Valid 071300Z - 081200Z
THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF SOUTHEAST MONTANA…NORTHEAST WYOMING…AND THE WESTERN DAKOTAS THIS AFTERNOON AND EVENING.
### SUMMARY
Severe thunderstorms with damaging wind gusts, large hail, and an isolated tornado threat are expected this afternoon and evening across parts of the northern Plains. An isolated threat for tornadoes and severe wind gusts will be possible across the Ozarks region. Strong wind gusts will also be possible in the mid Mississippi Valley and in the Mid-Atlantic.
MT/WY/Dakotas
A strong upper trough currently over the northern Great Basin will translate eastward today, with large scale forcing for ascent overspreading much of the northern High Plains region. This will aid cyclogenesis over eastern WY and focus a surface cold front from south-central WY into northwest ND. Thunderstorms are expected to form by mid-afternoon off the BigHorn mountains and build eastward across southeast MT. While this environment will be post-frontal, Relatively steep low-level lapse rates and moderate CAPE values will support a risk of large hail and damaging winds. Most CAM solutions suggest thunderstorms will become more numerous and intense as they spread into western SD this evening, maintaining support of the ENH risk area.
Ozarks
A weak cut-off low continues to drift northeastward across OK this morning. An associated band of 30-40 knot southwesterly mid-level winds and deep moisture will lie across the Ozark plateau today, where scattered thunderstorms are expected through the period. Parameters are rather weak across this region, but there will be some risk of locally damaging wind gusts or a tornado this afternoon/evening if pockets of daytime heating can occur.
Eastern VA/NC
A weak surface cold front is sagging southward across central VA this morning. A combination of strong heating and frontal forcing will lead to widely scattered thunderstorms this afternoon across southeast VA and northeast NC. The strongest of these cells could produce gusty winds.

Valid 081200Z - 091200Z
THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS OVER SOUTHEAST WYOMING…NORTHEAST COLORADO…AND THE SOUTHERN NEBRASKA PANHANDLE
### SUMMARY
Isolated to widely scattered severe storms capable of large to very large hail and perhaps a brief tornado or two are possible Monday afternoon and evening in northeast Colorado, southeast Wyoming, and the southern Nebraska Panhandle. Additional, more isolated occurrences of large hail and damaging winds will be possible from the Canadian border into the Oklahoma and Texas Panhandles. Sporadic damaging winds may occur from the Ozark Plateau into the Mid-south.
Synopsis
A mid-level jet streak and associated channeled vorticity maximum initially from the northern Rockies into northern High Plains will lift northeast into Manitoba, ahead of an amplifying short-wave trough moving through the Pacific Northwest into northern Rockies. Elsewhere, loosely organized troughing initially along the MS Valley will shift northeast into the Great Lakes and OH Valley.
At the surface, a front initially stretching from the central Dakotas to low pressure over western KS is expected to weaken through the day in response to falling pressures across the northern Rockies. A weak cyclone is expected to persist over southwest KS or northwest OK, with a dryline extending southwest into western TX.
### Great Plains
With the early-day passage of the lead short-wave trough through the northern High Plains, mid-level heights may rebound slightly during the afternoon, with negligible forcing for ascent indicated in model guidance. As such, the most probable location for isolated to widely scattered severe-storm development appears to be along favored terrain from north of the Palmer Divide to along the Cheyenne Ridge. There, moist upslope flow will become established by afternoon, beneath a plume of steep lapse rates, yielding MLCAPE of 1000-1500 J/kg. Vertical shear is expected to strengthen through the day with effective bulk shear increasing to around 50 kt by late afternoon into early evening. As such, the potential will exist for supercells capable of large to very large hail and perhaps a brief tornado or two. The severe-threat may move into the adjacent High Plains Monday evening before the storms weaken.
Across the lower elevations of the Plains there is considerably more model spread in the timing and location of storms through the forecast period, likely as a result of the weak forcing. The residual surface front from eastern SD through central NE into western KS, and south along the dryline into the OK/TX Panhandles will be viable locations for diurnally enhanced storms amidst a moderate to strongly unstable air mass. As such, isolated occurrences for large hail and severe wind gusts will be possible. Stronger deep-layer shear is forecast from northern KS into the northern Plains, which may support a longer-lived, more organized storm threat. However, given the model variability mentioned above, no additional level 2/Slight Risk areas will be highlighted with this forecast.
Finally, it appears a separate, elevated thunderstorm regime could materialize early Tuesday morning from parts of eastern MT through northern ND, where some large hail threat could develop.
### Ozark Plateau into the Mid-South
A number of models indicate the potential for a complex of thunderstorms to be ongoing Monday morning across portions of the Ozark Plateau, aided by low-level warm advection along a modest low-level jet. That activity is expected to continue east/southeast through the day, with some potential for cold pool organization and related damaging wind potential as the system encounters a moist and moderately unstable air mass.

NOTE: THE NEXT DAY 2 OUTLOOK IS SCHEDULED BY 1730Z
Scattered to numerous severe thunderstorms are expected to develop across portions of the northern Plains into Upper Mississippi Valley Tuesday afternoon into night. All severe-weather hazards are possible. Isolated to widely scattered severe storms may also occur across the central Plains, with a risk for large hail and damaging winds.

Valid 091200Z - 101200Z
THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS OVER CENTRAL NORTH DAKOTA AND NORTH-CENTRAL SOUTH DAKOTA
### SUMMARY
Scattered to numerous severe thunderstorms are expected to develop across portions of the northern Plains into Upper Mississippi Valley Tuesday afternoon into night. All severe-weather hazards are possible. Isolated to widely scattered severe storms may also occur across the central Plains, with a risk for large hail and damaging winds.
Synopsis
A short-wave trough and attending mid/upper-level jet streaks over the northern Rockies Tuesday morning will overspread the northern Plains by afternoon. Farther upstream, a significant short-wave trough will assume an increasing negative tilt while translating into the northern High Plains early Tuesday morning. At the surface, a cyclone linked with the lead short-wave trough will deepen while developing from southeast MT into western ND by afternoon. Meanwhile, an associated Pacific front will push east into the western Dakotas, with more of a dryline structure evident from southwest NE into the OK and TX Panhandles.
### Northern and Central Plains into Upper Mississippi Valley
An active severe-weather period is anticipated Tuesday afternoon into night, especially across the northern Plains, where all severe-weather hazards are possible.
While the pre-frontal air mass over the western Dakotas is not expected to be overly moist with dewpoints in the 50s to low 60s, strong daytime heating and steep mid-level lapse rates will contribute to moderate to strong instability by mid to late afternoon. Some potential for early-day storms will exist in northern ND, within a zone of persistent warm advection. Additional, more intense thunderstorm activity is expected by mid afternoon from the southern fringe of the early-day convection south along the front as forcing for ascent increases with the approach of the short-wave trough.
Vertically veering wind profiles with 40-50+ kt of deep-layer shear will favor supercells capable of large to very large hail initially. Some tornado threat could materialize during the evening hours as LCL heights lower and the low-level shear increases. With time, storms may grow upscale into clusters, with an increasing risk for damaging winds spreading east through the Red River Valley.
Farther south, a number of models develop isolated to widely scattered storms during the afternoon along the dryline in western KS amidst a marginally sheared, but moderate to strongly unstable environment. There is some signal that an MCS could evolve from that activity across the mid to lower MO Valley Tuesday evening. Only 5% total-severe probabilities will be added in those areas, due to uncertainty in that scenario.

You are looking at an outlook that is part of the medium range forecast (the outlook for days 4-8). The most important thing to note is that lack of a risk does not mean zero risk. Generally speaking, confidence has to be pretty high for the Storm Prediction Center to have an outlook area this far into the future.

Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0341 AM CDT Sun Jun 07 2026
Valid 101200Z - 151200Z
DISCUSSION
Day4/Wednesday
A concentrated area of potentially significant severe weather is expected Wednesday afternoon and evening, centered across portions of Minnesota, Wisconsin, and Iowa.
A number of the deterministic models have trended slightly faster with the progression of a lead short-wave trough and associated jet streak through the northern Plains into upper MS Valley. At the surface, low pressure initially over eastern SD is forecast to develop northeast along a cold front moving from the eastern Dakotas into MN. The trailing extension of the boundary is expected to move more slowly into the mid MO Valley before stalling in response to a deepening cyclone over the central High Plains.
Steep lapse rates and a very moist boundary layer will contribute to moderate to strong instability across the warm sector, with initial storms potentially developing by early afternoon from the Red River Valley into central MN. Subsequent storms are likely to develop across southern MN into IA and northern MO by mid to late afternoon. The models indicate 40+ kt deep-layer shear across the warm sector, supportive of supercells and bowing structures, capable of all severe-weather hazards. The severe-weather threat is expected to spread east through the upper Midwest during the evening hours.
### Day 5/Thursday
Both the ensemble mean and deterministic models indicate the development of a prominent mid-level low over Manitoba or northwest Ontario, with a potent short-wave trough moving through the base of that feature from the upper MS Valley through the upper Great Lakes. A belt of unseasonably strong mid-level winds will attend the short-wave trough from the central Plains into upper Great Lakes. At the surface, ensemble member clustering and the deterministic models indicate the primary low pressure over Ontario, with some signal for a secondary cyclone/frontal wave developing from the mid MO Valley into upper Midwest during the day. The associated surface front is forecast to advance through the upper Midwest into upper Great Lakes, with the trailing extension of the boundary moving into the mid MS Valley and southern Plains.
The presence of moderate to strong instability across the pre-frontal warm sector suggests the potential for severe storms from the upper Midwest into southern Plains. Within that broader envelope, a potentially more concentrated area of severe weather may materialize from parts of the upper Midwest into mid MS Valley during the afternoon and evening hours. There, the most favorable overlap of the forcing for ascent, sufficient vertical shear, and ample instability are expected to reside.
### Day 6/Friday
The ensembles and majority of deterministic models indicate the Day5/Thursday upper Great lakes short-wave trough will lift northeast into Ontario and Quebec. At the surface, the models suggest that a weakening cold front will advance into the Northeast and through the OH Valley. Some severe-weather threat could develop along the front by afternoon; however, the models suggest that the boundary will become increasingly displaced from the strongest mid-level winds and associated vertical shear. Isolated severe storms also appear possible in the vicinity of a deepening lee cyclone over the central High Plains.
### Days 7-8/Saturday and Sunday
The ensemble mean solutions indicate some potential for mid-level troughing to develop from the northern Rockies into northern Plains next weekend, which is supported by a number of the deterministic models. At the surface, there are indications that a frontal system may stretch from the upper Midwest or Great Lakes into central High Plains, where some severe-weather threat could develop.
