HIGHEST SFC-3 KM STORM RELATIVE HELICITY WILL RANGE FROM 250 M^2/S^2
NEAR THE COAST TO 400 M^2/S^2 NORTH OF HIGHWAY 84. A SWEAT INDEX
AROUND 360 SUGGEST THAT TORNADIC SUPERCELLS ARE POSSIBLE. HOWEVER
THE 500-300 MB LAPSE RATES ARE NOW DOWN TO 6.5 C/KM...MLCAPES DOWN
TO 250 J/KG SOUTHERN ZONES TO 450 J/KG NORTHERN ZONES...K INDICES
FROM 30 TO 35...AND LIFTED INDEX OF ONLY -2 SUGGEST ONLY MARGINAL
INSTABILITY WITH MODERATE CONVECTION. ENVIRONMENTAL SHEAR WILL FAR
OUT WAY THE INSTABILITY (CAPE)...AND BRN INDICES NOW BELOW 8 CONFIRM
THIS. SO THIS IS NOT THE BALANCE BETWEEN CAPE AND SHEAR THAT WE
WOULD BE LOOKING FOR IF WE WERE EXPECTING STRONG TORNADOES
