NWS Atlanta, GA wrote its last area forecast discussion before the first event at Jul 1, 4:12 AM EST, 6 hours 58 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PEACHTREE CITY GA 512 AM EDT SUN JUL 1 2007 .SHORT TERM /TODAY THROUGH TUESDAY/... EASTERN U.S. TROUGH CONTINUES TO STRENGTHEN AS POLAR VORTEX DEEPENS...RESULTING IN STRENGTHENED NW FLOW ALOFT ACROSS THE REGION. PERSISTENT UPPER LOW...WITH TROPICAL FEED...REMAINS IN THE TX/OK AREA...AND WILL DRIFT S BACK INTO TX BY MON AS IT REMAINS TRAPPED BETWEEN LARGE UPPER RIDGE WESTERN U.S. AND STRENGTHENING TROUGH EASTERN U.S. NAM MODEL INITIALIZES BEST...BUT BECOMES AN OUTLIER BY MON-TUE AS IT TRIES TO ABSORB THE SOUTHERN PLAINS LOW INTO THE EASTERN U.S. TROUGH. NONE OF THE OTHER GLOBAL MODELS SHOW THIS SOLUTION...AND BASED ON HISTORY...THIS WILL NOT OCCUR. THUS...BEYOND THIRD PERIOD...NAM WAS DISREGARDED. WEAK SFC BOUNDARY EVIDENT IN WIND FIELD AND DEWPOINT DISCONTINUITY ACROSS NC/NE GA. BOUNDARY SERVES AS THE BEST SFC FOCUS FOR CONVECTION...INTERACTING WITH SHORT WAVES IN NW FLOW ALOFT. SUCH WAS THE CASE SAT AFTERNOON...EVEN CONTINUING WELL PAST MIDNIGHT IN SE PARTS OF THE CWA. NOT UNUSUAL FOR NW FLOW ALOFT. AN EVEN STRONGER DISTURBANCE...NOW EVIDENT AS AN AREA OF TSRA ACROSS AR...WILL APPROACH THE AREA LATE TODAY. JUST LIKE YESTERDAY...ACTIVITY MAY GET A LATE START THANKS TO A WEAK SHORT WAVE RIDGE OVER THE AREA TODAY AD SOME STABILIZATION BEHIND DEPARTING CONVECTION...BUT EXPECT SCT-NMRS SHRA/TSRA ACTIVITY BY LATE AFTERNOON/EVENING. AS THE SFC BOUNDARY SINKS JUST A LITTLE FURTHER SOUTH...EXPECT THE BEST FOCUS FOR CONVECTION THIS AFTERNOON/EVENING TO BE SOUTHWEST OF A RMG-ATL-MCN LINE...WITH THE NE CORNER SEEING THE LEAST CONVECTION. STORMS ARE ONCE AGAIN EXPECTED TO BE EFFICIENT LIGHTNING PRODUCERS WITH HOT AFTERNOON TEMPS AND HIGH PW VALUES...LEADING TO HIGH VILS...OFTEN AN INDICATOR OF INTENSE CG LIGHTNING. HAVE AGAIN HIGHLIGHTED FREQUENT LIGHTNING IN THE ZONES. LOCALLY HEAVY RAIN WILL ALSO BE A CONCERN WITH PW VALUES IN EXCESS OF 1.75 INCHES. HOWEVER...HAVE CHOSEN NOT TO MAKE AN ISSUE OF THIS IN LIGHT OF THE OVERALL DRY CONDITIONS. CONVECTION WILL LIKELY AGAIN CONTINUE PAST MIDNIGHT ACROSS CENTRAL/WEST CENTRAL GA. FOR MON-TUE...THE BOUNDARY SHOULD CONTINUE TO PUSH GRADUALLY SOUTH...AND THE BEST FOCUS FOR CONVECTION...AGAIN MOSTLY DURING THE LATE AFTERNOON/EVENING...WILL BE A LITTLE FURTHER SOUTH EACH DAY. AS THE PAST SEVERAL DAYS...HAVE GONE WELL ABOVE MOS POPS...INTO THE LIKELY RANGE IN SOME AREAS. FOR TEMPS...AS NOTED YESTERDAY...THE MEX/MAV HAVE JUST BEEN WAY TOO COOL. PERSISTENCE THE BEST FORECASTER LATELY FOR MAX TEMPS...SO HAVE AGAIN RAISED 00Z MAV MOS SEVERAL DEGREES IN MOST AREAS. MOST AREAS WERE 5 DEGREES OR BETTER ABOVE MAV MOS YESTERDAY. WAS NOT ABLE TO ACCEPT DRASTIC COOLING OF HIGHS INTO THE MID 80S FOR MON-TUE...AND THUS KEPT MOST AREAS CLOSER TO 90. HIGHS IN THE 80S HAVE NOT VERIFIED AT ALL RECENTLY. .LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/... NORTHWEST FLOW ALOFT WILL PREVAIL THROUGH THE EXTENDED PERIOD. THE SFC BOUNDARY WILL EVENTUALLY BE PUSHED FURTHER SOUTH...BUT SHOULD STALL SOMEWHERE IN S GA AND REMAIN THERE MUCH OF THE WEEK. NOTE THAT THE GFS CONTINUES TO SLOW THE SOUTHWARD PROGRESSION OF THIS FEATURE WITH EACH RUN...AS TO BE EXPECTED AT THIS TIME OF THE YEAR. WEAK DISTURBANCES ALOFT WILL CONTINUE TO AFFECT THE AREA FROM TIME-TO-TIME...AND THUS CANNOT REMOVE POPS ANYWHERE IN THE EXTENDED...INCLUDING THE 4TH. IN FACT...GFS NOW SHOWING A FAIRLY HEALTHY SHORT WAVE THAT COULD RESULT IN INCREASED SHRA/TSRA ACTIVITY IN THE NC/NE PART OF THE STATE THE EVENING OF THE 4TH. A STRONGER DISTURBANCE AND ANOTHER WEAK FRONT WILL MOVE INTO THE AREA LATE FRI-SAT. AGAIN...CONFIDENCE IN TIMING OF THIS FEATURE IS LOW. WILL NEED TO KEEP AT LEAST LOW POPS THROUGH MOST PERIODS OF THE EXTENDED...BUT FOCUS ON THE SOUTH NEAR THE INITIAL LINGERING BOUNDARY AND IN ALL AREAS FRI-SAT AS THE NEXT RIPPLE IN THE FLOW AFFECTS THE AREA. NEWEST MEX GUIDANCE IS QUITE A BIT WARMER THAN EARLIER RUNS...ESPECIALLY THU. 850MB TEMPS THU IN THE +20C TO +21C RANGE AND WITH DOWN SLOPING NW WINDS AND GOOD AMOUNTS OF SUNSHINE...HAVE ADVERTISED SOME OF THE HOTTEST TEMPS OF THE YEAR FOR THU AFTERNOON. NOTE...MOS GRIDDED DATA SHOWING 98-100+ IN THE SW/WC PART OF THE CWA FOR THU AFTERNOON. SLIGHT COOLER TEMPS FOR FRI-SAT. && .AVIATION... PERSISTENCE CONTINUES TO BE THE KEY IN THIS FORECAST. ATL/MCN AREAS HAD RAIN DURING THE PAST 24 HOURS...HOWEVER VERY LITTLE FOG HAS DEVELOPED EARLY THIS MORNING. THIS IS MAINLY DUE TO EXTENSIVE HIGH LEVEL CLOUDS OVER THE STATE. THE CIRRUS WILL THIN OUT THROUGH THE MORNING HOURS AND EXPECT ANOTHER CU FIELD TO DEVELOP BY NOON WITH ISOLATED TO SCATTERED CONVECTION ACROSS THE ENTIRE AREA. BIGGEST FORECAST PROBLEM WILL BE THE WINDS. NAM BRINGS THE WINDS AROUND TO THE NORTHEAST ACROSS MOST OF THE AREA BY DAYBREAK WHILE THE GFS HOLDS OFF ON THAT UNTIL THIS EVENING. WITH A WEAK PRESSURE GRADIENT OVER THE REGION AND THE SURFACE BOUNDARY LAYING ACROSS THE AREA...FEEL VARIABLE WINDS TO NEAR CALM MORE LIKELY THAN ANYTHING ELSE THIS MORNING. FOR THIS AFTERNOON WILL START COMPROMISING THE NAM/GFS SOLUTION AND START BRINGING THE WINDS TO THE NORTHEAST IN ATL AND AHN AREAS BUT KEEPING THE WINDS LESS THAN 10 KTS EXCEPT IN THE THUNDERSTORMS. IN CSG AND MCN FEEL THE BOUNDARY WILL KEEP THEIR WINDS VARIABLE THROUGH MOST OF THE DAY WITH ALL LOCATIONS GOING NEAR CALM TONIGHT. WILL KEEP CIGS VFR EXCEPT IN TSRA. && .PRELIMINARY POINT TEMPS/POPS...
