...Cold with Areas of Frost or a Freeze This Morning...
Light winds and a period of clear skies may lead to areas of
frost or even a freeze for parts of eastern Iowa and northwestern
Illinois. The most likely area for lows at or below freezing are
roughly along and north of a line from Princeton, Illinois to
Independence, Iowa. To the south of this line, lows will average
in the low to mid 30s and the frost will not be as widespread.
Locations that maintain cloud cover through the night will have
steady temperatures in the upper 30s, resulting in little if any
frost.
