BOSTON (CBS) – After the storms exit Monday, our attention will turn to the building heat across the eastern half of the country for the mid-to-late portion of this week.

Temperatures on Tuesday and Wednesday will be quite warm, but bearable in the mid-to-upper 80’s with moderate humidity levels.

The heat could reach dangerous levels on Thursday and Friday, as temperatures will soar well into the 90’s, and potentially close to 100 degrees on both days.

The humidity will also be nasty, with dew points expected to be 70-to-75 at least, just about as high as it gets in New England.

Combine the dew points in the 70’s with heat in the upper 90’s and the Heat Index (the “feels like temperature”) will be well over 100.

It is possible we could hit 100 both Thursday and Friday and not even get a record!

The record highs for those two days are 102 and 103 respectively.

We have reached 100 just a little over 20 times in our recorded history.

This works out to an average of about once every 5 years or so.

The last time we hit 100 was just last year on July 6th (one of 25 days above 90 last year).

There are also some signs that the extreme heat could persist into this weekend, but it is too early to tell whether a cold front will drop down from Canada early Saturday or not, potentially proving some relief.
