SHORT TERM
(THIS EVENING THROUGH TUESDAY)
ISSUED AT 301 PM EDT MON JUN 22 2026
LOW CLOUDS HAVE CLEARED, REPLACED BY THE DEVELOPMENT OF A CU FIELD.
WITH THIS CLEARING, EXPEDITIOUS WARMING HAS OCCURRED. COMBINED WITH
THE ABUNDANT AVAILABLE MOISTURE (THE 12Z SOUNDING SHOWS PRECIPITABLE
WATER OF 1.87 INCHES, ABOVE THE 90TH PERCENTILE), THIS HAS PRODUCED
ISOLATED TO SCATTERED POPUP SHOWERS AND THUNDERSTORMS, PARTICULARLY
OVER NORTH GEORGIA AND THE ATLANTA METRO, WHICH WILL LIKELY CONTINUE
THROUGH MUCH OF THE AFTERNOON, AND POSSIBLY INTO THE EVENING.
LOCALLY HEAVY RAINFALL IS LIKELY, AND GUSTY WINDS. A LINE OF
THUNDERSTORMS IS FORECAST TO PUSH OVER NORTH GEORGIA FROM THE
NORTHWEST AROUND 23-00Z/7-8 PM EDT. IT IS EXPECTED TO DECAY AS IT
APPROACHES AND MOVES OVER THE ATLANTA METRO, THEN LIKELY DISSIPATING
OVER CENTRAL GEORGIA, BECOMING MORE ISOLATED TO SCATTERED SHOWERS
AFTER 12-2 AM EDT. TIMING DOES REMAIN LOW CONFIDENCE WITH THE
ARRIVAL OF THE LINE OF CONVECTION. EARLIEST REASONABLE ARRIVAL TIME
WOULD BE AROUND 6-7 PM EDT AT THE NORTHWEST CORNER OF GA AND 8-10 PM
EDT FOR THE ATLANTA METRO, BUT COULD BE AS LATE AS 9-10 PM EDT TO NW
GA AND 11 PM-1 AM EDT FOR ATLANTA. CURRENT TRENDS ON RADAR AND FROM
MODEL GUIDANCE DO SEEM TO POINT TOWARDS A SCENARIO MORE ON THE EARLY
SIDE, THOUGH. THERE REMAINS SOME UNCERTAINTY, AS WELL, WITH RESPECT
TO THE SPEED OF THE WEAKENING AND DISSIPATION OF THE LINE OVER
CENTRAL GEORGIA, WHICH WILL INFLUENCE HOW MUCH THUNDERSTORM ACTIVITY
THAT AREA SEES. MOST LIKELY, THERE WILL BE A FEW ISOLATED
THUNDERSTORMS FOR CENTRAL GEORGIA, WITH THE HIGHEST RISK ON THE
WESTERN SIDE OF THE STATE, WITH LINGERING RAIN SHOWERS BEHIND.
THERE REMAINS A SLIGHT RISK (2/5) FOR SEVERE THUNDERSTORMS OVER
NORTH GEORGIA INTO THE ATLANTA METRO, MOSTLY AROUND I-20 AND NORTH.
THE GREATEST THREATS ARE DAMAGING WINDS AND FREQUENT LIGHTNING.
CLOUDY SKIES ARE FORECAST TO BUILD IN BEHIND THE SHOWERS AND
THUNDERSTORMS, LASTING AT LEAST INTO MIDDAY TOMORROW ACROSS NORTHERN
AND CENTRAL GEORGIA. THEN, SUNNY SKIES ARE LIKELY BY AROUND MID-
AFTERNOON. MOISTURE DECREASES ACROSS GEORGIA, RESULTING IN
SIGNIFICANTLY LOWER RISK FOR PRECIPITATION TOMORROW. THAT BEING
SAID, SOME LINGERING MOISTURE COULD RESULT IN A FEW SHOWERS, MOSTLY
OVER CENTRAL GEORGIA, DURING THE LATE AFTERNOON.
LONG TERM
(WEDNESDAY MORNING THROUGH NEXT SUNDAY)
ISSUED AT 301 PM EDT MON JUN 22 2026
DRY WEATHER IS FAVORED AT THE ONSET OF THE LONG TERM ON WEDNESDAY IN
THE WAKE OF TUESDAY'S COLD FRONT AMID WEST-NORTHWEST FLOW ALOFT. AT
LEAST ISOLATED TO SCATTERED "SUMMER-LIKE" CONVECTION LOOKS TO RETURN
THURSDAY INTO FRIDAY AS DEEPER MOISTURE RETURNS WITH SOME SUBTLE
MIDLEVEL SHORTWAVES IN THE WEST-NORTHWEST FLOW PROVIDING SOME
ENHANCEMENT.
BY THE WEEKEND, A STOUT SUBTROPICAL RIDGE LOOKS TO ESTABLISH OVER
THE EASTERN PART OF THE COUNTRY, LIKELY PERSISTING INTO NEXT WEEK.
THIS WILL SERVE TO BOTH REDUCE POPS OVERALL AS WELL AS LEAD TO AN
UPWARD TREND IN TEMPERATURES, WITH HIGHS RETURNING INTO THE 90S FOR
MOST. WITH HUMID CONDITIONS REMAINING IN PLACE, TRIPLE-DIGIT HEAT
INDEX VALUES LOOK LIKELY TO RETURN DURING THIS TIME FRAME AS WELL.
