Scattered Severe Thunderstorms
A cold front is moving in Wednesday evening that could trigger scattered severe thunderstorms that'll bring some much-needed rain.
Local
Breaking news and the stories that matter to your neighborhood.
Most of the activity will be north and west of the Interstate 95 corridor. A few storms with heavy rainfall could move across Philadelphia.
The main threats of these storms could be local, damaging winds. The very heavy rainfall could lead to some localized flash flooding with even a brief tornado possible.
We could expect to see the flooding late Wednesday and early on Friday morning with this system because of two rounds of heavy rain.
NBC10 First Alert Weather meteorologist Justin Godynick says that despite the flooding risk, the benefit from the rain will outweigh the flooding threat.
Remnants of Beryl could finally break the heat wave
Heavy rain is expected as we head into Wednesday and through to Friday, but they will do little to break the heat.
Areas north and west of Philadelphia could finally get relief on Wednesday evening as the remnants of Hurricane Beryl are expected to move through bringing chances for flooding and thunderstorms.
Areas with higher risk for severe weather are the upper parts of Bucks and Montgomery Counties along with Berks County and the Lehigh Valley.
Temps on Thursday are still expected to be in the upper 80s.
Tips for dealing with heat, noticing signs of heat-related illness
The heat wave could lead to dangerous health conditions with little relief offered. Be sure to limit time exerting yourself outside, especially during the hottest parts of the day.
Ready.gov shares these heat tips:
- Never leave people or pets in a closed car on a warm day.
- If air conditioning is not available in your home go to a cooling center.
- Take cool showers or baths.
- Wear loose, lightweight, light-colored clothing.
- Use your oven less to help reduce the temperature in your home.
- If you’re outside, find shade. Wear a hat wide enough to protect your face.
- Drink plenty of fluids to stay hydrated.
- Avoid high-energy activities or work outdoors during midday heat, if possible.
- Check on family members, older adults and neighbors.
- Watch for heat cramps, heat exhaustion and heat stroke.
- Consider pet safety. If they are outside, make sure they have plenty of cool water and access to comfortable shade. Asphalt and dark pavement can be very hot on your pet’s feet.
Also, be aware of the signs of heat-related illnesses. A body temperature of 103 degrees or higher; red, hot and dry skin without sweat; a rapid, strong pulse; and dizziness, confusion or unconsciousness can all be signs of heat stroke.
Should you or a loved one have any of these symptoms, call 911 or go to the hospital immediately.

Also, if you do plan to workout outside, doing so either early in the morning or after the sun is down at night could help keep you cooler, but expect to sweat.
A good bet is to find a splash pad or pool to cool off, just be sure to keep drinking water.
