A few areas may receive heavy rainfall with amounts of 3 inches or greater. These amounts could lead to significant ponding of water in low lying areas and localized flash flooding. The heavy downpours will also impact travel today with reduced visibility and could lead to hydroplaning.
Severe Thunderstorms are also possible today, with the threat mainly from 11 AM until 6 PM. A few tornadoes, damaging winds and large hail are all possible.
