Upfront, my 10:1 for tomorrow is 1.8. Kuchera is 3.3".
The 18 z NAM stinks with calling for temperatures 10 degrees colder than witnessed. If this was accurate and continues, the 15:1 for tomorrow would not apply.
15:1 is only good for 25 degrees.
How is it possible for the 3K and 12K NAM to miss surface temperatures 10 degrees in 6 hours????
