Click to show details...RED FLAG WARNING IN EFFECT FROM 2 PM THIS AFTERNOON TO 7 PM CDT THIS EVENING FOR STRONG WINDS AND LOW RELATIVE HUMIDITY FOR FIRE WEATHER ZONES 012, 020, 021, 022, 031, 032, 249, AND 258... .DISCUSSION... Issued at 410 AM CDT Wed Sep 30 2020 Strong gusty winds continue to develop this morning. As temperatures warm, dry air from aloft is expected to mix to the surface leading to relative humidities falling to 20 to 25 percent south of I-90. Have issued a red flag warning for expected extreme fire conditions this afternoon. North of I-90, relative humidities are not expected to fall as much, but the strong gusty winds will still create elevated fire weather concerns. Winds will slowly decrease through the day on Thursday as surface high pressure builds into the western High Plains. People are urged to exercise extreme care with respect to outdoor activities that could cause grass fires. Avoid equipment that can cause sparks near dry grass or brush. Do not toss cigarettes on the ground. Report new fires quickly to the nearest fire department or law enforcement office....EXTREME FIRE DANGER... The Grassland Fire Danger Index will reach the extreme category this afternoon. Extreme weather conditions or a very low moisture content of grasses and other dry organic material on the ground indicate that critical burning conditions exist. A fire will start easily and has the potential to become large and spread quickly becoming erratic with extreme behavioral characteristics. No outdoor burning should take place. OUTLOOK FOR THURSDAY AFTERNOON...The Grassland Fire Danger Index will reach the high category. The grassland fire danger product reflects fire danger for native grasses. It is not intended for cured agricultural crops, nor will it reflect conditions in road ditches which have been mowed. |
