Hi,
I'm planning a big family reunion on June 30th. It's scheduled for outdoors. I hoping to use the pool. What do you predict the weather to be like

May 19 or May 25

I'd like to take my family camping in Freehold, Turkey Swamp and can't decide which weekend is best weatherwise. The 19th or Memorial weekend in May. Advise Please!

Outdoor Event

I'm planning a huge party for May 19, 2018. What is the chance of the weather being warm with no rain?

weather prediction

Hi! Our prediction for May 16-21, 2018, in Region 2 (Atlantic Corridor) is “Sunny north, rainy periods south; cool.” Depending on where you are in this region, we predict either sunny or sometimes rainy, but overall, cool in both places. Traditionally, we are about 80 percent accurate. So, if you are in the southern part of the region, chances are about 20 percent for a sunny, warm day. In the north, the chances are a little better, perhaps. We hope that the weather cooperates and that you have a great party!

June Wedding

Our wedding is planned for June 16, what is the prediction for that day and the rest of that weekend?
