When's the last time the GFS actually showed a tropical storm out in the medium to long range? And I'm not counting the CAG-based storms it always seems to invent.

The GFS seems completely unable to develop a storm from a tropical wave that has not yet exited Africa. I'm not sure why.

I am not liking this 500MB look by the GFS approaching the climatological peak, but it is in the super long-range:

Seriously. Imagine the impact if THAT pattern verifies and was largely in place for several weeks in an over-active (and West based) season that we've seen thus far?

Hoo boy that's a scary pattern, hopefully we don't catch up on the relative lack of Caribbean cruisers in recent years all at once...

Not a meteorologist, in fact more of an idiot than anything. You should probably check with the NHC or a local NWS office for official information.

That's why that wave approaching the African coast and developing on many ensemble members is concerning.

Sure thing, but something has to develop first in order to take advantage.

The GFS sends two consecutive AEW's all the way across the basin into the Bahamas with absolutely no development at peak season

A ridge that strong would send anything west into Central America or Mexico, maybe southern Texas. Weird seeing a ridge on the GFS 300+ hrs. out as opposed to a trough.

GFS finally showing something in the MDR. Given it's tendency this year (and if it persists on the runs) could be a sign of a multiple storm outbreak in September--consistent with what the longer range models have been showing.

Saved for posterity, in case it stops for several runs.

If GFS is developing a major after all the epic fails this year its definitely time to pay attention
