Baltimore, MD is heating up fast on this Monday, with highs climbing to near 94°F under mostly sunny skies before a 40% chance of showers and thunderstorms arrives after 3 PM ET — so if you’ve got yard work, a walk along the Inner Harbor, or errands to run, knock them out before lunch and keep an eye on the sky this afternoon.
Today’s Setup
The National Weather Service’s Baltimore/Washington office is watching a decaying cluster of storms sliding across western Pennsylvania and north-central West Virginia this morning, plus another batch of storms over the Ohio River Valley. Their leftover outflow, combined with a developing lee-side trough, is expected to help spark new thunderstorm development across the Baltimore area this afternoon and evening. Forecasters say the atmosphere has the ingredients for a fairly active stretch running through Wednesday, with hot temperatures and high humidity sticking around in the meantime.
Best Window To Be Outside
Morning through early afternoon is your best bet today — skies stay mostly sunny with light southwest wind around 0 to 9 mph. Once you get past 3 PM, storm chances climb, so plan any Patterson Park time, Fort McHenry visits, or Harbor East strolls for the first half of the day.
Storm Risk Tonight Into Tuesday
Monday night carries a 38% chance of storms before 11 PM ET with a low around 75. Tuesday brings another round — a 55% chance of showers and thunderstorms, mainly between 2 and 5 PM ET, with a high near 90. Expect brief downpours and lightning rather than widespread flooding.
What To Wear Or Bring
With the heat and humidity, a lightweight linen shirt is a smart call for daytime plans, and don’t skip the sunscreen during that sunny morning window. Browse our outdoor gear deals for more warm-weather picks.
Tonight’s Big Show, Plus What’s Coming
BTS brings the WORLD TOUR “ARIRANG” to M&T Bank Stadium tonight, right in the window when storm chances are climbing — Get tickets on SeatGeek if you’re headed down, and keep a rain plan handy given the 3 PM storm timing. Looking ahead, Olivia Dean plays CFG Bank Arena Wednesday, August 12 — grab an Olivia Dean t-shirt before the show — and Thomas Rhett hits Merriweather Post Pavilion Thursday, August 13.
Dinner Tonight
With that warm, mostly sunny stretch before the storms roll in, it’s a good night to fire up the grill for burgers, steaks, or grilled chicken with corn on the cob — just get the grilling done before the afternoon storm risk ramps up. An instant-read meat thermometer and a grill brush and scraper set make cookout night easier. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.
Next Few Days
The active pattern continues into Wednesday per NWS Baltimore/Washington, with more rounds of showers and storms possible before conditions trend cooler later in the week. Storms should stay scattered rather than widespread, but keep tabs on the forecast if you’re headed to M&T Bank Stadium for the Baltimore Ravens preseason game against the Philadelphia Eagles on Saturday, August 15 — Official team gear on Fanatics is a good way to gear up beforehand.
