Rare Christmas Tornadoes and Hurricane Force winds
A wide variety of severe weather occurred across the Central Plains on Christmas Day 2016 as a strong storm system moved quickly through northern Kansas and southern Nebraska. The day began with a line of thunderstorms which produced some tornadoes and damaging wind gusts. Then later on Christmas evening, widespread Hurricane Force winds were recorded for a few hours across the area causing widespread damage. A Christmas to go down in the record books. Christmas Day 2016 brought rare December tornadoes to north-central Kansas and south-central Nebraska. The brief, weak tornadoes developed just before noon along a line of thunderstorms. The first tornado touched down at 11:45 AM approximately four miles northwest of Alton, KS and tracked northeast for 1.9 miles. The tornado was rated EF-0 and damaged trees in shelter belts, fencing, a bin feeder, small shed and soffits and shingles on a home. The second tornado set down at 11:50 AM 2.8 miles south of Funk, NE and tracked northeast for 2.8 miles. The tornado was rated EF-1 and damaged at least six power poles and four center pivot systems. Another tornado briefly touched down and did minor damage to a farm at 12:17 PM approximately 7 miles southeast of Minden, NE. This tornado was rated EF-0. Yet another tornado developed at 12:24pm about 4 miles northwest of Gibbon, damaging multiple power poles and center pivots and destroying a small outbuilding in the Blue Sky Subdivision along is 4.2 mile track. This tornado was also rated EF-0. In Kansas, prior to 2016, it appears at least eight tornadoes occurred in Kansas in December since 1950. The most recent December tornado was an EF-0 in Harper County on December 14, 2014. Prior to that two tornadoes occurred in Cherokee County on December 18, 2002. The latest 'calendar year' tornado was on December 26, 1959 when an F2 tornado occurred west of Talmage in Dickinson County. In addition to the tornadoes, thunderstorms produced damaging winds into the afternoon on Christmas, then during the evening hurricane force winds of 60 to near 80 mph blasted the region behind a cold front. More information on the winds and damage can be found here. |

Hurricane Force Winds Cause Damage Across the Area
Overview
A deep low pressure system formed over Colorado Christmas morning, and it tracked northeast through western Nebraska, roughly along a line from Imperial to Thedford to Valentine. The barometric pressure was as low as 29.06" (986 mb) as the low passed by each of these locations. As this low entered Nebraska, a strong cold front raced east, crossing the area in the late afternoon and early evening hours. Intense winds of 55 to 75 mph snapped trees, downed power lines, destroyed out builds, and whipped through the trees creating a tremendous roar. A couple locations even measured winds between 76 and 79 mph. Two things contributed to the strong winds: 1) Rapidly increasing pressure behind the front, and 2) increased mixing as colder air moved in. Winds were exceptionally strong even down to the lowest 5,000 ft of the atmosphere. Data from the evening weather balloon, launched at Dodge City, indicated winds were 44 kts (51 mph) just 800 ft above the ground, and 57 kts (66 mph) at 1400 ft. These winds were easily mixed to the surface. As for the rapidly increasing pressure, just as one example, the pressure at the Lexington, NE airport increased 0.20" (6.7 mb) in just one hour after the passage of the front. Just three hours after frontal passage, the pressure climbed 0.43" (14 mb). That is extremely impressive.
