Thanksgiving Storm Brings In Colder Air And Maybe A Little More Snow
November 24, 2024 – Sunday Night Report
If you have plans to travel this holiday week or have people coming to see you, then the weather may be a factor. Storms are pretty common during Thanksgiving week, but no two are the same. They are also NOT like the movie Planes, Trains, and Automobiles… thankfully. But any weather with rain, snow, or wind can have a big effect on road traffic or airline delays. My goal in this report is to give a broad view of the weather in the Eastern US for general travel ideas.
The pattern has flipped, and it is about to get reinforcements. The recent snow has come and gone already. The next couple of days will be mild, and we might hit the 60s again. That is just the calm before the storm.
As the weather becomes more active this week, a series of storms will arrive. The first will bring rain on Tuesday, then temperatures cool with a strong storm passing through on Thursday, followed by the coldest air of the season into the weekend.
Thanksgiving Thursday is the main event, and at this point, it looks like primarily a rainmaker for the Mid-Atlantic and big cities through New England. Farther inland, a snowstorm is more likely for western and central New York to the northern New England mountains.
Let’s take a look:
Jet Stream: Animation Monday Afternoon to Sunday
The week will start off warm and quiet. This is seen in the orange colors representing the Ridge up the Eastern US.
A series of colder air masses will push in this week, with the mother load of cold air settling in next weekend.
Snapshots
Thanksgiving Afternoon
I’ve annotated the Low Pressure that will be the storm moving across the Northeast. This will be followed by a noticeably colder air mass.
Sunday Afternoon
It looks like a mid-winter pattern. This will not have mid-winter cold yet, but definitely a hint of it. This is the air mass that may bring the 30s into northern Florida in the morning and a clipper and light snow into the Mid-Atlantic.
Storm Animation Part 1 of 2:
Tuesday Morning to Friday Morning
First, a line of rain on Tuesday. Then, the larger storm will make Thanksgiving Day soggy across the Eastern US. The colder air will be confined near the Great Lakes. This is expected to result in snow from Buffalo to Syracuse and up to Northern New England.
Snapshots
Tuesday Morning
Moderate to steady rain will expand from the Mid-Atlantic into New England. Showers will extend south through Atlanta and New Orleans.
Thanksgiving Morning
If you are doing a Turkey Trot run, it will be wet for much of the Eastern US. We can call it soggy from Central Pennsylvania through the Ohio Valley and southward towards Atlanta.
Snow may start the day from Cleveland to Scranton and Buffalo.
Thunderstorms may be strong on the southern edge.
Thanksgiving Afternoon
The heaviest rain will move away from Baltimore and through New York and Boston.
Strong to severe thunderstorms will need to be tracked from the Florida Panhandle to Eastern North Carolina.
Snowstorm: Moderate to heavy accumulation between Buffalo, Binghamton, Syracuse, and up to North New England.
Snow will be returning to the high mountains of Western Maryland to West Virginia.
WEEKEND
The storm will end for Friday shopping or travel.. setting up the colder winds.
Saturday Morning Temperatures
Much of the Mid-Atlantic and New England will start the day in the 20s. Farther west, near Chicago and the Northern Plains, the next push of colder air will be felt in the teens.
Looking southward: The 30s will make it into Georgia and perhaps northern Florida.
Orlando will be down into the 40s.
Storm Animation Part 2 of 2: Saturday Morning to Sunday Morning
With the exception of Lake Effect Snow, the rest of us will dry out as the cold air sets in. The cold pattern will be active, sending a fast-moving clipper-like system into the Mid-Atlantic Sunday morning with light snow or flurries.

Surface Weather Forecast
7 AM
This looks like a light system with flurries or light snow.
10 AM
Flurries or light snow.
This does validate the recent NOAA Temperature Outlooks. After this weekend, the cold air seems to hold into the start of December.

RESTATING MY MESSAGE ABOUT DYSLEXIA
I am aware there are some spelling and grammar typos and occasional other glitches. I take responsibility for my mistakes and even the computer glitches I may miss. I have made a few public statements over the years, but if you are new here, you may have missed it: I have dyslexia and found out during my second year at Cornell University. It didn’t stop me from getting my meteorology degree and being the first to get the AMS CBM in the Baltimore/Washington region.
One of my professors told me that I had made it that far without knowing and to not let it be a crutch going forward. That was Mark Wysocki, and he was absolutely correct! I do miss my mistakes in my own proofreading. The autocorrect spell check on my computer sometimes does an injustice to make it worse. I also can make mistakes in forecasting. No one is perfect at predicting the future. All of the maps and information are accurate. The ‘wordy’ stuff can get sticky.
There has been no editor who can check my work while writing and to have it ready to send out in a newsworthy timeline. Barbara Werner is a member of the web team that helps me maintain this site. She has taken it upon herself to edit typos when she is available. That could be AFTER you read this. I accept this and perhaps proves what you read is really from me… It’s part of my charm. #FITF
