SPC Oct 11, 2018 Day 4-8 Severe Weather Outlook
Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0233 AM CDT Thu Oct 11 2018 Valid 141200Z - 191200Z ...DISCUSSION... Medium-range model guidance continues to suggest a strong surface anticyclone will build south across the Rockies/High Plains forcing a sharp cold front deep into TX during the day Sunday. This boundary will undercut a seasonally moist air mass which should result in a corridor of elevated post-frontal convection across the southern Plains into the lower MS Valley. While some of this elevated convection could be strong immediately behind the front, large-scale pattern does not favor organized severe, especially if thunderstorms are primarily post frontal in nature. Continental air mass is expected to spread into lower latitudes which will shunt higher PW environment/convective threat off the Gulf Coast early next week.
