Very high fire danger today for field fires, for areas along and south of Highway 30. These areas have the best conditions for cropland fires growing rapidly. For the Stateline, this includes Whiteside County, while the rest of the area has more of a limited fire risk.
This happens as the relative humidity drops to about 30-35%, which essentially is a very dry air mass. We combine this with strong westerly winds that will increase and become sustained from 5-15mph to then 15-25 mph, and then gusting to 35 mph. With these combined conditions and now harvested fields it will make for a high fire danger. If an agricultural field were to catch fire, the weather conditions would support it spreading quickly.
