MD 0547 CONCERNING SEVERE POTENTIAL...WATCH LIKELY FOR SOUTHEASTERN IOWA...NORTHWESTERN ILLINOIS...AND FAR NORTHERN MISSOURI
Mesoscale Discussion 0547 NWS Storm Prediction Center Norman OK 0517 PM CDT Sat Apr 27 2024 Areas affected...Southeastern Iowa...Northwestern Illinois...and far Northern Missouri Concerning...Severe potential...Watch likely Valid 272217Z - 272315Z Probability of Watch Issuance...80 percent SUMMARY...Severe risk increasing. Watch likely to be issued within the next hour. DISCUSSION...Storm coverage has increased along the frontal boundary extending through central Iowa to areas just north of the Wisconsin/Illinois border. Air mass destabilization ahead of WW147 has yielded MLCAPE around 2000-3000 J/kg and modest deep layer shear. VAD profiles from DMX depict a cyclonic curved hodograph with SFC to 1km shear profiles with 200 m2/s2. Surface vorticity is likely maximized further along the boundary, where thunderstorms have been developing. ..Thornton/Smith.. 04/27/2024 ...Please see www.spc.noaa.gov for graphic product...

MD 0546 CONCERNING SEVERE POTENTIAL...TORNADO WATCH LIKELY FOR EASTERN KS/WESTERN MO
Mesoscale Discussion 0546 NWS Storm Prediction Center Norman OK 0431 PM CDT Sat Apr 27 2024 Areas affected...Eastern KS/Western MO Concerning...Severe potential...Tornado Watch likely Valid 272131Z - 272230Z Probability of Watch Issuance...95 percent SUMMARY...Tornado watch is warranted for eastern Kansas and western Missouri. DISCUSSION...Northeast-southwest oriented corridor of severe convection extends across southeast KS into north-central OK. Supercells are embedded along this zone which is gradually lifting northeast into a modestly buoyant and strongly sheared environment. LLJ is forecast to increase across eastern OK into southwest MO later this evening which will encourage this complex to spread/develop downstream. While some clustering is evident, supercells will likely be embedded/maintained given the strong shear. Tornadoes remain a distinct possibility along with large hail. ..Darrow/Smith.. 04/27/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...SGF...EAX...TOP...ICT...

MD 0545 CONCERNING TORNADO WATCH 145...147... FOR EASTERN KANSAS INTO NORTHERN MISSOURI AND SOUTHERN IOWA
Mesoscale Discussion 0545 NWS Storm Prediction Center Norman OK 0340 PM CDT Sat Apr 27 2024 Areas affected...eastern Kansas into northern Missouri and southern Iowa Concerning...Tornado Watch 145...147... Valid 272040Z - 272215Z The severe weather threat for Tornado Watch 145, 147 continues. SUMMARY...The threat for brief tornadoes as well as damaging outflow winds and hail continues within the watch areas, and may spread east, necessitating additional watch areas. DISCUSSION...Supercells formed along a retreating boundary/warm front which now extends from northeast KS and northwest MO, and from southwest IA into southern WI. Low-level shear is maximized near this boundary with 0-1 SRH near 150 m2/s2 and weaker values into the open warm sector. Heating continues along the boundary, and the 18Z DVN sounding shows ample instability and lapse rates to sustain strong to severe storms, with generally unidirectional shear profiles. However, only minimal low-level hodograph augmentation may be necessary for a tornado risk with any supercells that move across northern MO/IA through the afternoon. As such, the threat may eventually extend beyond WW 147, and another watch and/or extension may become necessary depending on trends. Farther south into eastern KS and western MO, outflow from initial activity extends from northeast KS into north-central OK, while an unstable air mass remains just to the east. MLCAPE over 2500 J/kg as well as ample deep-layer shear will support supercells and or damaging bows this evening, with all modes of severe possible. ..Jewell.. 04/27/2024 ...Please see www.spc.noaa.gov for graphic product...

MD 0544 CONCERNING TORNADO WATCH 146... FOR WESTERN NORTH TX AND SOUTHWEST OK
Mesoscale Discussion 0544 NWS Storm Prediction Center Norman OK 0319 PM CDT Sat Apr 27 2024 Areas affected...Western north TX and southwest OK Concerning...Tornado Watch 146... Valid 272019Z - 272145Z The severe weather threat for Tornado Watch 146 continues. SUMMARY...Pair of potentially long-lived supercells within the southern portion of WW 146 may evolve with an intense tornado and very large hail threat. DISCUSSION...A potentially long-lived, slow-moving discrete supercell is centered over Knox County, TX. This supercell appears to be anchored along the far southern portion of the broader convective plume that extends north across OK/KS. With full insolation in the warm-moist sector inflow to its southeast, its plausible that a long-lived supercell will persist for the next 2-3 hours. Amid MLCAPE of 3000 J/kg and mid 60s surface dew points to its southeast, a cyclic tornadic supercell could evolve beyond the very large hail threat with up to baseballs reported thus far. The supercell to its northeast in Wilbarger County, TX will also have potential to further intensify as it spreads towards and northwest of the Wichita Falls vicinity, given 0-1 km SRH of 100-200 m2/s2 per FDR VWP data. ..Grams.. 04/27/2024 ...Please see www.spc.noaa.gov for graphic product...

MD 0542 CONCERNING SEVERE POTENTIAL...WATCH POSSIBLE FOR MUCH OF WESTERN KANSAS INTO SOUTHEAST COLORADO
Mesoscale Discussion 0542 NWS Storm Prediction Center Norman OK 0115 PM CDT Sat Apr 27 2024 Areas affected...much of western Kansas into southeast Colorado Concerning...Severe potential...Watch possible Valid 271815Z - 272045Z Probability of Watch Issuance...40 percent SUMMARY...A few severe storms may develop this afternoon near the front from southeast Colorado into parts of western Kansas, with large hail the primary threat. DISCUSSION...Surface analysis shows low pressure over southwest KS, with a dryline near the OK/TX Panhandle border. A prominent surface front stretches from southeast CO across west-central KS, with a few storms already near the central to northeast KS portion of the front. Substantial storms are ongoing from northwest OK into south-central KS near ICT, and this activity has produced outflow which is affecting destabilization over central KS currently. However, further heating will likely lead to sufficient instability to support a few severe storms capable of hail. Northeast surface winds north of the front will further aid deep-layer shear, and potentially support left-moving storms with hail potential. ..Jewell/Hart.. 04/27/2024 ...Please see www.spc.noaa.gov for graphic product...

Mesoscale Discussion 0543 NWS Storm Prediction Center Norman OK 0154 PM CDT Sat Apr 27 2024 Areas affected...Northeast OK and southeast KS Concerning...Tornado Watch 145...146... Valid 271854Z - 272030Z The severe weather threat for Tornado Watch 145, 146 continues. SUMMARY...As severe storms in north-central Oklahoma and south-central Kansas spread east late this afternoon, an additional tornado watch will likely be needed. DISCUSSION...The airmass ahead of severe storms in south-central KS and north-central OK continues to destabilize as surface temps have warmed in the upper 70s to low 80s across most of eastern OK into far southeast KS. While low-level shear within this part of the warm-moist sector is relatively modest per INX VWP data, it will strengthen based on upstream TLX data. A mix of discrete and semi-discrete supercells occasionally embedded within clusters should spread east-northeast through late afternoon. As this occurs, all severe hazards will be possible, some of which may be significant. ..Grams.. 04/27/2024 ...Please see www.spc.noaa.gov for graphic product...
