Baltimore, MD – Chilly mornings and another potential round of frost are affecting portions of central Maryland as temperatures remain cold enough for frost to develop outside major cities through early Monday, Oct. 26. The National Weather Service is highlighting continued frost concerns near and west of Interstate 95, particularly in sheltered communities away from the Chesapeake Bay. Meanwhile, Baltimore is expected to experience a stretch of dry, relatively mild afternoons before temperatures briefly ease into the mid 60s Wednesday and rebound into the 70s later in the week.
According to the National Weather Service Baltimore/Washington office, a Hazardous Weather Outlook issued at 2:52 a.m. Sunday identifies frost as the primary near term weather concern across portions of central Maryland, northern Virginia and the District of Columbia region. The outlook references a Frost Advisory affecting most areas near and west of Interstate 95 until 9 a.m. Sunday, with additional frost possible late Sunday night into early Monday morning.
Frost Threat Continues Outside Major Cities The greatest concern involves locations away from the immediate Chesapeake Bay shoreline and outside major urban centers, where colder nighttime conditions can allow frost to develop on exposed vegetation. The National Weather Service specifically notes that frost remains possible through early Monday morning, even as daytime temperatures climb considerably higher.
Baltimore's official point forecast calls for a low near 45 degrees Sunday night, which is not especially favorable for widespread frost within the city. However, temperatures can vary across central Maryland, particularly in rural valleys and sheltered locations farther from the warming influence of urban development and tidal waterways. Residents in frost prone communities should monitor their local forecast rather than relying solely on Baltimore's temperature.
Gardeners with sensitive flowers, vegetables or container plants may want to take precautions before temperatures fall Sunday evening. Moving vulnerable potted plants indoors or covering exposed vegetation can help reduce potential damage. The supplied outlook does not indicate a widespread hard freeze across Baltimore or establish a new Frost Advisory extending through Monday morning.
Baltimore Temperatures Shift Through Wednesday While frost remains a concern in some surrounding communities, Baltimore's daytime forecast is considerably milder. Sunday brings sunshine and a high near 66 degrees, followed by mostly clear skies and a low around 45 degrees. Monday, Oct. 26, is expected to reach approximately 72 degrees, with sunny skies and northwest winds around 6 mph during the afternoon.
Tuesday remains sunny, with temperatures reaching approximately 68 degrees before dropping to 47 degrees Tuesday night. By Wednesday, Oct. 28, partly sunny skies accompany a high near 65 degrees, making it the coolest afternoon in the Monday through Friday forecast period.
The difference between Monday's 72 degree high and Wednesday's 65 degree high represents a gradual seven degree decline over two days rather than a sudden temperature collapse. Wednesday night should remain mostly cloudy, with temperatures falling to approximately 50 degrees.
For commuters traveling Interstate 95, Interstate 695 and Interstate 83, the local forecast does not identify significant rainfall, snow, ice or widespread hazardous travel conditions. However, drivers traveling through rural or low lying areas during colder early morning periods should remain aware of changing local temperatures.
Sunshine and Warmer Weather Return Before Halloween Thursday, Oct. 29, brings a noticeable improvement as mostly sunny skies return and temperatures climb to approximately 71 degrees. Thursday night remains mostly clear, with a low near 53 degrees.
Friday continues the warming trend, with sunshine and an afternoon high near 76 degrees. Saturday, Oct. 31, is expected to remain mostly sunny, with temperatures near 72 degrees, providing a favorable daytime outlook for Halloween activities across Baltimore and surrounding communities.
The forecast suggests that the immediate frost concern will give way to several days of generally comfortable autumn weather. Although colder mornings remain possible as November approaches, the supplied outlook does not indicate a significant winter storm or widespread freezing precipitation event for the Baltimore area.
Have you already brought sensitive plants indoors, or are you looking forward to Baltimore's return to the 70s before Halloween?
