A powerful cold front is barrelling towards the east coast and it will be an important event in the typical autumnal transitional process of "stepping down" in temperatures from summer-to-winter. The month of September ended on Tuesday with high temperatures flirting near the 80 degree mark along the I-95 corridor and last weekend featured temperatures in the low-to-mid 80's - it'll be quite a challenge to see those kinds of high temperatures for quite awhile behind this front.
The upcoming frontal system will be mainly a "midnight-to-noon" event from late tomorrow night into mid-day Saturday with the threat for some heavy downpours and a possible thunderstorm. Slow clearing will hold off until later Saturday and it’ll occur from southwest-to-northeast in the Mid-Atlantic region (i.e., DC clears out well before NYC) as much cooler air pours into the area. Sunday will feature temperatures way below normal for early October and the cool weather pattern will continue on Monday and Tuesday although it won't be as chilly as on Sunday.
