After a slight thunderstorm/tornado threat today, the extended heat wave starts tomorrow!

- While most of the action will be north and west of Long Island, the SPC has included Long Island (except for Montauk) in the 2% tornado threat zone. Most of the day will be dry though with a slight chance of a morning shower or a late afternoon or evening thunderstorm. There will also be wind gusts over 30 mph later today and this evening along the south shore of Long Island.

- It will be a 6-day heat wave for many locations starting tomorrow, and it will be humid with warm, muggy nights. The first cold front is Thursday late afternoon or evening with a chance of a thunderstorm, and another cold front possibly for Saturday evening.

- No tropical storms or hurricanes are expected in the Atlantic Basin for at least the next 10 days.
