Heavy Great Lakes Snow through Friday; Extreme Cold and Potential for Major Winter Storm Late Week into this Weekend

Multiple clipper systems will bring cold temperatures and enhance lake-effect snow downwind of the Great Lakes. An arctic blast will bring frigid temperatures accompanied with gusty winds that may lead to dangerous wind chills beginning in the Northern Plains Thursday before expanding to the South and East. An expansive winter storm will start Friday in the Southern Rockies/Plains and Mid-South. Read More >

.AVIATION /06Z WEDNESDAY THROUGH SUNDAY/... VFR conditions will continue through Friday morning as surface high pressure shifts offshore and a series of moisture-starved fronts push through. The biggest concern for aviators will be the wind, especially heading into the midweek period. Expect southerly winds to gust 20 to 30 kts outside the mountains as a warm front lifts through this afternoon. These winds will slacken a bit tonight with LLWS likely this evening given 30-50 degree directional shear and 40-50 kts at 2kft ALG. Winds will increase again Thursday ahead of an approaching Arctic cold frontal boundary. Expect 15 to 25 kt gusts Thursday out of the west and southwest. Winds will turn back to the northwest Thursday night into Friday with gusts less than 15 kts expected. A light rain/snow mix could impact terminals across central and southern VA Friday although confidence is low at this time. Skies begin overcast on Saturday morning, but any snow should not commence until around Saturday evening. As ceilings lower through the day, expect restrictions to kick in ahead of this swath of snowfall. At that point, expect a lengthy period of IFR caliber conditions Saturday evening/night and into all of Sunday. Given the degree of cold air in place, this should be all snow to start, though there are hints of an icy mix by later Sunday, especially south and east. Initial winds will be out of the northwest on Saturday morning before shifting to the north to northeast through the day as Arctic high pressure builds across New England. For Sunday, winds largely remain northerly as low pressure eventually develops off the North Carolina coast later in the day. Gusts each day over the weekend should top out around 10 to 15 knots, perhaps slightly higher in the metros. AVIATION...BRO/DHOF/EST Update as of: 203 AM EST Wed Jan 21 2026
