MD 0864 CONCERNING SEVERE POTENTIAL...WATCH LIKELY FOR SOUTHERN NEBRASKA...NORTH-CENTRAL KANSAS
Mesoscale Discussion 0864 NWS Storm Prediction Center Norman OK 0539 PM CDT Sun May 18 2025 Areas affected...Southern Nebraska...North-central Kansas Concerning...Severe potential...Watch likely Valid 182239Z - 190115Z Probability of Watch Issuance...80 percent SUMMARY...A severe threat will likely continue across north-central Kansas, and expected to develop across parts of southern Nebraska. Supercells with large to very large hail, wind damage and an isolated tornado threat will be possible. Weather watch issuance appears likely. DISCUSSION...Over the last hour, convection has increased in coverage across north-central Kansas. The storms are located along the eastern edge of a moderately unstable airmass, where surface dewpoints are in the lower 60s F. The storms appears to be related to a band of large-scale ascent that is moving northeastward across the central Plains, evident on water vapor imagery. The North-Platte 20Z sounding shows a cap in place, and RAP forecast soundings suggest the cap extends further to the southeast into north-central Kansas. For this reason, the ongoing convection appears to be elevated. Effective shear of 50 to 60 knots and 700-500 mb lapse rates near 8 C/km will be favorable for supercells with large hail. Hailstones greater than 2 inches in diameter will be possible. In addition, an isolated wind-damage/tornado threat will also be possible. Although this potential will increase later this evening as a second round of storms move into the area. ..Broyles.. 05/18/2025 ...Please see www.spc.noaa.gov for graphic product...

SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0800 PM CDT Sun May 18 2025 Valid 190100Z - 191200Z ...THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS OF THE CENTRAL PLAINS... ...SUMMARY... Severe thunderstorms capable of all severe hazards remain possible this evening across portions of the central and southern Plains. Several strong to intense tornadoes are possible. ...01z Update... 500mb speed max is translating across northeast NM into southwest KS early this evening. Left-exit region of this feature appears largely supportive of an extensive corridor of strong/severe thunderstorms across the central High Plains from northwest KS into western NE. Over the last hour or so, multiple storm mergers have evolved into more of a north-south band of convection from Sheridan County NE-north of GLD. This developing MCS should propagate east over the next several hours with an attendant risk for hail, wind, and perhaps a few tornadoes -- especially with embedded supercells. Farther southeast, roughly a half dozen isolated supercells arc from Sheridan County KS to Woods County OK. 1km VAD winds are quite strong across northern OK into central KS with 50kt common. 0-3km SRH at VNX/DDC/ICT exhibit more than 500 m2/s2. As LLJ is expected to remain focused into this portion of the plains it seems reasonable that ongoing supercells should remain organized as they track northeast, albeit into a less unstable air mass due to earlier convection. Tornado threat remains highest across this corridor until updrafts begin to decouple from the boundary layer. Southwest-northeast corridor of strong/severe thunderstorms is expected to linger across much of west-central into north-central TX this evening as adequate 500mb flow remains supportive of organized updrafts. ..Darrow.. 05/19/2025 Read more
