Long Island commuters can expect a foggy commute Monday morning, according to the National Weather Service, which Sunday night issued a dense fog advisory warning of reduced visibility.

Fog was expected to roll in Sunday night and last until 9 a.m. Monday as temperatures dip into the low 60s, said Faye Barthold, a meteorologist with the Service.

"For commuters this means a visibility of a quarter-mile or less," Barthold said. "Slow down, leave some extra space, use your low beams, you could be driving into and out of fog."

A separate marine fog advisory was issued spanning Sunday night until noon on Monday. Weather service officials also issued a small craft advisory warning of hazardous conditions on the water due to high wind gusts and waves ranging from 4 to 7 feet.

A cold front is expected to move in Tuesday, bringing a chance of showers and thunderstorms.

"There may be an isolated thunderstorm late in the day Tuesday," weather service meteorologist Matthew Tauber said. "We're looking at about 2 p.m. into early evening, then by midnight there could be a tenth of an inch [accumulation], but nothing heavy."

Tuesday night will be cooler, but the front should be through by then and lows will be 57 to 58 degrees.

"We'll see the remnants of Tropical Storm Ana on Tuesday," said News 12 Long Island meteorologist Patrick Cavlin. Ana, upgraded from a subtropical storm early Saturday, was expected to be very near the coasts of South and North Carolina early Sunday. It is forecast to turn toward the Northeast, but stay far offshore of Long Island.

Wednesday through Friday, skies will be sunny, with cooler temperatures than at the start of the week.

Highs Wednesday will be 67 to 69 degrees across the Island with lows of 45 or 46.

Thursday's high will be 65 to 68 degrees, with lows of about 45 or 46.

For the start of the weekend Friday, look for highs in the mid-60s, with lows from 49 to 51 degrees.

If you're wondering what has happened to spring, Tauber said some dreary, humid and wet conditions are not usual.

"The week will be fairly typical," Tauber said. "Normal highs are around the mid-60s and lows are in the mid- to upper 40s. "In spring it's typical to get the foggy nights.
