The sprayer is out today (14Dec2015) making an application for those spots you see in the picture just in front of the boom.
It was in the upper 50's to low 60's this morning with the dew point about the same. Anytime the dew points are able to reach that level for a few nights in a row, dollar spot will occur in this region.
I still believe winter will be here in the next couple of weeks but get out and enjoy this weather while you can. Maybe it's an early Christmas present!
