Areas of heavy rain are expected in the north and west, with two to four inch amounts in the forecast. Locally higher totals could occur in places. Given this much rain, flash flooding is a concern. Also, there is a risk of severe storms north and west of Little Rock. Storms that become severe will have the potential of producing damaging winds and quarter size hail or larger. .DAYS TWO THROUGH SEVEN...Wednesday Through Monday The atmosphere will remain very unstable on Wednesday, especially over the northwest half of Arkansas. Thunderstorms will remain likely in this part of the state, and could bring additional severe weather and flash flooding. From Thursday through Saturday, the front responsible for the active pattern will slowly wobble across the region from the northwest. While good chances of rain will continue, high water issues and severe storms should be more localized. The front will exit the region by late in the weekend, with thunderstorms becoming isolated. .Spotter Information Statement... Spotter activation may be needed Tuesday night through Wednesday night. && Visit NWS Little Rock on the web. Go to https://weather.gov/lzk. 46/230
