Baltimore woke up to air you can practically drink on Saturday, with muggy, unsettled weather, temperatures already in the mid- to upper-70s, and scattered showers roaming across the city. Off and on showers and thunderstorms are expected through today and into tonight, keeping the high near 82°F and making outdoor plans a bit of a gamble. Light east winds and some patchy fog are possible overnight, so count on damp roads and slower-than-usual commutes.
Showers Could Drop Localized Torrents
According to the National Weather Service Baltimore/Washington, the chance of rain sits around 60% today and tonight. Most spots should only see a few tenths of an inch, but on Sunday, June 28, a few storms could go overachiever mode and unload 2 to 4 inches in isolated areas, which is plenty to spark urban flash flooding. Lightning and brief, blinding downpours are the main concerns, so keep an eye on short-term radar if your afternoon involves being outside instead of on the couch.
Timing the Rain and the Commute Headaches
Rain chances start early, with showers possible before 8 a.m., then showers and thunderstorms likely through the afternoon before gradually easing toward evening. A few straggler showers may hang on overnight. Where rain exits late, patchy fog could form, which can slow morning travel and snarl the commute. If you are heading to outdoor events, have a backup plan, pack the rain gear, and allow extra time for slick roads.
Heat Cranks Up Next Week and Where to Get Help
Once the weekend’s unsettled pattern moves out, the atmosphere flips the switch to “blast furnace” early next week. Highs jump into the upper 80s on Monday, then peak in the upper 90s to low 100s by Wednesday and Thursday. Forecasters say heat indices could run about 100 to 105°F, with a few readings near 110°F along the I-95 corridor, and nights will not offer much relief. We covered the developing heat threat earlier this week, including details on Baltimore’s Code Red cooling-center program and tips for riding out the heat safely.
How to Handle It
For Saturday and Sunday, plan on interrupted outdoor activities and slower commutes, and be ready to postpone vulnerable outdoor work when storms fire up. Starting Monday, avoid heavy exertion during the midafternoon heat, drink water regularly, check on elderly or at-risk neighbors, and use cooling centers on Code Red days (call 311 for local hours). If flooding or power outages occur, stay out of standing water and treat every downed wire as live until utility crews say otherwise.
