NEW YORK - The calendar says May, but it has felt a lot more like June across the five boroughs Wednesday.

Temperatures topped 90 in parts of the city, including at LaGuardia Airport, which hit 93 degrees, a new daily record high for May 17.

Temperatures reached 89 degrees at Central Park. They reached 77 degrees at JFK.

The forecast also calls for a high of 93 degrees on Thursday.

The city's last 90-degree day before Wednesday was on September 14.

An air quality alert is in effect citywide until 11 p.m. An air quality alert will also be in effect Thursday from 11 a.m. to 11 p.m.

People with respiratory issues should avoid strenuous outdoor physical activities.

More seasonable weather, with temperatures in the 70s, is expected to return this weekend.
