.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/

A brief period of fog is possible around daybreak Saturday morning

the area with a potential for some higher wind speeds up into the
mid teens in areas within and around the Delta. Otherwise, VFR
conditions are anticipated through the TAF period. /OAJ/
