Temperatures are on a rollercoaster ride this week in the Midwest and Northeast, as it gets hot and humid, giving way to another cooldown. But this temperature decline could not last long, as the hot weather in September could be another first week of comeback.

In addition, an excessive heat warning is posted in St. Louis, where the peak afternoon heat index is up to 105 degrees every Tuesday.

The Northeast will be a warming alert for part of the mid-Atlantic States, New York and New England, including the entire New York City Tri-State area and Philadelphia Metros. Excessive heat warnings for more dangerous heat indices are posted for the Boston and Hartford metro areas.
