NEW YORK (WABC) -- New York City is set for a refreshing taste of fall Tuesday morning as temperatures dip into the 50s for the first time since mid-June.

If the city reaches the forecast low of 57 degrees, it will mark the first overnight temperature in the 50s since June 16. Many suburbs will be even cooler, with lows in the 40s and some of the coldest spots in the Catskills potentially dropping into the upper 30s.

Despite the chilly start, Tuesday will feature plenty of sunshine, low humidity and comfortable conditions. A few patchy high clouds may drift through at times, but skies will be mostly sunny overall. Temperatures will gradually climb through the 60s before reaching the lower 70s during the afternoon, making for a pleasant day that remains cooler than average for mid-September. Air quality is expected to be good, and the UV index will reach 6.

The cool spell will be brief. A shift in wind flow from the south and east will bring slightly milder conditions Wednesday morning, with temperatures around 61 degrees in the city and 50s across many suburbs. Humidity levels will increase somewhat but should remain comfortable. Wednesday will feature a mix of sun and clouds with highs climbing into the mid to upper 70s. While a stray shower could develop in the Catskills, most areas are expected to stay dry.

Temperatures will return to around 80 degrees Thursday under a mix of sun and clouds. A late-day or evening thunderstorm is possible, primarily north and west of New York City, although most locations are expected to remain dry. The greatest chance for stronger storm activity appears to be farther north near the Interstate 90 corridor.

By Friday, a frontal boundary is expected to settle south of the region, bringing moderate to lower humidity and partly sunny skies.

Saturday currently looks dry with increasing clouds, but conditions may become less settled by the end of the weekend. Forecast models suggest showers or a thunderstorm could arrive on Sunday and potentially continue into Monday.
