If it seems unusually hot in New York City, you're right -- the city is now officially experiencing its first May heat wave in 16 years.
Temperatures in Central Park hit 90 degrees at 1:08 p.m. Friday, following highs of 92 Thursday (a record) and 90 on Wednesday.
Besides being the first in May since 2001, it's the fifth-earliest heat wave in records that date to 1868.
(There was an April heat wave in 2002, which holds the record for all-time earliest.)
There's relief in sight for the weekend, though -- temperatures are expected to be more than 20 degrees cooler.
