A low pressure system scooting quickly off the coast of Long Island has kept some clouds and showers around early this morning, mainly over New York City and eastward through Long Island. Water vapor satellite imagery (pictured above) shows drier air moving in behind the aforementioned low pressure system, diving southward from New York State and Pennsylvania. The result will be clouds giving way to more sun by this afternoon, as the low pressure moves eastward well off the coast.
In addition to the drier air and northerly wind component this afternoon, warmer temperatures will move in aloft. Forecast models indicate 850hPa temperatures increasing from 12-14c this morning to 15-17c by this evening. High temperatures this afternoon will approach the middle to upper 80’s in many areas, and will be warm even down to the area beaches thanks to the north winds. What starts out as a cloudy day across the east end, will turn into a gem of a Tuesday for the majority of the forecast area. Enjoy!
Today: Partly to mostly cloudy skies will give way to plenty of sun, north winds, and highs in the middle to upper 80’s. A tremendous late-summer Tuesday is on the way. No weather hazards or weather-related travel impacts are expected.T
Tonight: Partly cloudy skies return, and pleasant weather is expected early. However, a few isolated showers cannot be ruled out in the late evening to overnight period. Low temperatures falling into the upper 60’s to lower 70’s.
