ULL Over Jacksonville MAULING Franklin

[dhweather]

This little low is absoloutely slaughtering Franklin. If this continues, we
don't have to worry about Franklin anymore.

Good observation with the upper low. However the shear impacting Franklin is sourced more to the south and is moving in about high pressure that is over the Northwest Caribbean. That upper low might actually help Franklin tomorrow by introducing more divergent winds in the upper levels that would help storm outflow.

That appears to be an upper jet which if it was north of Franklin, would provide about all the evacuation required to spin up a nice little system. It's kind of a quasi boundary between the tropical airmass and the trof digging down and almost itself looks like a trof split. If it hangs around, it would be interesting to see if it is north of 91L tomorrow and if it allows any ventilation of that system.

That seems to be the only thing keeping this storm from going to a hurricane

The Florida ULL has actually sheltered Franklin by cutting off the Yucatan system's shear, and providing a divergent environment aloft over Franklin; it is not surprising to me that new convection has sprouted overnight.

Predictaguesstimate: The ULL and Franklin will begin to fujiwara around each other and eventually merge or stack up. The way this will look on satellite is Franklin going stationary (or east drift slower than model forecasts) while the ULL sinks south and east under Franklin, then Franklin moves southwest ("loop" models previously predicted) as ridge builds north, while ULL swings around and is eventually cannibalized by the tropical system.

Looks like that little ul circulation is being spit to the southeast pretty quickly.
A little too calm in Georgia at the moment for my likes but that doesn't mean the trough will miss.
The ridge between Franklin and the trough is getting chewed real thin so unless the ridge starts sinking in the next few hours there won't be much left of Franklin.
