WW 475 SEVERE TSTM CO KS NE SD WY 272040Z - 280300Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 475 NWS Storm Prediction Center Norman OK 240 PM MDT Thu Jun 27 2024 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Eastern Colorado Northwest Kansas Western Nebraska Western South Dakota Northeast Wyoming * Effective this Thursday afternoon and evening from 240 PM until 900 PM MDT. * Primary threats include... Scattered damaging winds and isolated significant gusts to 75 mph likely Scattered large hail and isolated very large hail events to 3 inches in diameter likely A tornado or two possible SUMMARY...Cluster of strong to severe thunderstorms are expected to track across the watch area this afternoon and evening. A few supercells capable of very large hail, damaging winds, and a tornado or two are possible. The severe thunderstorm watch area is approximately along and 60 statute miles east and west of a line from 35 miles northeast of Buffalo SD to 45 miles south of Goodland KS. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU5). 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 473...WW 474... AVIATION...A few severe thunderstorms with hail surface and aloft to 3 inches. Extreme turbulence and surface wind gusts to 65 knots. A few cumulonimbi with maximum tops to 500.

MD 1453 CONCERNING SEVERE POTENTIAL...SEVERE THUNDERSTORM WATCH LIKELY FOR PORTIONS OF CENTRAL NORTH DAKOTA INTO CENTRAL SOUTH DAKOTA
Mesoscale Discussion 1453 NWS Storm Prediction Center Norman OK 0621 PM CDT Thu Jun 27 2024 Areas affected...portions of central North Dakota into central South Dakota Concerning...Severe potential...Severe Thunderstorm Watch likely Valid 272321Z - 280045Z Probability of Watch Issuance...95 percent SUMMARY...The severe threat is increasing across portions of central ND into central SD as strong to potentially severe storms approach from the west. Severe gusts are the main threat, though some instances of severe hail and perhaps a tornado also may occur. A Severe Thunderstorm Watch issuance will be needed within the hour. DISCUSSION...Multicells and discrete supercells are moving across western SD/ND and are approaching the eastern bounds of Severe Thunderstorm Watch 475 and Tornado Watch 476. Meanwhile, a mature MCS continues to rapidly propagate eastward into ND from MT, and is poised to reach central ND in the next few hours. As these storms merge and approach central SD/ND, severe gusts will become likely as the storms move into a strongly unstable airmass (characterized by up to 3500 J/kg MLCAPE per 23Z mesoanalysis). Furthermore, the strengthening of the southerly LLJ (to 40+ kts), beneath increasing westerly 500 mb flow with the ejection of a mid-level vort max, will support effective bulk shear values well over 50 kts. Regional VADs and short-term RUC forecasts show enlarged and curved low-level hodographs with modest mid-level elongation. As such, any storms that remain surface based as they move into the central Dakotas should be accompanied by a severe threat. The eastward moving MCS should produce at least some severe wind, which is expected to be the predominant severe hazard. However, embedded mesovortices may be accompanied by an isolated tornado threat. A Severe Thunderstorm Watch will be issued within the hour to address the impending severe threat. ..Squitieri/Smith.. 06/27/2024 ...Please see www.spc.noaa.gov for graphic product...

MD 1452 CONCERNING TORNADO WATCH 476... FOR PORTIONS OF SOUTHWESTERN NORTH DAKOTA
Mesoscale Discussion 1452 NWS Storm Prediction Center Norman OK 0603 PM CDT Thu Jun 27 2024 Areas affected...portions of southwestern North Dakota Concerning...Tornado Watch 476... Valid 272303Z - 280030Z The severe weather threat for Tornado Watch 476 continues. SUMMARY...The severe threat continues across Tornado Watch 476. A few tornadoes remain possible with discrete supercells, but the severe wind threat should increase as an MCS overtakes the supercells in the next few hours. DISCUSSION...Two discrete supercells continue across southwestern ND as a well-developed MCS (with a history of severe gusts) approaches from southeastern MT. 22Z mesoanalysis shows modestly curved/elongated hodographs preceding the supercells, along with 200-300 m2/s2 effective SRH, supporting tornado potential. With time, the fast approaching MCS from the west will merge with the supercells. This may augment the severe wind threat, with 75-90 mph gusts possible. QLCS tornadoes will still be a concern as well. ..Squitieri.. 06/27/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...BIS...

MD 1454 CONCERNING SEVERE THUNDERSTORM WATCH 475... FOR NORTHEASTERN WYOMING INTO WESTERN SOUTH DAKOTA
Mesoscale Discussion 1454 NWS Storm Prediction Center Norman OK 0647 PM CDT Thu Jun 27 2024 Areas affected...northeastern Wyoming into western South Dakota Concerning...Severe Thunderstorm Watch 475... Valid 272347Z - 280145Z The severe weather threat for Severe Thunderstorm Watch 475 continues. SUMMARY...Risk for locally damaging gusts and isolated hail should gradually increase across northern portions of WW 475 over the next 1 to 2 hours. DISCUSSION...Latest radar loop shows isolated strong storms east of the Black hills, and a separate/expanding cluster of storms moving eastward out of southeastern Montana and northeastern Wyoming into northern portions of WW 475. With a moist/moderately unstable environment in the vicinity of the warm and cold fronts and the narrow warm sector in between, and veering flow with height providing ample shear for rotating storms, the overall environment remains supportive of large hail and damaging gusts with stronger storms. As such, as the convection spreads eastward into western South Dakota, severe risk should gradually increase. ..Goss.. 06/27/2024 ...Please see www.spc.noaa.gov for graphic product...
