June 21, 2023 – Wheatland, Wyoming

The second day of a week long chase vacation in late June featured strong easterlies advecting very moist air into the Central High Plains across Colorado and Wyoming. Some places were expected to reach low 70°F dewpoints which is pretty nuts for the area. The Denver Cyclone was expected to be active but really anywhere from Douglas to Denver was looking pretty good. When you get 3,000 J/Kg of CAPE in Wyoming or Colorado, you figure out how to be there.

While tornadoes were unlikely, they could not be ruled out.

June 3rd wasn’t really a chase day. Most of Texas was within a marginal risk with a sliver of slight along the Rio Grande. The rest of Tornado Alley was just in the general thunderstorm outline. Severe weather wasn’t really in the cards. Weak flow across the middle of the country as an omega block persisted caused nebulous flow at 500mb topping out at 30kt over Nebraska.
