Discussion
It has been cooler-than-normal so far this month in much of the Mid-Atlantic region with some spots in the I-95 corridor recording four consecutive nights with overnight low temperatures in the 40’s – something that hasn’t happened in many decades during the month of September. For the month so far, DC is averaging 1.6 degrees below-normal, Philly 1.3 degrees below-normal, and Central Park in New York City has a monthly average temperature of 0.8 degrees below-normal. Looking ahead to next week, an even colder air mass is destined to reach the central and eastern US as a deep upper-level trough forms overhead. This cold air outbreak for the central and eastern US will roughly coincide with the calendar transition from September to October with a couple of cold fronts ushering in a “step-down” to the colder-than-normal conditions. Once the colder-than-normal air mass becomes established, it looks like it’ll stick around right into the first full weekend of October. In terms of rainfall, a decent chance of rain will come on Monday and Tuesday as a couple of cold fronts push through the region at the leading edge of the colder-than-normal air mass.
