All week long, we’ve been discussing the incoming warmup for the Eastern US, which will be affecting the region much of next week. However, before this happens we will experience the intrusion of anomalously cool air for the Northeast and Great Lakes region this coming weekend. A cut-off low detached from the general flow of the atmosphere is responsible for these expected cooler temperatures.

The cooler air is expected to begin on Friday, bringing freezing temperatures that will impact portions of the Upper Midwest and western Great Lakes region in the morning. High temperatures for much of this region will be in the 40s and 50s, but portions of the Upper Peninsula of Michigan will struggle to exceed the 30s. Meanwhile in the Northeast, widespread high temperatures will reach the 50s with patchy 60s where it’s not raining.

On Saturday, this cut-off low will center itself right over the Northeast, featuring temperatures below freezing at around 5000 feet aloft. This will translate to low temperatures in the morning, leading into the 30s and 40s for many. Widespread 30s and even freezing temperatures are forecast as far south as the Chicago area. Ahead of a cold front, which will cut the Northeast in half during the day, high temperatures will be in the 60s to the east and  50s in the west. Although those 50s are below average, they are not considered to far below it.

Sunday is expected to be the coolest day out of the weekend. From the Upper Midwest through the Great Lakes and into the interior Northeast widespread freezing temperatures are expected — and yes, wind chills will make it even cooler in the 20s and even the teens. Toward the Northeast coast, lows will be in the 40s, but due to daytime heating, temperatures will rise, yet there will be lots of cloud cover. Highs for the majority of locations will be in the 40s, however closer to the coast it will be in the 50s. Even eastern New England may avoid the cold with highs in the 60s, while Upstate and western New York are stuck in the 30s.

Now on Monday, the cut-off low will slowly move offshore. This low was originally supposed to make the Northeast cool for about 24 hours, but this low is in no rush. It is likely to keep the region cool and somewhat cloudy on Monday, especially in New England. Further west in the Midwest and Great Lakes regions, widespread high temperatures in the 60s is expected. Much of New England, New York, and Pennsylvania will only experience highs in the 50s and even the 40s in the higher elevations.

Beginning Tuesday, warmer temperatures will return to all of the Northeast.
