Critical Fire Weather Conditions

High to Very High Fire Danger

Light Snow Tonight into Friday

A Red Flag Warning is in effect for this afternoon and early evening for portions of northeastern Wyoming and southwest to south-central South Dakota. Dry fuels, breezy west winds of 15 to 25 mph with gusts of up to 40 mph, humidities as low as 13%, and a passing cold front will create critical fire weather conditions. Do not burn outdoors. Never throw cigarettes out of a vehicle. Do not drive over dry grass. Don’t be an ignition source.

High to very high fire danger is expected across much of northeastern Wyoming into western South Dakota this afternoon as temperatures climb into the 60s to low 80s, humidities drop to as low as 13%, and breezy west to southwest winds develop. The unseasonably warm temperatures, dry conditions, and breezy winds will combine with dry fuels to create high to very high fire danger. Don’t be an ignition source, do not drive over dry grass, don’t throw cigarettes out car windows, and secure trailer chains.

Rain showers will develop across the area this afternoon as a cold front moves through. The rain will transition over to snow this evening as colder air filters into the region. Many areas will see minor accumulations of less than an inch but the Black Hills and portions of northeastern Wyoming could see 1 to 3 inches of snow. The snow may cause slick spots on roadways and the Friday morning commute may be impacted. Use caution on roadways, slow down and give yourself plenty of room to brake. Monitor SD511 for the latest road conditions.
