Fire Weather Planning Forecast for Eastern/Central MO and Southwest IL
National Weather Service Saint Louis MO
113 AM CST Thu Feb 19 2026
...RED FLAG WARNING IN EFFECT FROM NOON TODAY TO 8 PM CST THIS
EVENING...
Conditions have dried effectively today with deep mixing under a
clear sky and many locations have dropped below 20% RH. A dryline
will move through the region tomorrow, with the risk for showers
and thunderstorms ahead of it and dry fire weather conditions
behind it. For a discussion on the severe potential please refer
to the Area Forecast Discussion.
The dryline is expected to clear Missouri around noon Thursday,
advancing into Illinois during the afternoon. Dry conditions with
RH values reaching minimums in the 20s to the upper teens will
prevail. Elevated winds above 15 mph sustained and gusting to
near 30 mph are expected as well from deep mixing bringing winds
to the surface. Ensemble guidance indicates the highest
probabilities (50-70%) for exceeding Red Flag criteria exist
across northeast, central, and portions of southeast Missouri
which will see the passage of the dryline first. Conditions are
expected to be drier and warmer than the ensemble guidance
indicates, so we have leaned on the more extreme ends of the
forecast.
Temperatures will cool with sunset, resulting in increasing RH
values despite winds keeping the lower atmosphere relatively well
mixed. A cold front will push through the region overnight,
shifting winds to the northwest and bringing cold air back to the
region. Cooling conditions and relatively higher minimum RH
values (30s-40s) will prevail through the weekend.
