Dawn brought clear skies and cold temperatures just above zero. It was still only in the single digits by about mid morning. Late this morning there were varying amounts of clouds but we were into the middle 20s. Early this afternoon it was in the upper 20s with the sun back to being fully out. Barely but it got above freezing today.
