All model guidance is just that, guidance. It is the responsibility of the forecaster to take that information, make it better, and to appropriately communicate the forecast to the users.

Fervent supporter of the idea to make GFS output beyond hour 168 proprietary! Anyone wanting to post/share/tweet/etc GFS output beyond day 7 should have 1) a limited set of graphics available with the option to 2) contribute a nominal fee to get a full suite of products while improving future GFS output. #EURObusinessfor-the-win

12z H3 winds comparison breath 3km NAMand SPC meso.

Interesting that the jet streak in Montana is stronger in the SPC meso, but the Dakotas one is stronger in the model. Not sure if it means anything.

Edit: also looks deeper INVOF the Oklahoma panhandle

These systems often seem to have little surprises thrown in with the energy coming from inland and a storm offshore , might be able to get a tad of interaction to fill the precip shield in s bit over land between the 2. Will have to wait and see I guess.....

Looks pretty similar for the coastal, and more precip with the inland energy that modeled.
