Potential Tropical Cyclone Eight Discussion Number 1
NWS National Hurricane Center Miami FL AL082024
500 PM EDT Sun Sep 15 2024
Reports from an Air Force Hurricane Hunter aircraft indicate that
the non-tropical low pressure system off the South Carolina coast
has a broad low-level circulation center, but could be in the
process of reforming closer to the mid-level circulation currently
seen on radar from Wilmington, NC. However, the system may not have
yet completely shed its frontal characteristics. Since there is deep
convection over and around the center, it is becoming more
likely the cyclone could become either a tropical or subtropical
cyclone within the next day or so. Therefore the disturbance is
being designated as Potential Tropical Cyclone Eight at this time
with an initial intensity of 40 kt.
There has been significant uncertainty in the center positions since
last night, and the best guess at initial motion is northwestward or
320/6 kt. Over the next couple of days, the disturbance is expected
to be steered by the flow on the southern or southwestern side of a
mid-level high pressure system over the northeastern United States.
This motion should bring the center inland over the southeastern
U.S. coast in 24 hours or so. The NHC forecast track is close to
the simple and corrected dynamical consensus model solutions.
the system will be traversing warm waters for the next 24 hours or
so and it may be situated within an area of relatively low shear
near the axis of an upper-level trough. Therefore some
strengthening is possible before landfall, and the official forecast
is similar to the latest decay-SHIPS model guidance.

It could be deceptive since it’s based on the IR satellite loop, but it sure looks like this is not drifting NW like a lot of the model guidance had suggested about now. It almost looks like it may be moving NNE, but that could be the IR fooling me and this may be due to shearing. But if so, that should favor a NC rather than the SC that the GFS/Euro have.

Per NHC there has been a very slow drift to the NW, but they expect it to speed up to the NW:

The Potential Tropical Cyclone (PTC) has become a bit better
organized tonight, with deep convection on the northeast side of the
circulation. Additionally, the last aircraft pass just north of the
estimated center of the system indicated that the temperature
gradient from east-to-west had weakened. However, it is still
unclear whether a well-defined center exists looking at the latest
satellite and radar animations, with the center that the plane found
earlier looking somewhat elongated. For now, the system will remain
a Potential Tropical Cyclone, and the winds are set to 40 kt. An Air
Force Reserve reconnaissance aircraft is scheduled to be in the area
overnight for a better look at the system's structure.
It appears the system has only drifted northwest since this
afternoon. The PTC should move a bit faster to the northwest on
Monday and Tuesday due to flow from a ridge over the northeastern
United States. There is general agreement on this track in the
models, though they differ on the speed. The new forecast is
trended a bit slower than the last one, but not as slow as the
ECMWF model.
The system has a high chance of being a tropical cyclone early
tomorrow, and some strengthening is possible before landfall as it
moves over warm waters with a conducive upper-level trough
interaction. The official forecast is similar to the latest
decay-SHIPS model guidance and the prior forecast.

I always pay close attention to the outflow to as it will give you a good indication of where the center will heads towards. The outflow is clearly moving NW.

The Icon has folded and brings this farther west. Most models showing 1 inch plus of rain here now.

2 to 5 is way under doing it. Places along the coast already have 10 and that big nasty looking area of convection with MLC is headed right for mby

Radar shows a hybrid more than tropical system....also sure looks like at the very least the mlc is going nnw into the Cape Fear region.

Spinups showing up in that band to the east of the center. Wherever that rotates onshore should see some tornado warnings
Sporadic lightening and thunder, with I'd estimate near 30 mph gusts here. Core of the storm is approaching pretty quick hoping for no Tor.

Strengthening gradient should bring some decent gusts into the 30s inland today. I guess the drought around here is pretty much gone now.
