The National Weather Service has issued Red Flag Warnings for July 10 in areas of Wyoming, South Dakota, Nebraska, and Colorado.
Darren Clabo, the South Dakota State Fire Meteorologist, tells us what to expect in his state:
“A Red Flag Warning is in effect for southwestern SD today from 1200 to 2100 hrs. See https://www.weather.gov/unr/ for details.
“A dryline will move pass through southwestern SD at noon today. Following it, temperatures will rise to near 100, RH will drop below 10%, and westerly winds will gust up to 40 mph creating very critical fire weather conditions. Later this evening, a cold front will then move through which will switch the winds to the north but the winds will remain strong through 2200 hrs. No precipitation is expected over southwestern SD with the cold front passage. There will be a ~10 hour window of extremely critical fire weather conditions. Stay aware of your surroundings when on initial attack. This primarily affects Fall River, Custer, and Oglala Lakota Counties.
“Elsewhere across the state, severe weather is likely with large to very large hail, strong winds, and a few tornadoes possible.”
(Red Flag Warnings can be modified throughout the day as NWS offices around the country update and revise their weather forecasts.)
