SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1127 AM CDT Mon Apr 27 2026 Valid 271700Z - 281200Z ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF EASTERN NEW MEXICO INTO WESTERN TEXAS... Some slight expansion of Critical Highlights were made across central and southeastern NM into far west TX, primarily for wind prone areas in the lee of the Sandia Manzano Mountains and Guadalupe Mountains in southeastern NM and far west TX. A robust 55-65 knot mid-level jet remains over the Southwest and Southern Plains, while current surface analysis shows a trough and associated cold front extending southwestward from a surface low approaching the Upper Midwest. Dry, downslope-enhanced westerly flow corridors of 15-20 mph south of the cold front will support an enhanced fire weather threat across portions eastern NM and western TX through the afternoon. The persistent downslope regime inhibited overnight RH recoveries, with minimum RH reductions of around 10% likely across southeastern NM into far west and northwestern TX by afternoon peak heating. These fire-effective weather conditions and receptive fuels will promote a higher potential for wildfire spread. ..Williams.. 04/27/2026 .PREV DISCUSSION... /ISSUED 0145 AM CDT Mon Apr 27 2026/ ...Synopsis... Elevated to critical fire weather conditions are expected this afternoon across the southern High Plains. Early-morning surface observations show that a very dry air mass resides over the Southwest and southern High Plains with dewpoints in the 15-25 F range for most locations. This air mass resulted in RH minimums generally near 10% yesterday, and with no moisture recovery expected over the next 24-48 hours, similar RH values are anticipated this afternoon. Gradient winds will generally increase to 15-20 mph across the region through late morning and early afternoon before gradually abating by early evening as a surface cyclone drifts towards the MS Valley/Midwest region. Critical conditions appear most likely roughly along the I-40 corridor and downwind of the Sacramento Mountains. Here, residual belts of 20-30 mph low-level flow within the boundary layer will help support sustained winds closer to 20 mph with gusts up to 30-35 mph. Given dry conditions over preceding days and recent new fire activity, fuels will support some degree of fire spread. ...Please see www.spc.noaa.gov/fire for graphic product... Read more

MD 0566 CONCERNING SEVERE THUNDERSTORM WATCH 156...157... FOR CENTRAL MISSOURI
Mesoscale Discussion 0566 NWS Storm Prediction Center Norman OK 0933 AM CDT Mon Apr 27 2026 Areas affected...Central Missouri Concerning...Severe Thunderstorm Watch 156...157... Valid 271433Z - 271630Z The severe weather threat for Severe Thunderstorm Watch 156, 157 continues. SUMMARY...The potential for isolated damaging winds and large hail is expected to continue beyond the scheduled 15z expiration of Severe Thunderstorm Watches 156 and 157. A local extension in time may be required. DISCUSSION...As of 14z, mosaic radar imagery indicated a leading bow echo over west-central IL with trailing, outflow-dominant convection bisecting I-70 across central MO. The 12z Springfield, MO sounding indicated a very moist low-level air mass with a pronounced capping inversion at the base of an elevated-mixed layer characterized by 700-500-mb lapse rates of 8.5 C/km. Latest short-term model guidance suggests that the ongoing, trailing convection across central MO will linger beyond the scheduled 15z expiration of WWs 156 and 157. However, currently it appears that the cold pool circulation is not sufficiently strong to overcome the currently capping in place. Furthermore, the largely parallel orientation of the line to the mid/upper-level flow will limit the damaging wind potential. Nonetheless, the presence of strong low-level and deep-layer shear will maintain at least an isolated damaging wind and/or hail threat this morning. ..Mead.. 04/27/2026 ...Please see www.spc.noaa.gov for graphic product...

MD 0565 CONCERNING SEVERE THUNDERSTORM WATCH 156...157... FOR EASTERN/NORTHERN MISSOURI AND SOUTHERN ILLINOIS
Mesoscale Discussion 0565 NWS Storm Prediction Center Norman OK 0736 AM CDT Mon Apr 27 2026 Areas affected...Eastern/northern Missouri and southern Illinois Concerning...Severe Thunderstorm Watch 156...157... Valid 271236Z - 271400Z The severe weather threat for Severe Thunderstorm Watch 156, 157 continues. SUMMARY...Elevated storms will persist through mid morning into west central and southern Illinois with the threat for large hail. A separate MCS will spread eastward from WW #156 into WW #157. DISCUSSION...Elevated storms continue in a zone of low-level warm advection on the nose of a 50 kt low-level jet. This area has been near the east edge of the destabilization aloft overnight, and this trend should continue with storms into western and southern IL, where large hail of 1-1.75 inches in diameter will be the main threat. Farther west, earlier supercells in KS/MO have evolved into multiple line segments with occasional mesovortices. The strongest portions of the line have been more north-south oriented, orthogonal to the deep-layer shear vectors and with substantial streamwise vorticity in the low levels. Embedded circulations will continue to be possible, though the storms may slightly out pace northward expansion of the surface warm sector and associated surface-based buoyancy. An isolated mesovortex tornado could occur, but the primary threats will remain damaging winds and large hail in the near term. ..Thompson.. 04/27/2026 ...Please see www.spc.noaa.gov for graphic product...

SPC 1300Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0745 AM CDT Mon Apr 27 2026 Valid 271300Z - 281200Z ...THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF MISSOURI INTO ILLINOIS... ...SUMMARY... Numerous severe thunderstorms are expected from the mid Mississippi/lower Ohio Valleys into the Mid-South through this evening, with a threat for multiple strong to intense tornadoes (EF-3+), widespread severe/damaging wind gusts, and scattered large to very large hail. ...Mid Mississippi Valley/Midwest into the Mid-South/Lower Mississippi Valley... An active severe weather day is forecast for much of the mid MS Valley/lower OH Valleys into the Mid-South. Ongoing thunderstorms this morning complicate the overall scenario to some extent, but a very favorable corridor for intense supercells and strong tornadoes is apparent this afternoon/evening across parts of MO into IL, where a Moderate Risk (Level 4 of 5) has been introduced. Elevated supercells with mainly a hail threat should persist for at least a couple more hours this morning across the mid MS Valley as strong low-level warm advection aids in continued influx of sufficient MUCAPE amid strong deep-layer shear. Multiple clusters/embedded supercells are also ongoing this morning across western into northern MO. This activity should pose a greater threat for scattered severe/damaging winds, along with some hail risk. The tornado threat in the short term (this morning) remains unclear, but it should eventually increase as the boundary-layer across central MO continues to gradually destabilize/moisten. See Mesoscale Discussion 565 for more details on the near-term severe risk with these ongoing thunderstorms. Current expectations are for the greatest severe risk to focus south of these morning thunderstorms. A mid/upper-level trough will eject northeastward from the northern/central Plains into the Midwest and mid MS Valley through the period. Low-level mass response will encourage the primary surface low to consolidate across MN/WI by this evening, with an effective warm front delineated by the morning convection. Aided by daytime heating and steep mid-level lapse rates, a moderately to strongly unstable airmass is expected to be in place by early to mid afternoon across much of central MO/southern IL southward into the Mid-South and lower MS Valley. Strengthening west-southwesterly flow aloft associated with a 50-70 kt mid-level jet will overspread much of the warm sector by peak heating, and a 35-45 kt south-southwesterly low-level jet will both provide ample low-level and deep-layer shear to support supercells. Initially discrete surface-based development appears likely to occur by 19-21Z across the mid MS Valley/Mid-South ahead of the surface cold front, and perhaps along weak low-level confluence zones in the open warm sector. These supercells will exist in a very favorable environment for tornadoes through the afternoon and evening, and multiple strong to intense tornadoes (EF-2/3+) appear likely, especially from parts of MO into IL along/near the effective front. This strong tornado threat may also extend farther south into AR/TN, but confidence is somewhat lower with southward extent due to weaker large-scale forcing. Large to very large hail (2-3 inches in diameter) may also occur with any sustained supercells. By early evening, convection will probably tend to consolidate into clusters capable of producing numerous to widespread damaging winds from the mid MS Valley eastward into the lower OH Valley, before eventually weakening tonight as instability gradually decreases. A threat for QLCS and embedded supercell tornadoes will persist through much of the evening and early overnight hours as well given strong low-level shear forecast. To the north of the ongoing morning convection across IA/northern IL/WI, a lesser (but non-zero) severe risk is forecast. This region will have less instability this afternoon, but strong shear. Have maintained the Marginal/Slight Risks for the possibility of isolated to locally scattered hail/damaging winds, and perhaps a couple of tornadoes. ...ArkLaTex into Texas... Confidence in sustained convection occurring from the ArkLaTex southward into TX is lower compared to locations farther north. But, strong heating ahead of a surface dryline could support isolated to scattered supercells capable of producing large to very large hail and occasional damaging winds. Increasing low-level warm/moist advection tonight could foster additional robust thunderstorms along the retreating dryline and eventually the southward-moving cold front. Severe probabilities have been expanded across these regions to account for this potential. ..Gleason/Thornton.. 04/27/2026 Read more

MD 0564 CONCERNING SEVERE THUNDERSTORM WATCH 156... FOR NORTHWEST MISSOURI
Mesoscale Discussion 0564 NWS Storm Prediction Center Norman OK 0559 AM CDT Mon Apr 27 2026 Areas affected...Northwest Missouri Concerning...Severe Thunderstorm Watch 156... Valid 271059Z - 271230Z The severe weather threat for Severe Thunderstorm Watch 156 continues. SUMMARY...A more north-south segment of the line will pose a continued wind/hail threat, as well as isolated tornado threat, into areas immediately south and southeast of Kansas City. DISCUSSION...A second line segment immediately south of Kansas City is intersecting the trailing outflow from the first segment (now in north central MO). As 65-70 F surface temperatures, dewpoints in the mid-upper 60s and at least weak surface-based CAPE along the warm front approaches these storms from the south, the potential for storms rooted at the ground will likewise increase. The KEAX VWP shows very strong low-level shear and streamwise vorticity inflow into this portion of the line, this will be the preferred corridor for mesovortex formation and a local increase in tornado potential the next couple of hours. Otherwise, the potential for 65-75 mph gusts and 1-1.75 inch hail will continue. If the tornado threat continues to increase later this morning, a new tornado watch may become necessary near I-70. ..Thompson.. 04/27/2026 ...Please see www.spc.noaa.gov for graphic product...
