KEY MESSAGES

- Strong to severe storms are possible tonight and again Tuesday and Wednesday, with damaging wind gusts the primary hazard.

- Hot and humid conditions continue through Wednesday, with afternoon heat indices of 95 to 110 degrees.

- Widespread rain arrives Wednesday night (70-85% chance) and continue at times through Friday. Cooler weather follows, with highs in the mid 70s to mid 80s.

BEYOND

Another shortwave brings another good chance of rain to the mid-section of the CWA (75-85% from Columbus to Omaha to Des Moines). QPF expectations have remained mostly consistent, but the heaviest axis has shifted from the CWA's mid-section to the northern half of the area. DESI continues with a 60-70% chance of 1"+ over the course of Wednesday and Thursday... but that band of best probability has shifted north by about 70 miles.

With the cloud cover, rain, and easterly flow, temps should be relegated to the 70s in northeast Nebraska on Thursday and Friday while areas closer to Kansas approach 90F.

Regular chances of showers and thunder continue through the forecast period with Friday night looking increasingly wet (65% max PoPs). The overall pattern will transition to a dampened ridging pattern that should leave this CWA near the "ring of fire" and able to tap into monsoonal moisture whenever it is called upon.
