HPC Medium Range Discussion...Interesting

[MWatkins]

They seem to favor the 06Z GFS...in terms of pattern...over the 12Z run and there's more:

E COAST INTERESTS SHUD KEEP AN EYE ON T.D. IRENE IN THE ATL. WHILE THE PREFERRED 06Z GFS DISSIPATES THE SYS BY THE MEDR PD...THE ECMWF...NOGAPS...AND UKMET CARRY THE SYS ALONG THE SWRN SIDE OF THE SUBTROP RIDGE IN THE MEDR...WITH THE 12Z NOGAPS ALLOWING THE SYS TO APPROACH THE MID ATL COAST BY THE END OF ITS RUN ON DAY 6/MON. NOON COORD LED TO A SLOW NWLY TRACK AROUND THE SWRN EDGE OF THE RIDGE...BUT AS UNCERTAINTY IS GROWING IN THE AMPLITUDE AND TIMING OF THE H5 PATTERN OVER WRN NA BY MID PD...IT ALSO GROWS ON THE E COAST. SEE THE LATEST BULLETINS ON IRENE FOR THE OFFICIAL THINKING ON ITS FORECAST TRACK.

I have a hard time understanding all these fancy lingo terms. Can you explain to me what all that means?

Irene needs to be watched closely by those on the east coast...

THERE IS REASONABLE SUPPORT FROM THE D+8 MEAN FOR A MORE
PERSISTENT H5 RIDGE OVER THE E COAST THAN THE PREVIOUSLY PREFERRED
00Z GFS. THE 00Z NCEP ENS MEAN HAD SUPPORTED MORE RIDGING OVER
THE E COAST...AND NOW THE 06Z GFS AND DGEX ARE EVEN MORE
PRONOUNCED WITH THEIR RIDGING ON DAYS 6/MON AND 7/TUES THAN THE
00Z GFS.

Looks like a strenghtening ridge.
