.DISCUSSION...
Minimal fire weather concerns today through the weekend behind a cold
front that brought widespread, accumulating snow to the region. Minimum
humidity values will remain in the 40s to 70s today, with slightly
lower values, around 20 to 40%, this weekend. However, any snow pack
and any melting snow will increase ground moisture, decreasing fire
weather concerns despite the lower humidities this weekend. Winds will
be fairly calm, per Wyoming standards, today through the weekend. Warm,
dry conditions return next week, so fire weather concerns will return.
