90-Degree Heat to Return Soon to the Mid-Atlantic

Labor Day is known as the unofficial end to summer. However, 90-degree heat returns to the mid-Atlantic after the holiday weekend.
The area of high pressure that delivered Sunday's nice weather to the mid-Atlantic will shift offshore on Labor Day. Warmer air will get drawn northward, not just over the mid-Atlantic, but also over the Ohio Valley and much of the Great Lakes.
Monday's temperatures will exceed Sunday's highs by roughly 10 degrees in the Ohio Valley and Great Lakes. That change in high temperatures will be closer to 5 degrees across the mid-Atlantic.
Additional warming Tuesday will return 90-degree temperatures to the mid-Atlantic's Interstate-95 corridor from Richmond to Washington, D.C., to Philadelphia. Similar highs are also expected in cities along the Ohio River, such as Cincinnati.
New York City will warm into the mid-80s Tuesday as 80-degree warmth spreads northward to Burlington, Vt., and Portsmouth, N.H.
The warmth expected Tuesday will come after all of the major mid-Atlantic cities experienced a record warm meteorological summer, defined as the period from June to August.
Baltimore could set yet another heat-related record Tuesday. That day should be the city's 55th 90-degree day, marking this year as having the most such days out of any year in recorded history.
The upcoming warmth across the mid-Atlantic and Northeast will not be accompanied by high humidity.
That lack of moisture, however, will prevent a cold front from producing significant rainfall across both regions, outside of northern New England, Tuesday into Wednesday.
Rainfall would be welcome, especially over the mid-Atlantic. The United States Drought Monitor reported last Thursday that the corridor from western Maryland to southeastern Virginia is suffering from a severe drought.
The cold front will still prove beneficial by allowing more comfortable air to return later in the week.

The "Dead of Winter," the one-month period when normal temperatures reach their lowest levels, has come to an end for much of the United States. Some people may find it odd that the "Dead of Winter" does not encompass the darkest day of the year (the first day of winter). That is due to a seasonal lag in temperatures. More heat continues to be lost than is gained from the start of winter until this time of year.
