Despite a "slight chance" of rain overnight, Friday should dawn with at least partly sunny skies and comfortably warm temperatures, the first of three pleasant weather days for Long Island, according to the National Weather Service.
Friday should have a high of 82 with a north wind bringing a low of 62 — the coolest evening temperature in recent days following a week of heat advisories and a heat index of between 95 and 100 degrees.
Nevertheless, there are coastal flood advisories in effect for Friday and Saturday night for southern Nassau, the weather service said, from 7 p.m. to midnight.
"Minor flooding is expected in the most vulnerable locations near the waterfront and shoreline," the weather service said. "Expect around 1 to 1½ feet of inundation above ground level in low-lying, vulnerable areas. Some roads and low-lying property including parking lots, parks, lawns and homes/businesses with basements near the waterfront will experience shallow flooding."
The weekend will feature sun and highs right around 80 both days and night lows in the mid- to high 60s.
But then rain — anywhere from a 40% to 50% risk — could fall Monday through at least Wednesday. Forecasters said they welcome the precipitation to help get Long Island out of a drought watch.
"The good thing — it appears like there is a decent chance of the local area getting some much-needed rain," the weather service said.
Highs should be in the upper 70s each of those days.
