Baltimore is baking under a 102°F Extreme Heat Warning today, with heat index values climbing as high as 111 degrees before scattered showers and thunderstorms move in this afternoon — so get your Fort McHenry walk or Inner Harbor stroll done early and have a shady, air-conditioned plan for the rest of the Fourth.
Today’s Setup
The National Weather Service has an Extreme Heat Warning in effect from 10 AM until 9 PM for the Baltimore area, with 850-mb temperatures supporting another 100-degree day before tropical moisture pushes heat index readings into the 105-110 range. Skies start mostly sunny, but showers and thunderstorms are expected after 2 PM, with a 50% chance of rain and light new rainfall under a tenth of an inch. The Storm Prediction Center has an Enhanced Risk for severe thunderstorms in place for areas east of the Blue Ridge, which includes Baltimore, so keep an eye on the sky for this evening’s fireworks and cookouts.
Best Window To Be Outside
Mornings before 10 AM are your best bet for anything active outdoors — a Patterson Park walk, Inner Harbor errands, or a bike ride along the waterfront — before the Extreme Heat Warning kicks in and before storm chances build after 2 PM. Once the warning starts, move activities indoors or into the shade and lean on hydration breaks.
Heat, Storms & Flash Flood Risk
Tonight stays warm and muggy with a low around 77 and heat index values still near 101, plus scattered storms overnight before 1 AM and again between 2 and 5 AM. Sunday brings a high near 93 with storm chances returning after 3 PM, and the Weather Service’s key messages flag continued severe thunderstorm chances Sunday into Monday along with an increased risk for flash flooding, so watch low-lying and flood-prone spots near the harbor and streams through the weekend.
What To Wear Or Bring
Light, breathable clothing and constant water are non-negotiable today — an insulated tumbler 30oz keeps drinks cold for hours whether you’re at the harbor or the backyard. If you’re watering the lawn or garden before the heat peaks, a soaker hose for garden is gentler on plants than a sprinkler, and moisture absorbing closet packs help with the sticky, humid air indoors. Given the severe storm risk tonight, a DARAN 288Wh Power Station Just $90 for Prime Members is worth having charged up in case storms knock out power.
Gameday & Weekend Events
The Baltimore Orioles host the Chicago Cubs at Oriole Park at Camden Yards on July 7 — grab a Baltimore Orioles jersey or Baltimore Orioles fitted cap and check tickets on SeatGeek. Music fans have the Shakira concert at CFG Bank Arena on July 6 — pick up a Shakira t-shirt and find tickets on StubHub. The PLL All-Star Game lands July 5 at Navy Marine Corps Memorial Stadium if lacrosse is more your speed.
Tonight’s Dinner
It’s too hot to fire up the stove tonight — a cold Thai noodle salad, a build-your-own wrap bar, or smoothie bowls made in a high-powered blender are all easy, no-sweat options. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.
Next Few Days
Sunday stays hot and stormy near 93°F, with Sunday night’s flash flood risk elevated as more storms roll through. The Weather Service expects more seasonable conditions to return by mid-to-late next week, a welcome break after this stretch of extreme heat.
