Mostly sunny skies and lower humidity will make for a pleasant day on Long Island Sunday with the same nice conditions predicted until Wednesday when there’s the first chance of rain, forecasters said.

“There’ll be a very dry air mass” over the next couple of days that’s moving west to east, said News 12 Long Island meteorologist Bruce Avery. He added that the weather will be perfect for giving the air conditioner a break and opening up the windows.

Tim Morrin, a meteorologist for the National Weather Service in Upton, said the high temperatures during the week will be above average. He said the normal high for this time of year is 81.

Sunday’s high is forecast to be around 85 degrees, and at night it will be cloudy and mild with the temperature dropping to a mild 66.

Temperatures in Hicksville, Kings Park, Coram, Babylon and East Hampton were expected to be 87, 86, 85, 84 and 83, respectively.

And for those spending their Sunday on or near the water, there were no marine advisories in effect, visibility will be 10 miles and there was a moderate risk of rip currents. Water temperatures will be between 73 and 77 degrees.

A bright start to the workweek comes on Monday when the sun returns and highs will be near 83 and lows near 66.

More mostly sunny skies come back Tuesday when highs will be near 85 and lows near 69.

On Wednesday expect mostly sunny skies with highs near 85, but get out the umbrella since there’ll be a chance of a thunderstorm. Lows will be near 71.

Higher humidity is ahead for Thursday when it will be mostly cloudy and warm with highs near 86 and lows near 72.

Another chance of a thunderstorm could put a damper on the start of the weekend on Friday when highs drop slightly to near 84 and lows will be near 70.
