Sizzling temperatures and clinging humidity bathed the region again Sunday as the heat index made it feel like 100 degrees.

But, little by little, some relief is coming.

Long Island is slated to gradually segue from the baking hot temperatures of the long holiday weekend to just above 80 degrees by the end of the workweek, according to the National Weather Service.

High temperatures are forecast to be in the mid- to upper 80s Monday, cooling down to the low to mid-80s by Friday, according to the agency.

David Stark, meteorologist with the National Weather Service's Upton bureau, said the recent hot spell is "not uncommon" for July. And the recent high temperatures aren't necessarily a harbinger of what's to come this summer.

While the heat takes a break, the humidity likely won't, Stark said. Thank the Bermuda High -- a high-pressure system centered on Bermuda that is dragging warm, moist air to our region from the South.

By the end of the week, Stark said, a frontal system from Canada will push the Bermuda High out into the Atlantic, bringing Long Islanders clouds and better chances of afternoon showers and thunderstorms, he said.

Sunday's highs were in the lower 90s but it felt close to 100 degrees, said Joey Picca, meteorologist with the weather service's Upton bureau.

TodayMonday will be slightly cooler, in the mid- to upper 80s, with a 30 percent to 40 percent chance of afternoon precipitation. Lows will be cooler, in the upper 60s to low 70s, Picca said.

TomorrowTuesday will be similar, with highs in the mid- to upper 80s and a chance of precipitation in the afternoon. Lows tomorrowTuesday will be in the low 70s.

Wednesday will cool down slightly, with highs in the low to mid-80s and another chance of afternoon showers and thunderstorms. Lows on Wednesday will be in the low to mid-70s.

Thursday will heat up a bit, with highs in the mid-80s and a chance of afternoon precipitation. Lows will be in the low 70s.

Friday will be in the low to mid-80s, again with a chance of afternoon precipitation.

While the air won't ever feel dry, it should become less muggy as the week goes on, Picca said.
