Warm air spread across much of the Northeast on Friday, bringing summery weather that is expected to continue through the weekend, with many locations likely to break into the 90s.<\/p>\n
The heat was forecast to ease slightly Monday and Tuesday, and then crank back up by Wednesday, with next week\u2019s hot temperatures likely to be higher and longer lasting than those this weekend.<\/p>\n
While this weekend may feel unpleasant, it\u2019s the heat next week that has forecasters with the National Weather Service sounding alarm bells. With the school year ending and World Cup festivities beginning, more people across the region are likely to be outdoors then, said Scott Kleebauer, a meteorologist with the Weather Prediction Center.<\/p>\n
\u201cWhen we\u2019re starting to message now for something that\u2019s next week, I think you know what that means,\u201d Mr. Kleebauer said on Friday.<\/p>\n
The humidity will make it feel worse.<\/p>\n
Temperatures were climbing on Friday across the Northeast, as winds from the south scooped up warm air and pushed it north. By 2 p.m. Friday, New York City had already reached 87 degrees and Philadelphia 90 degrees.<\/p>\n
The hottest temperatures this weekend were expected on Saturday in most locations, with temperatures climbing as much as 15 degrees above normal for this time of year. Washington, D.C., was predicted to reach the mid-90s, with Philadelphia, New York and Boston likely to hit the low 90s.<\/p>\n
A cold front will bring a chance of scattered thunderstorms and a push of cooler air Saturday night from Baltimore into New England, but the region will continue to hold onto some of the heat on Sunday, with temperatures forecast to be about 10 degrees above normal.<\/p>\n
The weekend\u2019s temperatures will not be nearly as extreme as they can be in the thick of summer, but Mr. Kleebauer said the warmth will feel significant because the weather has been cool in recent weeks and people have not acclimated to summer conditions.<\/p>\n
\u201cIt\u2019s going to feel pretty hot,\u201d Mr. Kleebauer said. \u201cD.C., Baltimore, Philly and New York, it\u2019s going to feel warm in the city.\u201d<\/p>\n
The humidity is also expected to rise, and Saturday will feel stickier than Friday.<\/p>\n
\u201cSaturday and Sunday might be the first taste of humidity, but it won\u2019t be oppressive by any means,\u201d said Matt Wunsch, a meteorologist with the Weather Service office in Upton, N.Y.<\/p>\n
Forecasters stopped short of calling the weekend weather a heat wave.<\/p>\n
