URGENT - IMMEDIATE BROADCAST REQUESTED Tornado Watch Number 178 NWS Storm Prediction Center Norman OK 355 PM MDT Sun Apr 27 2025 The NWS Storm Prediction Center has issued a * Tornado Watch for portions of Far Northeast Colorado Western Nebraska Southwest South Dakota * Effective this Sunday afternoon and evening from 355 PM until 1100 PM MDT. * Primary threats include... A couple tornadoes possible Scattered large hail and isolated very large hail events to 3 inches in diameter possible Isolated damaging wind gusts to 70 mph possible SUMMARY...Severe storms including supercells are expected this evening, with very large hail possible as the main and initial hazard. Tornado potential is expected to increase toward/after sunset as additional low-level moistening occurs. Damaging winds are also possible. The tornado watch area is approximately along and 70 statute miles east and west of a line from 85 miles northeast of Chadron NE to 60 miles west southwest of North Platte NE. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU8). PRECAUTIONARY/PREPAREDNESS ACTIONS... REMEMBER...A Tornado Watch means conditions are favorable for tornadoes and severe thunderstorms in and close to the watch area. Persons in these areas should be on the lookout for threatening weather conditions and listen for later statements and possible warnings. && AVIATION...Tornadoes and a few severe thunderstorms with hail surface and aloft to 3 inches. Extreme turbulence and surface wind gusts to 60 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 23030. ...Guyer Read more

MD 0582 CONCERNING SEVERE THUNDERSTORM WATCH 179... FOR NORTHERN HIGH PLAINS
Mesoscale Discussion 0582 NWS Storm Prediction Center Norman OK 0930 PM CDT Sun Apr 27 2025 Areas affected...Northern High Plains Concerning...Severe Thunderstorm Watch 179... Valid 280230Z - 280400Z The severe weather threat for Severe Thunderstorm Watch 179 continues. SUMMARY...Severe threat continues with thunderstorms this evening. DISCUSSION...Low-level convergence is gradually shifting east this evening as the primary surface cyclone is now into northeast CO. Even so, the main boundary currently arcs along the western fringe of ww179 from Carter County MT-western Pennington County SD. Several longer-lived storms with large hail are progressing across southeast MT toward northwest SD, while more liner activity appears to be evolving along the wind shift over the western Black Hills. Hail remains the primary concern with this activity, though the potential for gusty winds with line segments is of some concern. Severe threat continues. ..Darrow.. 04/28/2025 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...ABR...BIS...UNR...BYZ...GGW...

Valid 280147Z - 280245Z The severe weather threat for Tornado Watch 178 continues. SUMMARY...The supercell tornado risk continues across portions of northwest into north-central Nebraska. DISCUSSION...Several long-lived right-moving supercells have merged into a supercell cluster over the last hour over Cherry County Nebraska. The LNX VWP depicts a 50-kt low-level jet overspreading backed surface winds -- yielding a large clockwise-curved hodograph (280 m2/s2 0-500m SRH). This wind profile, combined with rich boundary-layer moisture (lower 60s dewpoints) will continue to support a supercell tornado threat with northeastward extent over at least the next hour. ..Weinman.. 04/28/2025 ...Please see www.spc.noaa.gov for graphic product...

MD 0580 CONCERNING TORNADO WATCH 178... FOR PORTIONS OF WESTERN NEBRASKA
Mesoscale Discussion 0580 NWS Storm Prediction Center Norman OK 0644 PM CDT Sun Apr 27 2025 Areas affected...Portions of western Nebraska Concerning...Tornado Watch 178... Valid 272344Z - 280115Z The severe weather threat for Tornado Watch 178 continues. SUMMARY...Supercell tornado threat is expected to increase over the next hour. DISCUSSION...Recent radar data from LNX has shown splitting supercell structures and related mergers over portions of western NE, with a recent intensification of a right-moving supercell. As this storm and other nearby developing storms continue east-northeastward, a moist boundary layer (dewpoints in the lower 60s) and increasing clockwise-curved hodographs (effective SRH increasing to around 400 m2/s2) will favor an increasing supercell tornado risk. Given, the ample streamwise vorticity and rich low-level moisture, a strong tornado cannot be ruled out. ..Weinman.. 04/27/2025 ...Please see www.spc.noaa.gov for graphic product...

SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0759 PM CDT Sun Apr 27 2025 Valid 280100Z - 281200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FOR PARTS OF THE NORTHERN GREAT PLAINS INTO NE...AND PARTS OF THE SOUTHERN HIGH PLAINS... ...SUMMARY... Isolated to scattered severe thunderstorms are possible this evening into early morning Monday across parts of the Great Plains. Large to very large hail, severe gusts, and a few tornadoes are all possible. ...Northern Great Plains into NE...MN...northern IA... Supercell development is underway this evening across parts of western NE, with other strong to potentially severe storms expected to increase in coverage from southeast MT into western SD. The environment across parts of western NE and vicinity has become favorable for tornadoes this evening, including strong-tornado potential. See MCD 580 for more information. Some threat for hail, severe gusts, and possibly a tornado will also persist through the evening from southeast MT into western SD. Late tonight, some clustering/upscale growth is expected, with at least an isolated threat of hail and strong/damaging gusts eventually spreading into parts of MN and northern IA before the end of the period. ...Central/southern High Plains... Despite a volatile environment (as noted in the 00Z AMA sounding), storms have struggled to initiate near the dryline from western KS into the TX Panhandle. There remains a narrow window of opportunity for storm initiation near the dryline through dusk, though confidence is not high due to generally nebulous large-scale ascent. A Slight Risk has been maintained for the remaining conditional threat this evening across the southern High Plains. Farther south, a cluster of initially high-based convection earlier intensified near/east of Lubbock. If convection in this area can become surface-based, then a couple of supercells could evolve with all severe hazards possible. However, recent trends suggest this activity may continue to weaken with time. ...Central MS vicinity... A couple stronger storms persist this evening across central MS, within a moderately unstable and modestly sheared environment. A general weakening trend is expected to continue with time, though some localized threat for hail or damaging gusts may continue for part of the evening. ..Dean.. 04/28/2025 Read more
