From the NWS, update for tomorrow.
NWS Cheyenne - Multi-Day Severe Weather Update - June 1st, 8PM
Good Evening,
Here is the latest information on the possible severe weather across western Nebraska and far southeast Wyoming Tuesday through Thursday.
Key Messages:
An isolated supercell or two may develop between 1 and 3PM across southeast Wyoming on Tuesday before moving eastward and northeastward into western Nebraska and western South Dakota.
All modes of severe weather possible: hail (up to 2 inches), damaging winds (60+mph), excessive rainfall and flooding, as well as an isolated tornado or two.
Failure Mode: Tuesday's environment is quite potent, but if the stable air (cap) is unable to be broken, severe storm coverage will be significantly reduced and likely later in the day.
