No luck for those hoping we'd seen the last of winter — the Baltimore region could get as much as 4 inches of snow by St. Patrick's Day.

A mix of rain and snow is expected to begin falling around 7 p.m. Sunday, changing to all snow by mid-evening and continuing through early afternoon, according to the National Weather Service. The heaviest snow is forecast to fall after midnight through early Monday morning.

The weather service has backed off a little in how much snow the metro area could see, downgrading its forecast from a winter storm watch packing up to five inches of white stuff to a winter weather advisory instead. The updated forecast predicted 2 to 4 inches of snow, with the lighter accumulations expected to the north of the city.

Meteorologist Amy Bettwy said the forecast was adjusted because the heavier bands of precipitation appeared to be tracking a little further south of Baltimore than earlier.

"There is still some uncertainty," she noted, so the forecast could change again as the storm nears.

Temperatures are expected to fall into the lower 30s by mid-evening, then drop into the mid-20s overnight. The high temperature on Monday should be in the lower 30s, the weather service said.

Winds will be around 10 miles per hour, with gusts up to 20 miles per hour, the service said.

Even with a little less snow, travel could still be hazardous, the weather service cautioned. Roads could be covered by snow and slippery, with visibility limited, Sunday night through the Monday morning commute.

The snowy winter has left department stores and local governments scrambling to restock their salt supplies. Public spending on salt and other snow supplies has climbed significantly from last year, The Sun reported earlier this month.
