Timeline For Week-Long Heat Wave In Pennsylvania

As you have probably heard, a heat wave is on the way to Eastern Pennsylvania and the entire region.

Forecasters are predicting scorching temperatures above 90 degrees today through the weekend and through next week. And while temperatures will dip slightly mid week, highs in the 90s are predicted through Friday.

In the Northeast, a heat wave is defined as consecutive days with high temperatures at or above 90 degrees. If the forecast is right, we're looking at a week-long heat wave to last through late next week.

The National Weather Service has already issued a Hazardous Weather Outlook, saying Heat Index values will be in the 90s on Saturday and in the low to mid 100s on Sunday, Monday, and possibly even Tuesday.

"Heat related headlines are expected," the NWS said.

The Weather Channel is predicting the hottest days to be Sunday and Monday, when highs will reach 99 and feel even hotter with the heat index.

AccuWeather is advising people of all ages, regardless of their health and physical activity, to stay hydrated and limit alcohol intake, because it can cause dehydration.

In addition to the heat, it will be dry. From Saturday through the Fourth of July, which is Wednesday, there is very little chance of rain in the current forecast, according to the Weather Channel. The NWS says there is a slight chance of showers on the Fourth of July.

Temperatures are predicted to go down to the 80s the following week, The Weather Channel says.
