.DISCUSSION...
Issued at 229 PM CST Sat Feb 7 2026

Mid-level cloud cover will continue to increase across the area
into this evening in association with our next quickly
approaching low amplitude shortwave impulse riding the northwest
flow into the region tonight. While much of the area will see
cloud cover around tonight, we do continue to monitor the
potential for a quick hit of light accumulating snow late
tonight across a small portion of the area. It is important to
note that most areas will not see any snow as a result of this
impulse tonight, owing to the very dry low-level airmass in
place. Instead, we are watching areas generally along a narrow
north-northwest to south- southeast oriented corridor that
extends from southeastern WI and far northeastern IL (especially
in close proximity to Lake Michigan) southeastward into parts
of northwestern IN. Forecast guidance continues to insist that
top-down saturation will occur in this corridor and support a
short period (2-4 hours) of snow later tonight. This certainly
seems plausible since this is also the general region in which a
transient band of frontogenesis is favored to develop and
support some enhanced forced ascent. We have thus continued to
confine chance to low end likely POPs (30-60% chance) in this
general area overnight. The short duration of snow should result
in light amounts of a coating to perhaps locally up to an inch.

A large scale weather pattern change is slated to take place
into the first portion of the upcoming work week. This will
occur as the persistent high amplitude ridging over western
North America begins to deamplify and transition the upper-level
pattern across most of the country into a more quasi-zonal flow
pattern (west-to-east) for a period next week. Overall, this
will set the stage for a milder airmass across our region this
week as the very cold airmass remains north of the area.

The threat of precipitation also looks to remain low (
