** DEFINITIONS ** [CPR] = Combined probability (Prob_Field_1 x Prob_Field_2 x ... x Prob_Field_N) [MAX] = Maximum from any member at each grid point [MD] = Median [MDXN] = Median value contoured. The dashed red line is the union of all members at the lowest contour value plotted (i.e., where at least one of the 16 members exceeds the value of the first median contour). The dashed blue line is the intersection of all members at the lowest contour value plotted (i.e., where all 16 members exceed the value value of the first median contour). [MIN] = Minimum from any member at each grid point [MN] = Mean [MNSD] = Mean and Standard Deviation [PM] = Probability Matched Mean Value [PR] = Probability (percentage of members meeting/exceeding some condition) [SP] = Spaghetti ** SPECIFIC INFORMATION ON AVAILABLE FIELDS ** [MAX]:10m_Wind ->Maximum 10 meter wind (mph) at each grid point [MAX]:2m_DewPoint ->Maximum 2 meter dew point (degF) at each grid point [MAX]:2m_Temperature ->Maximum 2 meter temp (degF) at each grid point [MAX]:Fosberg_Index ->Maximum Fosberg Index value at each grid point [MDXN]:2m_DewPoint ->Median 2 meter dew point (contours start at 40 degF) with union (dashed red) and intersection (dashed blue) at 40 degF.

Links to official SPC operational products are found at the bottom of every menu. Many of the SREF products were developed for testing the utility of SREF analysis in the prediction of SPC mission critical items, including: thunderstorms and severe thunderstorms, large scale critical fire weather conditions, and mesoscale areas of hazardous winter weather. In order to accomplish this goal and test new and unqiue methods of SREF application in an operational environment, many fields not produced in the NCEP postprocessor were calculated locally for SPC purposes.
