Day 4-8 Outlook
Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0306 AM CST Fri Dec 11 2020 Valid 141200Z - 191200Z ...DISCUSSION... Within a belt of westerlies emanating from the mid-latitude Pacific, it appears that another significant short wave trough will progress inland of the Pacific coast by early Monday, before traversing the remainder of the nation by the middle to latter portion of next week. While it appears that this feature could support significant surface cyclogenesis near or east of the Atlantic Seaboard late next week, medium-range guidance continues to suggest that any surface cyclogenesis over the interior U.S., east of the Rockies, will remain modest to weak. A substantive inland return flow of moisture off the Gulf of Mexico appears unlikely, contributing to the maintenance of generally stable conditions and low convective potential.
