Analysis

During arrival, the aircrew (visually & by use of wx radar) noted thunderstorms (tstms) west & southwest of the arpt. The crew elected to continue & make an ILS apch. At 1636, a spcl wx obsn had tstm info, but was not noted. At 1650, the vis dropped to 1/4 mi with hvy rain & hail. As the acft apchd rwy 21R, a vip lvl 4 tstm moved from west to east over thenorthern part of the arpt. The contoller provided wind info from the low lvl wind shear alert sys (llwas), but used improper phraseology & failed to provide RVR info when the vis went blo 1 mi. The crew had difficulty in understanding the llwas info due to the amount & rapidity that it was provided. At aprx 350' AGL, the acft encountered low clds, hvy rain, hail & turbc. The aircrew initiated a missed apch. The speed increased to 143 KTS, then decreased to aprx 119 KTS.the capt believed the acft would not climb & elected to land. The acft touched down about 2500' down the rwy with the gear partially extended, then slid 3800' & went off the rwy. The wind was gusting to 32 KTS.
