Great, so now every piece of land neighboring the open Atlantic has some reasons to be concerned about Sam. :double:

Looks very my much the same to me. GFS strongly OTS. Looks to still threaten Bermuda. If it shifted SW I can’t tell.


It is weaker days 1-4
. Ok. I was referring mainly to track- which didn’t change much.

Until a high altitude recon mission is conducted and that data is incorporated into the models I place little faith in the models this far out.....MGC

Winter 2020-2021 :cold:

All observations are in Tecumseh, OK unless otherwise noted.

Winter posts are focused mainly for Oklahoma & Texas.

Take any of my forecasts with a grain of salt, refer to the NWS, SPC, and NHC for official information

That is at the 700 MB level of the atmosphere winds at the surface are 135 MPH on that run would make much more sense considering the pressure.

Levi's point (from 2 hours ago) is still valid, which is taking the mean between the GFS / EC recent runs, or TVCN.
Seems reasonable to me.
