REHOBOTH BEACH — Word from up north is that the groundhog has predicted six more weeks of winter.

But keep in mind, he’s only right 40% of the time.

For Delaware, we do have at least two more days of winter ahead.

As the name of this weekend’s big event suggests, it is time for a polar plunge.

Temperatures will plummet Friday, starting around 40 in the morning but dropping to the 20s in the late afternoon. The temperature may not get out of the 20s all day Saturday, forecasters said.

But for Sunday’s Lewes Polar Bear Plunge to benefit Special Olympics Delaware, the air temperature is anticipated to be around 49 and the water temperature about 39 degrees when the “bears” dash into the chilly Atlantic Ocean.

Last year’s plunge, with more than 3,000 bears participating, was on a 37-degree day with 32-degree ocean water temperatures.

In western Pennsylvania Thursday morning, Punxsutawney Phil saw his shadow when he was roused from his tree stump in the annual Groundhog Day celebration.

According to folklore, if he sees his shadow, there will be six more weeks of winter. If he doesn’t, spring comes early.

Delaware does not have a rodent that predicts the weather.

So, we’ll rely on the National Weather Service, for the immediate future. Temperatures will be in the 50s all of next week.

The National Oceanic and Atmospheric Administration compared Punxsutawney Phil’s forecast to the national weather the last 10 years and found “on average, Phil has gotten it right 40% of the time.”
