A Flash Flood Watch remains in effect until 10 AM today. Continued showers/storms with heavy rainfall could lead to localized flash flooding, especially in areas where activity has been ongoing through the night. Severe potential is not high with this activity; primary threats remain heavy rainfall and strong winds.
There is a marginal (Level 1/5) risk for severe storms today, generally south of I-70, during the afternoon/evening. Confidence is not high in the exact timing/location of activity today, but primary hazards are expected to be heavy rainfall and strong/severe winds.
Looking ahead, there are additional chances for showers/storms through late week, with lower confidence in severe threats associated with activity. Heat/humidity builds into early next week, with heat indices rising into the 90s and potentially rising as high as the triple digits. Any precipitation potential could dampen temperatures.
