Please help me :) Thank You!

Weather on June 30

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?

The Editors's picture

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?

June 16 Region 2

The Editors's picture

Hello! For June 10-18, 2018, in Region 2 (Atlantic Corridor), we are predicting “Scattered showers, cool.” No matter what the weather turns out to be, we wish you a joyous wedding day! Congratulations!

Accuracy

This seasons almanac has to have a accuracy of less than 50%. I just threw my copy in the fire.

weather forecast

Actually, the past winter has been a pretty good forecast. Not sure if you're reading it right. I'd say maybe 80%.

Help

Tell me it is not true that this may be a rainy summer on Cape Cod. Noah’s ark will be parking in my driveway if this happens!!!
