As Long Islanders mop up from superstorm Sandy, meteorologists have their eyes on models that indicate the potential for another storm -- a more typical nor'easter -- that could move along the Atlantic Coast next Wednesday or Thursday.

"There's still a lot of uncertainty," said Joey Picca, meteorologist with the National Weather Service in Upton.

The storm could bring moderate to heavy rainfall, northeasterly winds and gusts, he said.

Still, if a storm does develop, Picca said it's not expected to be "anything near the strength" of Sandy.

As time progresses, meteorologists will get a better fix as to whether a low-pressure system actually does develop in the Southeast, said Dan Hofmann, also a meteorologist in Upton. If such a system is to develop, it's too soon to tell where it might track and its intensity, as "it could be weaker and head farther out to sea," he said.

"Global numerical models suggest no rest for the weary across the United States," with conditions allowing for "the possibility of another slow-moving cyclone along the mid-Atlantic and Northeast coasts," said a preliminary extended forecast discussion issued Friday morning by the National Weather Center.

"Any system that produces significant wind and precipitation in the mid-Atlantic and Northeast is of note in light of the continued recovery from Sandy and its post-tropical transformation," the center said.
