Baltimore residents are prepping for a notable shift in weather patterns today. Forecasters at the National Weather Service in Baltimore, MD/Washington, DC, highlight a dance of atmospheric conditions set to roll across the region. According to the agency's latest update, a warm front is on the move today, pushing north and giving way to a cold front as it swings in from the Ohio River Valley tonight—a classic one-two punch of winter weather.
The forecast informs us to brace for a marked temperature drop into tonight, with the mercury slated to tumble into the 30s over the mountains and hover around the 40s to 50s elsewhere. But it's not just the cold snap to watch out for. The National Weather Service warns of a "formidable cold frontal rain band" due to roll in, accompanied by the potential for a few rumbles of thunder. And for those looking skyward, don't expect to see much lightning; the agency notes that while there's some instability, the spine of action is rooted above the surface. More concerning, perhaps, is the possibility of strong wind gusts and, while less likely, even a brief tornado in areas with the highest surface-based instability.
Looking ahead to Monday, a brief interlude of high pressure is expected to usher in some sunnier skies and milder temperatures. However, this calm is merely the quiet before another storm system approaches from the Ohio River Valley, underlining the short-lived nature of any respite from the season's volatility. Those aiming for outdoor activities should monitor the shifting conditions and adjust plans accordingly.
The agency's discussion also points toward a weather pattern from Tuesday to Saturday. Folks in the Mid-Atlantic can anticipate various cycles of cold cyclonic flow and spillover precipitation, primarily affecting those west of I-81, with the potential for mountain snow. The forecast signals a temperature tumble come Thursday, with highs struggling to escape the low/mid-30s. It notes a persistent longwave trough over eastern North America, potentially shaping the first weekend of 2025 into quite a chilly experience.
Aviators and mariners should exercise equal caution. Aviation conditions fluctuate between IFR and LIFR as visibility and ceiling heights fluctuate, with the potential for gale-force gusts on the waterways. Baltimore's National Weather Service office has issued dense fog advisories and Wind Advisories to account for these conditions, underscoring the need for heightened awareness and preparedness.
