Weekend Coastal Storm Still Tough to Predict

Keep an eye on the forecast as Sunday approaches

A coastal storm could reach D.C., but it’s a tricky system to predict.

Any time a storm comes across the southern part of the nation, it has a chance to pick up a lot of moisture from the Gulf of Mexico, Storm4 Chief Meteorologist Doug Kammerer said. Then, if it turns the corner and heads up the East Coast, it could become a big storm for much of the mid-Atlantic and Northeast with snow toward New York and possibly in the D.C. area.

If it doesn’t turn that corner, which Kammerer was leaning toward Wednesday evening, there would be little precipitation, possibly starting with a little bit of rain that might turn to a little bit of snow around D.C.

Several computer models help predict the weather, but two that Storm4 considers very seriously are predicting very different futures for this storm, according to Kammerer. One is predicting rain and a huge storm. The other is predicting a weak storm with little if any precipitation.

During La Nina years, it’s difficult for big coastal storms to develop, Kammerer said. He expects some northward movement of this storm but not “a monster moving up the coast.”

As of Wednesday evening, Kammerer predicts some light rain and snow along the I-95 corridor through Washington and Baltimore but no further north.

But keep following the forecast. Predictions will change by Sunday morning.
