Weak, unstable northwest flow was also noted across Georgia, while a warm, moist, unstable air mass continued at the surface. Scattered strong to severe thunderstorms developed during the afternoon across east central Georgia producing damaging downburst winds and nickel to quarter-sized hail.

DRIER AIR SHOULD WORK ITS WAY INTO NORTH GEORGIA TODAY BEHIND THE WEAK SHORT WAVE AND SURFACE TROUGH THAT HELPED TRIGGER A FEW MORE STORMS YESTERDAY THAN EXPECTED. IT ALSO APPEARS THAT THE ODDS THAT ANY LARGE SCALE OUTFLOW BOUNDARIES ASSOCIATED WITH THE OVERNIGHT CONVECTION OVER THE CENTRAL PLAINS AND MID MISSISSIPPI VALLEY WILL MOVE INTO THE STATE ARE MUCH SMALLER THAN YESTERDAY AS WELL. WITH ALL THAT...I STILL AM RELUCTANT TO REMOVE ALL CHANCES FOR AFTERNOON AND EARLY EVENING CONVECTION ACROSS THE NORTH WITH STRONG SURFACE HEATING AND ADEQUATE RESIDUAL MOISTURE EXPECTED. WILL KEEP SLIGHT CHANCE IN THE NORTH FOR THE AFTERNOON AND EVENING WITH A CHANCE ACROSS THE SOUTH WHERE BETTER MOISTURE AND WEAK LOW CONVERGENCE REMAIN. THE REMAINDER OF THE SHORT TERM FORECAST PERIOD SHOWS LITTLE CHANGE FROM THE LARGE SCALE PATTERN WE HAVE BEEN STUCK IN FOR THE PAST SEVERAL DAYS. LARGE UPPER RIDGE REMAINS IN PLACE FROM THE GULF OF MEXICO NORTHWARD INTO THE SOUTHERN PLAINS AND EAST ACROSS THE SOUTHEASTERN U.S. NORTH AND CENTRAL GEORGIA REMAIN TOWARD THE EDGES OF THIS RIDGE...WITH ENOUGH SUBSIDENCE FOR VERY WARM TEMPERATURES BUT NOT QUITE ENOUGH TO SQUASH THE DIURNAL CONVECTION CYCLE. ALTHOUGH IT GETS CLOSE ACROSS THE SOUTHERN THIRD OF THE FORECAST AREA...HEAT INDICES AND MORNING LOWS SHOULD REMAIN BELOW ADVISORY LEVELS. LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/... NO SIGNIFICANT CHANGES TO THE LARGE SCALE PATTERN IS EXPECTED THROUGH THE EXTENDED FORECAST PERIOD AS WELL. UPPER RIDGE FLATTENS...REBOUNDS AND SHIFTS EAST AND WEST A LITTLE THROUGHOUT THE PERIOD...BUT REMAINS ESSENTIALLY IN PLACE ACROSS THE SOUTHERN U.S. VERY WARM TEMPERATURES AND ISOLATED TO SCATTERED...MAINLY DIURNAL...CONVECTION IS EXPECTED THROUGH THE UPCOMING WEEK AND INTO NEXT WEEKEND.
