July 28, 2018 – CO/NE/WY Tri-State Area

Severe storms were expected to fire along the Front Range in Colorado and migrate eastward throughout the day. With high CAPE values and moist dewpoints expected in the Nebraska Panhandle area, this appeared to be a relatively favorable area for supercells and possible tornadoes with the easterly upslope flow.

After a stunning chase near Laramie, I drove up to Buffalo, Wyoming expecting to play in Montana on the 7th. After reviewing data in the morning I had two targets in mind: the northern play up by Billings where higher dewpoints were expected along the US 212/I-94 corridor but a quick transition to linear mode was expected; or stay in northeastern Wyoming where a chance at more discrete storms in lower boundary moisture was a possibility.

After the last chase on the 3rd in New Mexico proved somewhat successful, I spent the 4th repositioning north from New Mexico to South Dakota. The plan was to chase North Dakota on the 5th, but despite a 2% tornado risk near Bismarck, that day ended up being a bust.

June 12th was shaping up to be the most significant severe weather outbreak in the high plains in 30 years. The setup favored supercells throughout eastern Wyoming into Western Nebraska. A trough was progged to amplify and eject across the high plains while strong mid level south-westerly winds overspread the area atop rich low-level moisture advecting into the area via an upslope regime.

May 31, 2014 – What am I doing in Wyoming??

May 31st was the second day of a 9 day mini-chasecation. The first couple of days featured a small shortwave trough traversing the northern part of the High Plains and Black Hills which provided slight chance opportunities at severe weather around the Montana, South Dakota and Wyoming areas. An area of low pressure was forecast to strengthen over north central Wyoming with a diffuse front stretching east into South Dakota and a trough extending from the low south into eastern New Mexico.
