SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0740 PM CDT Sat Oct 17 2020 Valid 180100Z - 181200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not expected across the contiguous United States tonight. ...AR Region... No changes are warranted to the 20z outlook. Although no changes to thunderstorm probabilities are forecast, 00z soundings from FWD and LZK are a bit dryer than earlier NAM suggested. 850mb had yet to saturate at LZK and 1km RH was also lower at FWD than 12z models suggested. While moisture return is somewhat retarded across this region, strengthening LLJ from Northeast TX into AR later this evening should contribute to moistening/buoyancy such that elevated convection should develop. Instability will likely be inadequate for any meaningful threat for severe hail. ..Darrow.. 10/18/2020
