Severe Storms

SPC 1200Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1252 AM CDT Fri May 24 2024 Valid 241200Z - 251200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS IN PARTS OF THE MIDWEST TO THE MID-SOUTH AND SOUTHERN GREAT PLAINS... ...SUMMARY... Scattered severe thunderstorms will be possible from parts of the Midwest to the Mid-South and southern Great Plains, mainly this afternoon and evening. Greatest potential for a few tornadoes exists across central to northern Illinois, far eastern Iowa, and southern Wisconsin. ...Upper MS Valley to the Mid-South and southern Great Plains... An MCS will be ongoing at 12Z, likely approaching the Upper MS Valley. 00Z CAM guidance runs the gamut on the evolution of this MCS through late morning into midday. Some suggest it will weaken as it outpaces the instability axis lagging to its southwest over the Lower MO Valley to the southern Great Plains. Others indicate that the southern flank of the MCS may intensify across the Mid-MS Valley into IL, as diurnal destabilization ensues along the instability gradient. Thus, large-scale outflow boundary placement varies considerably by afternoon from far southern WI to far southern MO. The surface cyclone over southeast ND will curl north-northeast into southeast MB and occlude, as it becomes vertically stacked beneath its attendant mid-level low. Daytime mid-level height falls, coincident with stronger low-level shear, will be most pronounced over the Upper MS Valley. These will be weaker with southward extent over the Mid-MS Valley. A predominately zonal mid-level flow regime is expected farther south with minimal height change. However, low-level convergence should be adequate for isolated to scattered thunderstorm development along the trailing cold front from the Upper MS Valley to eastern OK and the dryline into central TX. While the more favorable low-level shear and ascent will be focused north, aforementioned uncertainties over the degree of destabilization related to the evolution of the morning MCS preclude a greater categorical risk. Conditionally, the remnant outflow boundary will likely provide a focus for greater supercell tornado potential. Primary change this outlook is to expand both the 2 percent tornado probability north in WI and the 5 percent prob south in IL. Very large buoyancy is expected from the Ozark Plateau southward with MLCAPE of 3500-4500 J/kg. Despite the lack of appreciable large-scale ascent beyond the front/dryline, this degree of instability, coupled with pronounced mid to upper-level speed shear, should favor potential for very large hail with initial supercell development. Given the frontal forcing, a few clusters may evolve downstream during the evening across parts of the Mid-South to central TX with a mixed large-hail and damaging-wind threat. ...GA to the Carolinas... A parade of MCVs moving eastward across the southern states will aid in isolated-scattered afternoon to early evening thunderstorms. While instability will not be as large as farther west over the Mid-South to southern Great Plains, it will be sufficient to warrant sporadic occurrences of severe hail and damaging winds eastward to the coastal Carolinas. ..Grams.. 05/24/2024 Read more

MD 0921 CONCERNING SEVERE THUNDERSTORM WATCH 294...297... FOR CENTRAL AND EASTERN NEBRASKA...FAR NORTHERN KANSAS...WESTERN IOWA
Mesoscale Discussion 0921 NWS Storm Prediction Center Norman OK 1038 PM CDT Thu May 23 2024 Areas affected...Central and Eastern Nebraska...Far Northern Kansas...Western Iowa Concerning...Severe Thunderstorm Watch 294...297... Valid 240338Z - 240545Z The severe weather threat for Severe Thunderstorm Watch 294, 297 continues. SUMMARY...The wind-damage threat will likely increase as a linear MCS organizes across central and eastern Nebraska over the next couple of hours. The severe threat should eventually affect parts of western Iowa, where additional watch issuance may be needed during the overnight period. DISCUSSION...Mosaic radar imagery currently shows a developing line of strong to severe thunderstorms from far northwest Kansas into central and northeast Nebraska. This line is forecast to begin to accelerate eastward across central and eastern Nebraska over the next couple of hours, as a strengthening low-level jet increases moisture and instability across the central Plains. As the storms move eastward along a west-northwest to east-southeast gradient of moderate to strong instability, the MCS is expected to become increasingly organized. A wind-damage threat will be possible with the stronger parts of the line, and this threat should become more widespread as a large-scale bowing line segment organizes. The wind-damage threat will affect much of eastern Nebraska late this evening, and may affect western Iowa well after midnight. ..Broyles.. 05/24/2024 ...Please see www.spc.noaa.gov for graphic product...

MD 0920 CONCERNING SEVERE POTENTIAL...WATCH POSSIBLE FOR SOUTHEASTERN OKLAHOMA AND NORTH CENTRAL TEXAS NEAR THE RED RIVER
Mesoscale Discussion 0920 NWS Storm Prediction Center Norman OK 0935 PM CDT Thu May 23 2024 Areas affected...Southeastern Oklahoma and north central Texas near the Red River Concerning...Severe potential...Watch possible Valid 240235Z - 240400Z Probability of Watch Issuance...40 percent SUMMARY...Scattered thunderstorms are expected to develop across portions of north central TX and far southern/southeastern OK near the Red River through late tonight. DISCUSSION...Recent radar imagery shows an area of ascent slowly lifting northeastward out of north central TX. This ascent is located near the nose of deeper theta-e advection via a LLJ, on the southern fringe of a residual cold pool, and is likely associated with isentropic ascent. RAP forecast soundings over the next few hours suggest the developing convective environment will support storm organization, with effective shear around 50 kt. These thunderstorms should remain relatively elevated, rooted around 850 mb or so, and MUCAPE is expected to be around 3500 J/kg. Isolated large hail up to 1.50-2.50" in diameter may accompany any of the more discrete updrafts that manage to develop through late tonight. Convective trends will be monitored for a possible watch. ..Barnes/Thompson.. 05/24/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...SHV...TSA...FWD...OUN...

WW 294 SEVERE TSTM ND NE SD 232025Z - 240400Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 294 NWS Storm Prediction Center Norman OK 325 PM CDT Thu May 23 2024 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Southeast North Dakota Central Nebraska Central and Eastern South Dakota * Effective this Thursday afternoon and evening from 325 PM until 1100 PM CDT. * Primary threats include... Scattered damaging wind gusts to 70 mph likely Scattered large hail and isolated very large hail events to 2.5 inches in diameter possible A tornado or two possible SUMMARY...Thunderstorms will increase in coverage through the afternoon across the watch area. Very large hail and damaging winds will be possible in the stronger cells. The severe thunderstorm watch area is approximately along and 55 statute miles east and west of a line from 60 miles north northeast of Aberdeen SD to 40 miles southwest of North Platte NE. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU4). PRECAUTIONARY/PREPAREDNESS ACTIONS... REMEMBER...A Severe Thunderstorm Watch means conditions are favorable for 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. Severe thunderstorms can and occasionally do produce tornadoes. && OTHER WATCH INFORMATION...CONTINUE...WW 292...WW 293... AVIATION...A few severe thunderstorms with hail surface and aloft to 2.5 inches. Extreme turbulence and surface wind gusts to 60 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 25030. ...Hart Read more

MD 0919 CONCERNING SEVERE THUNDERSTORM WATCH 294... FOR NEBRASKA
Mesoscale Discussion 0919 NWS Storm Prediction Center Norman OK 0820 PM CDT Thu May 23 2024 Areas affected...Nebraska Concerning...Severe Thunderstorm Watch 294... Valid 240120Z - 240315Z The severe weather threat for Severe Thunderstorm Watch 294 continues. SUMMARY...A severe threat is expected to continue for several more hours across southwestern and south-central Nebraska, and may affect parts of central and eastern Nebraska late this evening. Large hail, severe wind gusts and an isolated tornado threat will be possible. New weather watch issuance will be needed to the east of the ongoing watch. DISCUSSION...The latest hi-resolution radar imagery from Hasting, NE shows a short intense line segment just to the west of North Platte. This storm complex is located on the northwestern edge of a strongly unstable airmass, where surface dewpoints are in the lower 60s F and the RAP is estimating MLCAPE in the 2000 to 3000 J/kg range. The line will continue to move east-southeastward along the northern edge of this airmass into south-central Nebraska over the next few hours. RAP forecast soundings in south-central Nebraska have 0-6 km shear around 40 knots with 700-500 mb lapse rates near 7.5 C/km. This should continue to support supercell development, with a potential for large hail. However, linear mode may be favored as the line of strong to severe storms expands as it moves eastward into central and eastern Nebraska. Severe wind gusts are expected with the more intense parts of the line. ..Broyles/Thompson.. 05/24/2024 ...Please see www.spc.noaa.gov for graphic product...
