12:45 PM | ****Nationwide cold pattern follows weekend exit of tropical storm…snow threat for the interior, higher elevation Mid-Atlantic/Northeast US…signs of longer-term cold pattern****

November 14, 2022Paul Dorian

At the same time Tropical Storm Nicole was pounding Florida on Friday with rain and wind, a blizzard was raging in the Northern Plains where two feet of snow piled up in such places as Bismarck, North Dakota. That late week cold air mass situated in the Northern Plains subsequently made its way into the northeastern US following the departure of Nicole to the open waters of the Atlantic Ocean. The exit of Nicole helped to bring about a change to the overall upper air wind pattern across North America. In fact, not only has the eastern US chilled down during the past 24 hours, virtually the entire nation is now featuring colder-than-normal temperatures and will likely do so right through the weekend. By the end of the week, many low temperature records will have been broken; especially, across the center part of the nation and every state in the Lower 48 can experience below-freezing temperatures.

In terms of snow potential, a coastal low will intensify by tomorrow night just off the Mid-Atlantic coastline resulting in a cold, soaking rain in the immediate I-95 corridor and to coastal sections, but the first accumulating snowfall of the season is likely in many of the interior, higher elevation locations across the northeastern states. The chill may ease up for awhile later next week, but there are signs for a resumption of the cold pattern going into late November and December.

Nicole climbed to category 1 hurricane status late yesterday and came ashore in the overnight hours near Vero Beach in east-central Florida. After landfall, Nicole has weakened slightly back to tropical storm status and will become increasingly influenced by a deep upper-level trough over the north-central states that is contributing to blizzard-like conditions in the Upper Midwest/Northern Plains. The remains of Nicole will ride up along the spine of the Appalachian Mountains over the next 24-48 hours resulting in a significant rain and wind event all the way from Florida-to-Maine. On the east side of the expected storm track, severe weather will be a possibility including the threat of isolated tornadoes. The passage of the tropical storm will be part of an overall significant temperature pattern change in the central and eastern US that will bring much colder weather conditions for the remainder of November.

Tropical Storm Nicole is headed towards east-central Florida for a likely landfall early Thursday morning. Some intensification is likely during the next 24-36 hours before landfall which could result in Nicole reaching category 1 or even 2 hurricane status before making landfall. After landfall, Nicole will be increasingly influenced by a deep upper-level trough over the central states and it’ll turn to the north and northeast resulting in a major rain event all along the east coast from Florida-to-Maine. In addition to the rain, severe weather will be a threat in the coastal plain from the Carolinas to the Northeast US which will be on the right side of the storm track…prime location for tornadic activity. The passage of the tropical system will be part of an overall significant temperature pattern change in the eastern US that will bring much colder weather conditions beginning this weekend and likely lasting through the remainder of November.

9:00 AM | ***Tropical Storm Nicole to reach Florida later in the week…possibly reaches hurricane status…moisture to ride up along east coast…part of transition to much colder pattern***

The tropical scene is still active and kicking in the Atlantic Basin and an area of disturbed weather in recent days has organized into Tropical Storm Nicole over the southwestern Atlantic Ocean. This system is likely to reach Florida later this week and there is a chance that it reaches category 1 hurricane status before making landfall. The moisture associated with Nicole is likely to then ride up along the eastern seaboard at week’s end. The passage of the tropical system will be part of an overall significant temperature pattern change across the nation that will bring much colder weather conditions to the central and eastern US.
