A chilly night is ahead, with temperatures dropping into the mid–30s for much of the region by early Friday morning. Because the growing season is still active in parts of Southern Maryland, the Eastern Shore, and central Maryland along and east of I-95, the National Weather Service has issued a Frost Advisory for those shaded in blue on the map. Patchy to widespread frost is likely in these areas, which may damage or kill sensitive plants if left unprotected.

Locations west of I-95 have already seen their growing season officially end, but it will still be a cold start for everyone. Skies remain clear and winds stay light—perfect conditions for rapid cooling overnight. If you still have late-season flowers, garden plants, or outdoor potted plants, now is the time to bring them indoors or cover them before temperatures tumble. Warmer afternoons return Friday, but the morning frost will be a noticeable reminder that late fall is firmly settling in.
