Miami, FL – Golden light spills across Biscayne Bay this morning as South Florida wakes to another picture-perfect start. Early risers catch a few wispy clouds drifting offshore, while steady warmth builds — a calm, tropical contrast to the turbulent weather unfolding across much of the U.S.

According to the National Weather Service in Miami, temperatures will top out near 80°F today under mostly sunny skies. Winds will stay light out of the north, then shift eastward through the afternoon, helping coastal areas feel a bit cooler. Tonight, lows settle around 70°F with just a few clouds drifting in from the Atlantic.

Sunday through Tuesday will remain nearly identical — warm, clear, and stable — with highs between 80°F and 82°F. It’s classic late-November Florida: ideal for beach outings, boating, or early Thanksgiving prep. No rain is expected before midweek.

By Thanksgiving, however, forecasters expect a national cold front to push eastward, dropping temperatures across the Gulf and Southeast. While Miami should stay mild, the pattern could bring scattered showers Thursday and a slightly cooler trend by next weekend.

Elsewhere across the country, models hint at heavy snow potential in the Midwest and Northeast between November 25 and December 3 — conditions that could ripple into post-holiday travel delays nationwide.

Five-Day Outlook (Miami, FL):

  • Today: Mostly sunny, high 80°F.
  • Sunday: Sunny, high 81°F.
  • Monday: Sunny, high 80°F.
  • Tuesday: Sunny, high 81°F.
  • Wednesday: Mostly sunny, high 82°F.
