We are starting this week comfortable, but the heat will pick back up as we continue through the week. Monday will be the more comfortable day of the week as we continue to feel seasonable low 80s.

It will be a mostly sunny day with slightly muggy feels heading out the door as compared to what we're expecting in the next couple of days. Overnight low temperatures should remain relatively cool and comfortable in the low 70s.

Tomorrow will be another sunny day with slightly warmer afternoon high temperatures in the upper 80s. The high-pressure set-up that happened just a few weeks ago sets up similarly once again. This will help to funnel in that southwesterly hot and humid weather pattern for the midweek!

A heat advisory has been issued for parts of Long Island as it is expected to feel around 100 on Wednesday. This will not be a long lasting hot and humid stretch as temperatures should drop back to the upper 80s by Thursday and continue to fall through the week.

OTHER WEATHER IMPACTS:

WIND: Wind will pick up at times on Long Island over the next several afternoon. Today won't be much of a concern, but Tuesday afternoon winds will gust up to 25 mph. Winds will pick up again in the afternoon on Wednesday around 30 to 35 mph!

RAIN: There will be little to no rain chances over the next few days! The next chance for rain is more likely towards the end of the week going into the weekend as the upper level weather dynamics driving the weather are expected to change. Exact timing and details will become more clear as we get closer to the end of the week.

TODAY: Sunny, muggy. Comfortable temps in the mid 80s.

TONIGHT: Staying cool. Lows in the low 70s.

TOMORROW: Slightly warmer. Breezy. Highs in the upper 90s.
