DISCUSSION

Issued at 123 PM CDT Tue Jun 9 2026

Tonight through Wednesday Night...

Quiet conditions will prevail across our CWA tonight thanks to the subtropical ridge over the southeast CONUS. Sky cover heading into the overnight period will be generally clear. This combined with calm southerly winds will allow for radiational cooling to occur areawide. This will allow for nighttime lows to dip into the low/mid 70s. Similar conditions are expected tomorrow on Wednesday with daytime highs peak into the low/mid 90s. Heat indices will be on the rise Wednesday with heat index values reaching the triple digits mainly for areas along and west of I-55 and down towards the Pine Belt. Areas east of I-55 will see heat index values in the upper 90s. Clear and quiet conditions will prevail across our CWA Wednesday night with lows in the low/mid 70s.

Thursday through Next Tuesday...

Another round of quiet weather is in the forecast as we head into Thursday. Rain chances will start to increase heading into Friday as a cold front over the Central Plains is forecasted to push southeast towards the Lower Mississippi River Valley. Despite the somewhat decent rain chances (PoPs around 20%-40%) on Friday, followed by lower chances of rain heading into the weekend, dangerous heat is still the primary focus for the long term period. There is higher confidence in Friday-Sunday being the best days for heat stress to peak at 105 F degrees. Afternoon guidance continue to highlight peak heat risk during the Friday-Sunday timeframe when highs are expected to reach the low/mid 90s areawide. We will hold off on messaging for dangerous heat in our HWO graphics for right now but will continue to highlight a more general heat threat until we get closer to Friday.

Looking ahead into early next week, another cold front will track south towards the southeast CONUS. This combined with increased flow from the south will help increase moisture and rain chances across our CWA as we go through the next several days. /CR/
