SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1102 AM CST Thu Dec 17 2020 Valid 181200Z - 191200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Isolated thunderstorms may develop late Friday night across parts of central/east Texas to the ArkLaTex vicinity. Severe thunderstorms are not expected. ...Synopsis and Discussion... An upper trough will move eastward from the Southwest across the southern/central Plains on Friday. Gradual and modest low-level moisture return should occur across parts of central/east TX to the ArkLaTex vicinity through the period. As large-scale ascent preceding the upper trough overspreads this region late Friday night, isolated thunderstorms may develop in a low-level warm/moist advection regime. Weak instability (MUCAPE 500 J/kg or less) is expected to preclude a severe risk, with any convection that does develop likely remaining elevated. ..Gleason.. 12/17/2020
