Subj : DAY2 3/5 RISK AREA POSTED To : All From : Mike Powell Date : Fri Jun 19 2026 07:57:25 ACUS02 KWNS 190548 SWODY2 SPC AC 190547 Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1247 AM CDT Fri Jun 19 2026 Valid 201200Z - 211200Z ....THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS FOR PORTIONS OF THE CENTRAL PLAINS.... ....SUMMARY... Severe thunderstorms are likely across portions of the central Plains vicinity from Saturday afternoon into Saturday evening. Large to very-large hail, severe winds (some 75+ mph), and tornadoes are possible. ....Synopsis... A mid-level ridge will de-amplify as it emerges from the Rockies to the central Plains on Saturday. As this occurs, mid-level flow will strengthen across the Rockies with strong lee cyclogenesis across eastern Colorado. A frontal zone will extend eastward from the surface low somewhere near southern Nebraska with a dryline extending southward into the southern Plains. ....Central Plains... Low-level flow will strengthen across the Plains during the day Saturday as the lee cyclone deepens across eastern Colorado. This will result in northward moisture transport and destabilization across Kansas, northeast Colorado, and southwest Nebraska. By mid-afternoon, expect storms to develop within the upslope flow regime across eastern Wyoming, southwest South Dakota, and the Nebraska Panhandle. Forecast soundings show cool temperatures aloft, steep lapse rates, and strong shear which will support supercells capable of large to very large hail in this area. By later in the afternoon, expect storm development along the uncapped dryline across eastern Colorado and western Kansas, and along the frontal zone in central/southern Nebraska. Moderate mid-level flow across the warm sector within this zone will support a supercell storm mode. These initial supercells will pose a threat for large to very large hail. In addition, some tornado threat will exist with this activity, particularly along the front and as the low-level jet strengthens during the evening. Expect these supercells to congeal into one or more MCSs during the evening and track southeastward into central and eastern Kansas, with an increasing wind threat (with some 75+ mph gust potential), and perhaps a QLCS/embedded supercell tornado threat. ...Bentley.. 06/19/2026 $$ --- SBBSecho 3.28-Linux * Origin: Capitol City Online (618:250/10) .
