KEY MESSAGES

- Dry and seasonably warm conditions can be expected as we go through the remainder of this week and weekend.

DISCUSSION

Issued at 353 AM CDT Tue May 12 2026

Look for convective rainfall to diminish early this morning over southeast portions of the forecast area. Otherwise, the forecast for the next week will feature dry weather as high pressure and anticylonic/subsident flow become the primary weather influences. There will be some concern for fog early Wednesday morning given the clearing skies, light surface wind, and a humid boundary layer, and so will go ahead and message a limited threat for dense fog in the graphics. Fog will need to be monitored for each morning in this return flow pattern. A weak/dry cold front crossing the forecast area Wednesday night will be inconsequential in terms of weather impacts in the forecast area. /EC/
