.DISCUSSION...
Issued at 229 AM CST Sat Feb 14 2026

Abundant dry air in place has kept dense fog from forming across
much of the area this morning. Instead, some patchy fog was noted
across some of the region with only modest reductions in
visibilities. Therefore, will drop the Dense Fog Advisory across
the region this morning as widespread dense fog is not anticipated
for the rest of the morning. Patchy fog is also expected tonight
into Sunday morning; however, it does not appear that widespread
dense fog is anticipated.

Otherwise, above normal temperatures to continue through the
middle of next week. It appears Monday will be the warmest day
ahead of a weak cold front, with a 40-80% chance of reaching 50
degrees south of a Wausau to Sturgeon Bay line. There is even a
10-20% chance of reaching 60 degrees in Waushara as well as
southern Wood and Portage counties. The record or near record
warmth comes to an end Monday night behind a weak cold front, with
highs on Tuesday in the middle 30s to lower 40s. These readings
are still about 10 degrees above normal for the date.

A potent system is expected (60-90% chance) to bring rain, snow
or a wintry mix to the area Tuesday night and Wednesday.
Precipitable water values are near record for the date. Also, an
east-west band of heavier QPF has been focused across northern
Wisconsin where 0.75 to 1.25 inches of QPF is possible. Travel
may be impacted by a wintry mix or accumulating snow across
this region depending on precipitation type.

There is another system that could (30-50% chance) impact travel
in the Thursday to Friday timeframe, with the potential for an
accumulating snowfall. This system is colder with a better chance
for snowfall, although there is less moisture to work with so the
potential for higher end snowfall amounts is lower.
