Snow Returns To MD: Timing, How Much Accumulation To Expect

Rain falling across Maryland could turn to snow on Thursday as colder air moves in, bringing gusty winds and dramatically cooler temperatures to the Baltimore region through the day.

A hazardous weather outlook is in effect for the Maryland portion of the Chesapeake Bay, the tidal Potomac River, and the I-95 corridor through central Maryland as a massive cold front moves through the state.

According to the National Weather Service, rain falling in Maryland could precede a brief period of snow on Thursday. If any accumulation occurs, it will likely be on grassy surfaces.

In Southern Maryland, snow may be heavier and could cause some slush on roads.

As for timing, The Washington Post's Capital Weather Gang wrote that rain on Thursday morning may mix with or turn to snow before ending in the early afternoon.

"With temperatures above freezing, there’s not much concern about iciness," Capital Weather Gang forecasters wrote.

After reaching more than 80 degrees on Wednesday, cold temperatures will make a chilly comeback through Thursday. Highs are expected to be in the 40s, but could slip into the 30s.

Strong, blustery winds are also expected on Thursday, averaging around 15 mph with gusts approaching 30 mph.

Winds prompted National Weather Service forecasters to issue several alerts for Maryland waters, including a small craft advisory for the tidal Potomac River from Key Bridge to Smith Point, and the Chesapeake Bay and adjoining estuaries north of Smith Point, Virginia.

"A brief period of gusts near gale force is possible this morning," forecasters wrote. "Inexperienced mariners, especially those operating smaller vessels, should avoid navigating in hazardous conditions."

Looking ahead, the Baltimore region should see temperatures in the mid- to upper 50s on Saturday and then 50s to low 60s on Sunday.

Temperatures will fall again early next week, ushering in a return to more winter-like conditions.
