National Weather Service has issued an Excessive Heat Warning for Schuylkill County on Thursday.
The warning lasts from Noon until 7 p.m. on Thursday.
The Excessive Heat Warning was issued because NWS forecasts its “Heat Index” to reach up to 110.
There is a Heat Advisory in effect on Wednesday for Schuylkill County and forecasters say “excessive heat conditions” will likely be in place on Friday locally, too.
What is the Heat Index?
The Heat Index is calculated by National Weather Service. It’s also known as the apparent temperature. In addition to the actual air temperature, Heat Index factors relative humidity to determine temperature it actually feels like outside.
Any Heat Index value between 105-110 will likely cause National Weather Service to issue heat-related advisories and warnings.
Actual temperatures in Schuylkill County will only dip to 72 degrees Wednesday night. High temperatures on Thursday should reach 94 degrees during the day. A high temperature of 94 degrees is also forecast for Friday.
This very summer-like air will get out of the way on Saturday, with temperatures only expected to reach 83 degrees.
