Baltimore residents should brace for an extended period of cold as below-normal temperatures are expected to continue throughout the week, according to the National Weather Service Baltimore MD/Washington DC. In a recent forecast discussion, the agency detailed how the negative Arctic Oscillation/North Atlantic Oscillation (AO/NAO) pattern is to blame for the chill that's taken hold of the Mid-Atlantic. While the weekend coastal low is moving on, the area won't see much respite from the cold with wind chill values hanging in the single digits and gusts reaching up to 40 mph. Prepared for the wind, cold weather advisories are in effect across the region.
Adding to the winter woes, a clipper-type low could bring light snow to the area by Tuesday night. The region is expected to undergo a relative 'warmup' with temperatures possibly rising above freezing on Monday and potentially hitting the low 40s by Tuesday, according to the National Weather Service. However, this break from the deep freeze is short-lived as the quick-moving clipper brings back colder temperatures soon after.
Also on the horizon, towards the week's end, is another potential bout with Old Man Winter. The area could see upslope snow and an ensuing cold outbreak once again. Forecast ensembles show a high probability of accumulating snow along and west of the Allegheny Front, while those farther east may experience gusty winds and snow showers. The National Weather Service cautions that blustery conditions and another round of frigid temperatures are quite possible in the wake of this system heading into next weekend.
Air travelers will also feel the impact of the weather. VFR conditions are expected for now, but vigorous northwesterly winds could gust up to 35 knots today. While the winds will gradually subside into Monday, the approach of the clipper system late Tuesday could lead to sub-VFR conditions in light snow. The National Weather Service warns boaters of strong Chesapeake Bay winds and subsequent freezing spray that could lead to low water conditions and possible property damage. A series of marine advisories and warnings is in place, reflecting the combination of sustained high winds, waves, and subzero temperatures.
For those living near waterways, strong northerly and northwesterly winds have led to blowout tide conditions today. The presence of ice buildup raises concerns about ice blocks being pushed away from the shore, potentially causing property damage. Though tide levels are anticipated to rebound early next week, the National Weather Service advises caution over the potential for low water issues to persist into Monday.
