A weak frontal boundary that pushed through Central Florida overnight reaches South Florida today, and drier air finally follows: humidity begins dropping Monday afternoon and evening, with overnight lows in the low to mid-70s and mostly sunny skies most of the week. Highs stay slightly above average for mid-October — around 90°F.
Monday can still bring a brief isolated shower, especially inland, as the front passes. Rain chances remain low through Wednesday, then climb to about 40% Thursday and 60% Friday as humidity returns and another front approaches. The National Hurricane Center is only watching a small low-chance disturbance in the far eastern Atlantic — no threat to land.
One caution: it is king tide season, and a coastal flood statement runs through Monday morning, with more rounds possible. High tides can put isolated minor flooding on coastal streets even on rain-free days. Never drive through flooded roads, and avoid touching floodwater — it can carry sewage and bacteria. West Palm Beach should see about 87°F today with just a 30% chance of a morning shower.
