THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM NORTH GEORGIA INTO SOUTHERN VIRGINIA AND ACROSS THE DAKOTAS INTO WESTERN MINNESOTA

### SUMMARY

Severe thunderstorms capable of damaging winds will be possible from parts of north Georgia, across the Carolinas, and into southern Virginia this afternoon. Additional severe thunderstorms capable of damaging winds and large hail will be possible this afternoon and evening across parts of the Dakotas and western Minnesota.

Synopsis

The base-state mid-level pattern today will feature a western US ridge and eastern US trough, with a weak closed low over the northeast Gulf. Within this background flow field, a short-wave trough will be exiting the Northeast US and a closed low across the Canadian Prairies will crest the western ridge before digging southeast late in the day toward the Upper Midwest.

At the surface, a large anticyclone will settle into the Great Lakes region during the day. On the periphery of this anticyclone, a cold front will be draped from coastal Virginia to the west-southwest, before arcing northwest into the Mid-Mississippi Valley and then into the Upper Midwest. This front will sag south across the eastern US, while beginning to lift north and east across the Mississippi Valley and Upper-Midwest. The front will act to delineate a very warm/hot and moist airmass to the south and west from a cooler/dryer airmass to the north and east.

### Georgia into southern Virginia and the greater Southeast

To the south of the advancing surface front, temperatures will warm into the low-to-mid-90Fs from northern Georgia into southern Virginia. At the same time, surface dewpoints of the upper-60Fs and low-70Fs will be maintained. The result will be an strongly unstable environment with HREF ensemble mean MUCAPE between 1500-2000 J/kg across the region. Forecast soundings show precipitable water greater than 1.75 inches across much of the area, with a band of precipitable water in excess of 2 inches. This, coupled with steep sub-cloud layer lapse rates (approaching 8 C/km) which will support wind damage potential with any sustained thunderstorm updraft.

Surrounding this area, more scattered thunderstorm development is expected within the moist and unstable environment. At this time, it appears a corridor of higher likelihood for thunderstorm development will extend from southeast Louisiana northeast toward northern Georgia. This increased thunderstorm activity appears to be associated with a band of modest convergence in the 850-700 millibar layer to the north of a weak low across the northeast Gulf. Damaging wind gusts will be possible with some of these storms.

Another potential area of damaging wind gusts will be across north-central Florida into far south-central Georgia. Here, HREF guidance shows an east-northeast expanding band of thunderstorms emanating from the low over the northeast Gulf.

### Dakotas into western Montana

Temperatures are expected to warm into the upper-90Fs to the low-100Fs during the afternoon to the east of a low-level trough axis developing in the lee of the Rockies in the northern High Plains. To the east of this trough axis, HREF ensemble mean dewpoints in the mid-to-upper-60Fs will combine with those hot afternoon temperatures to support a very unstable environment, with HREF ensemble mean MUCAPE values between 1500-2000 J/kg across the Dakotas and individual members considerably higher (3000-4000 J/kg).

Scattered thunderstorms are expected to develop across the Dakotas by mid afternoon as convective temperatures are approached and modest height falls overspread the area. Long, straight hodographs and effective-layer shear around 40-knots will support supercellular structures, including storm splits, early in the thunderstorm convective life cycle. Large hail, potentially in excess of 2 inches, will be possible with these initial storms. However, dry sub-cloud layers and low-level lapse rates around 9 C/km will support strong convective outflows that will tend to favor upscale growth, especially in regions where storm splits interact with one another. One or more convective clusters will move east-southeast during the late afternoon and evening continuing the threat for damaging winds, before eventually weakening overnight.

Outlook for Monday, July 20

Outlook Summary

Severe thunderstorms are probable across portions of the Upper Midwest and Great Lakes vicinity on Monday. Swaths of damaging winds will be the most likely hazard, with isolated large hail as well. Isolated strong to damaging gusts may occur over parts of the Carolinas.

Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1234 AM CDT Sun Jul 19 2026

Valid 201200Z - 211200Z

THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROSS FAR SOUTHEAST MN…NORTHEAST IA…NORTHERN IL…WI…AND THE UPPER PENINSULA OF MICHIGAN

### SUMMARY

Severe thunderstorms are probable across portions of the Upper Midwest and Great Lakes vicinity on Monday. Swaths of damaging winds will be the most likely hazard, with isolated large hail as well. Isolated strong to damaging gusts may occur over parts of the Carolinas.

Upper Midwest/Great Lakes

An upper shortwave trough initially over the northern Plains early Monday will strengthen as it progresses east/southeast over the Upper Midwest/Great Lakes. As this occurs, mid/upper west/northwesterly flow will intensify, with most guidance showing 50-60 kt at 500 mb, and 850-700 mb potentially increasing to 40+ kt. At the surface, low pressure will deepen as it shifts east across Ontario and the northern Great Lakes. A trailing cold front will sweep east/southeast during the afternoon and evening, becoming positioned from northern Lower MI to northern MO by Tuesday morning. Ahead of the front, a very moist airmass characterized by 70s dewpoints will be in place. This moisture will modestly decrease east of Lake MI. Within the moist axis, strong to extreme instability is forecast (particularly from IA into WI).

Some uncertainty remains concerning placement and extent of potential ongoing convection early Monday, and will depend on evolution of storms overnight in the Day 1/Sunday period, and the timing of a possible lead shortwave impulse. Morning convection could have implications for where corridors of greater severe potential will develop during the afternoon/evening. Nevertheless, the region will experience strong warm advection ahead of the cold front, and airmass recovery is likely.

Supercell wind profiles are evident in forecast soundings. A favorable thermodynamic/kinematic environment could support initial supercells capable of all severe hazards, and possibly significant severe. However, given the progressive nature of the upper trough and surface cold front, along with intensifying 850 mb flow by late afternoon/evening, upscale growth into one or more bowing MCSs appears possible. Significant damaging wind potential will increase with a transition to linear storm mode. The south and east extent of severe potential is also uncertain, but if a mature MCS develops during the evening, it seems reasonable the severe wind risk could persist into portions of Lower MI, northern IN and northwest OH overnight.

North Carolina vicinity

Weak northwest flow aloft will persist across the Mid-Atlantic on Monday. Modest lee troughing across the Piedmont will allow a surface front to lift north across part of NC into VA, and spreading rich boundary layer moisture across the region. Strong heating will result in moderate destabilization and scattered thunderstorms will develop during the afternoon. Deep-layer flow will remain modest, but sufficient clustering, high PW values, and steep low-level lapse rates will support isolated damaging wind potential.

THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROSS THE OHIO VALLEY

### SUMMARY

Numerous severe thunderstorms are expected across a broad region from the Ohio Valley into the Mid-Atlantic and Northeast on Tuesday. All severe hazards are possible, but swaths of damaging wind gusts should be the primary severe risk Tuesday afternoon into the nighttime hours.

Ohio Valley to the Mid-Atlantic/Northeast

A vigorous upper trough will spread across the region on Tuesday. A broad area of strong deep-layer flow, especially by July standards, will overlap a very moist airmass ahead of an eastward progressing surface cold front. Widespread dewpoints in the upper 60s to low 70s are expected. While some uncertainty exists regarding potential morning convection in the form of a remnant MCS from the Day 2/Monday period across parts of MI/IN/OH, pockets of stronger heating should occur, and given rich moisture/continuous warm advection ahead of the surface front, strong destabilization is forecast. While boundary layer moisture will begin the day somewhat muted across parts of the Northeast, strong warm advection and increasing southerly low-level flow across the Mid-Atlantic into the Northeast will also result in northward transport of richer boundary layer moisture through evening. While instability may be somewhat less further east into the Mid-Atlantic/Northeast, strong deep-layer flow will envelop this region as well.

Supercell wind profiles are evident across the broad warm sector, with 40+ kt westerly flow common above 850 mb. Where supercells can develop and be maintained, all severe hazards will be possible. However, given the strong flow field, and the progressive trough and surface front, one or more bowing segments will quickly develop and spread eastward. Swaths of damaging winds will be the primary concern during the afternoon and into the nighttime hours.

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.

Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0246 AM CDT Sun Jul 19 2026

Valid 221200Z - 271200Z

DISCUSSION

Day 4/Wed - Mid-Atlantic/Carolinas

An upper trough will lift northeast across the region on Wednesday. At the surface, a cold front will be oriented from roughly the Hudson Valley to the central Appalachians at the beginning of the period. Within a zone of strong warm advection ahead of the surface front, widespread showers and thunderstorm may be ongoing across parts of the Mid-Atlantic and Northeast, resulting in uncertainty regarding northward extent of severe potential. For now, the 15 percent severe probability has been confined to portions of the southern Mid-Atlantic and Carolinas ahead of the surface trough/cold front. A very moist airmass will be in place across the region, and 25-35 kt effective shear magnitudes are forecast. Thunderstorm clusters or linear bands are expected to move across the region through evening, posing mainly a risk for damaging winds.

Days 5-8/Thu-Sun

Severe potential is expected to be lower late in the week into the weekend. An upper trough will persist over the eastern U.S., but deep-layer flow will be weak. Further west, the subtropical high will intensify over the Plains and into the Four Corners vicinity while the associated amplified upper ridge persists northward into the Canadian Prairies. As boundary layer moisture spreads northward beneath the upper ridge, some severe potential could develop each day across parts of the High Plains. However, this will largely be driven by mesoscale processes not well resolved at longer lead times. Overall, the intense upper ridge should largely suppress greater severe potential.
