THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS THIS EVENING ACROSS PORTIONS OF THE SOUTHERN HIGH PLAINS

### SUMMARY

A couple of strong thunderstorms may continue to pose at least some risk for severe weather through mid to late evening across parts of the southern high plains.

01Z Update

A subtle short wave impulse digging across the Sangre de Cristo Mountains/Raton Mesa vicinity appeared to provide support for the ongoing cluster of thunderstorms now overspreading the New Mexico/Texas state border vicinity, near and northwest of Clovis. Some discrete thunderstorm development persists southwest of Clovis, and to the north/northwest of Roswell, which could pose a risk for severe hail another hour or two. Otherwise, updraft inflow into the primary cluster already appears to be coming characterized by less instability, based on latest mesoanalysis and convective trends. As this continues, convection appears likely to weaken further with diminishing potential to produce strong to severe surface gusts through 02-03Z.

Farther north, convergence near a weak surface low to the north-northeast of the Raton Mesa vicinity finally appears to be supporting the initiation of isolated thunderstorm development near Springfield, CO. In the presence of steep-lapse rates, low-level moistening appears to have become supportive of CAPE up to 1000 J/kg. Beneath 30-35 kt northwesterly winds around 500 mb, shear appears to conducive to the evolution of a supercell which could persist for an hour or two this evening, before acquiring more stable inflow while tending to propagate southeastward.

Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1228 PM CDT Mon Jun 15 2026

Valid 161200Z - 171200Z

THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FOR PORTIONS OF THE NORTHERN PLAINS INTO THE UPPER MIDWEST…THE GREAT LAKES TO THE CENTRAL PLAINS…AND THE WESTERN/CENTRAL GULF COAST.

### SUMMARY

Isolated to scattered strong to severe thunderstorms are possible Tuesday afternoon and evening across parts of the Midwest into Lower Michigan. Additional strong to severe storms are possible across the northern Plains into the Upper Midwest Tuesday night.

Synopsis

A belt of moderate to strong mid-level flow will extend from the Northwest to the northern Plains and the Midwest and to the Mid-Atlantic on Tuesday. Within this flow, a mid-level shortwave trough will move through the Great Lakes. An additional, stronger shortwave trough will amplify across the northern Plains toward the end of the period. A weak surface low will move through the northern Great Lakes through the day and weaken while an associated cold front moves across the Midwest and eventually stalls toward the end of the period. A stronger surface low will develop across the northern Plains Tuesday night and will be located somewhere near eastern South Dakota by the end of the period.

Midwest to the Central Plains

Strengthening lower tropospheric flow will transport moisture northward ahead of a cold front tomorrow morning/afternoon with weak to potentially moderate instability expected. An initial line of storms will likely develop on the leading edge of the returning moisture in a more well-mixed and uncapped environment. This activity will likely stay sub-severe, but a few isolated damaging wind gusts will be possible given the steep low-level lapse rates and strengthening flow. The greater severe weather potential is expected along the cold front during the afternoon where upper 50s to low 60s dewpoints should be present. Cloud-cover from initial activity should limit overall instability (and a more substantial threat), but cooling temperatures aloft should provide adequate instability for strong to severe storms along the front. The strong shear across the region will support the potential for rotating updrafts capable of isolated large hail, damaging wind gusts, and perhaps a tornado. If instability trends increase, an upgrade to Slight Risk (Level 2/5) may be necessary in later outlooks across northern Indiana, southern Michigan and northwest Ohio.

Northern Plains to the Upper Midwest

Tuesday night, as the mid-level trough amplifies across the northern Plains, the frontal zone across the northern Plains will tighten. Instability is forecast to be relatively weak initially, but strong forcing from dCVA across the region, strengthening isentropic ascent due to the strengthening cyclone, and strong shear beneath the 100+ knot 300mb jet streak will provide an environment that supports isolated strong to severe storms along the frontal zone despite the weak instability.

Within this larger marginal risk region, a greater severe threat may exist shortly before 12Z across northern Iowa and vicinity. Here richer 850 moisture, advected by the strengthening low-level jet, will yield greater elevated instability (1500 to 2000 J/kg MUCAPE). This will provide an environment featuring moderate instability and strong shear amid strengthening isentropic ascent.

Gulf Coast

Most guidance shows a MCV developing across northern Mexico/south Texas today, which is already somewhat apparent across the region. This feature is forecast to move into the western Gulf on Tuesday. Strengthening flow associated with this MCV will overspread the Texas and Louisiana Coast tomorrow. A tropical environment will be present with weak mid-level lapse rates. However, this strengthening flow may support an isolated tornado threat from the central Texas Coast to the eastern Louisiana Coast.

Valid 171200Z - 181200Z

THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS OF THE MID-MISSISSIPPI VALLEY INTO INDIANA AND WESTERN OHIO.

### SUMMARY

An all-hazards severe thunderstorm event is expected across portions of the Middle Mississippi Valley into Indiana on Wednesday. Intense thunderstorms may produce swaths of damaging wind, as well as strong tornadoes and very large hail.

Synopsis

A strong mid-level jet will extend from the Northwest to the Ohio Valley. An embedded 75 to 85 knot mid-level shortwave trough will extend from Nebraska into Iowa by Wednesday afternoon. A strong surface cyclone will move from eastern South Dakota to southern Ontario during the period.

Midwest

Elevated supercells will likely be ongoing at the beginning of the period across central/eastern Iowa at the nose of the low-level jet. This cluster will continue to move east-southeast along/north of the warm front through the day. This activity will likely have some hail threat through the day with at least some tornado threat on the southern periphery if any storms can latch onto the warm front. Strong lower tropospheric flow should result in rapid recovery/destabilization in the wake of these morning storms across central/northern Illinois. A very favorable kinematic environment will be in place with 70 knots of mid-level flow and 100+ knots of upper-level flow with a 60+ knot low-level jet. Therefore, any storms which develop within this zone could have a threat for very large hail, and strong tornadoes. Due to this morning convection, there is considerable uncertainty exactly where this most favorable environment may set up and how broad of a region it will be. Notably, strong isentropic ascent is forecast along the frontal zone through the entire period which could result in continued development along the warm frontal zone (more widespread than currently depicted by guidance) and a limited window for recovery in the wake of the morning storms.

Despite these uncertainties, have upgraded severe probabilities to 45% in the region where multiple rounds of severe weather appear most likely. Conceptually, the 12Z RRFS solution matches a reasonable solution with a morning cluster of supercells including a severe supercell on the southern extent. Additional supercells developing along the trailing outflow/warm front during the afternoon, followed by supercells developing along the cold front by late afternoon. Even if storm development north of the warm front is quite extensive during the day, forecast soundings show a Bunkers storm motion parallel to the expected front/outflow orientation. This points toward a favorable environment for one or more supercells to move along the boundary in a favorable tornadic environment.

Widespread storm development is expected along the cold front by late afternoon from southeast Iowa to far eastern Kansas. Very strong instability and moderate to strong shear will support supercells capable of large to very large hail. In addition, strong low-level shear will support the potential for strong tornadoes. There is some question regarding storm mode along the front. Strong forcing would favor more storm interaction and upscale growth, but fast storm motions (40-50 knots) and a Bunkers RM motion nearly perpendicular to the front may support maintenance of supercell mode at least within some areas along the front. This would support a greater tornado threat during the evening from north-central Missouri to central Illinois. If storms do grow more upscale early in the lifecycle, the tornado/hail threat would be reduced, but the threat for significant wind gusts would increase substantially.

Gulf Coast

A Marginal Risk has been added along the Gulf as a tropical airmass moves inland with a strengthening wind field associated with the tropical disturbance identified by the NHC.

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 0257 AM CDT Mon Jun 15 2026

Valid 181200Z - 231200Z

DISCUSSION

Day 4/Thursday – Mid-Atlantic/Northeast

Strong mid/upper level westerly flow will overspread portions of the Ohio Valley into the Northeast as a shortwave trough pivots across Quebec/Ontario and the Northeast U.S. on Thursday. Quite a bit of uncertainty exists regarding severe potential. Early day convection and cloud cover may limited destabilization from the Upper Ohio Valley into parts of the southern Mid-Atlantic and northeast. Additionally, stronger mid/upper level flow will become increasingly displaced to the north from richer boundary-layer moisture and stronger instability. Nevertheless, sufficient overlap of strong flow atop a moist airmass should occur from southern Ohio/eastern KY into the Mid-Atlantic, supporting a risk for severe thunderstorms on Thursday. This area will likely shift some in the coming days as mesoscale details become better resolved.

Days 5-8/Friday-Monday

A surface front will sag southward across the Gulf Coast states, with surface high pressure centered over the Mid-South vicinity on Friday. This should suppress the overall severe risk as richer boundary layer moisture remains confined to TX and the Gulf Coast. On Saturday, northward transport of Gulf moisture across the Plains is expected beneath a building upper ridge. By Sunday, an upper trough over the West may eject eastward into the Plains, resulting in some return of severe thunderstorm potential this weekend, though spread among forecast guidance is quite large and predictability is low late in the forecast period.
