Maryland greets the morning wrapped in sharp December cold. Clear skies stretch over Baltimore and the I-95 corridor, but the air stings. Temperatures sit near 24 degrees, cold enough for frost and lingering icy patches on untreated sidewalks.
Sunshine helps today, yet the chill remains stubborn. Highs climb only into the mid-30s, keeping winter coats essential for commuters and early errands. Roads stay dry for now, though refreezing remains possible in shaded areas.
A noticeable shift arrives midweek. Milder air builds Wednesday as clouds increase, pushing afternoon temperatures into the upper 40s. To be fair, this brief warmup may feel welcome, but it sets the stage for the next system.
Thursday, December 18th, brings the most impactful weather. Rain spreads in during the afternoon, becoming steady by evening. Temperatures peak near 53 degrees, leaving wet pavement across Baltimore, Washington, and surrounding suburbs. Plan extra time for travel, especially during the evening commute.
Conditions change again Thursday night. Colder air filters back in, dropping temperatures into the upper 40s, then toward freezing by early Friday. While snow is not expected, flash freezing becomes a concern where water lingers on roads, bridges, and ramps.
Friday turns cooler and quieter. A lingering chance of rain early gives way to clearing skies, with highs near 47 degrees. Overnight lows fall into the upper 20s, allowing slick spots to redevelop by Saturday morning.
The weekend trends calmer but seasonable. Saturday stays partly sunny with highs near 43 degrees. Sunday turns milder, reaching the low 50s, before cooling again early next week.
Winter patterns are clearly active across the Mid-Atlantic. Timing will matter as temperatures swing quickly.
