Maryland greets the morning under a hard Arctic edge as wind whistles through bare trees and frozen pavement gleams under streetlights. The cold bites fast, and it is not letting go easily.

A Cold Weather Advisory remains in effect across the Baltimore–Washington region through late morning, with another advisory beginning tonight and lasting into Friday. According to the National Weather Service, wind chills may drop as low as 9 degrees below zero, creating dangerous exposure conditions in minutes.

Early today, Washington sits near 19 degrees, though strong northwest winds push wind chills closer to single digits. Baltimore and surrounding suburbs feel similar cold. Sidewalks may appear dry, but flash freezing is a real concern where melted snow refreezes. Drivers along I-95, I-495, and the BW Parkway should expect slick spots, especially on bridges and ramps.

Sunshine helps little today. Afternoon highs stall in the low 20s, and winds remain brisk. Tonight turns colder again as skies stay mostly clear. Wind chills fall sharply by early morning, setting up another bitter start to the day.

Friday stays cold but calmer, with highs near the low 20s. Attention then shifts to the weekend. A developing storm system brings a chance for snow late Saturday into Sunday. While exact totals remain uncertain, even light snow could snarl travel on untreated roads and sidewalks.

Sunday looks unsettled and blustery, with snow possible and gusty winds reducing visibility at times. Plan extra travel time and expect changing conditions by afternoon. Cold air lingers into early next week before gradual improvement.

Residents should dress in layers, limit outdoor exposure, and bring pets indoors. Check on neighbors who may need assistance and ensure space heaters are used safely.
