AREA FORECAST DISCUSSION...UPDATED FOR AVIATION
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
133 AM EDT MON JUL 28 2014
.UPDATE...
/ISSUED AT 950 PM EDT SUN JUL 27 2014/
REALLY HAVE NOT MADE TOO MANY SIGNIFICANT CHANGES TO THE SHORT TERM
FORECAST GRIDS THIS EVENING. A FEW ADJUSTMENTS FOR TIMING OF
CONVECTION DROPPING SOUTH INTO NORTHERN TN RIGHT NOW AS THE ACTIVITY
THAT HAS BEEN MOVING ACROSS THE APPALACHIANS FROM EASTERN TN INTO
WESTERN NC SHOULD REMAIN EAST OF THE FORECAST AREA. ALL INDICATION
ARE THAT THE CONVECTION WILL BE WEAKENING AS IT APPROACHES NORTH GA
SOMETIME IN THE 02-04AM TIME FRAME...BUT ENOUGH INSTABILITY REMAINS
FOR AT LEAST SCATTERED THUNDER. WILL NEED TO MONITOR TRENDS CLOSELY
THROUGH THE EVENING FOR ANY SEVERE THREAT HOLDING ON INTO THE STATE.
THE REMAINDER OF THE FORECAST LOOKS GOOD RIGHT NOW SO NO OTHER
CHANGES MADE.

.PREV DISCUSSION... /ISSUED 740 PM EDT SUN JUL 27 2014/
SHORT TERM /TONIGHT THROUGH MONDAY NIGHT/...
HIGH PRESSURE WILL CONTINUE ACROSS THE NORTH CENTRAL GULF OF MEXICO
THIS EVENING. A COLD FRONT CURRENTLY STRETCHES FROM THE CENTRAL
GREAT LAKES BACK THROUGH THE CENTRAL PLAINS STATES. THE FRONT WILL
DROP SOUTH OVERNIGHT AND BEGIN APPROACHING THE CWFA BY SUNRISE
MONDAY.
MODELS HAVE BEEN CONSISTENT WITH PRODUCING CONVECTION ALONG THE
TN/GA BORDER OVERNIGHT. THIS SEEMS REASONABLE...AS ANY LEFT OVER
CONVECTION FROM LATE THIS AFTERNOON/EVENING IS PROGGED TO DROP SOUTH
ACROSS TN. LATEST RUNS OF THE HRRR HAVE THE SHOWERS AND
THUNDERSTORMS MOVING INTO NORTHERN GA BETWEEN 06Z AND 08Z. THE
STORMS SHOULD WEAKEN AS THEY GET AWAY FROM THE BEST MID LEVEL
FORCING AND DYNAMICS.
ADDITIONAL STORMS ARE EXPECTED TO DEVELOP BY THE EARLY AFTERNOON
ALONG THE FRONT AND/OR ANY LEFTOVER OUTFLOW BOUNDARY FROM THE EARLY
MORNING CONVECTION. IF THE EARLY MORNING CONVECTION PRODUCES ENOUGH
BLOW OFF TO LIMIT HEATING ACROSS THE SOUTHERN HALF OF THE
CWFA...THUNDERSTORM SEVERITY AND COVERAGE WILL BE LIMITED.
HOWEVER...IF GOOD HEATING IS REALIZED...THE POTENTIAL FOR SEVERE
THUNDERSTORMS WILL BE HIGHER. ANY SEVERE THUNDERSTORM THAT DEVELOPS
WILL HAVE THE POTENTIAL TO PRODUCING DAMAGING WIND GUSTS AND LARGE
HAIL. LOCALLY HEAVY RAINFALL WILL ALSO BE POSSIBLE.
MODELS HAVE ALSO BEEN CONSISTENT WITH MOVING THE DRY AIR IN BEHIND
THE FRONT RATHER QUICKLY. SO...RAPID CLEARING WILL BE POSSIBLE
ACROSS THE NORTHERN CWFA BY MID AFTERNOON. ONLY SOME LINGERING
ACTIVITY IS EXPECTED ACROSS THE FAR SOUTH DURING THE EARLY
EVENING...WITH THE OVERNIGHT HOURS EXPECTED DRY.
NLISTEMAA
LONG TERM /TUESDAY THROUGH SUNDAY/...
MAINLY ONLY TWEAKS TO THE LONG TERM BASED ON THE LATEST GUIDANCE.
WITH THE MUCH COOLER AIRMASS BEHIND THE NEXT COLD FRONT...SOME LOW
TEMPERATURE RECORDS WITH BE THREATENED WEDNESDAY MORNING AND
POSSIBLY AT CSG THURSDAY MORNING. TUESDAY MORNING LOWS WITH BE
WITHIN 3-5 DEGREES OF THE RECORD LOWS FOR THAT DAY. LEANED HARD ON
WPC HIGH/LOW TEMPERATURES AND POPS FOR WEDNESDAY AND BEYOND.
BDL
PREVIOUS DISCUSSION...
THE FRONTAL BOUNDARY THAT AFFECTS THE STATE MONDAY WILL BE SOUTH OF
THE CWA BY 12Z TUE. THIS FRONTAL PASSAGE USHERS IN A AN UPPER LEVEL
DEEP LONG WAVE TROUGH WHICH REMAINS POSITIONED OVER THE AREA THROUGH
MUCH OF NEXT WEEK...KEEPING LOWER DEW POINTS AND COOLER TEMPERATURES
IN PLACE AT LEAST THROUGH WED/THU. MOISTURE BEGINS TO INCREASE AGAIN
BY THE END OF THE WORK WEEK ACROSS SOUTHERN PORTION OF OUR CWA. WILL
KEEP DIURNALLY DRIVEN SLIGHT TO LOW CHANCE POPS IN ACROSS THE AREA
DAYS 6 AND 7. BEGINNING TUESDAY...SHOULD SEE BELOW AVERAGE
TEMPERATURES WITH HIGHS IN THE UPPER 70S NORTH AND LOW 80S
ELSEWHERE...AND LOWS IN THE 60S. TEMPS WILL REBOUND BY THU/FRI WITH
NEAR NORMAL READINGS BY THEN.
