Hello! I was wondering what

Hello! I was wondering what the weather will be like for this winter, (in terms of snow!)
Oh, and I want the weather in Central NJ, (Trenton Area)

Winter weather

The Editors's picture

Hi, Shaan, Here are our winter predictions by U.S. region. Our long-range predictions are based on weather regions (versus state/city). For more detail, we hope you’ll pick up a copy of our annual book—The 2021 Old Farmer’s Almanac!.Stay cozy!

Snow 12/2020

The snow we got in South Jersey, Cumberland County, was a rollercoaster. First, excitement for family fun to ride in snow, then rain to take it away in about an hour. Meanwhile 50 mins North, Cherry Hill, I went and made money shoveling the next morning. Doesn't seem fair.. Missing my winter trips living in Maine for the winters, and the snow we used to enjoy here so much years ago. Please give us some snow...

More hurricanes/storms in summer??

Not happy to read about a hurricane in early August. This area doesn't usually see storms like that this early. I know this past summer we had Isaias (sp?) which hit here (LI, New York) as a moderate tropical storm, but a hurricane?? I hope this prediction doesn't end up coming true. For what it's worth, I remember the tropical storm threat predicted for this area back in mid-October and it never materialized. Fingers crossed this one won't either.

Weather Blah

2020 summer was terribly hot and humid with 3-4 tropical storms that came up the coast. This second Nor'easter that just blew through dumped 6-8 inches of snow and sleet in SE PA. I've had enough water in all forms for quite a while.


Can't wait for it to snow. Last year was disappointing because we didn't get any sticky snow! Fingers crossed for this season. We need snow to kind of fix 2020 for us. I guess quarantine was a result of asking for snow days too many times!

Hoping for a-lot of Snow

As a snow lover that lives in Maryland (near Baltimore), the last few seasons have been disappointing to say the least. I sincerely hope for a very snowy winter this year. Perhaps is should move to Toronto once I graduate!


Time to get the tires together in preparation for that snow and get the hot chocolate brewing.

Hoping For Much Snow, says Dec-Jan/Mar 2021

Seems like we never get a snowy winter especially when I'm prepared for it or at least prepared for the fun aspect of it. I remember all the quads and sleds out in the past and now that we have them and a place to ride them there will most likely be no snow as it says... It's ashame that our weather has changed drastically this goes to show you things are not going too well for our planet...

Winter 2020-2021

I live in Richmond, Virginia and I really hope that this winter will be a snowy winter. Last Winter, we only had one snow day which is certainly abnormal for Richmond. We usually have several.
