SPC Nov 24, 2021 0600 UTC Day 1 Convective Outlook

SPC 1200Z Day 1 Outlook Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1134 PM CST Tue Nov 23 2021 Valid 241200Z - 251200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Non-severe thunderstorms are possible this evening into tonight from parts of the southern Plains into the mid Mississippi Valley. ...DISCUSSION... An upper-level trough will move across the north-central U.S. today. Southwest flow at mid-levels will remain across much of the south-central U.S. Low-level moisture advection in the southern Plains will gradually increase surface dewpoints into the lower to mid 60s F across much of southern and east-central Texas. This will contribute to weak destabilization by late afternoon ahead of a cold front moving southeastward across the central Plains and southern High Plains. Thunderstorm development will become possible along the axis of a strengthening low-level jet early this evening from central Texas north-northeastward into eastern Oklahoma. The potential for thunder will increase later during evening and into the overnight period. Thunderstorms will become possible east-northeastward across parts of the Ozarks and into the mid Mississippi Valley along the axis of the low-level jet. Much of this activity will remain elevated. Instability is expected to be too weak from the southern Plains into the mid Mississippi Valley for a severe threat. ..Broyles/Jirak.. 11/24/2021 Read more LIVE: spc.noaa.gov
