National Weather Service Saint Louis MO
317 AM CST Sun Nov 16 2025

Forecast is based on ignition time of 1200 CST on November 16.
If conditions become unrepresentative, contact the
National Weather Service.

.DISCUSSION...The most notable aspect of today`s conditions is
that humidity levels will be very low throughout the day, with
afternoon minimums dipping into the low 20s. Fortunately,
northerly winds are expected to remain light, which should
mitigate the threat of more erratic fire behavior. Mixing heights
are also expected to be relatively suppressed, and when combined
with the light winds, smoke dispersion may be somewhat limited,
especially at the start of the burn window.

Very light winds and cold temperatures are expected overnight,
but humidity recovery may be hindered by the very dry airmass.
Meanwhile, breezy southeast winds are expected throughout the day
Monday. While humidity is expected to slowly increase, dry air
may linger into the afternoon and create a brief window of
slightly elevated fire weather conditions.
