SPC 0600Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1248 AM CDT Tue May 19 2026 Valid 201200Z - 211200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS SOUTHERN NEW ENGLAND INTO THE MID-ATLANTIC AND OVER THE SOUTHERN HIGH PLAINS INTO SOUTHWEST TEXAS... ...SUMMARY... Scattered thunderstorm activity across the Mid-Atlantic region Wednesday may pose a risk for severe wind and hail. Large hail will be possible with isolated to widely scattered thunderstorms developing over the southern High Plains into southwest Texas. ...Synopsis... A trough will continue to lift northward into Canada D2/Wednesday, with a cold front extending from the Northeast southward across the southern Ohio Valley into the lower Mississippi Valley and westward into southwestern Texas and eastern New Mexico. Scattered strong to severe storms are expected near the front in the mid Atlantic and near the high terrain of western Texas. ...Mid-Atlantic... Scattered showers and storms are expected along the cold front Wednesday afternoon across portions of the Mid-Atlantic. The downstream air mass will include a narrow plume of weak to moderate instability. Though deep layer shear and mid-level lapse rates will be marginal, steep low level lapse rates will support a few instances of strong to severe winds. ...Southwest Texas and eastern New Mexico... Isolated to widely scattered thunderstorms are expected to develop near the high terrain within the upslope flow regime across western Texas and eastern New Mexico Wednesday afternoon. Forecast soundings depict sufficient deep layer shear to support supercells. Moderate to strong instability and steep low to mid-level lapse rates will support potential for large hail and a few occurrences of severe winds. ..Thornton.. 05/19/2026 Read more

SPC 1200Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1243 AM CDT Tue May 19 2026 Valid 191200Z - 201200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM PARTS OF THE SOUTHERN PLAINS INTO THE MID MISSISSIPPI VALLEY...AND LOWER GREAT LAKES... ...SUMMARY... Widely scattered severe thunderstorms will be possible today from the southern Plains northeastward into the mid Mississippi Valley and lower Great Lakes. Damaging winds and hail will be the primary threats. A greater threat for large hail is expected in the southern High Plains. ...Ozarks/Mid Mississippi and Ohio Valleys/Lower Great Lakes... At mid-levels today, a shortwave trough and an associated 75 to 90 knot jet streak will move northeastward into the upper Mississippi Valley. At the surface, a cold front will advance southeastward through the lower Missouri Valley and Great Lakes. Along and ahead of the front, surface dewpoints will mostly be in the mid to upper 60s F. This will contribute to the development of moderate instability over much of the pre-frontal airmass. Increasing low-level convergence near the front and warming surface temperatures will support scattered thunderstorm development by afternoon. Along much of the front, 0-6 km shear is forecast to be between 25 to 35 knots, suggesting that enough shear will be present for organized storms. The potential for severe wind gusts will be greatest along the leading edge of line segments that form in areas that heat up the most. The severe threat is expected to persist into the evening. ...Southern Plains... A mid-level shortwave trough will move northeastward into the southern High Plains today. Ahead of the trough, a moist and unstable airmass will be located over much of the southern Plains with surface dewpoints the upper 60s and lower 70s F. In response to surface heating, moderate instability will develop over much of the moist sector, with MLCAPE likely peaking in the 3000 to 4000 J/kg range in many areas. Increasing low-level convergence near the front will lead to thunderstorm development during the afternoon. The greatest convective coverage is forecast across west-central and north-central Texas, where low-level flow will be maximized. Ahead of the developing storms, forecast soundings by late afternoon show moderate deep-layer shear and steep mid-level lapse rates. This environment will support a potential for supercells with large hail, mainly with cells in the stronger instability that can remain discrete. A threat for severe wind gusts is also expected, with this threat increasing if a cold pool can organize during the late afternoon or evening. The severe threat could impact parts of the Texas Hill Country and east Texas later in the evening, before the threat becomes more isolated. ..Broyles/Squitieri.. 05/19/2026 Read more

SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1154 PM CDT Mon May 18 2026 Valid 201200Z - 211200Z ...Synopsis... The active and progressive mid-level synoptic pattern responsible for recent critical fire weather across the Southwest and southern High Plains will begin transitioning toward a more quasi-zonal flow regime on Wednesday. Below-normal temperatures and fairly widespread precipitation will overspread of the central and eastern CONUS. This incoming airmass will temporarily dampen the fire weather threat across a broad portion of the country and support a beneficial green-up of herbaceous vegetation in some areas, particularly across the northern CONUS, where fire-slowing vegetation has struggled to emerge this spring. However, dry and breezy conditions remain in place for at least one more day across portions of the Southwest. ...Southwest... Despite the flattening upper-level pattern, a lingering belt of moderate southwesterly flow aloft (30-40 kts near the top of the afternoon boundary layer due to strong diurnal heating) will remain over the Southern Rockies. Sustained southwest winds of 10-20 mph will align with minimum relative humidity values of 10-20%. Thus, an area of Elevated fire weather conditions will exist as this wind/RH overlap coincides with critically dry fuels. ..Stearns.. 05/19/2026 ...Please see www.spc.noaa.gov/fire for graphic product...

SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1153 PM CDT Mon May 18 2026 Valid 191200Z - 201200Z ...Synopsis... A broad mid-level trough will continue to meander over the Intermountain West today, maintaining a tight surface pressure gradient over the Southwest. Deep boundary-layer mixing during the afternoon will allow stronger mid-level flow to transfer to the surface, resulting in widespread breezy conditions. Meanwhile, a dry air mass will remain entrenched over portions of southern Nevada and the Mojave Desert, driving minimum RH values into the single digits and teens with localized areas of elevated wind gusts over receptive, but sub-critically dry fuels. ...Southwest... As daytime heating maximizes this afternoon, deep surface mixing will yield sustained south/southwesterly winds of 15-20 mph. Given the dry antecedent conditions, surface RH will quickly drop to 10-15% across central/southern NM and portions of eastern AZ. Channeling effects within terrain-favored areas, specifically the Middle Rio Grande Valley, will likely produce localized Critical fire weather conditions, where sustained winds may briefly exceed 20 mph alongside RH values near 10-15%. ..Stearns.. 05/19/2026 ...Please see www.spc.noaa.gov/fire for graphic product...

MD 0778 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR PORTIONS OF FAR EASTERN NEBRASKA INTO WESTERN IOWA AND EXTREME SOUTHERN MINNESOTA
Mesoscale Discussion 0778 NWS Storm Prediction Center Norman OK 0510 PM CDT Mon May 18 2026 Areas affected...portions of far eastern Nebraska into western Iowa and extreme southern Minnesota Concerning...Severe potential...Watch unlikely Valid 182210Z - 182345Z Probability of Watch Issuance...20 percent SUMMARY...A couple instances of severe hail may occur with some of the stronger storms. The severe threat is expected to remain isolated. DISCUSSION...Multicells and transient supercell structures have been gradually intensifying within a WAA regime north of the warm front. 21Z mesoanalysis depicts 1000-2000 J/kg of MUCAPE and 35-45 kts of effective bulk shear, suggesting that storms may achieve some degree of organization, with severe hail possible with the stronger, more persistent updrafts. However, storms are tracking into an environment characterized by decreasing buoyancy and shear, putting total severe coverage in question. As such, a WW issuance is not currently anticipated. ..Squitieri/Mosier.. 05/18/2026 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...DMX...FSD...OAX...GID...

MD 0779 CONCERNING TORNADO WATCH 225... FOR FAR NORTHEAST KANSAS...SOUTHEAST NEBRASKA...AND NORTHWEST MISSOURI
Mesoscale Discussion 0779 NWS Storm Prediction Center Norman OK 0545 PM CDT Mon May 18 2026 Areas affected...far northeast Kansas...southeast Nebraska...and northwest Missouri Concerning...Tornado Watch 225... Valid 182245Z - 190045Z The severe weather threat for Tornado Watch 225 continues. SUMMARY...The threat for tornadoes in the next few hours is maximized from northeast Kansas into far southeast Nebraska and northwest Missouri. A couple strong tornadoes are possible. DISCUSSION...Supercells currently extend from the KS/NE border area southwestward into much of northeast KS along the cold front, and, along the warm front from southeast NE into northwest MO. Recent trends have shown better organization and structure to these supercells, with tornadoes confirmed. Most notably, a tornadic supercell was ongoing over Marshall County KS, and, from Holt into Atchison Counties in northwest MO. The environment over this area favors strong tornadoes, with 0-1 km SRH of 200-300 m2/s2, locally higher, and very strong instability. This area near the warm front is where surface winds are backed to southeasterly, and where the low-levels remain sheltered from the deeper boundary layer mixing as opposed to farther south where surface winds exceed 30+ kt. The low-level jet will remain at or above 50 kt through early evening, which will also allow the warm front to push farther into MO and southern IA. While the cold front is more likely to undercut cells south of I-70 in the near term with eventually transition to damaging wind threat, areas across the KS/NE/IA/MO borderland region will continue to experience a threat of strong tornadoes. ..Jewell.. 05/18/2026 ...Please see www.spc.noaa.gov for graphic product...
