New model guidance
"Model data from the evening computations appear to all be in, and the model guidance (not the actual forecast) from the NGM model gives us a low temperature tomorrow night of 31 degrees with an 88% probability of precipitation (PoP). Thursday's high is put at 37o, with 98% PoP, and for Thursday night those figures are 36o/80%.The GFS output is even jucier. For Nashville, the GFS guidance gives us a Wednesday night low of 25o and a 72% PoP. Thursday's values are 39o/99%, and for Thursday night it's 30o/82%."
You can lower these temperatures by a few degrees for those of us here in the Upper Cumberland Area. I'm thinking 27 on Wednesday night and Thursday morning......
We'll update again later.....
