.DISCUSSION...
Issued at 235 PM EST Sat Feb 7 2026
- Light Snow Tonight
A weak shortwave trough is shearing out as it tracks quickly
southeast tonight. Model soundings show the column moistens up
this evening and light snow overcomes low level dry wedge by late
evening. F-gen banding currently seen across northern Wisconsin
should translate SE and clip roughly the western third of the
forecast area overnight. Accums generally a dusting to an inch
with potential for 1 to 2 inches over a narrow area where banding
occurs. The moisture and lift dissipate by Sunday morning with
fair and cold weather into early Monday.
- Clipper Goes North of Lower Michigan Monday
A northern stream shortwave trough and clipper tracks north of
Lower Michigan Monday into Tuesday. Light snow could extend into
the northern forecast area by Tuesday, but moisture profiles look
rather dry and chance of snow is low there. Temperatures moderate
during this time before cold air returns for mid-week as the
clipper moves east.
- Weekend Storm Potential
Longwave pattern becomes more active by the end of the week with
the potential for a low to be moving out of the Plains and either
towards the Great Lakes or across the Ohio Valley. Ensemble
spread is quite large at this point but there is enough of a
signal to watch the evolution closely next week.
