ZCZC SPCSWOD48 ALL ACUS48 KWNS 180848 SPC AC 180848 Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0348 AM CDT Fri Sep 18 2020 Valid 211200Z - 261200Z ...DISCUSSION... Deterministic medium-range guidance generally suggests that a tropical cyclone over the western Gulf of Mexico should move slowly along/near the TX Coast from Day 4/Monday through the middle of next week, although predictability remains low at this extended time frame. Refer to the latest forecasts from the National Hurricane Center regarding the track and intensity of this system. At this point, the potential for even weak destabilization to occur inland is highly uncertain. Accordingly, the severe potential associated with this tropical cyclone appears fairly low at this time, but some chance cannot be ruled out along parts of the TX Coast into the Southeast from Day 5/Tuesday onward. Otherwise, surface high pressure is forecast to remain over much of the eastern CONUS next week. This anticyclone, coupled with the tropical system over the western Gulf of Mexico, is expected to limit substantial low-level moisture return for most of the CONUS away from the Gulf Coast, along with appreciable severe potential. ..Gleason.. 09/18/2020 CLICK TO GET WUUS48 PTSD48 PRODUCT
