SPC 1630Z Day 1 Outlook Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1007 AM CST Fri Dec 03 2021 Valid 031630Z - 041200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Isolated thunderstorms may develop this afternoon through overnight across parts of the southern Plains to Mid-South. ...Southern Plains to Mid-South... Morning water vapor loop shows a well-defined shortwave trough moving across TX. A large shield of low and mid clouds is associated with the area of large-scale lift ahead of the trough. Observed and forecast soundings across this area show a pronounced capping inversion, limiting surface-based parcels from convecting. However, considerable moisture is noted above the inversion, which has led to marginal elevated CAPE and occasional clusters of lightning flashes this morning. This scenario will likely persist through the forecast period, with showers and sporadic thunderstorm activity possible from central TX into portions of OK/AR/LA/MS. Coverage of flashes will be quite limited. ..Hart.. 12/03/2021 Read more LIVE:
