...RED FLAG WARNING IN EFFECT LATE WEDNESDAY MORNING THROUGH
EARLY EVENING ACROSS NORTHEASTERN WYOMING AND WESTERN SOUTH
DAKOTA...
.Hot, dry, and windy conditions will support widespread critical
fire weather conditions Wednesday, mainly in the afternoon and
evening. Temperatures tomorrow will range from the 80s to mid 90s
with minimum humidities dropping to as low as 10%. Meanwhile,
southwesterly winds will increase through the morning as a cold
front approaches the region. Sustained winds will be at 20 to 30
mph with gusts of 35 to 45 mph. Scattered thunderstorms are
possible across western to central South Dakota Wednesday
afternoon and evening. These storms may contain cloud-to-ground
lightning and erratic winds with gusts in excess of 50 mph while
producing very little precip. This could lead to fire initiation.
Conditions will improve Wednesday evening as temperatures fall,
humidity rises, and a cold front quickly crosses the area.
