An active weather pattern continues across the nation with severe weather a threat later today in the south-central US/Lower Mississippi Valley and accumulating snow on the table later tomorrow across the Upper Midwest. Another system will dive to the southeast over the next few days and reach the southeastern states by early this weekend. Low pressure is likely to form near the Southeast US coastline on Saturday and it can grind its way far enough to the north to impact the Mid-Atlantic region on Super Bowl Sunday. While there will not be any kind of real cold air mass in place, the chance for snow or sleet is on the table in higher elevation locations of the Carolinas and Mid-Atlantic region and potentially in other “dynamically cooled” regions.

It’ll turn milder today with some sunshine and then low pressure heads to our northwest on Thursday bringing with it a warm frontal system to our area and a chance for some rain. Another low pressure system is likely to develop this weekend in the Southeast US and it could make it far enough to the north to impact the Mid-Atlantic region by Sunday with rain or perhaps even a wintry mix of rain and snow.

High pressure will remain in control for another day in the Mid-Atlantic region, but a frontal system can bring us a shower or two by late tonight. Low pressure will then move from the central US to the Great Lakes and it can bring us rain on Thursday along with mild conditions. Another low pressure system will follow close behind and it can bring some rain here early this weekend as it turns colder in the Mid-Atlantic region.

A weak cold front passed through the region last night and high pressure will build through mid-week. Low pressure will then move from the central US to the Great Lakes and it can bring us rain on Thursday along with milder conditions. Another low pressure system can bring us some rain from Friday into Saturday and then it’ll turn colder this weekend.

An Arctic front will sweep through the region early today and this will usher in severe cold for the region for the next 48 hours. The winds will pick up noticeably as well leading to painfully low wind chill values in this two-day Arctic blast. Temperatures should bottom out in the lower teens later tonight and persistent stiff NW winds will make it feel much colder than the actual air temperatures. Temperatures will moderate noticeably by Sunday afternoon as high pressure pushes offshore and a low-level southwesterly flow of air develops in the Mid-Atlantic region.

An Arctic front will sweep through the region early on Friday and this will usher in severe cold for Friday, Friday night, and Saturday. The winds will pick up noticeably as well leading to painfully low wind chill values in this upcoming two-day Arctic blast. Temperatures should bottom out near the 10 degree mark later Friday night/early Saturday morning and persistent stiff NW winds will make it feel even much colder than the actual air temperatures. Temperatures will moderate noticeably by Sunday afternoon as high pressure pushes offshore and a low-level southwesterly flow of air develops in the Mid-Atlantic region.

After the threat of snow early today, high pressure will take back control of the weather by afternoon and clearing skies will develop in the Mid-Atlantic region. After a moderately cold day on Thursday, an Arctic front will head in this direction and blast through early Friday morning. This frontal passage will usher in a very cold air mass for both Friday and Saturday with late night lows in the lower teens along with much lower wind chill values.

It won’t be a big deal, but compared to the snow (or lack thereof) so far this winter season, the coating to an inch or so of snow that can fall late tonight/early Wednesday in the DC-Philly-to-NYC corridor may seem like quite a bit. Low pressure that is now creating significant icing problems across Arkansas and Texas will move along a stalled-out frontal boundary zone and it should make it far enough to the north to produce some snow in the Mid-Atlantic region from later tonight into early Wednesday. After a moderately cold day on Thursday, an Arctic front will blast through the Mid-Atlantic/Northeast US by early Friday and this frontal passage will usher in a brutally cold air mass for Friday and Saturday. In fact, single digit lows are likely on Friday night all the way down to the Philly metro region and zero degrees is on the table for New York City. In addition, wind chills will cause some pain in this short-lived, but very impressive Arctic blast.

Colder air will push into the region today following the passage of a slow-moving frontal system that will then stall out just to the south of here. A wave of low pressure will push along the stalled-out frontal boundary zone later tonight and it could produce a wintry mix in the evening and then some snow late tonight and early Wednesday. After a moderately cold day on Thursday, a strong Arctic front will blast through here on Friday morning and it’ll usher in two-day shot of some very cold air with painful wind chills and lows in the low-to-mid teens by early Saturday.

There is a slight chance for rain, ice and/or snow tomorrow and tomorrow night and maybe a second chance later in the week, but perhaps the biggest story of the week will be the change to cold. In fact, there is a good chance for some very cold conditions here from Friday into Saturday with the lower teens on the table later Friday night. A cold front will slowly works its way through the region today and then stalls out just to the south of here. A series of low pressure systems will ride along the frontal-boundary zone at the same time colder air seeps in from the northwest.
