Pressure and weather in Big Flats

Winter systems crossing the Northeast and occasional coastal lows can change pressure in Big Flats, with local valley temperatures affecting precipitation type. Summer valley fog can form during quiet conditions, so fog by itself should not be read as evidence of an approaching low.

What this means for you

If mornings in Big Flats seem headache-prone, track sleep timing and symptoms as well as the pressure curve. This helps you compare a foggy but stable morning with a genuinely changing frontal pattern.
