Crisp, autumnlike nights, will blanket much of the eastern two-thirds of the country early this week while sunshine compliments pleasant afternoons. The sweeping area of high pressure bringing the change is a big sign that fall is just around the corner.
The refreshing change in air will settle into the country in wake of major cold front that sparked widespread severe weather from the Midwest to the Northeast Friday into Saturday. The two-day severe weather event ended late Saturday night with 462 reports of wind damage, 31 reports of hail larger than a quarter, and two tornadoes.
Twitter lit up late Saturday morning with countless photos of the tornadoes when they hit the New York City metro area.

Expert Senior Meteorologist Alex Sosnowski began talking about the cooldown last week. The cooldown and tranquility will make headlines this week, the severe weather that rattled the country Friday and Saturday reminds us why autumn has a different meaning for meteorologists.
The cooldown will put a dent into the summer heat that is in running for one of the hottest on record. Later this week, temperatures will gradually rebound to more seasonable levels.
Low pressure developing in the Tasman Sea will lead to strong wind, rain and pounding surf along the eastern Australia coast.

A storm system responsible for severe weather across the Plains over the past week, as well as the snow across the Rockies will advance eastward.
