUCH SHEER AVAILABLE SO LOOKS LIKE THE GREATEST
CONVECTIVE THREATS ARE PERIODS OF HEAVY RAIN, FREQUENT LIGHTNING
STRIKES, SMALL HAIL, AND STRONG GUSTY WINDS.
WEDNESDAY WILL BE MUCH OF THE SAME AS THE WEDGE BUILDS IN A BIT
FURTHER WITH NW FLOW KEEPING THINGS GOING. TEMPERATURE WED WILL
BE VERY SIMILAR TO TODAY WITH HIGHS IN THE UPPER 80S TO THE MIDDLE
90S.
LONG TERM
(THURSDAY MORNING THROUGH NEXT MONDAY)
ISSUED AT 157 PM EDT TUE AUG 11 2026
AS THE LONG TERM SETS UP, A STRENGTHENING RIDGE WILL BE BUILDING IN
FOR THE WEEKEND. CHANCES FOR AFTERNOON STORMS WILL START TO DECLINE,
WHILE THE RISK FOR EXCESSIVE HEAT RAMPS UP. BY FRIDAY, MOST OF THE
CWA CAN EXPECT APPARENT TEMPERATURES IN THE TRIPLE DIGITS WITH THE
EASTERN PART OF THE FORECAST AREA REACHING HEAT ADVISORY CRITERIA.
WE'LL NEED TO KEEP AN EYE ON TEMPS OVER THE NEXT COUPLE OF DAYS, BUT
IF YOU HAVE PLANS FOR THIS COMING WEEKEND, KEEP THE HEAT IN MIND.
THAT'S WHAT WE DO KNOW. NOW FOR WHAT WE DON'T...
OVER THE NEXT COUPLE OF DAYS WE'LL BE TRANSITIONING INTO NW FLOW.
THIS KIND OF PATTERN IS NOTORIOUS FOR LETTING MCS' MAKE A BIG RUN
ACROSS HALF THE COUNTRY AND END UP ON OUR DOORSTEP. LONG TERM MODELS
STRUGGLE TO PICK THESE OUT FROM THE NOISE, AND AS A RESULT WE'LL
JUST NEED TO WAIT AND SEE HOW THE RIDGE SETS UP OVER THE NEXT FEW
DAYS. THESE RIDGE RIDERS ALSO HAVE A HABIT OF INTERRUPTING
FORECASTED HIGH TEMPERATURES WITH THE INTRODUCTION OF RAIN, MAKING
THE LONG TERM FORECAST A BIT ON THE TRICKY SIDE.
