Strong Winds Blast Area - April 15


High Winds Blast Area

April 15, 2006


Overview

Surface low pressure developed across northeast Colorado during the morning hours and quickly traversed northeastward into central Nebraska by the afternoon hours. Showers and thunderstorms developed during the late morning hours on the backside of the low across eastern Colorado and northwest Kansas. Severe wind gusts advanced outward from the thunderstorms resulting in several damage reports across the area. Strong to severe wind gusts also occurred as a result from the gradient wind present from the low pressure system.

Analysis
Radar (12pm MDT)
Satellite (5pm MDT)

In the images above... the radar showed showers and thunderstorms across eastern Colorado into northwest Kansas. Strong to severe winds from the storms raced ahead of the activity, depicted by the outflow boundary. By late afternoon, the satellite displayed severe thunderstorms developing along a dryline in eastern Kansas with an occluding low pressure in central Nebraska. (Click image to enlarge).

Severe Wind Reports



The image above graphically shows the severe wind gusts that were reported across the region during April 15th. Reports which occurred in close proximity to showers and thunderstorms were logged as thunderstorm-related wind gusts. Reports which occurred when the outflow boundary was well-removed from the activity and likely enhanced by gradient winds were logged as non-thunderstorm wind gusts. (Click image to enlarge).
