Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0750 PM CDT Tue Jul 15 2025 Valid 160100Z - 161200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS OVER PORTIONS OF CENTRAL NEBRASKA... ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS OVER NORTH-CENTRAL WYOMING... ...SUMMARY... Scattered severe gusts (some 75+ mph) and large hail are probable across parts of central Nebraska this evening. Isolated severe gusts are also possible from the Upper Midwest to Utah and Wyoming through mid-evening. ...SD/NE... An organized linear MCS has become established from eastern SD into central NE. These storms have product several reports of locally damaging winds and some large hail. This QLCS will progress east-southeastward through the evening into western IA and southeast NE, with a continued severe threat. Reference MCD #1679 and WW #514 for further details. ...Northern WY/Western Upper MI... A line of intense thunderstorms is tracking eastward along and south of the WI/Upper MI state line. These storms have produced sporadic damaging wind gusts over the last few hours, and are probably past-peak. Nevertheless, a few severe storms will remain possible for another 2-3 hours. Reference WW #513 for further details. ...WY... Scattered high-based thunderstorms continue to develop and spread across much of western and central WY. The strongest cells in this area will maintain some risk of damaging wind gusts for a few more hours until diurnal cooling diminishes the threat. Reference WW #515 for further details. ...Southeast AZ... Scattered thunderstorms continue to develop in a warm/moist environment over southeast AZ. This activity will slowly build westward for the next several hours, with a risk of gusty/damaging winds. Reference MCD #1680 for further details. ..Hart.. 07/16/2025 Read more

MD 1679 CONCERNING SEVERE THUNDERSTORM WATCH 514... FOR SOUTHWESTERN THROUGH NORTHEASTERN NEBRASKA AND SOUTHEASTERN SOUTH DAKOTA
Mesoscale Discussion 1679 NWS Storm Prediction Center Norman OK 0549 PM CDT Tue Jul 15 2025 Areas affected...southwestern through northeastern Nebraska and southeastern South Dakota Concerning...Severe Thunderstorm Watch 514... Valid 152249Z - 160045Z The severe weather threat for Severe Thunderstorm Watch 514 continues. SUMMARY...Scattered strong storms posing a risk for severe hail may be accompanied by increasing downbursts during the next few couple of hours, before gradually organizing and advancing southeastward with a continuing risk for strong to severe gusts through 7-9 PM CDT. DISCUSSION...Still generally focused along the pre-frontal surface trough, as it is gradually overtaken by the southward advancing cold front, thunderstorm development continues to increase and intensify. This appears to be occurring beneath the 500 mb cold core (-8 to -10C) of weak mid-level troughing advancing eastward across South Dakota and Nebraska, where southwesterly deep-layer mean flow is a rather modest 10-20 kt. Veering of wind fields with height is contributing to modest shear, however, supportive of widely scattered supercell structures posing a risk for severe hail. Although it will be several more hours before a nocturnally strengthening southerly low-level jet may become an influence across parts of central Nebraska, ongoing storms may pose an increasing risk for downbursts over the next few hours, before outflow begins to conglomerate and the more intense convection becomes focused along the leading edge of southeastward outflow surges through 00-02Z. ..Kerr.. 07/15/2025 ...Please see www.spc.noaa.gov for graphic product...

MD 1678 CONCERNING SEVERE THUNDERSTORM WATCH 513... FOR CENTRAL MINNESOTA...NORTHERN WISCONSIN. UPPER MICHIGAN
Mesoscale Discussion 1678 NWS Storm Prediction Center Norman OK 0510 PM CDT Tue Jul 15 2025 Areas affected...central Minnesota...northern Wisconsin. Upper Michigan Concerning...Severe Thunderstorm Watch 513... Valid 152210Z - 160015Z The severe weather threat for Severe Thunderstorm Watch 513 continues. SUMMARY...Threat for severe wind and occasional severe hail continues within WW513. DISCUSSION...Broken lines of thunderstorm activity continue near the surface cold front across central Minnesota into northern Wisconsin and the Upper Michigan Peninsula. Deep layer shear around 20-30 kts is largely parallel to and located near the cold front. As such, some disorganized mainly multi-cell clusters continue to track east-northeastward. South of the cold front, shear decreases but steep low level lapse rates around 8-8.5 C/km and a very warm/unstable air mass will continue to support instances of severe gusts. Some marginally severe hail may be possible near the cold front and in the vicinity of better deep layer shear. ..Thornton.. 07/15/2025 ...Please see www.spc.noaa.gov for graphic product...

URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 513 NWS Storm Prediction Center Norman OK 255 PM CDT Tue Jul 15 2025 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Upper Peninsula Michigan Central and North-Central Minnesota Northern Wisconsin Lake Superior * Effective this Tuesday afternoon and evening from 255 PM until 1000 PM CDT. * Primary threats include... Scattered large hail and isolated very large hail events to 2 inches in diameter possible Scattered damaging wind gusts to 70 mph possible SUMMARY...Scattered clusters of strong to severe thunderstorms will likely develop through the remainder of the afternoon and persist into the evening. The stronger thunderstorms will be capable of a risk for large hail and severe gusts. The severe thunderstorm watch area is approximately along and 45 statute miles north and south of a line from 30 miles south southwest of Alexandria MN to 115 miles east of Ironwood MI. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU3). 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. && AVIATION...A few severe thunderstorms with hail surface and aloft to 2 inches. Extreme turbulence and surface wind gusts to 60 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 26025. ...Smith Read more

DISCUSSION...Broken lines of thunderstorm activity continue near the surface cold front across central Minnesota into northern Wisconsin and the Upper Michigan Peninsula. Deep layer shear around 20-30 kts is largely parallel to and located near the cold front. As such, some disorganized mainly multi-cell clusters continue to track east-northeastward. South of the cold front, shear decreases but steep low level lapse rates around 8-8.5 C/km and a very warm/unstable air mass will continue to support instances of severe gusts. Some marginally severe hail may be possible near the cold front and in the vicinity of better deep layer shear. ..Thornton.. 07/15/2025 ...Please see www.spc.noaa.gov for graphic product...
