Excessive Heat Warning:

Issued at: 3:34 am EDT on July 24, 2016, expires at: 6:00 PM EDT on July 25, 2016
  • ...Excessive heat warning remains in effect until 6 PM EDT Monday...
  • temperatures...highs in the mid to upper 90s through Monday. Lows in the 70s...however in the highly urbanized areas such as Center City Philadelphia the temperature at night may not drop below 80 degrees especially Monday night.
  • Heat index values...peaking between 100 and 105 degrees Monday afternoon. The dew points are forecast to decrease some during today...resulting in heat indices peaking right near the air temperature.
  • Impacts...the excessive heat will create hazardous conditions. The potential for heat related health issues will be high... especially for the elderly and for those already in poor health.
  • The multiple days of excessive heat will greatly affect those who are attending outdoor activities... especially events with large groups of people that are gathering in the direct sun. Visitors not acclimated to the heat in our region this Summer have a greater risk of being affected. Precautionary/preparedness actions... An excessive heat warning means that a prolonged period of dangerously hot temperatures will occur. The combination of hot temperatures and high humidity will combine to create a dangerous situation in which heat illnesses are likely. Drink plenty of fluids...stay in an air-conditioned room...stay out of the sun... and check up on relatives and neighbors. Take extra precautions...if you work or spend time outside. When possible... reschedule strenuous activities to early morning or evening. Know the signs and symptoms of heat exhaustion and heat stroke. Wear light weight and loose fitting clothing when possible and drink plenty of water. Young children and pets should never be left unattended in vehicles under any circumstances. During warm or hot weather car interiors can reach lethal temperatures in a matter of minutes. To reduce risk during outdoor work... the occupational safety and health administration recommends scheduling frequent rest breaks in shaded or air conditioned environments. Anyone overcome by heat should be moved to a cool and shaded location. Heat stroke is an emergency... call 9 1 1.

***EXCESSIVE HEAT WARNING IN EFFECT FOR THE GREATER PHILADELPHIA AREA THROUGH MONDAY AFTERNOON***

***HEAT ADISORY IN EFFECT FOR PARTS OF SOUTHEASTERN PENNSYLVANIA AND MOST OF NEW JERSEY FROM MONDAY MORNING THROUGH MONDAY EVENING***

With the heat this weekend, make sure you are staying hydrated, wearing light clothing and staying in air conditioned areas. Please take care of pets and check on children and the elders. The UV index this weekend will also remain high so try to stay out of direct sun, frequently apply sunscreen and wear sunglasses and a hat.

Today is another mostly sunny day as high temperatures reach the mid 90s. The record for ABE is 95 degrees (set in 1999) and 96 degrees for RDG (set in 2010), so we could tie these records. Skies continue to stay clear to partly cloudy overnight with temperatures only dropping to the lower 70s. There also could be a stray shower or t-storm in spots this evening, but for the most part, most will stay dry.

The heat sticks around for the week, so expect highs to soar into the 90s. Monday will be especially humid with a shower or thunderstorm later in the day. Any storm could be locally heavy and gusty. The greater Philadelphia area may be feeling like 100 to 105 during the afternoon and the rest of the area may be feeling close to 100 degrees.

But the rest of the week is looking partly to mostly sunny for now. Our next below 90 degree day may be on Friday and into next weekend.
