Another synoptic system will cross the area late Monday through
Tuesday. Model guidance continues to show a variety of track
solutions with this system. Some runs, including the 00Z GFS and GEM
take the low center to the north and west of our region, which would
bring a brief warm-up and possible mixed precipitation or even rain
to our region. The ECMWF on the other hand takes a more southern
track, which would keep our area all snow. If the more southern
track verifies this system could be a respectable snow producer for
our region.
Regardless of the eventual track of this system, model guidance
remains in good agreement in bringing another strong push of true
arctic air into the Great Lakes and New England for the second half
of next week. 850mb temps may bottom out at -30C, which would
support near record cold across our region.
