KEY MESSAGES

- 50-80% coverage of thunderstorms today (mainly along/south of I-44) and Thursday (entire area) afternoons with localized heavy rainfall. - Warm with low chance for isolated showers and storms this weekend into early next week, with heat index values around 100 degrees.

SHORT TERM /THROUGH THURSDAY/

Issued at 243 AM CDT Wed Jul 15 2026

A strong upper high over the northern plains will keep an upper that is currently over AR/MS border meandering to the west over the next couple of days.

For today, areas along/south of I-44 will see the greatest coverage of showers and storms at 50-80%, with 10-30% north of there. Some storms are already occuring along the MO/AR border, but greatest coverage is expected this afternoon. MLCAPE values of 1,000-1,500 J/kg and weak shear will prevent any severe weather concerns. However, slow storm motions may lead to very localized heavy rainfall, with REFS and HREF PMM values of 2-3 inches. Any flooding concern would be minor and very isolated. Otherwise, look for highs in the 80s to around 90 today.

Thursday will overall be a very similar setup, but the low will have moved west and closer to the CWA, putting the entire area under the 50-80% storm coverage. Otherwise, all else remains the same as Wednesday.

LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/

Issued at 243 AM CDT Wed Jul 15 2026

Isolated to scattered summer time showers and storms will be a possibility each day in the long term, but most areas will be dry during this period.

NW flow will shift a warmer airmass building over the western US into the area this weekend into early next week. Look for highs in the mid 90s to around 100 Saturday through Tuesday with heat index values around 100 (possibly into the mid single digits above 100). Heat Risk in the major category is expected area-wide Sunday and Monday, with moderate to borderline major Saturday and Tuesday.

Issued at 613 AM CDT Wed Jul 15 2026
