Scattered severe storms are possible after 5 PM across north central Kansas. These storms may form into a line as they move east southeast this evening. Very large hail, damaging wind gusts, and a few tornadoes are the main hazards. Localized flooding is also a concern if storms train over areas that received heavy rain the previous evening. A Flood Watch remains in effect from 7 PM this evening through 7 AM Tuesday morning for areas along and north of I-70. Widespread rainfall totals of 2-4 inches are expected with locally higher amounts could lead to flooding. .DAYS TWO THROUGH SEVEN...Monday through Saturday Gusty south winds return across the Flint Hills Monday morning and afternoon with sustained winds of 20-30 mph and gusts upwards of 45 mph into the early evening. A Wind Advisory remains in effect for Dickinson, Morris, Lyon, Geary and Wabaunsee counties from 9 AM to 9 PM Monday. The greatest chance for severe weather is still shaping up to be Monday afternoon and Monday night. There is good confidence in storms developing over north central KS by the early evening and move across all of northeast and east-central Kansas through the night. Storms will be capable of producing tornadoes, very large hail, damaging winds and flash flooding. People should be prepared for thunderstorms impacting the area. A Flood Watch remains in effect from 7 PM this evening through 7 AM Tuesday morning for areas along and north of I-70. Widespread rainfall totals of 2-4 inches are expected with locally higher amounts could lead to flooding. .SPOTTER INFORMATION STATEMENT... Spotter activation will not be needed.
