Tropical Storm Melissa, Coastal Low Bring Rain

A broad storm pattern will bring mixed weather across North America this week, with a developing coastal low in the Northeast tied to the formation of Tropical Storm Melissa offshore that could deliver the heaviest rain mid‑to‑late next week (worst Wednesday–Thursday) before exiting by Halloween. In East Texas, scattered storms are expected to become widespread late tonight into Saturday, with localized rainfall totals of 4–5+ inches and the primary concern being flooding despite a relatively low overall severe‑weather risk. In the Southwest, Arizona experienced brief early‑morning sprinkles and isolated thunderstorms with only trace amounts reported; drier air will move in and cool temperatures through midweek before rebounding into the 80s by the weekend, though forecasters are watching a tropical wave off Mexico that could alter the outlook. Colorado Springs and the Pikes Peak region should see a mild, seasonable weekend with highs in the 60s and a chance of evening showers Thursday into Friday. Other regional notes: Las Vegas has lingering showers through early Thursday, Chicago will be chilly with lows near the low 40s and gusty 30–40 mph winds, and Toronto can expect on‑and‑off showers midweek.
