Warmer and Rainier?

I'll be traveling from DC to Hatteras for two weeks (yay!) from May 4-18. Does warmer and rainier just mean hot, wet weather at the beach? Last year, about the same time, didn't really warm up until the last few days. Any way of knowing more about coastal NC in May?

Outdoor wedding

Having an outdoor wedding early November of 2019 near Greenville NC. Curious as to any insight on weather as you never know in eastern NC. Could be 75, could be 35!! Hoping it’ll be at least dry!

August weather

When is the best weekend in August of 2019 to have an outdoor party?


I beg to differ

Wedding last two weekends as options

Options as best weather in August 2019 for a wedding. Last two weekends in the month. Who knows suits for outdoor event

Weather in D.C for spring break?

I am travelling overseas and I am leaving from Washington Dulles and the last time I went, it was so hot here in NC and when I came back it was so cold and windy, we had turbulence and I almost froze! How will it be this year. I am travelling leaving April 14 and returning on April 21. I only want to know the weather in D.C those dates.

Why so much rain?!

It’s been really rainy in South Georgia. Why are we getting so much rain?! I’m about to float away.

why rain?

The Editors's picture

Even a weak EL Niño, such as exists in the Pacific now, can bring a lot of rain to the southland…as we predicted ;-)

Oh God

Plz make the rain stop I can’t swim


Will we get another good snow before winter is over? I love snow and the kids really want to play in it again.
