Valid 272212Z - 272345Z The severe weather threat for Severe Thunderstorm Watch 474 continues. SUMMARY...The severe threat continues across Severe Thunderstorm Watch 474. Severe wind and hail remain the primary concerns through the rest of the evening. DISCUSSION...Scattered multicells and transient supercells persist across portions of UT into western CO, some of which have a history of severe hail and occasional strong wind gusts. 500-1000 J/kg MLCAPE remains across portions of the Interior West, which will support continued severe wind/hail potential through at least sunset. Severe gusts are more likely across Mesa into Montrose Counties in CO, where some congealing of multicells has recently occurred. ..Squitieri.. 06/27/2024 ...Please see www.spc.noaa.gov for graphic product...

MD 1450 CONCERNING SEVERE THUNDERSTORM WATCH 473... FOR PORTIONS OF SOUTHEASTERN MONTANA
Mesoscale Discussion 1450 NWS Storm Prediction Center Norman OK 0501 PM CDT Thu Jun 27 2024 Areas affected...Portions of southeastern Montana Concerning...Severe Thunderstorm Watch 473... Valid 272201Z - 272330Z The severe weather threat for Severe Thunderstorm Watch 473 continues. SUMMARY...The severe threat continues across Severe Thunderstorm Watch 473. Severe wind gusts (a few of which could reach 75-90 mph) are the main threat, though isolated instances of hail or even a tornado remain possible. DISCUSSION...Multicells and transient supercells are merging into a singular MCS across portions of southeastern Montana. These storms have been traversing a mixed boundary layer (characterized by 9.5 C/km 0-3 km lapse rates per 21Z mesoanalysis), with a history of producing multiple severe gusts. Preceding the upscale growing MCS is a warm sector that moistens with eastward extent, with 60s F dewpoints beneath 7.5 C/km mid-level lapse rates contributing to 2000-3000 J/kg MLCAPE near the MT/ND border. Given widespread 50+ kt effective bulk shear, the MCS should at least maintain intensity through the evening. However, deep-layer shear vectors become more perpendicular to MCS orientation with eastward extent, which may promote further organization into a bow-echo MCS with increased severe gust potential. A few 75-90 mph gusts may occur near the apex of any bow echo that can form, with large hail possible with any stronger storm cores. A tornado also cannot be ruled out with any mesovortices that can become established. ..Squitieri.. 06/27/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...BYZ...GGW...

Mesoscale Discussion 1449 NWS Storm Prediction Center Norman OK 0447 PM CDT Thu Jun 27 2024 Areas affected...northeastern New Mexico...southeastern Colorado...southwestern Kansas...and portions of the Oklahoma/Texas Panhandles Concerning...Severe potential...Watch possible Valid 272147Z - 272315Z Probability of Watch Issuance...40 percent SUMMARY...Storms developing across portions of the central/southern High Plains region from southeastern Colorado/northeastern New Mexico northeastward into southwestern Kansas will pose increasing risk for locally severe wind gusts. WW may be required in the next hour. DISCUSSION...Latest radar loop shows storms gradually increasing in coverage from northeastern New Mexico and adjacent southeastern Colorado, to near of KTQX (Scott City, KS). The storms are occurring in a hot/deeply mixed boundary layer, where modest CAPE above the LCL is supporting a few stronger updrafts. The development appears to be occurring in part due to response of the environment to a very subtle/mid-level disturbance moving eastward across southern Colorado at this time. While a more unstable airmass -- and thus potential for more robust convection -- exists farther north, into northwestern Kansas and points north, the deep/dry boundary layer will promote potential for evaporatively enhanced downdrafts, and associated potential for severe-caliber gusts locally. We will continue to monitor this region in the short term, for signs that risk may increase in coverage, which could support the need to consider WW issuance. ..Goss/Smith.. 06/27/2024 ...Please see www.spc.noaa.gov for graphic product...

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...

MD 1448 CONCERNING SEVERE THUNDERSTORM WATCH 473... FOR PORTIONS OF FAR EASTERN MONTANA AND WESTERN NORTH DAKOTA
Mesoscale Discussion 1448 NWS Storm Prediction Center Norman OK 0357 PM CDT Thu Jun 27 2024 Areas affected...Portions of far eastern Montana and western North Dakota Concerning...Severe Thunderstorm Watch 473... Valid 272057Z - 272230Z The severe weather threat for Severe Thunderstorm Watch 473 continues. SUMMARY...Severe risk is increasing across far eastern Montana into western ND, including the potential for large hail, damaging winds, and perhaps a tornado or two. DISCUSSION...Cumulus is deepening along an effective warm front extending east-southeastward from eastern MT into western ND, and isolated convective initiation is underway over Wibaux County MT. Regional VWP shows ample low-level hodograph curvature associated with backed surface winds beneath a plume of strong low-level warm-air advection. Additionally, diurnal heating along the boundary has yielded moderate surface-based instability. These factors, along with around 50 kt of effective shear, could support a couple semi-discrete supercells. Large hail and damaging winds are the main concern, though the favorable low-level hodograph curvature could support a tornado threat as well. A watch will eventually be needed into western North Dakota for the above-mentioned severe risk and for severe storms tracking eastward out of eastern Montana. ..Weinman/Hart.. 06/27/2024 ...Please see www.spc.noaa.gov for graphic product...

MD 1447 CONCERNING SEVERE POTENTIAL...SEVERE THUNDERSTORM WATCH LIKELY FOR PORTIONS OF THE CENTRAL AND NORTHERN HIGH PLAINS
Mesoscale Discussion 1447 NWS Storm Prediction Center Norman OK 0318 PM CDT Thu Jun 27 2024 Areas affected...Portions of the central and northern High Plains Concerning...Severe potential...Severe Thunderstorm Watch likely Valid 272018Z - 272145Z Probability of Watch Issuance...95 percent SUMMARY...Monitoring the area for increasing severe-storm potential this afternoon. A watch will be needed for parts of the area within the hour. DISCUSSION...Deepening boundary-layer cumulus is evident in the vicinity of the Black Hills as well as far northeast CO into the NE Panhandle this afternoon -- generally focused along a lee trough/surface wind shift. During the next couple hours, the lee trough will deepen as midlevel westerly flow strengthens across the northern and central Rockies. This will support a gradual increase in thunderstorm development over the next few hours, given diurnal heating of a moist air mass (upper 50s to middle/upper 60s dewpoints) and removal of MLCINH along the lee trough. Storms should generally track eastward into the increasingly rich moisture, where steep midlevel lapse rates are yielding moderate surface-based instability. The 19Z UNR special sounding showed around 30 kt of effective shear, characterized by a long/mostly straight hodograph, and deep-layer shear should strengthen to around 40-50 kt with time. As a result, storms should organize into semi-discrete supercells and organized clusters, with a risk of very large hail (potentially up to 3 inches) and severe gusts. A watch issuance is likely for parts of the area within the hour. ..Weinman/Hart.. 06/27/2024 ...Please see www.spc.noaa.gov for graphic product...

DISCUSSION...Visible satellite and radar shows storms already developing over the higher terrain, with occasional signs of brief hail over southwest UT. Precipitable water values around around 1.00" over the entire region, which when combined with heating is resulting in over 1000 J/kg MLCAPE. While the main shortwave trough will move north of the area, midlevel westerlies will increase to over 40 kt, elongating hodographs. Combined with steepening lapse rates, this should prove favorable for cells or small bows capable of damaging winds and marginal hail. As remaining inhibition is erased this afternoon, storms are likely to proceed across the lower elevations and sustain. As such, a watch is being considered. ..Jewell/Hart.. 06/27/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...RIW...GJT...SLC...
