Crisp Tuesday Morning Gives Way to Mid‑80s Heat Midweek

Tuesday started off feeling oddly autumnal for a September morning in the District – a real bite in the air, the kind you haven’t felt since June 3rd when temperatures finally slipped into the 50s. It was the coolest start to the day in months, and you could see a faint mist clinging to the river as people sipped coffee a little slower.

Come Wednesday, that chill fades fast. The forecast calls for a crisp start, but the mercury will climb quickly, nudging into the mid‑ to upper‑80s by midday. That’s roughly ten degrees warmer than the highs we saw yesterday, and the sun will be out in full force, bouncing off the Capitol’s dome and giving the city a bright, early‑evening glow.

Adding to the warmth, a southerly wind will start to drift in, carrying a touch of humidity from the Gulf. It won’t be oppressive yet, but you’ll definitely feel the difference on your skin. Think of it as a gentle reminder that summer isn’t quite over.

Later in the week, things get a bit messier. Thursday and Friday both bring a rise in humidity and a scattered chance of showers and thunderstorms. The storm chance on Thursday is pretty isolated – mostly hanging out ahead of an approaching cold front that will slide south across the region. By Friday morning that front could still be hanging around, so expect a few more showers before it finally exits.

If the front decides to move out quickly, Friday could dry up in the afternoon, giving way to clearer skies. Saturday should be dry again, with highs settling back into the low 80s – a nice, comfortable temperature after the mid‑week heat. Sunday nudges a degree or two warmer and re‑introduces another round of storm chances as a system drifts in from the west.

Those showers linger into early next week. Monday will see highs in the lower 80s, while Tuesday – the day of the fall equinox – will cool off a bit, landing in the upper 70s. It’s a classic transition period, where the season is literally balancing on a hinge.
