516 ACUS02 KWNS 020610 SWODY2 SPC AC 020609 Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 0109 AM CDT Tue Jul 02 2024 Valid 031200Z - 041200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS THE MIDWEST/OHIO VALLEY AND CENTRAL PLAINS... ...SUMMARY... Severe thunderstorms are expected on Wednesday, particularly across parts of the Midwest/Ohio Valley and central Plains. ...Midwest/Ozarks/Ohio Valley... Moderate to strong destabilization is expected within a moist air mass preceding an east/southeastward-moving cold front, which is likely to be effectively augmented by early day convection and residual cloud cover. As a shortwave trough transitions northeastward over the Great Lakes toward Ontario, at least weak height falls and moderately strong mid-level westerlies will generally influence areas as far south as the Ohio River and parts of the Ozark Plateau. Intensifying multicells/banded clusters are probable into Wednesday afternoon, with bouts of wind damage as the primary hazard through evening. ...High Plains/Central Plains... Height falls and a strengthening of cyclonically curved westerlies are expected ahead (east-southeast) of an amplifying mid/upper-level trough over the northern Rockies and northern High Plains. By mid/late-afternoon Wednesday, potentially severe storms capable of hail/strong wind gusts will be possible within a broad north/south corridor from the western Dakotas and southeast Montana/northeast Wyoming southward into eastern Colorado, northeast New Mexico, and Texas/Oklahoma Panhandles. Some tornado risk may also exist near the north/south-oriented surface trough across the central High Plains including western Nebraska/eastern Colorado/northwest Kansas, where deep-layer/low-level shear will be stronger and more favorable for initial supercells. The most focused area of potentially severe storms, including possible evening-time MCS development, may evolve from western Nebraska/northeast Colorado into western/northern Kansas and southern Nebraska. ..Guyer.. 07/02/2024 $$
