I'll reiterate this from kbuf afd yesterday..
The GFS is again
faster with the next trough coming into the Great Lakes, and again
appears too fast when compared to ECMWF/GEM solutions and ensemble
means. Given this, kept the Monday through Tuesday period dry and
turning gradually cooler.
And from this morning afd..
As a new longwave trough digs into the Inter-Mountain West Monday
and Tuesday...a broad ridge will become established over the eastern
half of the Conus. Expansive sfc high pressure beneath this ridge
will become centered over the Great lakes region...and this will
support fair dry weather across our region with temperatures likely
averaging a few degrees above late October normals.
