KEY MESSAGES

- Heat and humidity more typical of early summer can be expected along with increasing rain chances next week.

DISCUSSION

Issued at 246 PM CDT Fri May 15 2026

The synoptic pattern into early next week will feature troughing over the western CONUS and ridging along the East Coast. The resulting southerly low-level flow will bring a surge of deep moisture into the Plains and Mississippi River Valley regions to start the new week. PWAT values of 1.5 inches return to our area Sunday, with heat and humidity bringing chances for thunderstorms back into the forecast. Afternoon SBCAPE values should range from around 1500-2500 J/kg each day, and heat index values will approach the mid to upper 90s. There may be some organization at times which continues activity into the evening hours, but a front isn't expected to move into the region until mid next week, and even then only dip into our forecast area. Apart from rain and thunderstorms, fog may be a concern at times due to the returning humidity. /NF/
