Snow is predicted this weekend, as temperatures fall from springtime levels, a National Weather Service meteorologist said Thursday.

“Today is the last warm day for quite a while,” Mike Rusnak said Thursday afternoon.

The high temperature on Saturday is predicted to be in the 40s, with lows in the 20s. The high Sunday is predicted to be in the 30s. Up to a half inch of snow is predicted for the Richmond and Norfolk metro areas.

Rusnak said a cold front is expected to drop the temperature on Friday. Snow projections have diminished during the past couple of days, but “any snow that does fall Saturday night will stick before temperatures rise above freezing Saturday afternoon.”

“It’s going to be a sharp line between where it snows and where it doesn’t,” he said.

A storm system moving up the East Coast on Monday will bring even colder air and drop temperatures even further. Temperatures for next week are expected to be “well below” normal.

“Normal for this time of year is highs in the mid-50s,” Rusnak said. “We’re looking at 10 degrees below that.”
