Baltimore, Maryland – A turn toward colder weather during the Jan 20–24 period is increasing concern for snow across Maryland, particularly if storm systems pass through while colder air is in place. While temperatures are not expected to be extreme, the shift toward below-normal readings raises the likelihood that precipitation could fall as snow rather than rain.
According to the National Weather Service Climate Prediction Center, Maryland carries a 50–60% probability of below-normal temperatures during the January 20–24 window. Precipitation probabilities remain above normal at 40–50%, a combination that supports snow potential, especially during overnight and early morning hours when colder air is most established.
In Baltimore and central Maryland, daytime temperatures may hover near seasonal levels but are expected to dip below normal at night, increasing the risk for accumulating snow if precipitation develops. Interior locations west of I-95, including Frederick, Carroll, and Howard counties, have a higher chance of seeing snow stick, while areas closer to the Chesapeake Bay may see more variable outcomes depending on storm timing and temperature profiles.
Major travel corridors such as I-95, I-83, I-70, and the Baltimore Beltway could become slick during snow periods, particularly during the morning commute. Cold pavement temperatures may allow snow or ice to linger on untreated roads, bridges, and overpasses even after precipitation tapers off.
Residents are encouraged to prepare ahead of the Jan 20–24 window by monitoring updated weather information, checking heating systems, and ensuring vehicles are winter-ready. While significant snow is not guaranteed, the evolving pattern supports the possibility of at least one impactful winter weather event.
This colder pattern is expected to persist through late week, and additional advisories or alerts may be issued as confidence in timing and impacts increases.
