The first day of summer is upon us and we will be greeted with a nasty little heat wave starting on Sunday and lasting through Wednescday. There is a slight chance at the isolated afternoon thunderstorm over the next couple of days, but we look dry to start the week. The next serious shot at any rain comes Thursday through Saturday of next week as a weak disturbance may impact the area. Stay cool!

Trying something a little different here and using our 5 day for a weekend forecast.

For reference:
-AM Time frame is around 9 AM
-PM Time frame is around 2-3 PM

I know it's not hourly but hopefully can help break things down a bit. There is a slight chance of a afternoon/evening storm both days, but I think they're VERY isolated. Always be mindful of where you live, whether you're in a "HOT" area or what's considered a "COOLER" part of the Island. Humidity does increase this weekend and it starts to get hot by Sunday. -Glen

Good morning and TGIF!! Well....after a hot day yesterday with some evening fireworks, today is a much different day. It will be warm, but a lot less humid as dew points are about 20 degrees lower at 50 degrees, thanks to the front that came through over night. Happy Friday and I hope you enjoy it! -Glen

It's coming....A legit chance for 100 degrees (especially Nassau County). Tuesday is going to be insanely hot, dangerously hot and we shouldn't treat as just "a hot day because it's summer." Weekend should be dry, with an isolated storm chance both days, Sunday more so. Have a good night! -Glen

Here is the next line to watch. This would impact the south shore this time as well if it makes it here. It’s 6:30 right now, so expect things to darken within the next hour or so if it hits. I need to go grill shrimp 🫡. Good luck! -Glen

Storm has weakened to nothing. Sorry east end and south shore! -Glen
