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!
