TD Nine today; "Isaac" tomorrow?
Here we go!
It's "game on" for hurricane forecasters in the Atlantic and the southeast USA.
TD Nine has formed, and all indications are she will become Hurricane Isaac in the next 48 hours.
The official NHC forecast and suite of model tracks favors putting Isaac near Cuba by sometime Sunday. That's a position which usually poses a threat to the USA mainland as hurricanes recurve to the north.

The GFS model takes a potential "Isaac" right up the center of Florida next Monday night & Tuesday morning.

Keep in mind that model forecast track errors are still around 400 to 500 miles 6-7 days out. It;s still too early to say Isaac will hit Florida...it could veer out into the Atlantic east of Florida, or continue west into the Gulf. If Isaac slows over the eastern mountains of Cuba the circulation could also get ripped apart by higher terrain.

But if Isaac tracks south of Cuba, then curves north over low lying western Cuba it could be a real threat to Florida.

State Fair Forecast: Partly wet & thundery?
I've been hoping I'm wrong about this now for almost a week, but with less than 48 hours to go it still looks potentially wet for the opening weekend of the 2012 MN State Fair.
