Severe weather for December
Severe storm reports were limited in Kansas during December. There were no reports of hail, wind or tornadoes. Severe winter weather was the main feature for the month, with blizzard-conditions across most of the western areas of the state on the 26th and 27th. Sadly, there was one fatality when a stranded motorist died from exposure.
Kansas is drought free!
Despite the warmer-than-normal temperatures, the heavier-than-normal precipitation alleviated the remaining abnormally dry conditions across Kansas. Kansas is now 100% drought-free. The January precipitation outlook is neutral to the east, with increased chances of above-normal precipitation across the west. Given the low normal precipitation at this time of the year, changes in conditions are likely to be slow. The temperature outlook is also neutral across the state.
