I'd like to know what the water temp of the Gulf Stream is, off the coast of New England.

Warm water will fuel the hurricane engine and cooler water will dampen the hurricane engine.

As it is now, we've had night temps in the mid 50's and it is supposed to be in the low 40's tonight, in Illinois.

The water in the Illinois River is giving up it's heat rapidly as our nightly bouts with fog will atest to.
