Dangerous cold sets in; potential for another weekend winter storm brewing

A prolonged stretch of dangerous cold weather in the forecast for the Eastern Shore. Residents are urged to take precautions as temperatures and wind chills drop well below normal.

The National Weather Service in Wakefield has issued a Cold Weather Advisory in effect through Tuesday morning. Forecast conditions call for bitter cold air combined with gusty winds, producing wind chill values near zero and, at times, below zero across much of the region. More advisories are likely as Wednesday and Thursday are expected to be colder.

Along the Eastern Shore, wind chills are expected to range from zero to 10 degrees above zero overnight, while colder values as low as five below zero are anticipated farther inland. Meteorologists warn that exposure to these conditions could lead to frostbite or hypothermia if proper precautions are not taken.

Residents are encouraged to limit time outdoors, dress in layers, and ensure pets and livestock have warm, dry shelter, adequate food, and unfrozen water supplies.

The cold is being accompanied by increasing northwest winds, which have prompted additional marine advisories. A Gale Warning is in effect for the Chesapeake Bay and coastal waters north of the North Carolina border, including waters off the Eastern Shore. Forecasters expect sustained winds of 25 to 30 knots with gusts up to 35 knots, creating hazardous conditions for mariners. Seas are forecast to range from four to seven feet, with occasional waves approaching 10 feet offshore.

A Freezing Spray Advisory is also in effect through Tuesday morning for the bayside and seaside coastal waters. Light to moderate icing may accumulate on vessels, potentially damaging equipment, creating slippery decks, and reducing vessel stability. Additional freezing spray conditions are possible later this week as cold air remains entrenched across the region.

Looking ahead, the National Weather Service says temperatures are likely to remain well below normal for at least the next 10 days. Highs may struggle to rise above freezing, particularly across Maryland and northern Accomack County, with overnight lows staying well below freezing.

Forecasters are also monitoring the potential for another winter weather system this weekend as a developing area of low pressure moves offshore. There is still significant uncertainty regarding the strength and track of that system, and it is too early to determine whether it will have any impact on the Eastern Shore.
