as tenths of a microbar per second at 700 hPa, with positive values indicating upward motion; ACCUM (accumulated precipitation, past 3h) is given as hundredths of a millimeter; RH1, RH2, and RH3 are the % RH at the surface, 1000', and 3000', respectively; T1, T2, and T3 are the temperatures at 500', 1000', and 1500', respectively. Gust is estimated according to the NCEP HRRR gust algorithm.
