SPC 1300Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0725 AM CDT Mon Jul 28 2025 Valid 281300Z - 291200Z ...THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS THIS AFTERNOON AND TONIGHT OVER PORTIONS OF EASTERN SOUTH DAKOTA AND SOUTHWESTERN MINNESOTA.... ...SUMMARY... Numerous severe thunderstorms capable of widespread damaging winds are likely across portions of the northern Plains, with several gusts expected to exceed 75 mph. A few line-embedded tornadoes and instances of severe hail may also occur. Widely scattered storms may produce severe wind and hail over portions of Montana. ...Northern Plains... A convectively active afternoon and evening is expected across parts of the Dakotas/MN/IA/WI, where numerous intense thunderstorms are expected. An overnight MCS has temporarily stabilized/modified the air mass across much of MN/IA. A consensus of model guidance appears to have handled this scenario well, and depicts rapid return of low-level moisture and heating across this region by mid-afternoon. Meanwhile upstream in eastern MT and western ND/SD, a subtle shortwave trough will top the ridge and spread large scale forcing into the region, leading to scattered thunderstorm development. Very steep mid-level lapse rates are in place across ND/SD, where easterly low-level winds and evapo-transpiration will help surface dewpoints to rise to near 70F. Forecast soundings show extreme instability will develop (MLCAPE values over 6000 J/kg) aiding in rapid intensification of supercells across central SD. Large hail, damaging winds, and a few tornadoes may occur with this early activity. The most likely scenario for evening convective activity continues to be for an organized and fast-moving linear MCS to develop and race eastward across eastern SD into parts of MN/IA. One or more corridors of widespread/significant wind damage are expected, possibly achieving derecho criteria. Have extended the ENH/SLGT risk areas a little farther east into parts of MN/IA/WI, where a few overnight CAM solutions suggest the bowing complex persists before weakening late tonight. ...Central MT... Easterly low-level winds across MT will advect moisture westward into the mountains, where scattered thunderstorm development is expected by late afternoon. These storms will spread into central MT during the evening, with sufficient CAPE and vertical shear for a risk of large hail and damaging wind gusts. ..Hart/Grams.. 07/28/2025 Read more

MD 1820 CONCERNING SEVERE POTENTIAL...WATCH POSSIBLE FOR EASTERN MT...WESTERN ND...AND FAR NORTHWEST SD
Mesoscale Discussion 1820 NWS Storm Prediction Center Norman OK 0502 AM CDT Mon Jul 28 2025 Areas affected...eastern MT...western ND...and far northwest SD Concerning...Severe potential...Watch possible Valid 281002Z - 281200Z Probability of Watch Issuance...40 percent SUMMARY...Isolated large hail and strong gusts are possible through mid-morning with initial elevated storms across the northern Great Plains. Some potential exists for greater than anticipated coverage which could warrant a Severe Thunderstorm Watch issuance. DISCUSSION...Elevated thunderstorms have been ongoing for the past several hours, but one cell has recently intensified near GDV. GSL-MPAS runs appear to be favorably handling this activity spatially, albeit slower than observed. The general expectation are for these storms to persist through daybreak into mid-morning, largely eastward in ND along the buoyancy gradient. A belt of enhanced mid-level westerlies, as sampled by the GGW VWP, will be sufficient for updraft rotation and a primary threat of large hail. Weak convection has also recently formed near the MT/ND/SD border area. If this activity intensifies as well, a broader cluster might emerge which could increase the severe wind threat later this morning. ..Grams/Hart.. 07/28/2025 ...Please see www.spc.noaa.gov for graphic product...

Day 4-8 Outlook
Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0349 AM CDT Mon Jul 28 2025 Valid 311200Z - 051200Z ...DISCUSSION... By late next week, the upper-level trough in the Northeast will be moving into the Canadian Maritimes. In its wake, high pressure at the surface will build into the Upper Midwest/Ohio Valley. This will push the surface front farther south each day through the weekend. In the West, cyclonic flow will tend to weaken over time. The surface front will be pushed up against the Rockies. Model guidance shows progressively lower amounts of buoyancy south of the front in the Southeast, likely due to repeated days of convection. This activity will also become farther removed from stronger shear. Winds with some upslope component with weak/modest westerlies aloft could allow for some severe risk near the Rockies and adjacent High Plains, but the overall weak shear and potential for sequential convective days leading to a poor quality airmass suggest the threat is like to remain marginal. Predictability of organized severe weather remains low. Read more
