SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1128 AM CST Fri Dec 04 2020 Valid 051200Z - 061200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not expected Saturday or Saturday night. ...Synopsis/Discussion... An amplified large-scale pattern will persist over the CONUS with split upper-level flow over the Plains and Midwest. Thunderstorm potential along the Eastern Seaboard will have largely diminished into Saturday in the wake of a cold frontal passage. Most of the thunderstorm potential will be focused ahead of the cold front over the western Atlantic, but a few near-shore thunderstorms could occur in association with weak elevated buoyancy and cyclogenesis near the New England coast. Elsewhere, ahead of an eastward-moving southern-stream trough over northeast Mexico and central/southern Texas, sufficient elevated buoyancy may allow for a few thunderstorms near the Texas coast, although the bulk of the deeper convection should remain decidedly offshore. Finally, low-topped convection may accompany a shortwave trough approaching the coastal Pacific Northwest Saturday afternoon into Saturday night. However, forecast thermodynamic profiles do not appear overly supportive of lightning flashes. ..Guyer.. 12/04/2020
