Baltimore citizens are bracing for a significant wintery onslaught today, as the National Weather Service (NWS) Baltimore MD/Washington DC forecasts heavy snow and challenging conditions. According to their latest Area Forecast Discussion, an intense low-pressure system is crossing the region, bringing a mix of snow and freezing drizzle, particularly along the I-66 corridor and parts of central Virginia.
Commuters faced significant challenges this morning as "widespread snow showers" intensified, escalating snowfall rates up to 1.5 inches per hour in certain areas. According to the National Weather Service report, the latest storm system is expected to deposit 6 to 10 inches of snow across most parts of the forecast area, with pockets potentially witnessing over a foot north of I-64. "Reasonable worst case amounts of over a foot is possible for most areas north of the I-64 corridor." Despite the treacherous conditions, the accumulation won't halt anytime soon, as additional snow and freezing drizzle are forecast for different regions throughout the afternoon.
Sub-normal temperatures are here to stay, with the mercury set to drop into the teens, ensuring a solid refreezing overnight. The mountains could see impressive snow ratios thanks to the cold airmass, leading the NWS to issue a Slight Winter Storm threat for the Allegheny Front. The wintry grip tightens with a forecast of blustery winds and wind chills plummeting into potentially dangerous territories, requiring close monitoring and possibly Cold Weather headlines for the higher elevations.
Looking ahead, Baltimore's residents should bundle up as high temperatures will struggle to crest the 30-degree mark, while Thursday promises gusty northwest winds that could intensify the chill. Gusty NW winds will likely result in wind chills around 10 degrees colder, warns the NWS report. The forecast also hints at another potential winter weather event affecting the weekend. Although its track is highly uncertain, it might witness more snow if the low tracks are far enough north.
Maritime operations aren't spared either, with the NWS predicting that wintry weather will continue to impact the waters for much of the day today, necessitating a Gale Warning for the lower Tidal Potomac River and lower Chesapeake Bay areas. Pleasure craft and shipping should expect gusty conditions to last through Friday, with the potential for the intense conditions to exacerbate as we head into the weekend.
