Midwest, Northeast brace for abrupt spring cooldown

Big Chill On the Way

by Linda Lam, Weather Channel

Changes are sweeping through the Midwest and Northeast in the way of a cooldown, so hopefully you haven't put away your jacket yet after enjoying a taste of spring this past week.

Noticeably cooler temperatures will develop this week due to an upper-level trough that will slide into the Midwest dragging modified Canadian air from the northern Plains to the Northeast. This upper-level trough will make slow progress eastward which will allow the cool temperatures to remain in place.

The trough will likely begin to shift off the East Coast midweek, but a northwest flow in the higher levels of the atmosphere will keep the cooler air in place.

A Taste of Spring

The Midwest and Northeast were stuck in a pattern of below-average temperatures for much of this year, until this past week, when mild air and above-average temperatures settled in. Temperatures climbed into the 60s and 70s from Minneapolis to Chicago to New York. Even Marquette, Michigan, saw highs in the 60s almost every day this past week through Friday (except Monday when the high only reached 56 degrees).

Chicago saw their warmest temperature so far this year on Friday with a high of 78 degrees. Indianapolis also saw its warmest highs so far in 2015 on Friday and Saturday, topping out at 76 degrees.

Check out some gorgeous spring flowers to brighten what may be a dreary day:

High temperatures in Minneapolis reached the mid-70s at times this past week, which is closer to the average high temperature in late May or early June.

Buffalo also had a taste of summer when the thermometer reached 78 degrees this past Monday, which is the average high temperature in late June.

Although temperatures in Boston climbed into the 60s, the city still hasn't seen 70 degrees this year -- and it's unlikely to happen in the near future. The average date for the first 70 degree day is April 9.

How cool will it be?

You'll begin to feel the colder temperatures early this week. Let's take a look at the forecast details below.

(FORECAST: International Falls | Detroit | New York)

Early Week: The cooler air really begins to take hold with highs below-average in the Upper Midwest and Great Lakes. The greatest departures from average will be found in Minnesota, northern Wisconsin and much of Michigan, where high temperatures will be 5 to 20 degrees below average.

(FORECAST: Minneapolis | Chicago | Boston)

Late Week: By Thursday, below-average temperatures will stretch from eastern North Dakota to the Northeast and Mid-Atlantic, with the eastern Great Lakes most likely seeing the largest departures from average where highs may be as much as 15 degrees below average. Highs will remain below average in the Great Lakes, Northeast and Mid-Atlantic through Friday.

(FORECAST: Marquette | Buffalo | Washington, D.C.)

For much of the week ahead, high temperatures will be in the 40s and 50s, with 60s from the northern mid-Atlantic to the mid-Mississippi Valley. Portions of northern Minnesota and the northern Great Lakes will find high temperatures stuck in the 30s at times.

Low temperatures will typically be in the 30s and 40s, with lows dropping into the 20s from northern Minnesota to the Upper-Peninsula of Michigan beginning Tuesday or Wednesday morning.

Along with the cooler temperatures comes the risk for rain, as low pressure remains over eastern Canada, allowing disturbances to bring the chance of showers, especially through midweek. Some snow may even mix in at times from northern Minnesota into the Great Lakes.
