cloud cover and light winds across all TAF sites for the rest of
today and tomorrow.

.FIRE WEATHER...
Issued at 142 PM MDT Tue Sep 23 2025
High pressure remains over much of Idaho for at least today and
tomorrow meaning dry, warm weather each afternoon. Winds will remain
fairly light today and we will see gusts only about 20 mph in the
afternoons. Min RHs will be on the downward trend for the next
several days with min RHs today and tomorrow around 20 to 25
percent. By Thursday, Friday, and Saturday we will see min RHs fall
back down to around 15 to 20 percent, but we still won`t have enough
wind around to reach any critical fire weather conditions. For the
second half of this week, an area of low pressure remains over the
Southwestern US and we will remain in a mix of zonal flow and weak
high pressure. At this point, it looks like dry conditions will
continue until at least late Sunday, if not Monday, and even then
precipitation chances look fairly low for now.
