Public Severe Weather Outlook
PUBLIC SEVERE WEATHER OUTLOOK NWS STORM PREDICTION CENTER NORMAN OK 0420 PM CDT SUN JUN 07 2026 ...Severe thunderstorms expected over parts of the northern Plains this afternoon and tonight... * LOCATIONS... Western and Central North Dakota Eastern Montana Western South Dakota * HAZARDS... Widespread hurricane-force damaging winds A couple tornadoes Isolated large hail up to baseball size * SUMMARY... A bow echo thunderstorm complex with widespread damaging winds and significant severe gusts up to 100 mph appear likely over parts of the northern Plains this afternoon and evening. Scattered large hail and isolated tornadoes are also possible. Preparedness actions... Review your severe weather safety procedures for the possibility of dangerous weather today. Stay tuned to NOAA Weather Radio, weather.gov, or other media for watches and warnings. A watch means that conditions are favorable for severe thunderstorms over the next several hours. If a severe thunderstorm warning is issued for your area, move to a place of safety, ideally in an interior room on the lowest floor of a sturdy building. && ..Gleason.. 06/07/2026 Read more

SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0800 PM CDT Sun Jun 07 2026 Valid 080100Z - 081200Z ...THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF WESTERN NORTH DAKOTA AND FAR NORTHWESTERN SOUTH DAKOTA... ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS SOUTHWEST AND SOUTH-CENTRAL MISSOURI... ...SUMMARY... A line of severe thunderstorms with wind gusts potentially above 75 mph is expected over the northern High Plains this evening, with large to very large hail and an isolated tornado threat also possible. A couple of tornadoes and isolated damaging gusts are also possible in the Ozarks. ...Northern High Plains... At mid-levels, an upper-level trough is moving eastward into the northern Rockies. Further east, a lead shortwave trough is evident on water vapor imagery over the northern High Plains. At the surface, a 994 mb low is located in northwestern North Dakota with a surface trough extending southward into northwestern South Dakota. A cold front is in far western North Dakota. To the east of the front, surface dewpoints are mostly in the upper 50s and lower 60s F, and moderate instability is in place. Numerous thunderstorms have recently developed to the west of the instability axis, and these storms are expected to organize into an intense line segment over the next couple of hours. RAP forecast soundings in western North Dakota ahead of the storms have 0-6 km shear in the 40 to 55 knot range, with 850 to 500 mb lapse rates between 7.5 and 8 C/km. In addition, surface temperature-dewpoint spreads exceed 25 degrees F over much area. This environment will be very favorable for severe wind gusts. The greatest potential for severe gusts will be from far northwest South Dakota northeastward into much of western and north-central North Dakota. Along this corridor, a nearly continuous bowing line is expected to organize. Severe wind gusts above 75 mph will be possible with the more intense segments. In addition to the wind-damage threat, large to very large hail will be possible over the next couple hours with storms that obtain supercell structure. A tornado or two could also occur. ...Ozarks... A mid-level trough will move northeastward across the central U.S. this evening. Ahead of the trough, a moist and unstable airmass is in place from the southern and central Plains eastward into the lower to mid Mississippi Valley. Scattered strong thunderstorms are ongoing along an axis of moderate instability over the Ozarks of southern and central Missouri, where the RAP has MLCAPE in the 1500 to 2000 J/kg range. Ahead of the mid-level trough, low-level flow is forecast to become maximized in the Ozarks over the next couple of hours. Forecast soundings near Springfield, Missouri by 03Z have 0-3 km storm-relative helicity around 180 m2/s2. This will support a tornado threat. A few strong wind gusts will also be possible. ..Broyles.. 06/08/2026 Read more

WW 284 TORNADO AR MO 071930Z - 080000Z
URGENT - IMMEDIATE BROADCAST REQUESTED Tornado Watch Number 284 NWS Storm Prediction Center Norman OK 230 PM CDT Sun Jun 7 2026 The NWS Storm Prediction Center has issued a * Tornado Watch for portions of Northwest Arkansas Southwest Missouri * Effective this Sunday afternoon and evening from 230 PM until 700 PM CDT. * Primary threats include... A couple tornadoes possible Scattered damaging wind gusts to 60 mph possible SUMMARY...A few supercells will probably continue to mature across the Watch area ahead of a weak mid-level disturbance approaching the Ozarks. A couple of brief tornadoes are possible with the stronger, more persistent cells through the late afternoon and into the early evening. Isolated damaging wind gusts are also possible. The tornado watch area is approximately along and 45 statute miles east and west of a line from 60 miles north of Springfield MO to 30 miles south of Harrison AR. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU4). 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 0.5 inches. Extreme turbulence and surface wind gusts to 50 knots. A few cumulonimbi with maximum tops to 400. Mean storm motion vector 20020. ...Smith Read more

MD 1018 CONCERNING SEVERE THUNDERSTORM WATCH 285... FOR SOUTHEASTERN MT...NORTHWEST SOUTH DAKOTA AND WESTERN NORTH DAKOTA
Mesoscale Discussion 1018 NWS Storm Prediction Center Norman OK 0612 PM CDT Sun Jun 07 2026 Areas affected...southeastern MT...northwest South Dakota and western North Dakota Concerning...Severe Thunderstorm Watch 285... Valid 072312Z - 080045Z The severe weather threat for Severe Thunderstorm Watch 285 continues. SUMMARY...Supercells over southeastern MT are showing initial signs of upscale growth. An organized cluster or bow may result. The environment is favorable for a significant damaging wind risk (gusts greater than 75 mph) which may begin in the next 1-2 hours. DISCUSSION...Across PDS SVR Watch #285, initial supercell clusters have remained severe with large hail, but have shown signs of consolidation. The environment remains strongly unstable and sheared with MLCAPE in excess of 2500 J/kg and 45-55 kt of deep-layer shear supporting organized and intense thunderstorms. T/TD spreads as highs 40 degrees F will favor strong downdrafts with the potential for severe outflow winds. This, combined with enhanced convergence near the frontal boundary will favor numerous storm interactions and the development of new updrafts in close proximity to the ongoing storms. Exact convective evolution remains somewhat unclear, but initial upscale growth is likely occurring. This is supported by the change in radar presentation of the storms over southern Custer County in MT, with multiple strong updrafts observed and lengthening storm motion vectors. If a sufficient cold pool can organize, a highly organized cluster or bowing complex may result. Given the very favorable environment, this would support a significant damaging wind risk with gusts greater than 75 mph. CAM trends along with the aforementioned observational data suggest this is likely in the next 30-90 minutes. ..Lyons.. 06/07/2026 ...Please see www.spc.noaa.gov for graphic product...

Valid 072345Z - 080115Z The severe weather threat for Severe Thunderstorm Watch 285 continues. SUMMARY...Severe supercells along the cold front will pose a risk for hail, damaging winds and a tornado or two this evening. Eventually upscale growth into a line with a risk for significant damaging winds is possible. DISCUSSION...Several supercells have rapidly intensified along and behind the sagging cold front across northwestern ND. Richer low-level moisture (mid to upper 60s F surface dewpoints) along the cool side of the boundary is supporting large buoyancy amid strongly veering wind profiles. Hail (some greater than 2 inches) is likely with these initial supercells. Low-level moisture may also be sufficient for a couple of tornadoes given the strong low-level buoyancy and enhanced vertical vorticity along the front. Eventually the convection emanating out of MT and SD, as well as the surging front will favor upscale growth into linear clusters. The strong buoyancy and vertical shear would support a risk for damaging winds, some of which could be significant. ..Lyons.. 06/07/2026 ...Please see www.spc.noaa.gov for graphic product...
