13 hours into the epic drive from Kansas City to Great Falls, Montana has landed us in Casper, WY for the moment as of noon MDT. Incredibly hot airmass has pushed well into the interior with a noon reading of 95 degrees in Casper, and highs of 110F are possible over western Kansas today. Wow! Our thought process hasn't changed since early this morning with a plume of quality moisture (characterized by mid-upper 50F dewpoints) funneling westward through Montana, beneath steep lapse rates and strengthening mid-upper flow. Powerful trough that will bring us a string of opportune days remains off the Oregon coast per early afternoon water vapor imagery. Forecast soundings and shear profiles still look fantastic for rotating storms across western Montana early this evening as the increasing moisture/daytime heating couples with strong, veering flow with height. Really the only lingering concern is with the placement of synoptic scale lift. The HRRR/RAP hold the lead wave further west, yielding an arc of supercells along the MT/ID border across the higher terrain. Without a 120 mph speed limit, this is simply unreachable, so we remain hopeful of additional evening development 00-03Z toward GTF. Already one dust devil across the rolling hills and Cu development over the higher terrain to the north. Stay tuned! - Bookie
