Heat wave continues: Another record-breaking day before cooldown

Weather

NEW YORK — The blistering heat broke records again in New York and New Jersey on Wednesday, according to the National Weather Service.

Record-high temperatures were recorded at Newark and LaGuardia airports. LaGuardia reached 98 degrees while Newark hit 101 degrees, the weather agency tweeted.

It’s the second consecutive day of tied or broken record highs in the tri-state area.

Temperatures on Tuesday topped out at around 95 in Central Park, but it reached 102 in Newark. Add in the humidity, it felt like over 100 degrees across the entire region except for coastal sections.

Excessive Heat Warnings were extended for much of New Jersey through Wednesday where it was expected to feel like 103 or higher.

Elsewhere, including the city, a Heat Advisory continued with the heat index climbing past 100 degrees for the second day in a row.  

Mayor Bill de Blasio warned that Con Edison’s powergrid was on the verge of a widespread failure due to the extreme heat and power usage. He urged New Yorkers to immediately reduce their power usage, turn off any appliances and lights that don’t need to be on, and set air conditioners at a higher temperature to avoid widespread power outages Wednesday night.

Unlike Tuesday, there will be a better shot of some storms in the evening Wednesday, well ahead of an approaching frontal boundary. Much of it will be to the north and west where it could be on the severe side with damaging winds possible. Heading into the evening, the storms could approach the city and coastal sections, but they may not be as strong.  

For the rest of the week, there will be a tradeoff. Instead of the extreme heat, we will get showers and storms as a cold front arrives and slows down as it approaches the coast. Thursday may start out dry, but showers should develop by the midday period. Due to the rain and cloud cover, it won’t be a hot with temperatures in the mid 80s.

The frontal boundary will slow down several disturbances will track along the front bringing some showers from Thursday night and continue into all of Friday. Some heavy downpours are possible and rainfall amounts could exceed over an inch. Due to the rain, temperatures may stay in the 70s all day long.

Conditions should start to improve during the holiday weekend. An upper-level low may keep the risk some widely scattered showers around on Saturday and the threat could continue into early Sunday. The rest of the July 4th holiday looks good as the low departs and the humidity will drop a bit. Temperatures for both days will be in the mid to upper 70s.
