241 AM MDT Thu Aug 21 2025
.DISCUSSION...Fire weather concerns are expected to be near nil
through the coming week as moisture returns and keeps RH values
above critical thresholds. We may see some teen to low 20% values
for today in our far western zones, but this will be the lowest of
the next week as monsoonal moisture brings our values back up into
the 40-60% range by early next week. Could also see a very
isolated dry thunderstorm in this region as well, but that risk is
too low to warrant a red flag warning as well.
