Temperatures begin climbing in first half of the week

The very comfortable temps that were in place this weekend will be just a memory as the first heat wave of the season moves into the region during the upcoming week.

We turn the notch up on the temperatures for Monday, with highs getting into the mid and upper 80s, but the climb won't stop there.

By Tuesday, a large and formidable heat dome will set up shop within the eastern half of the country and basically remain there all week, thus providing multiple days of soaring temps.

Record highs possible this week in Tri-State Area

The long duration heat wave that expected this week is not only early, especially considering that it took until September to get our first one last year, but would be our hottest stretch of weather since July 2022.

Highs will gradually increase each day, with peak heating likely on Thursday and Friday. On these days, highs are expected to range between 95-100, and a few daily record highs may be set. Heat indices will range from 100-105 due to elevated levels of humidity.

There won't be much heat relief during the day from thunderstorms, as rain chances look very minimal this week. Even worse, overnight lows during this timeframe are likely only to dip into the mid and upper 70s. Record high minimums could also be set. This is particularly dangerous for people without air conditioning.

A break in the heat may arrive by late next weekend.
