Snoopy, Charlie Brown and even the Grinch may have a lot to be thankful for this year.

It looks like winds on Thursday won’t be quite strong enough to ground the balloons at the Macy’s Thanksgiving Day Parade — although the margins are carving-knife-thin.

The forecast is for sustained winds of 12 to 25 mph and gusts of up to 35 mph. If sustained winds exceed 23 mph and gusts surpass 34 mph, none of this year’s 16 character balloons and nearly 30 legacy balloons will be allowed to soar over the 2.65-mile route along Central Park West, Sixth Avenue and West 34th Street.

“It’s going to be very close to that threshold, likely right below it,” said AccuWeather senior meteorologist Dave Dombek.

The parade, a tradition since 1924, will feature 1,500 dancers and cheerleaders, nearly 1,000 clowns, Broadway performers, including the casts from “Mean Girls” and “My Fair Lady,” and celebrities like John Legend, Kelly Clarkson and Diana Ross.

But they’ll be cold. The winds will make bone-numbing mid-20s temps feel even more brutal for what likely will be the coldest Turkey Day in the Big Apple in more than a century.

The forecast is on the cusp of the record set in 1901, when it was 19 degrees in Central Park. The last time the balloons were grounded due to heavy winds was in 1971.

At Wednesday night’s balloon-inflation ceremony near the Museum of Natural History, NYPD Commissioner James O’Neill said police would be monitoring the winds closely.

“We’ll just have to take down the balloons” if winds pass dangerous levels, he said, urging New Yorkers to “think positive.”

Thousands of people roamed around by the Upper West Side museum to catch a glimpse of a giant SpongeBob SquarePants, Ronald McDonald and Olaf from “Frozen,” as they were filled with air in preparation for the Thanksgiving festivities.
