Well, let's see. The official high was 72. In typical fashion for the high
in these situations there, the GFS was 3 too cool. However, the GFS is typically way too warm on promising very radiational cooling nights like tonight. Moreover, it currently has the dewpoint 10 too high.
On two occasions during the mid March very cold shot with a similarly good radiation setup, it dropped 32 from the prior day's high. A few days later, it dropped a whopping 39. Nights are a bit shorter than a few weeks ago but that shouldn't be a big factor. The current dew point is way down at 26. The cold high center won't quite get down that far but the center will be down into AL allowing for very light winds late along with clear skies and early morning very low dewpoints that will likely not be any warmer than 32. With the three coldest lows for 4/8 being 34-35, I'm going to go further out on the limb than you with a drop of 37 to 35. The 12Z hrs has a low only down to 48! Gainesville is going to show off tonight and show who is King of Deep South US radiational cooling.
