Temperatures to plunge this week after brief taste of summer shatters more than 200 record highs

More than 200 record-high temperatures were broken across the US from the Southwest to the Northeast last week, but the brief taste of summer has come to an end as temperatures are expected to tumble back to average or below average in the week ahead.

According to the FOX Forecast Center, the warm temperatures will be confined to the Northeast and New England on Sunday while areas of the Upper Midwest were seeing cold temperatures as a storm system brings snow to that region.

Record-breaking temperatures for the US

Last week, an area of low pressure brought rain and stormy conditions to the Southeast, which helped to keep temperatures cooler while areas to the north and northeast saw record-breaking heat.

Denver, for example, saw a high temperature of 85 degrees last Wednesday, about 21 degrees warmer than average. Then on Friday, temperatures fell back below average, and the city saw a high temperature of 55 degrees – a 30-degree temperature drop.

Snow was also reported in Denver on Friday.

The extreme temperature swing was also evident in Minneapolis, which saw a high temperature of 83 degrees on Friday and is only expected to reach the mid-30s on Sunday.

In the northeast, Buffalo, New York, saw temperatures nearly 30 degrees above average on Friday, but by Tuesday, those are expected to fall back into the low 40s.

Forecast for the start of the week

As we enter the new workweek, the temperature change will be noticeable for millions of people across the country’s eastern half.

On Sunday, Milwaukee is expected to see a high temperature of about 54 degrees, but when the cold front marches through, it will get much cooler.

By Monday, Milwaukee will see a high temperature of only about 40 degrees but will jump back to about 52 degrees on Tuesday.

Chicago is expected to see a high temperature of about 45 degrees on Sunday and cool down into the upper 30s by Monday.

The Windy City is also expected to see snow on Monday.

New York City will get in on the cooldown later in the week.

The Big Apple is expected to see a high temperature in the upper 60s on Sunday and low 70s on Monday.

On Tuesday, New York is only expected to reach the upper 50s for daytime highs.

The Boston Marathon is being held on Monday, and temperatures along the 26.2-mile race route will be much cooler than the region saw last week.

In Hopkinton, where the Boston Marathon begins, temperatures will be in the upper 40s at the start of the race and a high temperature of about 61 degrees is expected later in the day.

At the finish line in downtown Boston, the morning is expected to be about 48 degrees and see a high temperature of about 55 degrees with showers expected.
