SIOUX FALLS, S.D. (KELO AM) - Friday morning the dew point, the measure of moisture in the air, will drop to the low 30’s in Sioux Falls.
Forecaster Brad Adams says the drop in humidity will precede temperatures in low 30’s tomorrow night setting the stage for a possible frost or freeze warning.
Adams says it's still too early to commit to such watches or warnings but he says if you want to extend the life of your flower or vegetable gardens you'll want to cover them.
Adams says warmer, moister air moves in later next week.
