The peak of the heat wave takes place today and tomorrow, as more westerly winds and warmer temperatures aloft bring temperatures into the mid to upper 90s across the area, with low 100s possible in parts of NE NJ or NYC. Along with humid conditions, heat index values will reach the low-mid 100s, possibly even higher locally. A cold front will produce thunderstorms on Saturday evening, ending the heat wave, although the severity of the storms may not be as significant as originally forecast.
Wednesday, July 17 Observations:
Hot and humid conditions continued for a 4th consecutive day as a massive ridge continued to dominate the weather pattern.

The hottest temperatures were 97 degrees in LaGuardia and Central Park and 100 degrees in Teterboro.
