Area forecast discussion, Oct 26, 1:18 AM EDT, 2 hours 44 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSONVILLE FL
115 AM EDT SUN OCT 26 1997

WHILE STRIVING TO USE THE UPMOST IN SCIENTIFIC PRINCIPLES IN MY
FORECASTING...MY KNEE HAS CONTINUED TO THROB HORRIBLY FOR THE LAST
18 HOURS (THANK YOU HIGH SCHOOL ATHLETICS). THEREFORE FORGET ETA...
NGM OR AVN AND WILL GO WITH THE TRICK KNEE MDL!

SERIOUSLY...YDA'S ETA MDL SEEMS TO HAVE HAD THE RIGHT IDEA WITH THE
GRTST RH'S IN SRN GA...IT WAS JUST A LTL LATE IN INCRG THE RH AND
WELL UNDERDONE WITH THE PCPN AMOUTS. 88D STP TOTALS OF 4 TO 5 INCHES
ARE OCCURRING IN SERN GA ALONG THE TRAIN-ECHO RGN. HVST TOTALS RUNNING
FROM NR PEARSON THRU BLACKSHEAR TO NR JESUP. LOOKING AT SAT IMGRY
TOPS ARE CRNTLY WARMING AND THE UPR DIFFLUENCE APPRS TO BE SHIFTING TO
THE NE. IN THE SHORT RUN...XPCT THE STDY PCPN TO SETTLE DOWN BTWN
3-5 AM BEFORE RESUMING THIS AFTN.

LOOKING AT THE MDL RUNS...ETA HAS DEFINITELY OUTPERFORMED THE OTHER
MDLS LAST FEW DAYS AND CONTINUES TO DO SO AS OF 26/06 UTC FCST. THE
80 PCNT RH LINE ALMOST PERFECTLY OUTLINES THE CRNT PCPN AREA...WHILE
NGM HAS A 40 PCNT POPS IN AREAS THAT HAVE HAD INCHES OF RA SO FAR!
SO WILL AGAIN GO WITH THE ETA/AVN RUNS AND WILL TRASH NGM.

THIS AFTN BTWN 18-24 UTC ETA HAS A SIGNIFICANT H8 JET COMING OUT OF
APALACHEE BAY AND INTO SRN GA. JUST WITH THE LLVL MSTR FEED OUT OF
THE GLFMEX HVY RA SHUD OCCUR IN THE GA PTN OF THE CWA THIS AFTN/EVE.
ATL MIGHT WISH TO CONSIDER A FLOOD WATCH FOR SERN GA. AFTER THAT THERE
IS THE CONT'D SEVERE THREAT FOR THE SAME RGN AND ALSO INTO NERN FL
INTO THE EVENING HOURS.

BOTTOM LINE IS IN MY OPINION NGM/FWC GUID ISN'T WORTH A... . SO
THEREFORE WILL LEAN HEAVILY TWD THE FAN GUIDANCE.
