soil tempature

Is there a university website that updates the current soil temp throughout the ohio-ind region. Once the calendar hits April the phone will go crazy saying WE ARE TOO LATE to apply crabgrass control. I know I can use my own soil gauge. However, I would like to direct the homeowner to a University site so they know the temp is still colder thaen they think----Thanks

I believe here in Iowa the 3t manual states that crabgrass control needs to be applied before soil temps are above 65 degrees. Does that sound about right?
When the forsythia starts to bloom, that's the same time for the first crabgrass seed to grminate.
so the preventer needs to be put before that.

Back before I did lawn care and I did weed and feed on my yard. I always started with crabgrass preventor in may and it always seemed to work.

I've also that red bud trees are a better reference then forsythia. Forsythia blooms according to air temputeres and red rud to soil temputers.
