Recent weather has been unusually cool for this time of year and crops are a little bit behind according to the Iowa Crop Progress report.
The weather looks to round up a bit warmer next week, but the signs of fall approaching are clear according to State Climatologist Harry Hillaker. There's about a month till the first average freeze in north Iowa and October 6th is the average first freeze of central Iowa.
He says, "It's down to 40 degrees in Sheldon and Spencer, which is only 8 degrees above freezing so certainly a sign that Fall's on the way. It seems everyone's been commenting on how pleasant the weather's been and it has been quite a change in the heat and humidity and in this time in August, normal highs are about 80-81 degrees, normal lows about 60. So, we're already down about 6 or 7 degrees for a typical mid summer heat."
