Desert in the cities: Why NYC and Philly umbrellas are collecting dust

We have to go back to last month to find the last instance of measurable precipitation in New York City, N.Y., and Philadelphia, Pa., dry streaks that will find their places in the record books

The Big Apple, home to nearly 10 million people, is in the midst of one of the longest dry stretches on record, dating back to 1869.

Sept. 29 was the last time rain fell on the streets of New York City, N.Y.

Although the all-time record of 36 days is likely to remain out of reach, catching second place at 28 days could be in the cards.

Heading through the final 10 days of October, the next chance for rain will come with a cold front on Wednesday night. Being at the southern end of the front, parts of the city will remain dry. By Wednesday, it will be the longest dry stretch for New York City since May 2001.

Along with the Big Apple, Philadelphia, Pa., is also in the running for a rainless October. That achievement will be the first for any month of the year.
