Cold Front Brings Heavy Rain, Severe Risk

A slow-moving system will make Wednesday mild and muggy across much of the Northeast and Mid‑Atlantic, with patchy fog and spotty showers. The primary impact arrives Thursday as a cold front and associated low pressure bring widespread, often heavy rain and thunderstorms—some areas could see two main rounds of rain with localized flooding possible. Connecticut could see on-and-off rain up to about 2 inches with possible street flooding, and forecasters say a small tornado cannot be ruled out. Much of Maine is forecast to get about 0.75–1.5 inches (locally higher) before drier air and sunshine return Friday into the weekend. Mid‑Atlantic areas face the risk of isolated strong to severe storms this evening (6–11 p.m.) with damaging winds and a very low (~2%) tornado risk per the SPC. Elsewhere, Acadiana and parts of south‑central Texas (including San Antonio) will see heavy morning showers taper to drier, mostly sunny conditions (some spots could still get 1–2"), Houston should clear to lower humidity by Thursday afternoon, and Metro Detroit is expected to mostly dry out.
