Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1259 AM CDT Sat Apr 04 2026 Valid 041200Z - 051200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS SOUTHEAST LOWER MICHIGAN...MUCH OF OHIO...AND PORTIONS OF WESTERN PENNSYLVANIA AND NEW YORK.... ...SUMMARY... Strong-to-severe storms will be possible from eastern Texas northeastward toward the Lower Great Lakes. Sporadic damaging winds will be the most likely severe hazard throughout this corridor, with the greatest likelihood across the Lower Great Lakes. ... Synopsis ... A midlevel trough is forecast to move from the northern Plains into Ontario on Saturday As this happens, a surface low should lift northward from northern Illinois/southern Wisconsin into Ontario as well and a surface cold front will accelerate eastward across the Great Lakes and be approaching the East Coast by Sunday morning. To the southwest, the cold front will not progress as quickly, but should advance south and east through the day. ... Southeast Lower Michigan, Ohio, Western Pennsylvania, and western New York ... As the surface low lifts northward into Canada on Saturday, showers and thunderstorms are expected to be ongoing along and ahead of the trailing composite cold front/convective outflow. At the same time, a surface warm front will lift slowly northward across Lower Michigan. To the south of this front, and ahead of the cold front/outflow, a moist airmass, characterized by low-to-mid 60Fs dewpoints should be in place. Despite the strongest large-scale ascent being displaced to the north and west of the warm sector and weak midlevel lapse rates atop the warm sector, pockets of insolation should be sufficient to destabilize the environment enough to support some convective redevelopment along and ahead of the composite outflow/cold front. Modest instability will combine with seasonably strong low-level wind fields to support a convective wind threat and an isolated tornado threat along the leading edge of any sustained linear segments. ... Tennessee Valley southwest to eastern Texas ... Widespread thunderstorms are expected to be ongoing across the western portions of this area at the start of the forecast period. These thunderstorms will likely be driven by convergence along the east/southeast moving composite cold front/convective outflow boundary, with the exact western edge of any severe threat demarcated by where this boundary is located at the start of the forecast period. Seasonably high precipitable water values should support some threat for strong wind gusts in the most intense thunderstorm cores. These thunderstorms are expected to continue through the day, despite weakening large-scale ascent and vertical wind shear as the midlevel low pulls farther away. Given the seasonably high precipitable water values, modest insolation should support MUCAPE values between 500 and 1000 J/kg (perhaps as high as 1500 J/kg) across portions of Texas, Louisiana, and Mississippi. This may support a re-intensification of ongoing convection which would be capable of sporadic damaging downbursts ..Marsh/Chalmers.. 04/04/2026 Read more

SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0756 PM CDT Fri Apr 03 2026 Valid 040100Z - 041200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM NORTHWEST TEXAS NORTHEAST INTO SOUTHEAST IOWA AND EAST INTO CENTRAL ILLINOIS... ...SUMMARY... Thunderstorms continue to evolve into an extensive line this evening from Iowa to Oklahoma and northwest Texas. Damaging winds, hail, and a couple of tornadoes remain possible through the overnight. ... 01Z Update ... Thunderstorms continue to develop along and ahead of an advancing cold front this evening. These storms should continue to increase in number, growing upscale into an extensive linear MCS from Northwest Texas northeastward into southern Iowa. Despite nocturnal stabilization of the boundary layer, forcing along the cold front, MUCAPE between 1000-2000 J/kg, and sufficient vertical shear should support a continued hail and wind threat into the overnight hours, especially across the southern portion of this area where updrafts appear to be more robust than areas farther north. Given the moist low-levels and a modest uptick in the low-level jet, a couple of tornadoes may still occur as well. Additional thunderstorms have developed eastward along the warm front draped across southern Iowa east across Illinois, Indiana, Ohio, and Pennsylvania. MUCAPE and vertical shear decrease with eastward extent along the warm front, organized thunderstorms within the frontal zone should support an localized hail and wind threat for a few more hours. A tornado or two could also be realized with any discrete/semi-discrete cell that can increase its resonance time in the frontal zone, especially across central Illinois where better instability and vertical shear exist. ..Marsh.. 04/04/2026 Read more

MD 0344 CONCERNING SEVERE POTENTIAL...WATCH POSSIBLE FOR CENTRAL PORTIONS OF ILLINOIS INTO CENTRAL AND NORTHWEST INDIANA
Mesoscale Discussion 0344 NWS Storm Prediction Center Norman OK 0459 PM CDT Fri Apr 03 2026 Areas affected...Central portions of Illinois into central and northwest Indiana Concerning...Severe potential...Watch possible Valid 032159Z - 040000Z Probability of Watch Issuance...60 percent SUMMARY...The severe threat may increase into the evening hours, though the overall intensity and coverage of storms remains uncertain at the moment. DISCUSSION...Multicells and transient supercells persist along an east-to-west oriented baroclinic zone across central IL/IN. These storms are developing amid a moist boundary layer, characterized by upper 60s F dewpoints amid small T/Td spreads, with over 1500 J/kg MLCAPE present. The upper trough is currently displaced relatively far to the west, so shorter term forcing mechanisms are predominantly from stronger surface heating, and the ILX/IND VADs currently depict short and modestly curved hodographs. The current thinking is that storms should remain at their current degree of organization and intensity for at least the next couple of hours. Transient circulations potentially supporting isolated, brief tornadoes is the most immediate threat. A few hours from now, into the evening hours, the gradual approach of the upper trough will support a substantial strengthening of the 850 mb flow (i.e. southerly low-level jet), especially in the 00-06Z time frame. Should discrete, surface based storms persist in this time frame, it is plausible that appreciable strengthening and organization of supercell structures with sustained low-level mesocyclones may be achieved. Such storms may pose a locally greater tornado threat in addition to severe wind/hail. However, such a threat is dependent on storms remaining surface based, with boundary layer stabilization only gradually taking place. As such, uncertainty remains. However, convective trends will continue to be monitored through the evening hours as the low-level jet intensifies. ..Squitieri/Smith.. 04/03/2026 ...Please see www.spc.noaa.gov for graphic product...

MD 0345 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR PORTIONS OF THE TEXAS BIG BEND INTO STOCKTON PLATEAU
Mesoscale Discussion 0345 NWS Storm Prediction Center Norman OK 0501 PM CDT Fri Apr 03 2026 Areas affected...portions of the Texas Big Bend into Stockton Plateau Concerning...Severe potential...Watch unlikely Valid 032201Z - 040000Z Probability of Watch Issuance...20 percent SUMMARY...Isolated supercells forming along a dryline across the Texas Big Bend Region into Stockton Plateau will pose a risk of large/very large hail and severe wind gusts over the next couple of hours. DISCUSSION...Thunderstorm development is ongoing south of Fort Stockton along a trailing dryline. A moderately unstable environment (2000-2500 J/kg MLCAPE) and around 40-50 kts of effective bulk shear will favor supercell development capable of large/very large hail and severe wind gusts. While mid-level lapse rates remain modest (~7 C/km), ample buoyancy within the hail growth zone (300-400 J/kg) coupled with straight, elongated hodographs will support the potential for hail of 2+ inches in diameter with any persistent supercell. Given the displacement of better synoptic-scale forcing well to the north, storm coverage is expected to remain isolated. Thus, watch issuance appears unlikely at this time. A new Severe Thunderstorm Watch may need to be considered, however, should supercells trend towards more scattered coverage with the potential for a longer duration hail threat. ..Chalmers/Smith.. 04/03/2026 ...Please see www.spc.noaa.gov for graphic product...

MD 0346 CONCERNING SEVERE THUNDERSTORM WATCH 93... FOR PORTIONS OF THE TEXAS ROLLING PLAINS INTO CENTRAL OKLAHOMA AND SOUTHEAST KANSAS
Mesoscale Discussion 0346 NWS Storm Prediction Center Norman OK 0605 PM CDT Fri Apr 03 2026 Areas affected...portions of the Texas Rolling Plains into central Oklahoma and southeast Kansas Concerning...Severe Thunderstorm Watch 93... Valid 032305Z - 040100Z The severe weather threat for Severe Thunderstorm Watch 93 continues. SUMMARY...Scattered supercells continue to pose a threat for large/very large hail and damaging wind gusts. A transition to a more linear storm mode and severe wind threat is expected with time. The tornado threat remains conditional on a discrete storm persisting into the evening. DISCUSSION...Latest visible satellite/radar imagery depicts scattered supercells along a cold front/trailing dryline from eastern Kansas southwestward into the Texas Rolling Plains. While storms have struggled to maintain intensity thus far owing to lingering capping, moderate buoyancy (2000-2500+ J/kg MLCAPE) and 40-50 kts of effective bulk shear will continue to support discrete/semi-discrete supercells capable of large/very large hail to 2+ inches in diameter and severe wind gusts. Deep-layer shear vectors are largely oriented parallel to the southeastward progressing cold front, which is expected to favor upscale growth into a more linear storm mode over the next few hours, with a transition to severe wind gusts as the primary hazard. The tornado threat remains conditional on maintaining a discrete storm into the evening hours when a strengthening nocturnal low-level jet will favor increasing low-level shear/hodograph curvature. The greatest potential for discrete storm maintenance appears to be across northwest Texas into southwest Oklahoma in close proximity to a weak surface low located near the cold front/dryline intersection/ ..Chalmers.. 04/03/2026 ...Please see www.spc.noaa.gov for graphic product...

SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0353 PM CDT Fri Apr 03 2026 Valid 051200Z - 111200Z Upper-level ridging will be in place across the western US on Day 3/Sunday with an upper-level trough over the Great Lakes region. Meanwhile, a significant cold front will be moving across the Eastern Seaboard, having left accumulated precipitation across much of the central and eastern US. An incoming trough over the Pacific Northwest will flatten the ridge slightly on Day 5/Tuesday. This will contribute to near-zonal flow across the southern half of the CONUS on Day 6/Wednesday as the incoming trough moves along the Canadian border. Also on Day 6/Wednesday, a cutoff upper-level low approaches the central California coast, contributing to precipitation over the southern half of the western US through Day 8/Friday as it moves inland. ...Day 3/Sunday and Day 4/Monday... A tightened surface pressure gradient will result in sustained south-southwest winds of up to 20 mph over portions of the southern High Plains. This combination of wind with RHs down to 10-15%, supports the introduction of 40% probabilities over this area. ...Day 5/Tuesday and Day 6/Wednesday... One area that the latest guidance leaves out of accumulating precipitation is just east of central and southern Appalachian Mountains. While uncertainty remains among the latest forecast guidance, the potential for offshore flow will be possible early to mid-next week. This area will be watched closely for potential inclusion as the timing of northerly winds and the consistency of preceding precipitation (especially on Day 1/Friday and Day 3/Sunday) becomes more clear. While some potential for critical conditions will exist across portions of the Great Basin and surrounding areas as the upper-level ridge breaks down on Day 5/Tuesday, preceding precipitation and resultant questionably receptive fuels will preclude any probabilities over that area with this issuance. Another day of tightened surface pressure gradient supports south-southwest winds of up to 20 mph and RHs down to 10-15% over portions of the southern High Plains again on Day 6/Wednesday. Much of this region is favored for accumulating precipitation by late next week. ..Stearns.. 04/03/2026 ...Please see www.spc.noaa.gov/fire for graphic product... Read more

Thunderstorms are expected to evolve into an extensive line this evening from Iowa to Oklahoma and northwest Texas, with the primary threats of large hail and damaging winds. A few tornadoes are also possible in any supercells that can form ahead of the line over parts of Iowa, Missouri, and central Illinois. ...20z update KS, MO IA and IL... Scattered thunderstorm development was ongoing this afternoon ahead of a weak surface low an associated cold front over the MO Valley. To the east, a broad and unstable warm sector exists south of a quasi-stationary front extending into eastern MO and IL. Moderate buoyancy and deep-layer shear will support a mix of supercells. Damaging winds and hail remain the most likely near the cold front as it moves eastward with a linear storm modes. A few tornadoes are also possible with more discrete cells and backed surface winds along the warm front farther east. The primary update to the forecast was to remove thunder and severe probabilities behind the cold front, otherwise the severe risk remains as is. ...Southern KS, OK and into TX... Scattered to numerous thunderstorms remain likely this afternoon and evening along the advancing cold front from southern KS, across much of OK and ahead of a dryline into west-central TX. South of the primary upper trough and stronger flow aloft, overall forcing will be weaker. Still, forecast soundings and observation trends show moderate destabilization and sufficient deep-layer shear for supercells and organized clusters/line segments. Hail (some 2+ in) is possible with initial supercells before upscale growth is expected to take place with the surging cold front. A locally more favorable zone for large hail, damaging gusts and a tornado or two may develop across parts of central and southern OK if semi discrete supercells or stronger bowing structures can become organized/maintained this afternoon/evening. ...OH Valley... A moist and unstable air mass will support scattered thunderstorms across the OH valley this afternoon. Isolated damaging gusts are possible with multi-cell storms/clusters amid modest vertical shear. Storms should weaken this evening with the loss of diurnal heating. ..Lyons.. 04/03/2026 .PREV DISCUSSION... /ISSUED 1106 AM CDT Fri Apr 03 2026/ ...MO/IA/IL... Latest surface analysis shows a low over northeast KS. This low will track northeastward across southern IA today, with the associated warm front lifting northward into northern IL. The air mass in the warm sector of the low will be relatively moist and unstable with dewpoints in the lower 60s and afternoon MLCAPE values of 2000 J/kg. Thunderstorms are expected to develop near the surface low in IA, and more widely scattered storms eastward along the warm front. A few supercells are possible across this region, with a concern for tornadoes, large hail, and damaging winds in the most intense cells. ...MO/KS/OK/TX... An extensive line of thunderstorms is expected to form along the cold front this afternoon from western MO into southeast KS and much of OK. Ample low-level moisture and CAPE will be present ahead of the storms, along with sufficient deep-layer shear for rotating/bowing storm structures. Large hail and damaging winds appear to be the main concern, but a tornado or two are also possible. Read more
