Baltimore, MD – After a stretch of dry fall weather, Maryland residents should prepare for a midweek soaking as a strong storm system from the Tennessee Valley moves in late Wednesday, bringing steady rain, gusty winds, and possible localized flooding. Forecasters say the heaviest rainfall will occur overnight Wednesday into early Thursday, followed by improving conditions heading into the Halloween weekend.
The Weather Setup: Systems Collide Midweek
A high-pressure system over Canada will keep skies mostly dry through Tuesday night, though some clouds are expected to drift across the region. Meanwhile, a weak low near the Carolinas continues moving offshore as a developing storm system in the Tennessee Valley gears up to impact the Mid-Atlantic.
Meteorologists expect that system to become the main driver of Maryland’s weather midweek, bringing widespread rain to central Maryland, including Baltimore and surrounding suburbs.
Maryland Wednesday & Thursday: Rain, Wind, and Mild Temperatures
Clouds will increase through the day Wednesday, with rain chances rising by afternoon. By Wednesday evening, steady rainfall will overspread most of central Maryland. The heaviest rain is expected overnight into early Thursday, with 1–2 inches possible in many areas.
“Localized flooding in poor drainage spots is possible, especially where heavier bands set up,” forecasters warned.
Temperatures will remain cool in the 50s on Wednesday, then climb into the 60s Thursday as warmer air moves in ahead of the approaching front.
While severe weather is unlikely, a few claps of thunder could accompany the heaviest rain bands. By Thursday afternoon, winds will shift to the west, and rain will gradually taper off. Clearing skies are expected Thursday evening, with cooler and breezy conditions returning overnight.
Halloween Forecast for Baltimore (Friday): Dry, Cool, and Breezy
Trick-or-treaters can breathe a sigh of relief — Halloween looks dry across Maryland. Once Thursday’s rain clears, high pressure builds in, bringing a crisp and comfortable day for outdoor festivities.
Daytime highs will reach around 58–60°F under partly to mostly sunny skies, but temperatures will drop quickly after sunset, dipping into the upper 40s by early evening and the low 40s overnight.
“It’s shaping up to be classic fall weather — cool, dry, and perfect for Halloween plans,” local meteorologists said.
Light to moderate northwest breezes may persist early in the day, easing as the evening progresses.
Weekend Outlook: Breezy Saturday, Mostly Dry Sunday
The breezy pattern continues into Saturday morning, with gusts of 25–30 mph possible before calming later in the day. Sunshine will dominate, and afternoon highs will hover near 60°F — ideal for outdoor activities.
A weak system passing to the south late Sunday could bring a few spotty showers, but most of the weekend should remain dry across Baltimore and central Maryland. Temperatures will stay seasonable, with highs in the 50s to low 60s and lows in the 40s.
Early Next Week: More Rain and Cooler Air to Follow
By Monday, another stronger low-pressure system moving through the Great Lakes could send another round of rain across Maryland. Behind it, expect a cooler, drier pattern to return Tuesday, with temperatures dropping back into the 50s and nighttime lows in the 40s.
This next system will help reinforce the region’s typical late-October chill, setting up a stretch of brisk, sunny days as the new month begins.
Conclusion
After several quiet days, wet and windy weather will make a short return midweek before clearing in time for Halloween celebrations. Residents are advised to watch for localized flooding Wednesday night and plan for a cooler, breezy end to the week — perfect for enjoying Maryland’s colorful fall season.
