Baltimore is bracing for a cold snap as strong Canadian high pressure is slated to dominate weather conditions through Monday, ensuring a dry but chilly start to the week. According to the latest area forecast from the National Weather Service Baltimore MD/Washington DC, the day's mercury isn't expected to climb much above the freezing point, with highs reaching the 20s to lower 30s National Weather Service.
Tonight, the clear skies and calm winds allow temperatures to plummet sharply, edging down to the lower teens. Pockets along the MD/PA border and in the Alleghenies could even witness single-digit lows. A weak change comes Monday afternoon, though highs are only expected to hover around the 30s. "Very cold through the day as highs reach the 20s to lower 30s, with a lingering north wind gusting to around 15 mph at times," the National Weather Service states, indicating the need for residents to suitably bundle up before venturing outside.
Looking ahead to Tuesday, a clipper system passing by might bring some wintry mixes along the northern fringes of the region. On Tuesday morning, the decaying front could bring some wintry precipitation to parts of the Alleghenies and areas along/north of I-70. Model soundings indicate the potential for freezing rain/sleet and snow, though confidence is low now, the National Weather Service detailed. Such conditions could complicate the morning commute, speaking to the unpredictability that winter weather can often present.
The rest of the week appears more moderate, with high-pressure forecasting comparatively drier conditions on Wednesday and Thursday. Light rain showers are on the cards for Friday and Saturday as another system edges closer to the region. A slight chance of rain showers returning for Friday and Saturday as a low-pressure system and associated frontal boundaries approach from the Mississippi River Valley, the Weather Service advises, suggesting that Baltimore residents should be prepared to unpack their umbrellas once again.
As for the Chesapeake Bay, boaters can expect North winds to gust around 20 knots through this afternoon, with the National Weather Service issuing Small Craft Advisories for certain areas. However, these windy conditions will subside by evening, with no similar advisories anticipated through Tuesday night. Overall, it's a week of true winter weather, reminding us that the season's grip is firm—even as the calendar turns toward its end.
