A week characterized by excessive, in some cases record setting, heat will come to a climax on Friday as temperatures and dew points are maximized ahead of a cold front. West-southwesterly winds will reinforce an already moist and hot airmass – and temperatures are expected to climb near or over 100 degrees in much of the NYC Metro Area and New Jersey on Friday afternoon. The combination of this surface heating and staggeringly high dew points in the mid to upper 70’s will lead to Heat Index values as high as 100 degrees.
The National Weather Service has issued an Excessive Heat Warning for the entire NYC Metro Area through 8pm Friday. The aforementioned combination of heat and humidity will make this final day of the heat wave especially dangerous. Make sure to take all heat related precautions and be prepared for any heat related emergencies. Keep a close eye on the elderly, children and pets. Avoid prolonged exposure to the sun as well as outdoor exercise. Wear loose fitting and light clothing if possible. Most importantly — stay hydrated at all times.
Along the area shores, some relief is expected by late Friday afternoon as a seabreeze develops. Then, finally, later on Saturday a cold front will make its approach towards the area — and is expected to sweep out the excessive heat. Until then, however, try your best to stay cool!
