Thursday: One more reasonably warm day before possible record heat this weekend

/ June 24, 2026 at 5:51 PM

Another quiet day is on tap for Thursday with high pressure in control. Lows bottom out in the low 70s, warming to around 90° in the afternoon. Dry air (for this time of year, anyway) will hang on for one more day, though it will be a bit more humid than it was on Wednesday. High pressure and warm air aloft should keep a lid on thunderstorms for one more day as well.

Tuesday: Seasonably warm with a few afternoon storms

/ June 22, 2026 at 9:41 PM

Standard summertime fare continues in the forecast for Tuesday with seasonably warm temperatures and a few afternoon thunderstorms. We’ll start the day on the warm side of normal ahead of a stalling cold front, with lows in the mid-to-upper 70s. The record warm low temperature at the airport for June 23 is 78°, set in 2024, and we may get close to that. From there, we’ll warm into the low 90s, but dewpoints in the low 70s will drive heat indices to around 100° at peak heating. We should see a few storms fire along and head of the seabreeze in the afternoon, though the convection-allowing models are rather sparse with coverage. If storms get going, there are some indications that a pocket of dry air in the mid-levels could help produce some gusty winds in addition to the usual heavy rain and lightning threat, so be alert for possible special weather statements or even warnings.

Thursday: Quiet start, but storms return, perhaps with strong winds

/ June 17, 2026 at 10:50 PM

We’re back in the 90s on Thursday as we get a brief lull in between disturbances, but showers and thunderstorms will return in the afternoon and evening as a slug of moisture from what we expect will be the remnants of Tropical Storm Arthur, which was christened earlier today, There will be a risk for a storm or two to produce some damaging wind gusts, but the overall severe weather threat this far to the east is fairly marginal. Will keep an eye out, though.

Thursday: Getting warmer — and there’s more where that came from

/ June 10, 2026 at 11:09 PM

High pressure remains in control across the area, limiting afternoon thunderstorms and allowing heat to continue to build on Thursday. We’ll start in the mid-70s, warming to the mid-90s in the afternoon. Mix in dewpoints in the low-to-mid-70s and that will yield heat indices approaching or even slightly exceeding 100°. And while a brief popup sbower is never fully out of the question this time of year, the vast majority of us will stay rain-free.
