Heat advisories issued in the Northeast ahead of severe storms

    Hot and muggy midweek

      A brief cooldown for the Northeast provided for a nice Fourth of July holiday weekend, but the heat is ramping back up.

          High temperatures will be in the 90s, but combined with the high humidity, it will feel much hotter. Dew points in the high 60s make it feel muggy and elevate the risk of heat-related illness.
          When the atmospheric moisture content (es decir. relative humidity) is high, the rate of evaporation from the body decreases. En otras palabras, the human body feels warmer in humid conditions,” the weather service says.
          The heat index is directly related to temperature and relative humidity, thus making heat advisories necessary for the Northeast.

          Afternoon severe storms

          Heat isn’t the only weather risk Tuesday, as the Storm Prediction Center has issued a slight risk for some areas of the Northeast and southern New England.

          This activity is likely to move over the highly urban corridor from Connecticut to New Jersey where isolated flash flooding will be possible into the early to mid-evening hours,” warns the prediction center.
