Forecasted precipitation totals are verified against actual station observations, by comparing each available station to the amount from the closest model grid point (no interpolation is done). The equitable threat score is calculated for the entire set of observations at each forecast time and at various thresholds.

All other forecast variables are verified against the appropriate Eta model analyses, interpolated to the real-time MM5 grids. We calculate root-mean-square (RMS) error, bias, and the S1 skill score, all field-averaged to generate a single value for each forecast time.

Precipitation:	Time Series	Domain 1 Avg	Domain 2 Avg
Surface Temperature:	Time Series	Domain 1 Avg	Domain 2 Avg
Sigma Level 19 Temperature (mid-troposphere, roughly 500 mb):	Time Series	Domain 1 Avg	Domain 2 Avg
Surface Mixing Ratio:	Time Series	Domain 1 Avg	Domain 2 Avg
Surface U-Comp Wind:	Time Series	Domain 1 Avg	Domain 2 Avg
Surface V-Comp Wind:	Time Series	Domain 1 Avg	Domain 2 Avg
Sea Level Pressure:	Time Series	Domain 1 Avg	Domain 2 Avg

Note: All "surface" values are actually the values at the lowest model level, roughly 30 m above the surface.
