The National Weather Service Baltimore MD/Washington DC has announced a drastic drop in temperatures across the region, setting the stage for what may be the coldest night in several years. With the approach of an Arctic high-pressure system, residents should brace for record-breaking lows that could surpass longstanding winter records.
Brutally cold conditions are expected to persist through this weekend, with wind chill temperatures plummeting to hazardous levels. Specifically, the areas northwest of I-95 may experience wind chills ranging from a bone-chilling -20F to -25F. Near -35F wind chills are forecast for western Pendleton County, according to the National Weather Service. These conditions have prompted the issue of Extreme Cold Warnings and Cold Weather Advisories for the entire region for tonight into Tuesday morning.
Traveling upwards to the Alleghenies, the threat of mountain snow continues to loom through mid-week. Although the snowfall is expected to be light, accumulations of 1-2 inches can still pose difficulties. The current Winter Storm Warning, as outlined by the National Weather Service, remains in effect until 10 AM today, but there is potential for an early lift depending on radar trends.
For aviators, conditions over the next few days are looking VFR (Visual Flight Rules) suitable through Tuesday. Despite this, the winds present another story, with gusts picking up strength today to around 25 to 30 knots, potentially impacting flights, as per the forecast discussion. These brisk conditions are expected to continue throughout the week, complicating travel and transport across marine sectors as well.
Marine advisories have similarly been set in place due to the strengthening coastal low off the Delmarva coast. Gale conditions across much of Chesapeake Bay and the lower tidal Potomac River have warranted Gale Warnings for today into this evening, with freezing spray advisories also issued for all waters tonight. Vessels should exercise caution and adhere to these advisories to mitigate the risk of being caught off-guard by the harsh conditions.
Last but not least, the historic chill is also making its mark in the record books. Several temperature records for the region are expected to be tied or broken during this cold snap, with daily temperature records for Baltimore, Washington, and the surrounding areas dating back to the mid-1900s at stake, as outlined in The National Weather Service's climate data.
