forecast, july 11 (a little late)

july 16: pierre, sd (gem) or rapid city, sd (gfs)
july 17: helena, mt (gem) or jamestown, nd (gfs)
july 18: dickinson, nd (gem) or lethbridge, ab (gfs)
july 19: aberdeen, sd (gem) or medicine hat, ab (gfs)
july 20: nowhere (gem) or yorkton, sk (gfs)

the big story today is the absolutely huge differences between the gfs and the gem in the long range. at least one of them is going to be terribly wrong. the gfs digs a trough over the west coast while the gem builds a huge ridge over the same area. if the gem were right, chasing would be cut short because of nowhere to go. if the gfs were right, we'd be in for 5 days of fun. let's hope it's close to the gfs than to the gem. ;)
