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.

Couldn't Be Worse...or could it?

Recent summers have been torrid in the Boston area. This summer, it was not so much the heat as it was humidity. The two previous, both! Along with the oppressiveness, a lack of rain, especially this summer. Few thunderstorms, and only one that could be described as strong. I noted very little lightning over the ocean in the course of this summer. To cap it off, smoke from western wild fires. I swear it was a factor in my being able to get close-up photos of an immature myrtle warbler. That bird looked infirm, at times, or at least lethargic. I just can't commit to a cold, snowy winter given what has preceded the last several years. Humanity - pejorative to climate change!

Couldn't be better

I'm a fan of warm weather, so I enjoy record warm temperatures for Most of the year. I prefer above average but not record setting during the summer. I enjoy Record setting temps from October-May. I also live in Southern New England, and I hate snow. (BTW Coastal Connecticut is where I'm at.) I hope the winter of 2020-2021 is 50s-60s for most of the days. OBV there's going to be cool times but as an average I hope it's in the 50s-60s. Would love to see 70s!

Brutal summer, IMO

I’ve Iived here my whole life and absolutely hate mid-Atlantic summers. Fall can’t get here soon enough. And I’m so much hoping for a snowy winter, but doubt it. It seems like this region becomes more and more like a southern state each year that passes. Long brutal summers and mild winters. I’d love to live in the far northeast.

Predicted forcast

Pretty much off the mark for July August.As far as the predicted 2020-2021 winter forecast goes, any good yankee knows if you have a particularly hot dry summer you will have a colder and snowier winter. Lets see who's closer.

Better Not Be a 2020 Winter. A Dud.

The winter of 2020 was trash, no snow. Some cold. Not really. I really hope the winter of 2021 brings snowstorms that give 2-3Ft of snow at a time. Especially to make up after last years dud of a winter.
