Increasing clouds through tonight, temperatures in the 60s.

Saturday will be the pick of the weekend with dry and pleasant conditions. High pressure will gradually move northeast and away from the region, setting the stage for a much different Sunday. Be mindful of all beach warnings, as there have been ongoing bacteria-related concerns.

Sunday will turn more humid and unsettled. Humidity will gradually build Sunday morning as the departing high allows a southwest flow to develop.
An area of low pressure will move west to east across the region, bringing increasing chances for heavy rain, gusty winds and embedded strong thunderstorms late Sunday into Monday.

The heaviest rain is expected after 8 p.m. Sunday and could continue through around 8 a.m. Monday, potentially making for a messy Monday morning commute across the Bronx and New York City.
Rainfall totals will depend heavily on the exact track of the low. Localized flash flooding is possible, especially in areas that see the heaviest downpours or repeated rounds of rain. Urban and poor-drainage areas will be particularly vulnerable.
Rainfall: Around 1–1 1/2 inches, with locally higher amounts possible
Flooding: Localized flash flooding possible
Wind: Breezy, with overnight gusts up to 25 mph
Storms: Embedded strong thunderstorms possible
Main concerns: Heavy rain, localized flooding and a difficult Monday morning commute
Weather conditions should gradually improve throughout Monday, although some showers could linger early.
Monday night turns mild and quieter, with temperatures in the mid-60s and few clouds around.
Behind the system's trailing cold front, we should get a break from the rain on Tuesday and Wednesday, bringing a quieter stretch of weather for the middle of the week.
