An active weather pattern continues across the central and eastern US with one system producing accumulating snow today in the Upper Midwest and then a second system will produce rain, ice, and snow in parts of the eastern US this weekend. One upper-level wave of energy heads to the Great Lakes region today and a second one will dive to the Deep South over the next couple of days. Low pressure is going to form near the Southeast US coastline later Saturday and it will then likely grind its way to the southern Mid-Atlantic coastline by later Sunday. While there will not be any kind of real cold air in place, the chance for significant accumulating snow this weekend is certainly there for the higher elevation locations of the Appalachian Mountains where over a foot can fall.

Low pressure pushes to our northwest today and it can bring us some afternoon and evening rain shower activity along with relatively mild conditions. Another low pressure system will develop in the southeastern states on Saturday and it can grind its way far enough to the north to impact the Mid-Atlantic region on Super Bowl Sunday. With no real cold air in place, any precipitation here on Sunday is likely to be in the form of rain, but a wintry mix of rain and snow cannot be completely ruled out to the north and west of the metro region if indeed this system does indeed head this far up the coast.

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 single digits 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 in the single digits 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 showers early today, high pressure will take back control of the weather this 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 brutally cold air mass for Friday and Saturday with single digit late night lows – zero degrees is even on the table – and painfully low 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.
