A weak low pressure was forecast to translate from Colorado into Nebraska, along with it a warm front stretching across southern Nebraska and a trailing cold front south through Colorado. Dewpoints in the low 60°F’s south of the front with cool temperatures aloft set the stage for moderate instability as MLCAPE values would climb near 2,000 J/Kg. Any backing along the front would amplify the tornado chances.

June 15th offered an opportunity for a relatively local chase. A remnant MCV from overnight convection was present in west-central Nebraska and a frontal boundary extended from a low in Canada south across Nebraska then southeast into the Ozarks. Daytime heating was forecast to promote strong instability along and north of the front.

June 7th was one of those days that ends up being a great chase even without tornadoes. Southerly surface winds were forecast to transport moisture north into Nebraska bringing dewpoints into the upper 50°s to near 60°F in the Sandhills. MLCAPE values were expected to reach 1500 J/Kg. Storms were expected to initiate in north-central Nebraska and migrate southeast eventually growing upscale overnight.
