Discussion
The first extended heat wave of the summer in the Mid-Atlantic region will break today with the arrival of a frontal system that will generate showers and perhaps a strong-to-severe thunderstorm or two. It’ll remain pretty hot today though not as excessive as the past weekend and it’ll continue to be very humid and quite breezy. Much more comfortable air will arrive in the region by tomorrow with temperatures likely confined to the low-to-mid 80’s for highs on Tuesday afternoon…actually below-normal for this time of year. The front stalls out nearby on Tuesday and its proximity for the remainder of the week will keep it quite unsettled here to go along with seasonal temperatures. One final note, the high temperatures for Saturday and Sunday in the I-95 corridor were as follows: Philly: 98/99 degrees, DCA: 96/94 degrees, Central Park (NYC): 95/95 degrees and LaGuardia Apt. (NYC): 97/98 degrees.
