UPDATE. (Issued 912 PM CST Tue Jan 18 2022)

Arctic front over western WI will continue to race east and cross southern WI through the overnight hours. Gusty southwest winds ahead of the front will turn to the northwest and gust to 30 to 35 mph for a few hours into Wednesday morning. A period of stratus associated with the cold air surge immediately behind the front will spread across southern WI overnight. The cloud area is only 60 to 90 miles wide so clearing should return with the blustery, cold northwest winds later tonight into early Wednesday. More clouds will likely return later on Wednesday. Bumped up overnight temperatures a couple degrees most spots.

SHORT TERM. (Issued 310 PM CST Tue Jan 18 2022)

Tonight through Wednesday night:

A low pressure system across the northern Great Lakes will continue to push east. While precipitation outside of some flurries along the front is not expected we should expect some breezy winds from the south initially then turning to the west northwest behind what will be a fairly strong front. Following this front we will see temperatures drop fairly significantly. Temperatures will continue to drop for a good portion the day Wednesday. Ultimately highs will only reach the low to mid teens. Wednesday morning will be pretty chilly with a northwest breeze likely bringing wind chills into the negative single digits across much of the CWA.

Some models suggest as the strong high pressure pushes in from the west that we could see some flurries Wednesday early morning through the late morning given some low level moisture which will be in the DGZ given how cold it will be, thus some flurries could be possible.

Overnight Wednesday the high will further push into the region and we will expect to remain dry with clouds clearing out and allowing temperatures to drop to the low single digits to negative single digits with wind chills as low as the negative mid teens.

Kuroski

LONG TERM. (Issued 310 PM CST Tue Jan 18 2022)

Thursday through Tuesday:

Thursday will very likely be the coldest day of this cold spell with temperatures likely not escaping the single digits for a large portion of the CWA. The surface high will start to the west and push over the area likely bring mostly clear skies and light winds with overnight lows likely dropping back into the low single digits to upper negative single digits, though lights to calm winds should prevent wind chills from falling to Advisory thresholds.

Friday the strong high will weaken and push east of the CWA as another cold front will push toward the CWA overnight. This time we may see some precipitation with it by Saturday morning. This would certainly be snow but given limited forcing there is some uncertainty. However the upper level shortwave and some low level WAA should provide enough forcing to bring some snow showers given a period of moist low levels in the morning/afternoon Saturday. Being a very quick hitter this would likely not amount to much in the way of accumulations.

Sunday will feature another clipper system though there appears to be much more uncertainty with this system at the moment. It ultimately depends on the track of the weak low and the strength of the high to the north. This will feature perhaps a weak shortwave in the upper levels but will likely feature some forcing with the low pressure as well as some WAA in the low to mid levels. Where this clipper ends up will likely bring some snow to that region.

Beyond this weekend there will be a chance for another clipper Monday. Still plenty of uncertainty with the track of this system but some models suggest deeper moisture and stronger forcing. While this would still be expected to be a quick hitter the QPF trends indicate potential for higher snowfall amounts. Certainly a system to watch going forward. With the passing of that system we will be headed for another significant cold spell as another strong high barrels into the region.

Kuroski

AVIATION. (Issued 912 PM CST Tue Jan 18 2022)

Area of low clouds associated with initial burst of cold air advection behind Arctic front poised to push across southern WI for a time overnight. The area of low clouds is only about 70-100 miles wide so perhaps only a few hours of MVFR conditions can be expected. Thinking more low clouds will return later on Wednesday with secondary surge of cold air. The ongoing gusty southwest winds will turn to the northwest after an Arctic front passes overnight, with gusts of 30 to 35 kts.

Kavinsky

MARINE. (Issued 912 PM CST Tue Jan 18 2022)

Gusty south to southwest winds to 40 knots will diminish a bit ahead of an approaching Arctic front over western WI, attached to low pressure over central Lake Superior. This Arctic front will cross Lake Michigan later tonight with increasing west to northwest winds in its wake. Occasional gale force gusts to 35 knots will linger through the morning across the northern lake and at least through 12Z in the south. Hence extended the Gale Warning for each lake segment 6 hours. Left the Small Craft Advisory for the nearshore waters in place, but a few gale force gusts will be possible towards the open water later tonight into early Wednesday.
