THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS FOR WESTERN KANSAS

### THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS SURROUNDING THE ENHANCED RISK AND OVER THE UPPER GREAT LAKES AND PARTS OF THE NORTHEAST

### SUMMARY

Scattered severe thunderstorms are probable over parts of the central High Plains, with severe wind gusts (60 to 85 mph) being the primary hazard during the late afternoon and evening.

Synopsis

Water-vapor imagery this morning shows a mid- to upper-level low near the ND/Canadian border and a weak disturbance cresting a mid-level ridge over southeastern ON and moving towards NY. Downstream of a mid-level trough over the Southwest, a couple of weak mid-level vorticity maxima over the southern and central High Plains will slowly migrate northeast around the periphery of a mid-level anticyclone centered over TN. A front will push east across parts of the Upper Midwest and extend southwestward into the central High Plains near a weak low. A weak lee trough/dryline will focus storm development from western KS southward into the southern High Plains.

Southern/Central High Plains

Perhaps associated with a weak disturbance, scattered thunderstorms are forecast later this afternoon over the High Plains on the western rim of richer low-level moisture and strong insolation. Model guidance shows considerable erosion of the capping layer by mid afternoon with MLCAPE ranging from 1500 J/kg over the TX South Plains to 3500 J/kg over western KS. Initially higher-based convection will gradually move east into richer moisture and promote larger thunderstorm cores and increased potential for storm clusters to develop. Large hail will be possible with any supercell activity (i.e., most probable from the northern TX Panhandle into KS; 25-40 kt effective shear). However, very steep surface to 300-mb lapse rates will favor strong evaporative cooling with the more intense cores. Ample deep-layer shear for organized storms but veering/backing of flow with height will aid in storm outflow aggregating as linear clusters become the primary storm mode with time. These organized but linear clusters will likely be efficient in promoting severe wind gusts (60-85 mph) during the early evening, coincident with a strengthening LLJ and WAA before this threat wanes by late evening. Weaker deep-layer shear farther south in the southern High Plains will likely limit both storm organization and overall coverage of the wind risk.

Upper Midwest/Great Lakes

An ongoing area of showers and isolated thunderstorms over the upper MS Valley will likely translate east-northeast today in conjunction with a convectively augmented mid-level disturbance over southern MN this morning. Ahead of this activity, a fetch of very rich moisture will be maintained within south-southwesterly low-level flow. As the boundary layer destabilizes ahead of this disturbance, additional storms are forecast to develop later today within a very to extremely unstable airmass. Ample tropospheric flow will support organized storms, including supercells capable primarily of a hail/wind risk and perhaps a tornado. By late evening, strengthening WAA across NE and the mid MO Valley implies widely scattered storms developing during the mid-late evening, with this activity shifting northeast during the overnight. Isolated hail/wind are the main threats with the stronger storms.

Northeast

A belt of 30-40 kt 500-mb northwesterly flow will reside across the Northeast today. There is uncertainty regarding boundary layer destabilization over portions of this region. Nonetheless, weak to moderate destabilization is progged by model guidance with isolated to scattered storms developing by early afternoon. A couple of short-lived supercells are possible before one or more clusters/bowing segments develop and spread south and eastward with damaging wind potential.

Southeastern US

Located to the south of an upper high centered over the OH/TN Valley, a very moist air mass will be present across much of the region. Strong heating will yield moderate buoyancy by early afternoon. Forecast soundings depict around 20-kt effective shear which will aid in minor multicellular organization. Localized 50-60 mph gusts capable of isolated wind damage will probably accompany the stronger storms.

THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM THE MID-MISSOURI VALLEY INTO CENTRAL WISCONSIN

### SUMMARY

Isolated to scattered strong to severe storms will again be possible from the central Plains into the Upper Midwest as well the Northeast on Wednesday. Severe wind gusts and large hail are the main concerns.

Mid-Missouri Valley into central Wisconsin

Models are in general agreement that a cluster/MCS will be ongoing in the eastern South Dakota/southern Minnesota vicinity early Wednesday morning. There is at least some potential for damaging surface gusts with this activity. Further intensification could also occur as the airmass destabilizes in parts of Wisconsin into the afternoon. However the early day activity evolves, an outflow boundary from this activity will serve as a focus for additional afternoon thunderstorms. 70+ F dewpoints to the south of the boundary will again promote strong to locally extreme buoyancy. Moderate to strong mid-level winds on the southern flank of the upper trough in Canada will allow for 40-55 kt of effective shear near the surface boundary. Initial supercells will be capable of large to isolated very large (around 2-2.5 in.) hail and perhaps a tornado or two. Given the instability, strong downdrafts will likely lead to upscale growth relatively quickly. The risk for severe/damaging winds will become the primary hazard with time, particularly if an MCS can develop. A Slight Risk has been added to cover both potential scenarios.

Northeast

The forecast continues to be uncertain given the nebulous forcing for ascent. Nonetheless, substantial buoyancy will be in place across the region (3000-5000 J/kg MLCAPE). Effective shear of 35-40 kt will promote some storm organization. Model guidance shows variable solutions from more isolated cellular activity to a cluster moving southeastward out of Canada. Given the low confidence in placing more organized activity, a Marginal Risk will be maintained for now. Damaging winds and isolated large hail will be possible.

Central High Plains

Thunderstorm development is expected within the lee trough during the afternoon. A deeply-mixed boundary layer will promote potential for severe winds especially if any clustering can occur. Shear will be modest and severe coverage is expected to be isolated.

Southeast

Strong buoyancy will be in place during the afternoon given rich moisture (70+ F dewpoints). Shear will be quite weak with some minor enhancement in the lower Mississippi Valley. Models do show some potential for clustering, but the location is quite variable. Lack of even subtle features to focus convection keeps confidence in a more organized damaging wind threat low.

THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM THE BLACK HILLS VICINITY INTO PARTS OF THE MIDWEST

### SUMMARY

Strong to severe storms will be possible from the northern Plains into the Midwest and Great Lakes regions on Thursday. Isolated strong to severe storms may also occur in the Tennessee Valley/Southeast as well as parts of the Northeast.

Synopsis

Upper ridging will continue in the East with broad cyclonic flow in the West. Embedded shortwave troughs will likely impact the northern Plains. Another shortwave trough embedded within northwesterly flow aloft will move into parts of the Northeast. A stalled surface boundary will be present from the northern High Plains into the Upper Midwest with a lee trough/weak surface low developing in the High Plains.

Black Hills into Iowa/Minnesota

A subtle shortwave trough is evident in model guidance. This feature will move into Wyoming/Montana and eventually the western Dakotas. Convection appears likely to develop within the higher terrain (Big Horns/Black Hills) and move into an airmass with increasingly rich low-level moisture to the east. Convection should be able to organize along the surface boundary with around 40 kt of effective shear parallel to the boundary itself. Additional convection is also possible along the stationary front as low-level warm advection increases. Though there is some variability in where any eventual MCS will propagate, there is enough confidence to include a 15% severe probability area that encompasses the envelope of potential tracks. The environment would support significant hail with supercells and significant winds with an organized MCS.

Northeast

Ahead of a cold front attendant from a surface low in Quebec, convection will be possible during the afternoon. The timing of the convection, and thus the available buoyancy, is not entirely certain. Damaging wind gusts and large hail would be possible.

Tennessee Valley into Southeast

A subtle easterly wave rotating around the upper anticyclone will promote afternoon convection within a very moist and unstable airmass. Given the mid-level lapse rates will fairly steep, storms will likely be capable of damaging downburst winds despite weak shear.

Note on Medium Range Outlooks

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.

When no specific risk areas are shown, you might see one of these phrases:

Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0338 AM CDT Tue Jun 30 2026

Valid 031200Z - 081200Z

DISCUSSION

Upper-level flow is expected to become more zonal across the CONUS this Friday. The upper ridge within the East will lose amplitude and develop westward and amplify once again into early next week. The exact structure of the upper ridge does vary within model guidance. At the surface, a mostly stationary boundary will continue to be modified/reinforced by convection occurring along/near it on preceding days. As the upper ridge builds in the West, this boundary will likely get pushed farther south within the areas east of the Mississippi by the developing surface high in the Upper Midwest/Great Lakes. Moisture will then be transported farther north/west in the Plains/High Plains beginning sometime this weekend. The general theme for the extended forecast will be where subtle shortwaves/MCVs will propagate and spur convection along the boundary.

For Friday, another MCS is possible along the surface boundary similar to D3/Thursday. Uncertainty in how Thursday's convection will impact the location of the boundary and most favorable environment reduces confidence on where the greatest severe threat will be. Into the weekend and early next week, some severe threat is possible in parts of the eastern CONUS in association with MCV from convection in the Plains/Midwest. Additional severe storms could occur as northwesterly flow aloft develops in the High Plains. There are still enough differences in the upper-level pattern between medium range guidance that predictability of any higher threat corridors is low.
