SPC 1630Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1013 AM CST Sun Dec 08 2024 Valid 081630Z - 091200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not expected through tonight. ...Lower MS Valley... A weak upper low is tracking northeastward across the TX Panhandle today, with the subtropical mid-level jet extending from northern Mexico into the lower MS Valley. Broad large-scale ascent has resulted in periodic episodes of thunderstorms across TX overnight and this morning. This regime is expected to shift eastward today into more of AR/LA and eventually the TN Valley overnight. Low-level and deep-layer vertical shear is very strong, and there is a low probability of a strong storm or two across northeast LA into western/central MS late this afternoon capable of gusty winds. However, thermodynamics are quite weak and the overall severe threat appears too low to introduce probabilities. ..Hart/Squitieri.. 12/08/2024
