SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1043 AM CST Tue Dec 31 2024 Valid 011200Z - 021200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are not expected Wednesday. ...Synopsis... An upper low will be situated over northern Ontario with a broad area of lower heights across the Canadian Prairies. South of this low, a broad fetch of moderate to strong high-level flow will extend from the western US into the Southeast, with a leading wave ejecting in negative-tilt fashion across the Northeast. With time, upper ridging will occur along the West Coast. At the surface, high pressure will be centered over the central to southern Plains, with a deepening low over Maine, in association with the upper wave. As a result, northerly winds will exist along the Gulf Coast, with offshore flow along the East Coast as well. The end result will be stable conditions across the bulk of the CONUS, with little if any thunderstorm or lightning potential. While a flash or two cannot be ruled out ahead of the New England surface low, any weak elevated instability should remain largely offshore. ..Jewell.. 12/31/2024
