SPC 1930Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0228 PM CDT Wed Apr 30 2025 Valid 021200Z - 031200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FROM THE LOWER GREAT LAKES REGION SOUTHWESTWARD TO TEXAS... ...SUMMARY... Scattered thunderstorms are expected from the Northeast, across the Ohio, Tennessee, and Lower Mississippi Valleys and into Texas. Isolated storms within this zone will likely become capable of producing damaging wind gusts and hail. ...Synopsis... An upper trough initially over the north-central U.S. is forecast to dig/expand southeastward, evolving into a sharp/short-wavelength feature extending from the Great Lakes to the southern Plains by the end of the period. Meanwhile, as a second/sharp trough approaches the West Coast late, the overall pattern over the U.S. will become highly amplified and progressive into the weekend. At the surface, a cold front extending initially from the Great Lakes to Texas will advance steadily eastward. By early Saturday morning, the boundary should extend from New England southwestward to the Lower Mississippi/western Gulf Coast region. ...Lower Great Lakes to the southern Plains... Showers and thunderstorms are forecast to be ongoing across portions of the central and eastern U.S., near and ahead of the aforementioned cold front. The ongoing clouds and precipitation will likely hinder heating/destabilization across parts of the region -- particularly from the Kentucky area northeastward. This, combined with modest shear suggests only isolated stronger storms, but risk appears sufficient to introduce marginal risk ahead of the front, as far north as the Lower Great Lakes. From roughly the Tennessee Valley westward into Texas, a more unstable airmass is expected to evolve, given more substantial low-level moisture, and potentially greater heating. However, widespread convection may be ongoing across the Arkansas area westward to the Texas Panhandle/South Plains region near and just north of the surface front. Evolution of this convection, and progression of associated outflows into the warm sector, will likely influence location, and organization, of subsequent storms through the day Friday. Thus, will maintain/expand MRGL risk across a broader area extending into the Tennessee Valley, with further refinement of the area likely in later outlooks. ..Goss.. 04/30/2025 Read more
