MD 1669 CONCERNING SEVERE THUNDERSTORM WATCH 499... FOR EASTERN ND/NORTHEAST SD INTO WEST-CENTRAL/NORTHWEST MN
Mesoscale Discussion 1669 NWS Storm Prediction Center Norman OK 1142 PM CDT Sun Jul 19 2026 Areas affected...Eastern ND/northeast SD into west-central/northwest MN Concerning...Severe Thunderstorm Watch 499... Valid 200442Z - 200545Z The severe weather threat for Severe Thunderstorm Watch 499 continues. SUMMARY...A short-term threat for isolated severe hail/wind may spread across far northeast South Dakota into west-central Minnesota. Additional strong to severe storm development is possible into the overnight into eastern North Dakota and northwest Minnesota, though coverage and timing remains very uncertain. DISCUSSION...A persistent and occasionally severe storm cluster is approaching the northeast corner of SD as of 0440 UTC. In the short term, moderate elevated buoyancy and favorable effective shear (as observed earlier in the prefrontal 00Z soundings from BIS and ABR) will continue to support some severe wind/hail threat. Longevity of this cluster is uncertain due to increasing CINH and generally modest large-scale ascent, but some severe threat could accompany this cluster as it moves into west-central MN during the early overnight hours. Farther north, a conditionally favorable environment remains in place across eastern ND into far northwest MN, along/ahead of a cold front. Short-term guidance continues to vary considerably regarding the timing and coverage (if any) of elevated storm development in this area into the overnight hours. Should sustained storms develop within this region, MUCAPE of 2000-3000 J/kg and favorable deep-layer shear would support a threat for severe wind and hail. With generally weak ascent and only a modest low-level jet response anticipated, potential for more than isolated strong to severe storm development overnight remains very uncertain. However, watch issuance will become possible if trends support development of multiple severe storms. ..Dean/Hart.. 07/20/2026 ...Please see www.spc.noaa.gov for graphic product...

MD 1668 CONCERNING SEVERE THUNDERSTORM WATCH 499... FOR SOUTH-CENTRAL/SOUTHEAST ND AND NORTH-CENTRAL/NORTHEAST SD
Mesoscale Discussion 1668 NWS Storm Prediction Center Norman OK 0912 PM CDT Sun Jul 19 2026 Areas affected...south-central/southeast ND and north-central/northeast SD Concerning...Severe Thunderstorm Watch 499... Valid 200212Z - 200345Z The severe weather threat for Severe Thunderstorm Watch 499 continues. SUMMARY...The risk of severe wind gusts will continue spreading eastward across parts of Severe Thunderstorm Watch 499. Some severe risk may extend eastward out of the watch, and convective trends are being monitored. DISCUSSION...The latest radar data from KBIS indicates some signs of a consolidating cold pool as storms continue spreading eastward across south-central ND and north-central SD. In the near-term, isolated severe hail and locally damaging gusts are the primary concerns with an evolving cluster and splitting cells. The ABR 00Z sounding sampled steep midlevel lapse rates atop a warm and very moist PBL (middle 70s dewpoints), resulting in a strongly unstable downstream air mass. This, combined with around 50 kt of effective shear oriented perpendicular to the evolving gust front, could support a continued risk of severe wind gusts east of Severe Thunderstorm Watch 499. However, some lingering low-level inhibition in the ABR sounding and a gradual increase in nocturnal static stability may temper the overall risk. Current thinking is that a downstream watch will not be needed, though convective trends are being monitored. ..Weinman/Hart.. 07/20/2026 ...Please see www.spc.noaa.gov for graphic product...

WW 499 SEVERE TSTM ND SD 192125Z - 200400Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 499 NWS Storm Prediction Center Norman OK 425 PM CDT Sun Jul 19 2026 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Central North Dakota Northern South Dakota * Effective this Sunday afternoon and evening from 425 PM until 1100 PM CDT. * Primary threats include... Scattered damaging wind gusts to 70 mph likely Scattered large hail events to 1.5 inches in diameter likely SUMMARY...Thunderstorms are expected to develop and spread east-southeastward across the watch area this evening. Locally damaging wind gusts and hail are possible with the strongest storms. The severe thunderstorm watch area is approximately along and 80 statute miles east and west of a line from 65 miles north northeast of Bismarck ND to 35 miles south southeast of Mobridge SD. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU9). 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 498... AVIATION...A few severe thunderstorms with hail surface and aloft to 1.5 inches. Extreme turbulence and surface wind gusts to 60 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 29025. ...Hart Read more

MD 1667 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR PARTS OF SOUTH-CENTRAL SD INTO NORTH-CENTRAL/NORTHEAST NE

The severe risk is expected to remain too localized for a watch. DISCUSSION...A northeast/southwest-oriented cluster of thunderstorms is evolving along a surface wind shift in south-central SD. Downstream of these storms, temperatures have warmed into the middle/upper 90s amid middle/upper 60s to lower 70s dewpoints -- yielding moderate surface-based buoyancy. Over the next couple of hours, thunderstorms will track southeastward along the buoyancy gradient amid 30-40 kt of northwesterly deep-layer shear. This could support a loosely organized cluster of thunderstorms capable of producing a few severe wind gusts. The overall severe risk is expected to remain sufficiently localized to preclude a watch issuance. ..Weinman/Hart.. 07/20/2026 ...Please see www.spc.noaa.gov for graphic product...

Valid 192348Z - 200145Z The severe weather threat for Severe Thunderstorm Watch 499 continues. SUMMARY...The risk of severe wind gusts and large hail will continue to increase in coverage over the next couple of hours -- within Severe Thunderstorm Watch 499. DISCUSSION...Over the last 30 minutes or so, an increase in thunderstorm intensity and coverage has begun, as storms impinge on a plume of lower 70s dewpoints and at least 2000 J/kg MLCAPE per modified 18Z BIS sounding and the latest HRRR SFCOA data. As storms continue spreading/developing eastward, increasing buoyancy will support further intensification of ongoing storms. The BIS VWP is sampling a long/straight hodograph (40-50 kt of 0-6 km shear), which will continue to promote splitting supercells capable of producing severe wind gusts and large hail. Resultant storm mergers and increasingly robust outflow will favor a gradual increase in both the coverage and intensity of severe wind gusts over the next couple of hours. ..Weinman.. 07/19/2026 ...Please see www.spc.noaa.gov for graphic product...
