Temperatures will warm up today across southeast and eastern Wyoming.  Expect afternoon highs to rise into the 70's and lower 80's, with 60's over the southern mountain ranges.  Partial sunshine and a beautiful start, then watch for developing showers and afternoon/early evening thunderstorms.  Thunderstorm activity later today could be strong to severe, with downpours, strong winds and hail.  Staying warm through the weekend ahead with a lesser chance for showers and storms.
