LITTLE ROCK, Ark. – Today will be the third day in a row that heat advisories have been issued in the state of Arkansas.
The combination of temperatures in the low to mid-90s and dewpoint values in the mid-70s will create dangerously high heat index values in excess of 100-degrees and likely over 105-degrees. Due to this potential, the National Weather Service has put much of central and northern Arkansas under a heat advisory from 11 AM until 8 PM Friday for heat index values that range from 105 to 109 degrees. For some, heat index values may climb to readings in excess of 110 degrees. For that, an excessive heat warning may be issued.
The National Weather Service may reissue a heat advisory Saturday as temperatures are expected to range from the low to mid-90’s with dewpoints high enough to cause heat indices to reach 105, too.
