Issued at 1103 AM CDT Wed Jul 9 2025 An upper-level trough across the Mid-Mississippi Valley stretching south across Arkansas into northeast Texas will allow for increased instability across the region today. At this time, already beginning to see radar echoes along the eastern extent of the trough across portions of Deep East Texas. Convection to increase with the highest coverage across mainly Deep East Texas and north Louisiana this afternoon. Locally heavy rainfall may be possible with some storms due to the increased PW values near 2 inches. Otherwise, with increased instability and cloud cover, temperatures forecast to remain slightly cooler than the expected July highs, averaging around 90 degrees areawide. Conditions to gradually improve though late evening hours with the loss of daytime heating. Temperatures tonight to average in the lower 70s. Upper-trough to linger across the region through Thursday allowing for another round afternoon of scattered convection. Upper-ridge across the Baja peninsula and northeastern Gulf will eventually merge across the southern CONUS by Saturday, resulting in a gradual warming and drying trend each day through the remainder of the week. With the onset of upper-level ridging high temperatures expected to approach the mid to upper 90s across south Arkansas and north Louisiana by Friday afternoon prompting the possibility for heat headlines through the weekend as the upper-ridge becomes centered across the region. Otherwise, widely scattered afternoon showers and thunderstorms possible each day through the weekend into early next week with highs nearing triple digits by Tuesday. /05/ && .AVIATION...
