Temperatures will warm up quickly today, across most of the state.  Expect highs generally in the 80's to low 90's, above average ranges for early July.  Partial sunshine is expected, but we are expecting the chance for isolated late-day thunderstorms.  Thunderstorms will be likely over the northwest mountains, and towards eastern and southeast Wyoming late today and this evening.  Some storms will be strong to severe, especially across the far southeast corner.  Staying very warm through Thursday and Friday, with more late-day thunderstorms and rain showers expected.  Some heavy rain will be possible within thunderstorms for the next couple days.
