Fire Weather Planning Forecast for Eastern/Central MO and Southwest IL
National Weather Service Saint Louis MO
934 PM CDT Sat Apr 4 2026
Cool and dry conditions are expected for most locations through
Tuesday. The one exception is the low chance for light rain/snow
over sections of central/northeast Missouri Monday night.
Temperatures will largely be in the 50s/60s for highs and 30s/40s
for overnight lows. This is likely to be the greatest stretch of
dry weather with minimum relative humidity ranging from 50-70%
today dropping to 30-50% through Sunday through Tuesday. Mixing
heights generally improve over today with peak heights of
4,000-5,000 feet Sunday and 3,000-7,000 feet Monday. The greatest
heights are favored near and east of the Ozarks in south-central
and southeast Missouri. However, fair ventilation rate Sunday
range from fair to poor Monday as cloud cover increases from
northwest Missouri into central and northeast Missouri.
