A significant weekend snowstorm is winding down as it exits the Northeast, but brutally cold air is now arrived in its wake. We’re also tracking several other storms that will impact the US and more in this week’s 5 Things to Watch.

Lingering Snow Showers:

After more than a foot of snow fell across a widespread area of the interior Northeast this past weekend, lingering snow showers will remain in place across most northern sections. The cold air and unfrozen Great Lakes will also provide conducive conditions for lake-effect snow off of Lakes Erie and Ontario, adding even more snow to the hefty pack. Only a few inches of snow is expected to fall Monday before shutting off Monday night, but the wind, cold temperatures, and snow mixed together will surely make for brutal conditions in this part of the country.

Extreme Cold:

Extremely cold temperatures have settled into the Midwest and Northeast thanks to a large trough of low pressure, allowing for the brutally cold air to funnel in from Canada. Widespread low temperatures of sub-zero and single digits will be in place both Monday and Tuesday away from the coast. The winds will make it feel even cooler. Even during the day — especially on Monday — high temperatures will struggle to surpass the zero degree mark in several areas while the remainder of the Northeast deals with highs only in the single-digits and teens. Thankfully, temperatures will return to above average levels mid- to late- week for most of the region.

More Snow for West:

Another storm system currently moving into the West Coast will be responsible for more rounds of heavy snow across the various mountain ranges, including the Sierra Nevada. Across parts of these mountains, over two feet of accumulation will be possible, with localized areas of over four feet. Unlike last week’s storm, this will primarily be a snow-maker, with limited rainfall. This will also be a quick-hitter with most of the precipitation ending by Tuesday.

More Snow for Northeast?

So is more snow in the forecast for the Northeast? Signs are hinting at that potential both late-week and this coming weekend but the forecast remains highly uncertain at this time. Head meteorologist Joshua Feldman discusses one of the possible outcomes in this week’s Sunday Storm:

Depending on how far south the clipper system penetrates, a snowstorm could be the result. The clipper needs to reach the Atlantic coast to rapidly intensify as winter storms feed on strong thermal gradients, like that between the warm ocean and bitter cold land. If it does reach the mid-Atlantic coast, it would undergo rapid intensification and a potentially significant coastal snowstorm would ensue. Conversely, if the clipper tracks too far west, it may never reach the Atlantic before being directed into the Canadian Maritimes. A light snowfall across the Northeast would be the outcome, with accumulating snow possibly reaching the coast.

More Cold for East Next Weekend:

Along with this next potential snowstorm, as mentioned above, there will be another round of very cold air that will likely be involved. As this storm system interacts with a trough of low pressure, it will aid in drawing down very cold air from the north, therefore ushering in another round of well below average temperatures. Highs will be below freezing for most areas in the Midwest and Northeast beginning this coming weekend, meaning that temperatures will generally be 10 to 25 degrees below average.
