checked the latest shear ensembles;
i think this will be a rain event for the islands and
perhaps a minimal tropical depression if it survives the shear
intensifying to a 40 mph ts prior to florida landfall.
But if shear is strong enough, it will remain a 30 mph
depression as it approaches florida and will do little more
than breezy rains across the state this weekend.
I'll go with a blend- 97L's max intensity based on the shear forecasts
is 35 mph I expect within the next 5 days. Mostly a rain event with some
breezy to occasionally windy conditions.

You have a way with words. Thanks for the reply.
Regarding instincts, I don't think it's unscientific to use instincts - backed by experience, instincts are some of the most powerful tools around, otherwise forecasts would just be computer model outputs.
I do think your forecasts a little "over the top" bullish sometimes. But my original post asking for your methodology wasn't a critque at you, just to clarify.

Re: INVEST 97L: Global & BAM Models
97L won't pose any threat to the GOM will it? I'm reading all of these posts mentioning that it could affect FL. There's no chance of it coming across FL and entering the GOM is there? I certainly hope not.

Re: INVEST 97L: Global & BAM Models
If the shear lets up any, some development may occur.
But regardless of development, this will bring windy thunderstorms
to puerto rico, possibly the dominican republic, other caribbean islands,
and South Florida by Sunday. The caribbean islands and then south florida
can expect some heavy rains and breezes from this.

Re: INVEST 97L: E. Caribbean: Global & BAM Models
With a ridge building: Puerto Rico and the Dominican
Republic, Bahamas, South Florida
lie in the path based on model runs Consistency and synoptics.
Regardless of development there will be squalls of windy rain
on this path. Watch the shear profiles. Right now shear
is forecasted to inhibit 97L, but it needs to be watched.
Until more is known about shear I cannot speculate on intensity.

I do not look at the XTRP in making my predictions.
I clearly stated that we look to Synoptics, not
an arbitrary extrapolated track.

Melbourne NWS discusses the large ridge and the
heavy rain expected with 97L as it approaches Southeast
Florida:

heavy rain expected with 97L as it approaches Southeast
Florida:
weather.gov
National Weather Service
THU-FRI...EVOLUTION OF WEAK MID LEVEL TROUGH AND SURFACE LOW WILL
HAVE A BIG IMPACT ON THE RAIN CHANCES. THE LATEST GFS LIFTS/SHEARS
MID LEVEL TROUGH OUT TO THE NORTHEAST ON THU AND KEEPS DEEP
MOISTURE CONFINED TO THE EAST SIDE OF THE PENINSULA. DRYING IS
FORECAST ON FRI BEHIND THE WEAK LOW AND FRONTAL BOUNDARY ATTACHED
TO IT. HAVE STAYED CLOSE TO THE PREVIOUS FORECAST FOR THU SINCE IT
IS CLOSE TO THE MAV GUIDANCE...AGAIN CONFINING LIKELY POPS TO THE
SOUTHERN PART AND 40-50 PERCENT ELSEWHERE. THE 12Z MEX GUIDANCE
HAS POPS AROUND 20 PERCENT FRI BUT HAVE NOT GONE THAT LOW YET AND
WILL STAY WITH 30 PERCENT EXCEPT 40 IN THE SOUTH.
WEEKEND-EARLY NEXT WEEK...THE GLOBAL MODELS HAVE BEEN TRENDING TO
AN ONSHORE FLOW DEVELOPING SAT AS LARGE HIGH PRESSURE SYSTEM
PUSHES ACROSS THE EAST COAST. THE LATEST GFS IS SHOWING DEEP
MOISTURE ASSOCIATED WITH TAIL END OF OLD FRONTAL BOUNDARY WORKING
BACK ACROSS THE AREA FROM THE ATLANTIC BY SUNDAY AND BECOMING
BREEZY. THIS SHOWERY PATTERN IS PROGGED TO HOLD INTO EARLY NEXT
WEEK AND GIVEN A RATHER GOOD MODEL CONSENSUS...WE SHOULD END THE
MONTH ON THE WET SIDE.

Re: INVEST 97L: E. Caribbean: Global & BAM Models
The models have 97L as a moderate TS near the end of the run. The NHC is pretty much writing this off saying upper levels are not favorable for a few days, how can any confidence be given to the SHIP, and if there is very low confidence what is the point of that prediction?

With 98 already in the area, wouldn't that greatly affect the ability fo this to do anything?
