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.

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.

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.
