WW 476 TORNADO ND 272145Z - 280300Z
URGENT - IMMEDIATE BROADCAST REQUESTED Tornado Watch Number 476 NWS Storm Prediction Center Norman OK 345 PM MDT Thu Jun 27 2024 The NWS Storm Prediction Center has issued a * Tornado Watch for portions of Western North Dakota * Effective this Thursday afternoon and evening from 345 PM until 900 PM MDT. * Primary threats include... A couple tornadoes possible Widespread damaging winds and isolated significant gusts to 80 mph likely Scattered large hail and isolated very large hail events to 3 inches in diameter likely SUMMARY...Isolated supercells will possibly develop late this afternoon into the evening across western North Dakota. In addition to the threat for a couple of tornadoes, a risk for large to very large hail (diameters 1 to 3 inches) and severe gusts will also accompany any discrete supercells. A band of severe thunderstorms is forecast to move west to east across the Watch area later this evening. A risk for a tornado may exist with any supercell embedded within the broken band. Severe gusts (60-80 mph) will be likely with the more intense portions of the band of storms. The tornado watch area is approximately along and 45 statute miles east and west of a line from 55 miles north northeast of Williston ND to 60 miles south southwest of Dickinson ND. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU6). 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. && OTHER WATCH INFORMATION...CONTINUE...WW 473...WW 474...WW 475... AVIATION...Tornadoes and a few severe thunderstorms with hail surface and aloft to 3 inches. Extreme turbulence and surface wind gusts to 70 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 26030. ...Smith Read more

Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0814 PM CDT Thu Jun 27 2024 Valid 280100Z - 281200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE NORTHERN PLAINS... ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE SOUTHERN HIGH PLAINS.... ...SUMMARY... The greatest severe-thunderstorm threat is over parts of the northern/central High Plains this evening and tonight. Severe gusts, including some 75+ mph are possible. ...Northern and central Plains... An upper low over the northern Rockies will continue to overspread a warm and moist air mass across the northern Plains this evening. As an attendant surface low deepens, strong mass response and an increasing low-level jet will support further intensification of an ongoing MCS over the western Dakotas. This MCS should continue east/southeast with the potential for severe wind gusts (some 75+ mph) and perhaps a tornado with embedded QLCS circulations. Convection should begin to weaken as it approaches the eastern edge of the buoyancy plume across east-central ND/SD later tonight. Sporadic storms farther south have struggled to remain organized amid warm mid-level temperatures. Isolated storms will remain possible this evening under weak ascent from the northern Rockies upper low and the increase in the nocturnal low-level jet. Moderate buoyancy and 30-40 kt of effective shear support a risk for organized storms capable of hail and damaging gusts, though confidence in convective evolution is low. ...Southern Plains... A loosely organized cluster of storms ongoing from the TX/OK Panhandles into southwest KS should continue eastward within a hot and moist air mass across the southern Plains. Deep-layer shear remains rather weak, but an increase in the low-level jet could support some intensification and additional storm development over southern KS this evening. Damaging gusts and sporadic hail will remain possible before convection gradually diminishes tonight. ...Eastern Great Basin and Southwest... Scattered storms over the Western Slope and Southwest should continue this evening as ascent from the northern Rockies upper low continues over seasonably high moisture. Storm coverage will slowly diminish as buoyancy continues to decrease in the wake of air mass overturning. Still, residual storms interacting with 30-40 kt of mid-level flow could support the risk for an isolated damaging gust or sporadic hail for a few more hours. ..Lyons.. 06/28/2024 Read more

Still, residual storms interacting with 30-40 kt of mid-level flow could support the risk for an isolated damaging gust or sporadic hail for a few more hours. ..Lyons.. 06/28/2024 Read more

SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0814 PM CDT Thu Jun 27 2024 Valid 280100Z - 281200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE NORTHERN PLAINS... ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE SOUTHERN HIGH PLAINS.... ...SUMMARY... The greatest severe-thunderstorm threat is over parts of the northern/central High Plains this evening and tonight. Severe gusts, including some 75+ mph are possible. ...Northern and central Plains... An upper low over the northern Rockies will continue to overspread a warm and moist air mass across the northern Plains this evening. As an attendant surface low deepens, strong mass response and an increasing low-level jet will support further intensification of an ongoing MCS over the western Dakotas. This MCS should continue east/southeast with the potential for severe wind gusts (some 75+ mph) and perhaps a tornado with embedded QLCS circulations. Convection should begin to weaken as it approaches the eastern edge of the buoyancy plume across east-central ND/SD later tonight. Sporadic storms farther south have struggled to remain organized amid warm mid-level temperatures. Isolated storms will remain possible this evening under weak ascent from the northern Rockies upper low and the increase in the nocturnal low-level jet. Moderate buoyancy and 30-40 kt of effective shear support a risk for organized storms capable of hail and damaging gusts, though confidence in convective evolution is low. ...Southern Plains... A loosely organized cluster of storms ongoing from the TX/OK Panhandles into southwest KS should continue eastward within a hot and moist air mass across the southern Plains. Deep-layer shear remains rather weak, but an increase in the low-level jet could support some intensification and additional storm development over southern KS this evening. Damaging gusts and sporadic hail will remain possible before convection gradually diminishes tonight. ...Eastern Great Basin and Southwest... Scattered storms over the Western Slope and Southwest should continue this evening as ascent from the northern Rockies upper low continues over seasonably high moisture. Storm coverage will slowly diminish as buoyancy continues to decrease in the wake of air mass overturning. Still, residual storms interacting with 30-40 kt of mid-level flow could support the risk for an isolated damaging gust or sporadic hail for a few more hours. ..Lyons.. 06/28/2024 Read more
