Discussion              

Yesterday was very likely the warmest day that we’ll experience around here until next spring as a cold frontal passage has ushered in a noticeably cooler air mass for the next couple of days and a big-time pattern change to cold begins later this weekend. Before we get to the transition to a cold pattern, a major rain event is in the cards for the eastern seaboard from Florida to Maine as tropical moisture associated with Tropical Storm Nicole rides up along the coast. The rain is likely to begin here during the day on Friday and then intensify on Friday night before winding down early Saturday. By later Sunday night into early Monday, a widespread hard freeze will be possible with temperatures likely dropping to well below freezing levels.
