Sunny skies and temperatures in the 80s are expected this weekend on Long Island.

The National Weather Service on Friday evening was predicting a high temperature Saturday of about 84 degrees — 4 degrees higher than the normal high for the date in Islip — with a calm wind becoming south around 6 mph in the afternoon.

Along with the warm temperatures and lack of a strong wind comes a state Department of Environmental Conservation air quality alert in effect from 11 a.m. to 11 p.m. Saturday on Long Island with ground level ozone readings expected to be elevated.

The state Department of Health recommends that individuals consider limiting strenuous

outdoor physical activity to reduce the risk of adverse health effects. The department also noted that the very young, and those with preexisting respiratory problems such as asthma or heart disease may be especially sensitive to the effects of elevated levels of pollutants.

The weather service said Saturday night should also be mostly clear, with a low temperature of about 66 degrees.

The high temperature Sunday is expected to be about 83 degrees under sunny skies.

Showers are predicted for Monday, mainly after 8 a.m. The chance of precipitation is pegged at 80%.

Clear or mostly clear skies are forecast for the rest of the workweek.

High temperatures should be in the high 70s Monday, Tuesday and Wednesday, and in the low 80s Thursday and Friday, the weather service said.
