SPC Nov 23, 2021 1630 UTC Day 1 Convective Outlook

SPC 1630Z Day 1 Outlook Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1030 AM CST Tue Nov 23 2021 Valid 231630Z - 241200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not expected today or tonight. ...Synopsis/Discussion... A progressive but amplified large-scale pattern will continue, highlighted by an amplifying upper trough over the Great Basin/Rockies and an eastward-building upper ridge over the Midwest and Great Lakes. The general prevalence of dry/stable conditions will likely preclude thunderstorms across the CONUS. One potential exception for a couple of lightning flashes might be tonight across southern/eastern Arizona and the Four Corners area, although thermodynamic profiles will be quite marginal and thunderstorm probabilities are expected to remain very low (below 10 percent). ..Guyer.. 11/23/2021 Read more LIVE:
