What is a Tutt Low?

[Karla Dorman]

This one's got me stumped. I'd appreciate any and all answers.

From this afternoon's AFD, DFW:

... The most interesting feature in the long term is the Tutt low which develops in the Gulf in the easterlies of the 500 MB ridge over the SE Conus. Both the GFS and the ECMWF have this feature ... Both models keep the system in Gulf until Friday when they begin to move it west towards the Texas Gulf. ...

What, exactly, is a Tutt low and how does it affect the weather?? (I sound like SUCH a nOOb ... well, maybe that's because I AM a nOOb ... LOL)

Tropical Upper Tropospheric Trough. It is an upper low in the tropics. These things are accompanied by shear and will inhibit tropical cyclone formation or intensification if the TC is too close. Inserting "low" after TUTT is redundant.

Thanks for the explanations! I was wondering what this meant recently as well.
