SPC Jan 30, 2025 1930 UTC Day 3 Severe Thunderstorm Outlook
SPC 1930Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0106 PM CST Thu Jan 30 2025 Valid 011200Z - 021200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorm potential across the United States appears low on Saturday. ...Synopsis... A low-amplitude, mostly zonal upper flow regime will emerge across the CONUS on Saturday. A baroclinic zone will weaken, while a surface front dissipates over the western Atlantic and FL Peninsula. A few showers are possible over the FL Peninsula, especially near the east coast as this occurs, but thunderstorm activity should be limited due to poor thermodynamics, and weakening ascent and vertical shear. Moist, onshore flow will stream over the Pacific Northwest and northern Rockies as a surface cold front develops east across the region. Showers/low-topped convection with a couple of lightning flashes may occur near coastal WA/OR into the northern Rockies given cold midlevel temperatures and steep lapse rates. However, coverage is expected to be less than 10 percent. ..Leitman.. 01/30/2025 Read more
