Tonight will be quiet across Long Island with a mix of clear skies and mild temperatures for early November. There could be some patchy fog overnight, which could be dense at times towards morning.

After a cool start Wednesday morning, temperatures will surge into the upper 60s and lower 70s during the afternoon, making it the warmest and nicest day of the week. Sunshine and well above-normal temperatures will create excellent conditions for outdoor activities, with readings running 10 to 15 degrees warmer than what is typical for this time of year.

Thursday will remain unseasonably mild, although increasing clouds and a strengthening southerly breeze off the ocean will keep temperatures a bit lower than Wednesday's peak.

The weather pattern turns much more active late Thursday night into Friday as a cold front approaches from the west. Confidence is increasing that a band of moderate to heavy rain will develop across the region, with some of the highest rainfall totals potentially occurring across Long Island.

Current projections suggest that many areas could receive 1.5 to 2 inches of rain, while localized amounts of 3 inches or more cannot be ruled out if the heaviest rain band sets up over the island. While widespread significant flooding is not expected because conditions have been quite dry recently, localized poor-drainage flooding and some basement flooding could occur in the heaviest downpours.

The steadiest and heaviest rain should begin to wind down by Saturday morning, although a few lingering showers may persist into part of the weekend.
