.DISCUSSION...
...Yellowstone NP and Teton dispatch areas (includes fire weather
zones 140...414...415...and 416)...
Mainly dry conditions with an isolated chance for light showers
across the northern periphery. Relative humidity values above the
20 to 30 percent range with relatively light winds outside of an
outflow wind from the aforementioned showers. Mixing and smoke
dispersal continues to be good to excellent the remainder of
today.
...Cody dispatch area (includes fire weather zones 275...276...
282...283...285...286...287...288...and 289)...
Not as warm this afternoon continues to be the trend with an
isolated thunderstorm chance for much of the area, especially for
the northern sections of the zones. Frequent lightning and some
stronger outflow winds the main hazard through the rest of the
afternoon to early evening ending before sunset. Relative humidity
values above the critical thresholds with relatively light winds
outside of the aforementioned storms.
