Snow Squalls Possible, Wind Advisory In Effect In Harford County

HARFORD COUNTY, MD — Strong winds, chilling temperatures and possibly a snow squall are in the forecast for Harford County on Wednesday. Forecasters advise power outages are possible as well as dangerous driving conditions. As evening arrives, a wind chill advisory will be in place.

As an arctic front moves across the mid-Atlantic, the National Weather Service reports that strong winds will arrive.

A wind advisory is in effect from 9 a.m. to 6 p.m. on Wednesday, Jan. 30, for much of central Maryland, including Harford County. It calls for 25 to 35 mph winds with gusts up to 50 mph, that may bring down trees and power lines, resulting in power outages. The National Weather Service issues a wind advisory when winds of 45 to 55 mph are expected that can make driving difficult.

A snow squall is also possible Wednesday in central Maryland, bringing rapidly changing weather and dangerous road conditions. Brief periods of heavy snow and 50 mph wind gusts could occur, and 1 inch of snow may quickly accumulate, weather officials said.

At 11:13 a.m., officials said that a dangerous snow squall was moving east at 20 mph through west central Maryland, the easternmost part of West Virginia and northwestern Virginia.

"Snow showers or snow squalls could enhance gusty winds and briefly lower visibility, resulting in very hazardous driving conditions," the National Weather Service advised in a special weather statement after 10 a.m. on Wednesday. The statement, which cautioned drivers ahead of potential whiteout conditions from heavy wind and blowing snow, applies to Anne Arundel, Baltimore, Carroll, Cecil, Frederick, Harford, Howard and Montgomery counties as well as Baltimore City, DC and parts of Virginia.

Drivers in these areas should slow down and turn on headlights.

"Motorists are urged to use caution if encountering any of these squalls from late this morning through the afternoon," the National Weather Service advised. "A narrow but solid line of heavy snow moving through central Pennsylvania this morning is forecast to move into eastern Pennsylvania and the far northern portions of the Delmarva around noon, then into New Jersey during the afternoon hours. This line of snow represents the leading edge of arctic air that will invade the area later today through Friday."

Here is a snow squall reported Wednesday morning in State College, Pennsylvania:

Continued forecasters: "Snow squalls associated with this line have a history of producing heavy and blowing snow for periods of 10 to 15 minutes, resulting in a rapid reduction of visibility, along with wind gusts in the range of 30 to 50 mph and a quick coating to around an inch of snow accumulation."

Baltimore, Frederick, Carroll, Harford, Howard, Montgomery and Washington counties are also under a wind chill advisory from 6 p.m. Wednesday to noon on Thursday.

The advisory calls for wind chills of 10 to 20 degrees below zero in portions of northern Maryland, northwest Virginia and the eastern panhandle of West Virginia.

Frostbite may develop in as little as 30 minutes, according to the National Weather Service.

To protect themselves, people going outside should dress in layers, wear a hat and put on gloves.
