Forecast Update

Issued at 948 PM EDT Tue Oct 20 2026

Similar to recent evenings, clear skies and light winds have led to a rapid temperature fall, especially in favored cold spots. Adjusted hourly forecasts to match current observational trends. Also nudged down low temperatures as well, mainly in those favored cold spots.

Patchy ground fog will likely develop later tonight. However, the more widespread fog expected to develop from low level moisture advection from the northeast will likely remain out of the local area.
