Enhanced IR Step 8
Final T Number Constraints:

1. Initial Classification must be 1.0 or 1.5 (PERIOD!)

2. During the first 48 hours of development Final-T can not be lowered at night (but you can during day-light).		 3.  24 hours after initial 1.0, Final-T must be < 2.5.

4. Final-T must be +/- 1.0 from MET.		 5. Final-T limits:
  • < 3.5 =FT can change only 0.5 per 6 hours.
  • > 4.0 = FT can change only 1.0 per 6 hours, 1.5 per 12 hours, 2.0 per 18 hours, or 2.5 per 24 hours.
