SPC MD 1330MD 1330 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR EASTERN KENTUCKY INTO WESTERN PARTS OF WEST VIRGINIA AND VIRGINIA 
Mesoscale Discussion 1330 NWS Storm Prediction Center Norman OK 1259 PM CDT Fri Jun 26 2026
Areas affected...eastern Kentucky into western parts of West Virginia and Virginia
Concerning...Severe potential...Watch unlikely
Valid 261759Z - 262000Z
Probability of Watch Issuance...20 percent
SUMMARY...The potential for a few damaging wind gusts is expected to increase this evening. Limited areal coverage and magnitude of threat are expected to preclude a watch issuance.
DISCUSSION...Ahead of a well-defined MCV, a line of showers and thunderstorms has recently intensified in the vicinity of I-75, near Richmond. Daytime heating within the downstream air mass is contributing to destabilization with steep low-level lapse rates and MLCAPE of around 1000 J/kg evident in latest objective analysis. As such, expect the ongoing storms to further intensify while moving through eastern KY, potentially into western parts of WV and VA this afternoon. While relatively weak wind fields and resultant vertical shear are expected to limit the potential for an organized cold pool to evolve, locally damaging downburst winds appear possible given the presence of the steep low-level lapse rates.
The anticipated areal coverage and magnitude of the damaging wind threat are currently expected to remain too marginal for a watch issuance.

SPC MD 1331MD 1331 CONCERNING SEVERE POTENTIAL...WATCH POSSIBLE FOR SOUTHEAST KANSAS...NORTHEAST OKLAHOMA...AND SOUTHWEST MISSOURI 
Mesoscale Discussion 1331 NWS Storm Prediction Center Norman OK 0138 PM CDT Fri Jun 26 2026
Areas affected...southeast Kansas...northeast Oklahoma...and southwest Missouri
Concerning...Severe potential...Watch possible
Valid 261838Z - 262045Z
Probability of Watch Issuance...60 percent
SUMMARY...Severe weather potential is expected to increase across the area this afternoon. Large hail up to 1.5-1.75" and severe wind gusts of 60-65 mph appear to be the primary hazards. Convective trends are being monitored for a Severe Thunderstorm Watch.
DISCUSSION...Recent trends in visible satellite indicate deepening cumulus along an outflow boundary from near the Arkansas City to Independence, KS vicinities into southwest MO, north of Joplin. The air mass to the south of the boundary has warmed into the 80s, which, coupled with dewpoints in the low to mid 70s is resulting in MLCAPE of 1500-2500+ J/kg, per latest objective analysis. Large-scale forcing for ascent remains somewhat nebulous with the movement of several MCVs to the east of the region and no apparent upstream disturbances in water vapor imagery. Nonetheless, the presence of modest low-level warm advection observed by the KSGF VWP may be sufficient to support eventual storm development in the vicinity of the outflow boundary.
Area VWPs and forecast soundings suggest deep-layer shear will be on the margins of that supportive of supercell storm modes. That, coupled with only modestly steep mid-level lapse rates, should limit hail size to 1.5-1.75". Damaging wind potential may ultimately be of greater concern owing to the very moist environment and potential for water-loaded downdrafts. A brief tornado is possible given sizable 0-3 km CAPE and ambient vorticity in the vicinity of the boundary. Otherwise, generally modest low-level shear should limit the overall tornado potential.
Convective trends are being monitored for the potential issuance of a Severe Thunderstorm Watch.

SPC MD 1332MD 1332 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR PORTIONS OF THE COASTAL CAROLINAS 
Mesoscale Discussion 1332 NWS Storm Prediction Center Norman OK 0158 PM CDT Fri Jun 26 2026
Areas affected...portions of the coastal Carolinas
Concerning...Severe potential...Watch unlikely
Valid 261858Z - 262130Z
Probability of Watch Issuance...20 percent
SUMMARY...A damaging gust or two is possible this afternoon across portions of the coastal Carolinas. A watch is not anticipated.
DISCUSSION...A seasonably moist air mass is in place across portions of the eastern Carolinas, where convective temperatures have been reached, resulting in scattered thunderstorms ongoing this afternoon. The KLTX VWP shows generally weak flow, which correlates with the single- and multicell modes apparent on radar. Due to the high precipitable water values (>2 in) in place across the region, water loading in downdrafts may be enough for some damaging gusts across the region. Additionally, storms may cluster with time, and this may slightly increase the threat for damaging gusts. However, this threat is still expected to be fairly sporadic, and therefore a watch is not expected at this time.

SPC MD 1333MD 1333 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR CENTRAL VIRGINIA INTO THE DELMARVA 
Mesoscale Discussion 1333 NWS Storm Prediction Center Norman OK 0237 PM CDT Fri Jun 26 2026
Areas affected...central Virginia into the Delmarva
Concerning...Severe potential...Watch unlikely
Valid 261937Z - 262130Z
Probability of Watch Issuance...20 percent
SUMMARY...The potential for locally damaging wind gusts is expected to increase across the discussion area this afternoon into early evening. The areal coverage and magnitude of the threat are expected to remain too limited for a watch consideration.
DISCUSSION...Recent radar trends indicate gradually strengthening storms along the Blue Ridge Mountains in northern VA with additional storms noted in southeast WV. East of the high terrain, a relatively warm and moist air mass is present with steep low-level lapse rates and MLCAPE of around 1000 J/kg indicated in latest objective analyses. The presence of a westerly, deep-layer wind field should support the eastward movement of storms across the discussion area with the absence of appreciable forcing for ascent potentially limiting overall storm coverage.
The KRLX and KLWX VWPs indicate 30-35 kt winds above 5 km, which are boosting vertical shear generally along and north of that latitude. That modest shear enhancement may contribute to some briefly organized storms capable of locally damaging wind gusts. Relatively warm mid-level temperatures and resultant poor lapse rates should limit large hail potential.
Given the expected isolated nature of the threat, a watch is not anticipated.

SPC Day 2 Fire Weather OutlookSPC Day 2 Fire Weather Outlook  Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0230 PM CDT Fri Jun 26 2026
Valid 271200Z - 281200Z
...EXTREMELY CRITICAL FIRE WEATHER AREA FOR PORTIONS OF WESTERN COLORADO AND EASTERN UTAH INTO THE FOUR CORNERS REGION... ...CRITICAL FIRE WEATHER AREA FOR MUCH OF NEVADA...NORTHERN ARIZONA...NORTHWESTERN NEW MEXICO...CENTRAL/SOUTHERN UTAH...SOUTHERN WYOMING...AND WESTERN COLORADO...
***Dangerous fire weather conditions are expected on Day 2/Saturday across the Four Corners into portions of the Colorado Plateau***
...Afternoon Update... An Extremely Critical risk area was introduced where guidance depicts an overlap of sustained 25-35 mph southwesterly winds and less than 10% RH on Day 2/Saturday. Despite some recent rainfall across the West Slope, appreciable precipitation was not common, and rather quite localized. Widespread 80-95th percentile ERCs and recently receptive fuels will be conducive to rapid spread/fire growth on existing wildfires and any new ignitions. Furthermore, isolated dry thunderstorms on Day 1/Friday present additional concerns for potential lightning holdovers to emerge as several days of hot, dry and windy conditions ensue. An extended burning period is expected (10+ hours for some locations) with poor overnight humidity recoveries and residual gusty winds leading into another day of critical fire weather conditions (see the Day 3-8 Fire Weather Outlook).
The rest of the forecast remains on track, see the previous discussion for more information.
..Elizalde-Garcia.. 06/26/2026
.PREV DISCUSSION... /ISSUED 0302 AM CDT Fri Jun 26 2026/
...Synopsis... A seasonably strong mid-level trough will continue to dig into the western CONUS on D2/Saturday, with an attendant mid-level jet overspreading much of the Upper Colorado River Basin. This will continue to support a robust fire weather pattern across an expansive portion of the Great Basin and Southwest through the weekend.
...Great Basin/Southwest... As the mid-level jet associated with the digging mid-level trough shifts eastward into the Upper Colorado River Valley, a corridor of stronger, sustained surface winds (25-30 mph) will expand from southeastern Nevada into the Colorado Plateau and overlap with very low RH values of 10-15%. Exacerbated by dry, windy conditions on D1/Friday, fuels will be very receptive, with ERCs already noted in the 80-90+ percentiles. These conditions will promote an extended period of critical fire weather conditions from southeastern Nevada into the Upper Colorado River Basin and southern Wyoming. Localized extremely critical wind/RH conditions are possible, particularly across southeastern Utah and perhaps into southwestern Colorado where latest high-res guidance suggests that the best overlap of sustained southwesterly winds approaching 30 mph and very low RH near 10% may occur. Pockets of fuels in this region are also noted to be at or above the 95th percentile. A broader area of elevated wind/RH conditions are expected across adjacent areas of the Great Basin/Southwest where sustained winds of 15-25 mph are forecast to overlap dry fuels and RH values of 10-20%.
The primary change with this outlook was to expand the Critical highlights into north central Colorado based on the latest high-res guidance. Consideration was given to the addition of a targeted Extremely Critical area; however, some uncertainty remains regarding the duration of overlap between sustained winds exceeding 30 mph and RH values dropping below 10%. A portion of the Elevated highlights were also trimmed across central Wyoming and the foothills of northern Colorado owing to recent rainfall.

...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS OF NORTH DAKOTA AND THE UPPER MIDWEST...
...SUMMARY... Severe thunderstorms are possible from the northern Plains into parts of the Upper Midwest on Sunday. Large hail and severe winds are the primary hazards.
...Synopsis...
The western U.S. upper trough will deepen and persist over that region on Sunday. Meanwhile, upper ridging will intensify over the Midwest into the South, while a shortwave upper trough moves from the Ohio Valley to the southern Mid-Atlantic region. At the surface, some uncertainty persists with regards to the location of lee surface low development in the central or northern Plains. The NAM appears to be an outlier compared to the ECMWF/GFS and the AI versions thereof. This will be important for where the best corridor of severe thunderstorm potential develops on Sunday afternoon/evening. Further east, a surface front will sag southward across the Upper OH Valley and portions of the Mid-Atlantic. Between these surface boundaries, a seasonally very moist airmass will exist across at least eastern portions of the Plains to the MS Valley and the southern Mid-Atlantic.
...Northern Plains/Upper Midwest vicinity...
The forecast for Sunday is highly uncertain. Forecast guidance suggests a shortwave impulse and/or MCV will move across northern MN during the afternoon/evening. This area will be beneath the upper ridge axis and could be capped. However, a very moist airmass will be in place beneath steep midlevel lapse rates. Furthermore, a strong southerly low-level jet is expected to focus from the central Plains to the Upper MS Valley during the evening/nighttime hours. If storms can develop and become near-surface based, potential for damaging wind gusts and large hail will be possible. This scenario is generally supported by the RRFS and GSL MPAS, though location/timing varies.
Forecast guidance develops additional areas of convection across portions of western NE/central SD into ND on the western periphery of stronger capping and near the surface trough/dryline within the gradient of stronger instability. This scenario is uncertain, both regarding storm development, and if storms occur, whether or not they will be surface-based. However, if storms do develop, an intense low-level jet within the strongly unstable airmass during the evening/overnight hours could support damaging wind potential. The Marginal risk (level 1 of 5) has been adjusted to reflect this conditional risk.
...Southern Mid-Atlantic...
Forecast guidance suggests an MCV will move across the central Appalachians into parts of VA/NC on Sunday. Deep-layer flow is not expected to be particularly strong, but this feature could locally enhanced vertical shear, with some guidance showing effective shear magnitudes up to 25 kt are possible. A seasonally very moist airmass will reside east of the higher terrain across southeast VA into the eastern Carolinas, supporting moderate destabilization as strong daytime heating occurs. Thunderstorms will pose an isolated damaging wind risk into early evening.

...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS OF THE NORTHERN HIGH PLAINS...
...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS SOUTHEAST VA AND EASTERN NC...
...SUMMARY... Severe storms are likely across portions of eastern Montana and western/central North Dakota on Saturday. Severe storms will also be possible from the Mid-Mississippi Valley to Virginia and the Carolinas, as well as portions of the southern High Plains.
...Synopsis...
An upper low and attendant large-scale upper trough will persist across the western U.S. on Saturday. Further east, upper ridging over the Plains is forecast to shift east toward the Upper Midwest and Mid-MS Valley by Sunday morning. Quasi-zonal/weak upper troughing is expected to persist across the eastern U.S. Within this large-scale regime, several shortwave impulses and embedded MCVs are expected to drive severe thunderstorm potential across multiple areas on Saturday. A lead upper shortwave trough is expected to eject from the eastern Great Basin through the northern High Plains. A series of MCVs will move from the Ozark Plateau to the OH/TN Valleys, while another MCV and/or surface trough impacts thunderstorm potential across the Mid-Atlantic/Piedmont. Finally, another upper shortwave impulse could emerge across the central Plains into the Mid-MO/Mid-MS Valleys.
...Northern Rockies into the Northern Plains...
A midlevel jet streak will overspread parts of the Great Basin into the northern Plains, characterized by 50-60 kt southwesterly 500 mb flow. Cooling aloft is also forecast and will result in a plume of steep midlevel lapse rates. Surface low pressure is forecast to deepen across northeast WY/western SD through evening. This will support northward transport of low to mid 60s F dewpoints into eastern MT/ND/SD. This will result in a narrow corridor of moderate to strong instability. Capping will increase with eastward extent as a result of midlevel height rises/warming aloft, which should confine the eastward extent of severe potential.
As large-scale ascent increasing during the afternoon, convection is expected to develop across the higher terrain of northern UT/ID into WY. This initial activity will pose a risk for strong wind gusts and isolated hail given strong deep-layer flow, steep midlevel lapse rates, and a well mixed boundary layer. Additional convection is expected to develop near the Big Horns and Beartooth/Absaroka ranges. As this activity develops northeast into better low-level moisture and strong instability, large to very large hail potential will increase. With time during the evening, a southerly low-level jet will increase across the Dakotas. Upscale growth is possible as convection moves toward the terminus of the low-level jet and as sufficient clustering/cold pool development occurs. If this convective evolution unfolds, a swath of damaging wind gusts will be possible, mainly across eastern MT into western ND.
...Mid-Atlantic...
Ongoing convection and cloudiness will likely hinder daytime destabilization. Nevertheless, several shortwave impulses will move across the region along with 25-30 kt westerly midlevel flow. Isolated strong storms may produce gusty winds. The Slight risk (level 2 of 5) has been confined to areas nearer the coast where instability will be greatest.
...Southern High Plains...
A surface trough/dryline will extend south/southwest from western KS to southwest TX. A moist airmass will exist east of this boundary with hot temperatures forecast along and just behind the boundary. Moderate to strong destabilization will occur near the boundary in a narrow corridor, confined by stronger capping to the east across much of OK/KS/central TX. However, isolated to widely scattered storms are expected to develop during peak heating to early evening. Vertically veering wind profiles with up to 25 kt effective shear magnitudes suggest organized updrafts and high-based transient supercell structures are possible. Given a deeply mixed boundary layer, strong gusts will be possible. Organized updrafts that can be maintained also will pose a risk of large hail given very steep midlevel lapse rates and somewhat elongated hodographs.
...Ozarks to TN Valley vicinity...
Storms are forecast to be ongoing Saturday morning across southwest MO. This activity could pose a marginal wind/hail risk initially. Additional development is expected from southern IL/southeast MO into KY/TN by late morning and spread east through the afternoon as an MCV moves across the region. While deep layer flow will not be impressive, the MCV could locally enhanced vertical shear. Thunderstorm clusters will mainly pose a risk for damaging winds as they track across moisture-rich and moderately unstable airmass.
...Northeast CO/Western NE into central SD...
Convection may develop during the late afternoon along the surface trough/dryline. Rich boundary layer moisture beneath steep lapse rates will support strong destabilization. This corridor will remain rather confined given rising midlevel heights and capping to the east. Any storms that develop will have potential for strong outflow gusts and large hail.
...Mid-MO Valley vicinity...
It is uncertain if convection will develop across this area, or if it does - will it be surface-based, resulting in a rather conditional severe risk. If storms can develop, an all-hazards severe risk would be possible given a surface warm front lifting north across the region amid ample moisture/instability and supercell wind profiles. Given the conditional nature of the risk, particularly due to capping, will maintain low severe probabilities.
