SPC 0700Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1207 AM CST Fri Nov 29 2024 Valid 301200Z - 011200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorm potential appears low on Saturday. ...Synopsis... A broad upper trough will encompass the eastern half of the CONUS, while an upper ridge remains centered along the Pacific coast on Saturday. A couple of embedded shortwave impulses within the upper trough will migrate across the Northeast and Great Lakes vicinity. Cold temperatures aloft will support very minor instability (less than 100 J/kg MUCAPE) across the relatively warmer Great Lakes waters. A lightning flash or two may occur within localized lake effect snow bands near the eastern shores of Lake Erie and/or Lake Ontario. Otherwise, a dearth of boundary layer moisture and stable surface high pressure will preclude thunderstorm activity across the Lower 48 on Saturday. ..Leitman.. 11/29/2024
