Stay Safe: Excessive Heat Warning in Effect Sunday and Monday

Extremely hot and humid with hazy sunshine.

When dealing with a heat wave, experts recommend what might seem obvious, but is still important to remember: Stay hydrated, even if you're not thirsty.

Fortunately, a round of thunderstorms will mark an end to the extreme temperatures for the Midwest on Sunday, limiting the duration of this round of heat.

Mayor Lovely Warren has initiated a Cool Sweep Heat Emergency operation in anticipation of forecasted temperatures exceeding 90 degrees. The reported temperature at Logan Airport as of 1 p.m. Sunday was 91 degrees and the heat index was 98, the weather service said.

Kennedy says the weather service could issue a heat advisory for Monday or Tuesday as the index could top 100 degrees.

Temperatures overnight will drop down to 73 degrees with partly cloudy skies.

Unfortunately, Friday and Saturday are expected to be almost as hot, with highs in the mid to upper 90s. With the heat index, feels like temperatures will push back into the triple digits. Heat-related illnesses become likely for heat index values greater than 105 if proper precautions are not taken.

Saturday's record high is 100 degrees set in 1931.

As of Friday morning, Sunday looks like it will bring the most risky conditions, as the high of 98 degrees should officially mark our first heat wave of 2018.

The same, or actually a bit worse, is happening on Sunday, with a forecasted high of 96 and a heat index of 103. Records on Sunday are 97° in Allentown and 101° in Reading, and again records will be threatened, more so in the Lehigh Valley than in Berks County.

If possible, go to an air-conditioned location for several hours during the hottest parts of the day.

The heat will stick around during the first week of July. Keep strenuous outdoors activities between dawn and dusk if possible, stay out of hot cars, and check on the young, elderly, and those with respiratory and heart issues.

It is very easy to get dehydrated when it is so hot and humid. Morning lows will likely fall to between 75 and 80 degrees, according to the Weather Service.

Crank up the AC or head to the beach this weekend because it's going to be hot.

He said there could be an "ever so little" increasing of the heat as the week progresses.
