Looking ahead to the second half of the week, the heat is forecast to gradually ease, but never quite disappear completely.
According to AccuWeather Long-Range Expert Paul Pastelok, "The pattern through the first half of September in the East will generally favor more days with above-average warmth, than days with below-average warmth."
Even though high temperatures along the I-95 corridor will retreat back into the mid- to upper 80s, this is still 5 to 10 degrees above normal when compared to typical highs for the first week of September.

One such tropical system may even develop as soon as next week, tracking from the Caribbean towards the Gulf of Mexico.
