In a look ahead, it is not unusual this time of year for the passage of a tropical system to result in a major temperature pattern change across the nation and indeed it appears as though the central and eastern states will turn much colder beginning later this weekend. Cold air masses that have been bottled up across the western parts of Canada and the US in recent days, but soon will be able to flood into the central and eastern states as the overall wind flow aloft will change following the exit of Tropical Storm Nicole to the Atlantic Ocean. Much colder conditions are likely here in the Mid-Atlantic region by Sunday and Monday of next week with a possible freeze on Sunday night and the noticeably colder weather pattern looks like it will continue as we progress right through the second half of November.
