Southeasterly winds this afternoon into evening along and west of the Missouri River (15-25 miles per hour sustained, gusts up to 25- 35 miles per hour) lead to High Grassland Fire Danger this afternoon. East of the Missouri River, winds are expected to be a bit lighter, keeping Grassland Fire Danger at Low to Moderate levels. Minimum afternoon humidity is expected to be between 40 and 50 percent across the forecast area today. Overnight tonight into early Monday morning there are some chances for rain showers to weak thunderstorms. Cloud to ground lightning and heavy rain are the only anticipated hazards. The area of highest rainfall is currently expected to be through the US-212 corridor. Expect rain to be out of the area by Monday afternoon. A cold front will then pass through the forecast area Monday afternoon into Monday evening. Behind the front, winds turn northwesterly and increase. The strongest winds are once again expected along and west of the Missouri River, where gusts will reach up to 35 to 45 miles per hour. Afternoon humidity in that area will bottom out around 30 percent. The wind and low humidity combination leads to Grassland Fire Danger Index reaching the Very High category west of the Missouri River, and High for counties bordering the eastern shore of the River (in addition to Lyman County). Moving eastward, wind speeds drop off and humidity increases, limiting fire weather concerns beyond the previously described area.
