The trend of hot and dry conditions will be expected across Arkansas over the next seven days. Heat index values reach dangerous levels across portions of Arkansas as soon as today with NWS Heat Risk returning to the Extreme category for parts of the state. Unfortunately, chances for precipitation are nearly zero over the next seven days.
Wednesday high temperatures are forecast to range across Arkansas from the mid 90s to around 100 degrees. Thursday morning low temperatures are expected to fall into the low to upper 70s.
Six-day Heat Risk is shown across Arkansas this week. Main takeaways is an increase in coverage of Major to Extreme Category as we move through this week and into the Labor Day Weekend as the area of heat really settles in. This is the result of upper-level ridging building into Arkansas from the west.
A Heat Advisory will be in effect for the Arkansas River Valley into central and eastern Arkansas through Friday evening as heat index values soar between 105 and 109 degrees.
