.DISCUSSION...(This evening through Wednesday)
Issued at 259 PM CST Wed Jan 19 2022

Key Messages:

- Wind chills will once again fall 25 below to 30 below through
tomorrow morning.

- Multiple weak clippers are expected Friday through Monday.
The highest chance for snow is Sunday/Monday.

Strong Canadian high pressure will continue to sink southward
through tomorrow across the region, setting the stage for another
frigid night under clear skies. Winds won`t really weaken until
tomorrow afternoon as the aforementioned high settles in overhead,
so hazardous wind chills will again be a concern overnight. Highs
will struggle to get above zero with wind chills slowly improving
into the late afternoon as winds diminish.

Temperatures Friday will be considerably warmer with WAA working in
on the backside of the high with highs in the 20s. A trough will
approach the area by Friday afternoon, bringing the first of a few
chances for light snow through the weekend. QPF totals have been
lowered from previous forecasts, resulting in an inch of snow or
less for eastern Minnesota and western Wisconsin late Friday
evening. Winds ahead of this system will be quite breezy out of the
south Friday before weakening somewhat overnight and becoming
northwesterly. Increased winds Friday morning through Saturday
morning with gusts topping out around 25-30kts across western
Minnesota.

The majority of Saturday will be dry before another clipper swings
through during the evening and overnight hours. Again, precip
appears to be light with little moisture for this system to tap
into, so up to another inch of snow is possible, this time more
widespread across the CWA. A third and more promising looking
clipper will move in late Sunday into Monday. Moisture increases
ahead of this system, which will likely make this the most efficient
snow producer of the trio of clippers. It may also end up being the
most impactful timing wise, with snow lingering into Monday
afternoon coupled with gusty winds.

Beyond Monday, temperatures once again fall into the single digits
under high pressure.
