20/00Z run

Day 1 (June 28)
GFS: Coronation, AB
GEM: Red Deer, AB

Day 2 (June 29)
GFS: Coronation, AB
GEM: Coronation, AB

Day 3 (June 30)
GFS: Brandon, MB

Day 4 (July 1)
GFS: Dickinson, ND

Day 5 (July 2)
GFS: Calgary, AB

This is really changing like crazy! For example, the day 1 GFS solution has had as a "target" Calgary (twice), Saskatoon (twice), Banff and Coronation.

Wanna really see how much model forecasts change, especially in the long range? Check out this 250 mb panel comparison (from CoD); both panels are valid for the same time (29/00Z) but are from runs 12 hours apart. Note the location and orientation of the jet stream west of Vancouver Island in each panel. 'Nuff said.




On a side note, it looks like I will be going out for a chase with JH on Monday and Tuesday. Here's what Monday's forecast sounding looks like (courtesy wxcaster.com).

Where is this sounding forecast for?

That was for Fargo. The new NAM has it a little outside of Fargo, but in the same general area.
