WASHINGTON — East Coast residents are waking up to a sharp temperature plunge—up to 30 degrees colder overnight—as a reinforcing shot of Arctic air settles in, with cold conditions expected to persist through next week, according to the National Weather Service.
A broad trough over the eastern U.S. is keeping daytime highs well below seasonal averages, while brisk northwest winds are driving dangerous wind chills, especially during the overnight and early morning hours.
❄️ What to Expect
- Overnight temperature drops: Many areas from the Mid-Atlantic to New England saw temperatures fall 20–30 degrees compared to the previous night.
- Cold here to stay: Forecasts show below-normal temperatures continuing into next week, with little sign of a sustained warm-up.
- Snow showers: Periodic snow showers are expected today through Saturday, with 1–3 inches possible across parts of the north and west, including the interior Mid-Atlantic and portions of the Northeast.
- Dry south and east: Areas along the Potomac and James River basins are expected to remain mostly dry, though cold conditions persist.
- Rivers and ice: Only minor river changes are expected through Saturday, but additional ice formation is possible due to prolonged cold.
🧊 Looking Ahead
The 6–10 day outlook keeps much of the eastern U.S. below normal, reinforcing the message that this is not a brief cold snap. Forecasters emphasize continued caution for overnight exposure, pets, pipes, and travel, especially where lingering snow and ice remain.
