Heat — Nevada, Arkansas

2023-07-19 to 2023-07-21 · Nevada, Arkansas

Wider weather episode

A large upper level ridge of high pressure over the Rockies and Southern Plains weakened its grip slightly on the Four State Region late in the day on July 19th through the 21st, although afternoon temperatures still climbed into the upper 90s each day. A weak stationary front that was present in the preceding days over Central and Eastern Oklahoma into Western and Central Arkansas had dissipated by the 20th, which allowed for better vertical mixing and thus, not as oppressively humid conditions. However, heat indices still ranged from 105-110 degrees across Southwest Arkansas before a weak cool front moved through the region on the 21st.
