With rain, then snow, expected to move into the region starting around rush hour Monday, the Maryland State Highway Administration said it’s already started pre-treating most of the major roads.
“It all depends on when the timing is,” said Charlie Gischlar, a spokesman for the SHA. “Storms are tricky, and there’s no permanent clock on them.”

Gischlar said right now, the rain doesn’t appear as if it will be heavy enough to wash away the salt that crews are putting on the roads.

Pavement temperature also makes a difference in road conditions during a storm—in February, the sun is slightly higher in the sky than it is in January, so that heats up the pavement more, Gischlar said. Air temperature is also key.
He reminded drivers to watch out for salt trucks and don’t try to pass them.
This latest round of winter weather comes two weeks after a blizzard dumped nearly 30 inches of snow on the Baltimore-Washington area.
While this storm isn’t supposed to dump anywhere close to that, Gischlar said the two back-to-back Snowmageddon blizzards of 2010 are still fresh in his memory.
“Those were also in February,” he said.
