A Flash Flood Watch has been issued for Whiteside County through 10am Sunday...
A line of non-severe thunderstorms is currently working into the local area this morning. No severe weather is expected with this activity, but heavy rains and frequent lightning will be likely.
Once this activity clears by the afternoon, we'll see some areas of sunshine with highs rising into the upper 70s. Even a few upper 80s are likely in areas that remain clear the longest. More showers and storms will likely develop by the early evening as a front and increasing amounts of energy arrive.
Building on some of the warmth and sunshine this afternoon, that energy will be used to create a few strong to severe thunderstorms after 6pm this evening. The main threats will be very similar to Thursday night, large hail and damaging winds. An isolated tornado or two cannot be ruled out, especially in areas where the warm front is present.
Additional rounds of heavy rain are likely with these storms tonight, and that's why a flash flood watch has been issued. The ground is already fairly saturated from the heavy rains this morning and any additional rain will likely run off into area creeks, streams, and rivers.
Be prepared for rapid rises in these areas.
