FTB 06-28-2017: A Few Severe Storms Out East; Extreme Fire Danger West

Issue Date: Wednesday, June 28th, 2017
Issue Time: 11AM MDT

— Flooding is NOT expected today
Extreme fire danger for western Colorado

There will continue to be contrasting weather stories across our state today, where the weather never ceases to amaze. Regarding rainfall chances, a marginal amount of low-level moisture will hold on during the afternoon and evening hours along the KS/NE borders, which combined with favorable shear profiles could produce severe storms. Large hail, gusty winds and a tornado threat will be in the realm of possibilities today. Very short-duration heavy rainfall will be possible, but flooding is NOT expected.

Perhaps the bigger story, however, will be the extreme fire danger in the western part of the state where low relative humidity (see water vapor image below), gusty winds and hot temperatures will create a dangerous situation for spreading fires. Hikers/campers – please be cautious.
