Forecast Discussion

Sunday, September 7, 2025 | Updated 3:00 PM

Periods of sunshine return on Monday and into Tuesday, with ENE flows, cool temperatures in the 70s, and GOOD air quality. Low pressure moving up the East Coast brings clouds on Wednesday with some possible showers. Will have to keep an eye on Canadian firesmoke, which may move in later in the day, but only expecting MODERATE air quality at worst.
