Severe Storms

SPC 1200Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1259 AM CDT Mon Jun 16 2025 Valid 161200Z - 171200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS OVER PARTS OF THE UPPER MIDWEST AND THE CENTRAL PLAINS... ...SUMMARY... Scattered severe thunderstorms capable of producing severe gusts, large hail, and perhaps a couple tornadoes are forecast today from the north-central High Plains into the Upper Mississippi Valley. ...Synopsis... Within a belt of zonal midlevel flow extending from the northern Rockies/High Plains into the Upper MS Valley, a convectively augmented midlevel impulse/MCV will track eastward across the Dakotas into MN through the afternoon. In response to this feature, a weak frontal-wave low will migrate eastward from the eastern Dakotas into MN -- along a surface boundary extending southwestward through the central Plains. Farther west, an additional low-amplitude impulse accompanied by strong westerly flow aloft will emerge over the northern/central High Plains during the late afternoon/early evening. ...Upper MS Valley into the central Plains... Scattered thunderstorms should generally be focused along/ahead of the frontal-wave low and remnant MCV as it moves into MN during the afternoon, with additional trailing development possible along the surface boundary into NE. Here, rich boundary-layer moisture and modestly steep midlevel lapse rates will contribute to a strongly unstable air mass, while the enhanced midlevel westerly flow yields around 40 kt of effective shear. This should support a risk of a couple supercells and organized clusters capable of producing large hail, damaging winds, and a couple tornadoes. ...Southeast MT into the central High Plains... As low-level lapse rates diurnally steepen amid recycled/post-frontal boundary-layer moisture over the northern/central High Plains, scattered thunderstorms should evolve eastward from southeast MT/eastern WY into the central Plains -- aided by the emerging midlevel impulse. Upwards of 40-50 kt of effective shear and steepening deep-layer lapse rates will favor large hail and locally severe wind gusts with initial discrete/semi-discrete supercell structures and organized clusters. As these storms track east-southeastward into the evening, additional storms may be developing farther south along the southwestward-extending surface boundary over western/central NE/northeastern CO/northwest KS. While the overall convective evolution is unclear, current thinking is that multiple opportunities for upscale growth into one or more MCSs will exist in the NE/KS vicinity into the evening/overnight hours. A swath of severe wind will be possible where this evolution occurs. ..Weinman/Leitman.. 06/16/2025 Read more

MD 1309 CONCERNING SEVERE POTENTIAL...WATCH LIKELY FOR WESTERN NORTH DAKOTA
Mesoscale Discussion 1309 NWS Storm Prediction Center Norman OK 1030 PM CDT Sun Jun 15 2025 Areas affected...western North Dakota Concerning...Severe potential...Watch likely Valid 160330Z - 160530Z Probability of Watch Issuance...80 percent SUMMARY...Severe thunderstorms continue to move east across Montana this evening. With time, these storms will move east into North Dakota posing a risk for damaging winds and isolated large hail. A watch will likely be needed shortly for portions of North Dakota. DISCUSSION...Multiple clusters of severe thunderstorms continue this evening across eastern Montana within a strongly sheared and very buoyant airmass. These thunderstorms, aided by large-scale ascent from a shortwave trough moving through, should continue to merge together and grow upscale into a large MCS that progresses east into portions of western North Dakota. The airmass ahead of this line across North Dakota remains strongly sheared, and as buoyant or greater than areas to the west. Thus, with most-unstable CAPE ranging from 1000 J/kg near the Canadian border to more than 3000 J/kg across the North Dakota/South Dakota border, thunderstorms should be able to persist east of Severe Thunderstorm Watch #418. A severe thunderstorm watch will be needed across portions of North Dakota. ..Marsh/Smith.. 06/16/2025 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...BIS...
