Frost may come early in South Dakota

AMES, I.A.(WNAX)- Continued drought and heat now could be a contributing factor to an early frost.

Dennis Todey, with the Midwest Climate Hub in Ames Iowa, says dry air and soil leads to a quicker cool off at night.

Todey says early dry down of crops could also contribute to the frost risk.

Normal frost dates over the northern plains become a factor in late September into October.
