HOT SATURDAY WITH A RISK FOR STRONG STORMS TONIGHT

Long Island will experience another hot day Saturday with hazy sunshine and temperatures climbing into the upper 80s and lower 90s. Most locations will remain dry through the daytime hours before the chance for thunderstorms increases this evening.

The Storm Prediction Center has placed western Suffolk County under a Level 2 out of 5 Slight Risk for severe weather, while eastern Suffolk County remains under a Level 1 out of 5 Marginal Risk. Thunderstorms are expected to develop after 7 p.m., with the greatest potential for severe weather focused across western portions of Long Island.

The primary threats include damaging wind gusts between 50 and 60 mph, small hail, frequent lightning and torrential downpours. Localized flash flooding is also possible where the heaviest rain persists. While not everyone will experience severe weather, residents should monitor conditions closely through the evening hours.

AIR QUALITY ALERT REMAINS IN EFFECT

An Air Quality Alert remains in effect due to elevated levels of ground-level ozone. Sensitive groups, including children, older adults and those with heart or respiratory conditions, should limit prolonged outdoor activity during the hottest part of the day. Everyone is encouraged to stay hydrated and take breaks when spending extended periods outdoors.

WARM AND DRY SUNDAY

The threat for storms ends overnight, leading to a quieter finish to the weekend. Sunday will feature a mix of sun and clouds with warm and humid conditions. Morning temperatures will start in the 60s and lower 70s before climbing into the mid-80s during the afternoon. Dry weather is expected across the island.

BEACH AND BOATING FORECAST

Ocean water temperatures remain cooler than average for early June, generally ranging through the mid- and upper 50s.

A high risk for dangerous rip currents remains in effect Saturday at all Atlantic-facing beaches. Conditions improve slightly Sunday, but a moderate rip current risk is still expected. Swimmers should use caution and swim only where lifeguards are present.

Boaters should also exercise caution as seas become rougher this afternoon with increasing southwest winds.

NEXT WEEK

A prolonged stretch of mainly dry weather is expected through much of next week. High temperatures will begin near 80 degrees Monday before steadily warming through the week. By late week, temperatures could once again climb near or above 90 degrees, running well above the typical highs in the 70s for this time of year.
