Today brought temperatures into the lower 90s in parts of the immediate NYC area, but temperatures will only get warmer. Tomorrow will bring 850 mb temperatures near 20-21c, which combined with a WSW wind will allow temperatures to reach the 90s across most of the area. Mid to upper 90s are expected in the immediate NYC area, with Newark getting close to the 100 degree mark. The WSW wind will also allow parts of Long Island away from the southern coast to reach the lower to mid 90s, with similar temperatures expected in southern Connecticut as well.
Wednesday night will remain mild, with lows only as low as the upper 70s in NYC, already warming well into the 80s by the morning hours. Thursday will bring slightly warmer temperatures, with a few places in NE NJ potentially reaching the 100 degree mark. Humid conditions are expected as well, with a heat index up to 105 degrees possible.
