DISCUSSION

Issued at 112 AM CDT Fri May 29 2026

With a couple of nearby sfc lows in place across the area and the slow moving H500 trough continuing to lift north over the state, another day of rain and thunderstorm activity is expected. Most likely coverage of precipitation is expected to be across northern and eastern portions of the state. Similar to the last couple of days, some locally heavy rain could lead to instances of flash flooding. These downpours will be influenced by PW values around 2.00" and minimal shear in place. A flood watch remains in effect through the morning hours where some of the heaviest rain fell on Thursday. Attention will need to be paid to north-central Arkansas through the day in case additional heavy rain occurs.

CAM data suggests that after some early morning precip across areas that experienced heavy rain yesterday, additional precip may impact portions of northeast Arkansas. This would favor a lower overall flash flood threat throughout the day as northeast AR has seen less rainfall recently.

Going through the weekend and into early next week, H500 ridging may attempt to build over the state and surrounding areas. This will help reduce precip chances while allowing temperatures to climb. Highs in the lower 90s F and Td values in the lower 70s F will contribute to heat indices above 100 across at least the southern half of the state through Monday.

Confidence isn't very high regarding the overall pattern by the middle of next week as a strong mid-level cyclone over New England looks to work its way south along the East Coast. This will provide NW flow as far west as the Ohio Valley, potentially closer to Arkansas depending on the track/strength of the cyclone. If nothing else, it will work to suppress the H500 ridge toward the west. This setup may allow temperatures to trend closer to normal through the end of the period.
