The Pattern Ahead
An Extreme Heat Warning has been added to the higher elevated of western and northern Arkansas for this afternoon. The forecast high temperatures are expected to be in the triple-digits across much of the state this afternoon. This will be in tandem with oppressive heat index values, which will exceed 115 degrees in some locations. Practicing heat safety on this afternoon is a must. The Extreme Heat Warning will run through 9pm this evening.

Scattered strong to a few severe thunderstorms will be possible on Tuesday evening into Tuesday night across northeastern Arkansas as mounting instability ahead of an approaching cold front will present the hazards of damaging wind gusts and severe sized hail.

High temperatures on Tuesday across the Natural State will be brutal. The majority of locations will experience afternoon high temperatures at or over 100 degrees. Locations that fail to reach 100 degrees will be just shy of the mark in the mid to upper 90s in the higher terrain of the state. Low temperatures Wednesday morning will be comfortable across northern Arkansas as upper 60s to mid 70s are expected to fill in behind a cold front expected to be moving across the state. From along the I-40 corridor into the southern half of the state, low temperatures will not lower as much as this area of the state can expect temperatures on Wednesday morning from the mid 70s to low 80s.

As heat builds across Arkansas , it is important to remember that a closed-up vehicle can heat up quickly without AC. Beat the heat, check the backseat, and never leave people or pets unattended in a vehicle exposed to the elements.

Heat risk is shown in the graphic. Heat will build over Arkansas, especially on Tuesday where major to extreme heat risk is noted across most of the state.

Upper-level high pressure (H) will build into the region over the coming days. Scattered rain chances will decrease each day. Once this takes place, temperatures will climb well into the mid and upper 90s. Heat index values may range from 100 to 110 degrees.
