Heaviest concerns are focused on heavy rain and localized flooding, including parts of southern Missouri. A flash flood warning was issued for a portion of Henry County Thursday night, and the rain is expected to persist for several more hours—especially south of the metro.
Over Kansas City itself, overnight showers should be more scattered and are not expected to bring damaging winds, large hail, or tornadoes. Still, brief downpours could leave standing water on roads. By Friday morning, organized rain should be winding down, with skies gradually clearing through late morning and afternoon; patchy fog and leftover showers remain possible.
Temperatures will be cool for late June, with a forecast high of 78 degrees Friday after starting in the 60s. Saturday brings a faster warmup into the mid-80s, and by Sunday summer heat returns with highs in the lower 90s and heat index values near or above 100. The hot, humid pattern is expected to continue into next week and through the Fourth of July holiday weekend, with mostly dry conditions.
