Recommended Posts

Great thread on the main board but, felt like the SE should have it's own. Interesting quote from NHC Disc.

DEBBY IS THE EARLIEST 4TH STORM IN THE HISTORICAL RECORDS...

SURPASSING HURRICANE DENNIS OF 2005...WHICH BECAME A TROPICAL STORM

ON JULY 5TH.

All that tropical juice down in the Eastern Gulf of Mexico but a massive road block (trough) that is settling into the Interior Southeast will prevent of that moisture from getting much farther north than Interstate 10.

With the exception of Lee (last year) there has always been either a massive trough to shove it off the Florida East Coast or a massive expanding ridge to send it towards Texas.

Why can't we get just get a massive Bermuda Ridge with storms coming moving around the western edge?

Been raining along the west coast of Florida all day! I've seen about 10 minutes of sunshine since Tuesday night, when I arrived here. Great way to spend a vacation! Tracking two tropical systems :D Now... I have to drive through it all on the way back to Columbus tomorrow... :( Hell, at the rate we're going, I wouldn't be surprised to see this thing come more north than others are thinking.

ummmm...EURO just jumped from Texas to New Orleans overnight.

GFS has refused to take Debby westward.

Here is part of the 4:00 am CDT discussion from the NHC:

WITH INFRARED IMAGERY THE CENTER...ALTHOUGH PARTIALLY EXPOSED...HAS

BECOME A LITTLE MORE DIFFICULT TO LOCATE AND THE FIXES FROM TAFB

AND SAB ARE ABOUT 50 MILES APART. MY BEST ESTIMATE OF INITIAL

MOTION IS SLOWLY NORTHWARD...OR 360/3. THE TRACK FORECAST FOR THIS

STORM IS EXTREMELY CHALLENGING. THE SYNOPTIC REASONING IN PREVIOUS

ADVISORIES WAS BASED ON A MID-LEVEL RIDGE BUILDING TO THE NORTH OF

THE TROPICAL CYCLONE...WHICH WOULD CAUSE DEBBY TO MOVE TOWARD THE

NORTHWEST GULF OF MEXICO COAST IN SEVERAL DAYS. THAT TRACK

SCENARIO WAS SUPPORTED BY THE ECMWF MODEL...WHICH HAS BEEN THE

BEST-PERFORMING GUIDANCE OVER THE PAST FEW YEARS. HOWEVER...THE

0000 RUN OF THAT MODEL HAS SHIFTED SUBSTANTIALLY TO THE NORTH AND

EAST OF THE PREVIOUS RUNS. THE U.K. MET. OFFICE MODEL HAS ALSO

SHIFTED SIGNIFICANTLY TO THE RIGHT. IN FACT...ONLY THE HWRF MODEL

IS CLOSE TO THE PREVIOUS OFFICIAL FORECASTS...AND EVEN IT IS TO THE

NORTH OF THEM. THEREFORE AN UNUSUALLY LARGE RIGHTWARD ADJUSTMENT

TO THE NHC FORECAST IS REQUIRED...AND ADDITIONAL SHIFTS TO THE

NORTH AND EAST MAY BE NECESSARY IN SUBSEQUENT ADVISORY PACKAGES.

NEEDLESS TO SAY...THIS IS A LOW CONFIDENCE FORECAST.

I'm starting to wonder if maybe Debby has long term plans of hanging out in the Gulf...I 'm not sure there will be enough influence by the developing trough in the east to pull her across Florida. On the other hand, maybe Debby will interfere with the ridge that's expected to develop later this week across the Southeast and just wonder around the Northern Gulf Coast.

Anyone in Apalahicola here?

As a matter of fact I am. I'm spending the next 7 days a few miles west of Apalachicola in Cape San Blas. We are currently trapped on the cape since the road into Port St Joe is closed due to the bay flooding. It's been pouring rain since about midnight with steady 30-40 mph winds. We went down to the beach this morning and the waves are up in the dunes. I would have taken some pictures but I don't want to risk my camera. Walking into the wind was quite the experience. If its going to rain on vacation I would rather it do this. The bad news is the power has been flickering for 2 hours and we have to entertain my 21 month old son.

I have stayed at the State Park there many times. That rd washes over at the Stump Hole if someone sneezes! It also has a tendancy to wash out there. Great place to watch a smaller storm, strength wise for sure. Is the gas staion at Scallop Cove open?

I just got back from Scallop Cove. They had a Panama City news crew filming a backhoe working on the rocks at the stump hole. The waves were crashing up against him so it was pretty cool. The bay was up to the road on the other side but the road was fine. Scallop Cove only had two workers for the day since the roads are closed. The wind has picked up real good in the last few minutes. I'm trying to get some video from inside but I'm sure it won't do it justice. This almost reminds me a strong winter storm in the high country only with rain instead of snow.

You staying at Barrier Dunes condos by any chance....stayed there many years in the 80's and 90's....Very Familiar with the area you are describing...

Going to keep my weenie-ish thoughts outside of the main thread

Honestly dont know what to expect down near Orange Beach. I'm pretty excited as I've never been in a TS, other than remnants passing through Atlanta. Models are such a crapshoot right now. :axe:

Very envious of you! I might have to agh....well.... run down to Destin to take care of the boat. ;)

We just finished our vacation, we are from MD. We left Anna Maria Island this morning and are at my Parents house in Palmetto. Last night on the Island was interesting. Just saw on the local news that county police are telling people to not visit Anna Maria. Going to be heading back home tomorrow.

Hope you got to see some weather & it didn't interfere with your trip

Any sort of tropical storm is quite a event. I have probably been through 10-15. I won't bore you with alot of war stories but expect the unexpected for sure.

THAT TRACK

BEST-PERFORMING GUIDANCE OVER THE PAST FEW YEARS

Someone hasn't been paying attention. As a forecaster, I'm bound to adhere strictly to no biases....that said, I can't help but snicker and wonder what in the world folks are doing still bashing GFS , and claiming somehow the old ECMWF, the former superior model, when clearly the GFS has led the way for 18 consecutive months. I think old ways of thinking die really hard. Paying close attention to the Southeast in general, because I have to , and because it's my favorite forecasting region, those verification charts showing ECMWF on top are nothing but kindling. Ever since just after the Christmas 2010 storm, the GFS has shown every major weather event in our region in GENERAL....I know some areas it hasn't been quite so accurate, but in general, I've noticed it picked up on MCC events, if you know how to look for their beginnings, any damming events, even surface temp forecasting, when the GFS was really, really bad back in the day. Things have really changed hard, but like I said, the old mentality is still very much alive. Thank God I'm unbiased on go with which model makes the most sense and obviously GFS has the hot hand really.

Anyway, full free update at wxsouth.com if you're interested. Click "register" and then "public" or "current weather".

What's more interesting to me is the upcoming heat wave late week. The Carolinas and Virginia are going to bake. GFS shows some very rare air of +27 degrees at 850...we normally get our heat waves at +24 and a ridge of 594dm. There is good westerly low level flow to aid in the downslope warmth in the Piedmont, but as always, something could pop up to shave a couple degrees off potentially some of the hottest air in years. High cirrus clouds, ground moisture etc. I'm rooting against this. I haven't been 100 degrees in a couple Summers now..and don't miss it a bit.

By the way, for the those that know me and my drought situation and mongering, I'm getting tons of rain here...it's never really stopped, other than the dry Winter. Doing just fine, and getting daily storms pretty regularly. I have to say it's very nice to feel "normal" after over decade of truly getting skipped in northwest flow.

Nice outflow just passed through - too bad it isn't pulling any weather along with it. Really hoping for something with the frontal passage tomorrow evening ... we've only had 1.39" this month, and will be gone over next weekend's heat wave, with no one to water the gardens for us. I don't know anyone, family or friends, who will spend 4 hours a day watering by hand what I do during dry conditions. When your retired life is your gardens, yeah, you fret over such petty things.

We are staying in a house on the south facing part of the cape. Today has been awesome but if this thing stalls it will grow old very quickly.

I was in Sarasota up until this morning. Here's what I posted in the main forum:

I just got done driving through much of that rain in Florida on my way back to Columbus, GA from Sarasota, FL. I left before the worst of it hit. Here's a view of Siesta Key Beach, the one I went to a few days ago... The Lifeguard towers are typically 20 ft from the water's edge... https://www.facebook...&type=1

Here's another of else where on Siesta Key: https://www.facebook...&type=1

The weekend meteorologist at ABC 7 in Sarasota went to Ringling Bridge, the one that leads to Longboat Key, and shot this video: https://www.facebook...479213778771809

I know some have said that the GFS didn't win completely, but I'd respectfully disagree. Yes, it did have a few solutions cutting it across Florida, but a good majority had it in the Eastern Gulf, which is where it is now. It never bit on the Texas solution like almost every other model did. It's done incredibly well this season versus the Euro.

As Robert mentioned, the GFS has done really well over the past year plus. It nailed Beryl earlier in May, showed Debby forming over a week out and even had it coming ashore near PCB, which is where it's close to heading! I would know, I sent a tweet about it to a viewer who has a house in Florida and wanted to know. The trough ended up a bit stronger, the center of circulation was more east than most of the other models had it and it kept trudging north-northeast. I even mentioned a few days ago in the main forum to watch how far north Debby goes. It's heading north and COULD get stuck in the Gulf, though I think it may make a rare Big Bend Landfall.

Also, my chief just "happened" to head to PCB and is posting videos off and on: https://www.facebook.com/WRBL3
