SHORT TERM. (Issued 235 PM CST Thu Jan 20 2022)

Tonight and Friday:

Clear skies will continue tonight into Friday, as high pressure moves through the region. Temperatures will likely fall pretty quickly this evening as winds become light and variable. Overnight lows will be in the single digits below zero for most of the area, though some locations near the lake may remain just above. Despite the cold temperatures, the lack of wind will mitigate any wind chill concerns, so no Advisory will be needed for tonight.

Winds turn southerly on Friday, with temperatures reaching the mid to upper teens. Clouds will increase Friday afternoon as the next clipper approaches.

LONG TERM. (Issued 235 PM CST Thu Jan 20 2022)

Friday night through Thursday:

The first of three systems of interest will sweep across the area Friday night, with a band of light snow moving through the region. Amounts currently look to be around a half inch for most locations, though limited moisture over far southeastern Wisconsin may keep amounts closer to a trace.

Lingering flurries should end Saturday morning, before another wave arrives Saturday night. This system is a bit stronger than the one from Friday night, and will likely bring with it a band of slightly heavier snowfall. There's still some uncertainty with the exact track of the surface low and the heavier snow band, but at this point it looks most likely to affect the southwestern half of the forecast area. The bulk of the snow with this system will fall late Saturday night, though some may linger into the morning hours on Sunday.

After reaching the 20s on Saturday, temperatures look to fall back into the teens for Sunday, as high pressure quickly moves through.

By late Sunday night, the third system is expected to be diving southeast across the Dakotas. While guidance is in good agreement with most of the area seeing at least some snow with this third system, there is a lot of uncertainty with the system's overall structure, as well as strength and placement of the highest area of QPF/snowfall. There are some timing differences as well, with the EC solutions generally about 12 hours faster than the GFS/GEFS.

Also of note, the elongated, more southerly area of low pressure depicted in many of the GFS solutions would likely result in a period of northeast winds, and thus lake effect snow potential, continuing into Tuesday. The more compact, northerly EC solutions favor a northwesterly, offshore flow.

Cold high pressure is expected to build into the region behind the Monday/Monday night system, with generally quiet conditions mid to lake week.

Boxell

AVIATION. (Issued 235 PM CST Thu Jan 20 2022)

VFR conditions and mostly clear skies will persist through mid day Friday, before high clouds start to build into the area Friday afternoon and evening. Winds will be light and variable tonight, becoming southwesterly Friday morning. Speeds will pick up slightly Friday afternoon as a system approaches from the northwest.

Boxell

MARINE. (Issued 235 PM CST Thu Jan 20 2022)

High pressure moving through the Great Lakes will keep winds relatively light tonight and Friday morning. Winds pick up Friday afternoon and especially Friday night, with southwest gales expected over most of the open waters Friday night and Saturday morning. Gales will initially develop across the north half early Friday evening, and quickly expand to the south Friday night. A Gale Watch is in effect for all of the open waters for this time period. For the nearshore waters, gales will likely remain over the open waters, but a Small Craft Advisory will likely be needed.

Winds turn northwesterly Saturday and Sunday as another clipper moves through the region. A third system will approach Sunday night and Monday, with a brief period of southerly flow possible ahead of the surface low, followed by northerly winds behind.
