The National Weather Service has issued a winter weather advisory that will be in effect from 9 a.m. to 6 p.m. on Tuesday.

Edgar Cano of Evanston’s Public Works Agency says he’s looking for wet snow from 10 a.m. to 4 p.m., with the heaviest bursts occurring between 10:30 a.m. and 1 p.m.

It should then taper off to light snow before switching to all rain due to rising temperatures.

The Weather Service says we could get up to three inches of snow on grassy surfaces from the storm and Cano says that on pavement it’s expected to be an inch to 1.25 inches of slush because of warm pavement temperatures.

“We only expect slush on pavement and no bonding to occur, so this should minimize or eliminate the need for salt,” Cano says.

Evanston may get more snow later in the week. Cano says, “We are also monitoring a system for Wednesday into Thursday and another one that may affect us on Saturday into Sunday.”
