More complete discussion of the parameters and how they are calculated will come in future releases. For now, here is a listing of the parameter names for reference.
You do not need to review the details of this page unless you have a particular question about a parameter.

SB PARCEL - surface-based parcel
FCST PARCEL - forecast parcel
MU PARCEL - most unstable parcel
- CAPE - Convective Available Potential Energy of the latest lifted parcel (J/kg)
- CINH - convective inhibition (J/kg) for the latest lifted parcel to reach the LFC
- LCL - lifted condensation level for the latest lifted parcel, pressure (mb), ht AGL (ft)
- LFC - level of free convection for the latest lifted parcel, pressure (mb), ht AGL (ft)
- PW - precipitable water (in)
- total amount of condensed water within the lowest 400mb
- WBZ - Wet Bulb Zero (ft)
- BRN - Bulk Richardson Number
- ConvT - convective temperature (F)
- lowest surface temperature with < 5 J/kg convective inhibition, using the 100mb mean parcel mixing ratio to account for afternoon mixing
- FGZ - freezing level (ft)
- height of the 0C isotherm in ft AGL
- BRN Shear - Bulk Richardson Number (BRN) Shear (m2/s2)
- bulk shear term in the denominator of the BRN
- square of the shear between 0-500m AGL mean pressure-weighted wind and 5500-6000m AGL mean pressure-weighted wind
- Bunkers Right - right mover supercell motion vector (deg/kt)
- 0-1km Helicity - 0-1km storm-relative helicity (m2/s2)
- 0-3km Helicity- 0-3km storm-relative helicity (m2/s2)
