Baltimore stepped out the door early Wednesday, March 18, 2026, into a sharp late-winter chill, with temperatures hovering near freezing in the upper 20s to low 30s under partly to mostly sunny skies. Light winds keep the first half of the day calm, and the morning commute stays largely dry and clear. By afternoon, a southerly flow nudges temperatures into the low 40s, setting up a steady warmup that carries into the weekend. Skies remain mostly dry through Thursday before rain chances ramp up Friday night into the weekend.
What To Expect Today
Wednesday tops out near 41°F with mostly sunny skies and a light northeast breeze around 2 to 6 mph. Tonight, readings slide back toward the mid 30s with light southeast winds keeping things relatively quiet.
According to the National Weather Service, the broader pattern favors a gradual warmup. Highs climb into the 50s on Thursday, then continue into the upper 50s and 60s by Friday and through the weekend.
Weekend Warm-Up And Showers
The warming trend rolls on into Thursday and Friday, with highs near 51°F on Thursday and around 58°F on Friday. By mid-afternoon Friday, there is a slight chance of light rain, the first sign of a wetter stretch.
Rain becomes more likely Friday night into Saturday, with Friday night lows near 49°F and a 60% chance of rain, so evening outdoor plans may need a backup. Saturday should reach the mid 60s with rain likely before early afternoon, while Sunday looks even milder, potentially reaching the upper 60s with another chance of showers late in the day.
Boaters And Commuters
On the water, small craft conditions are the main concern early Wednesday. Advisories are extended through 6 a.m. EDT on Wednesday, March 18, 2026, for portions of the Chesapeake and tidal Potomac. Gusts up to 20 knots are possible at times this weekend, so boaters should check the National Weather Service forecast before heading out.
For drivers, the rest of the workweek looks mostly dry until Friday night, when light rain and wet roads could slow the evening commute.
Looking Ahead
Once the weekend front moves through, Canadian high pressure drops temperatures back into the 40s early next week, with lower humidity and mostly dry skies on Monday and Tuesday. There is a low potential for a few showers along the Allegheny Front and west of the Blue Ridge early next week, including a slight chance of wet snow in the higher terrain.
Keeping an umbrella handy through the weekend is a smart move, and anyone trying to squeeze in outdoor plans will have the best shot at dry weather Saturday morning.
