Checked NUCAPS sounding at 19Z just east of LBF and used T/Td of 89/66 to modify the surface and got around 4000 J/kg CAPE.  Initially NUCAPS near the surface was much too cool and dry (80/54), so the modification was necessary.   It did agree better with the SPC mesoanalysis and RAP which showed values over 3000 J/kg and much better than the LAP CAPE.  MrSnow/BT
