WW 64 SEVERE TSTM KS 011840Z - 020200Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 64 NWS Storm Prediction Center Norman OK 140 PM CDT Mon Apr 1 2024 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Eastern Kansas * Effective this Monday afternoon and evening from 140 PM until 900 PM CDT. * Primary threats include... Scattered large hail and isolated very large hail events to 2.5 inches in diameter likely Scattered damaging wind gusts to 70 mph possible A tornado or two possible SUMMARY...Scattered severe thunderstorm development is expected this afternoon across southeast and eastern Kansas, with the potential for supercells with isolated very large hail (up to 2.5 inches in diameter) and damaging gusts of 60-70 mph. The tornado threat will remain somewhat limited, though an isolated tornado cannot be ruled out, especially later this evening. The severe thunderstorm watch area is approximately along and 50 statute miles east and west of a line from 50 miles south southwest of Chanute KS to 20 miles northwest of Topeka KS. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU4). PRECAUTIONARY/PREPAREDNESS ACTIONS...

MD 0328 CONCERNING TORNADO WATCH 65... FOR MUCH OF CENTRAL OK INTO NORTHERN TX
Mesoscale Discussion 0328 NWS Storm Prediction Center Norman OK 0553 PM CDT Mon Apr 01 2024 Areas affected...much of central OK into northern TX Concerning...Tornado Watch 65... Valid 012253Z - 020030Z The severe weather threat for Tornado Watch 65 continues. SUMMARY...The severe threat continues across Tornado Watch 65. Very large (2-3 inch diameter) hail appears to be the main threat, though a few tornadoes remain possible with the more dominant supercells. DISCUSSION...Deep-layer ascent from the ejecting mid-level trough is overspreading the southern Plains, likely contributing to the recent uptick in convective coverage and intensity over southwestern into central OK. Despite persistent cloud cover and the presence of a broader rain shield overspreading western into central OK, adequate deep-layer shear and overall buoyancy will still support an appreciable severe threat into the evening. The 19Z OUN observed sounding showed 9 C/km mid-level lapse rates atop a capping inversion, which has been gradually eroding with time. Regional VADs, the 19Z observed sounding, and 22Z mesoanalysis, all depict elongated hodographs, with over 70 kts of effective bulk shear present. The very steep mid-level lapse rates and strong effective bulk shear all suggest that large hail (some stones falling within the 2-3 inch diameter range) will be possible with any more persistent, mature supercells that can develop. Despite current meager low-level shear, an increase in low-level jet intensity may boost SRH later this evening, potentially accompanied by an increasing tornado threat, especially in eastern OK. ..Squitieri.. 04/01/2024 ...Please see www.spc.noaa.gov for graphic product...

MD 0326 CONCERNING SEVERE THUNDERSTORM WATCH 66... FOR PORTIONS OF WESTERN TEXAS
Mesoscale Discussion 0326 NWS Storm Prediction Center Norman OK 0526 PM CDT Mon Apr 01 2024 Areas affected...portions of western Texas Concerning...Severe Thunderstorm Watch 66... Valid 012226Z - 020000Z The severe weather threat for Severe Thunderstorm Watch 66 continues. SUMMARY...The severe threat continues across Severe Thunderstorm Watch 66. Very large hail and hurricane-force gusts will remain possible with the strongest storms through evening, and a tornado cannot be ruled out. Storms may develop farther south across southwestern into central TX and local WW extensions or new watches may eventually become necessary. DISCUSSION...Semi-discrete storms, including supercells, have been progressing eastward across portions of northwestern TX with a history of up to baseball sized hail and near 90 mph measured gusts. Diurnal heating ahead of the ongoing line of storms has allowed for surface temperatures to warm to over 80 F amid upper 60s F dewpoints, minimizing CINH and boosting MLCAPE to 2000 J/kg (per 22Z mesoanalysis). Buoyancy is modest, but more than adequate in supporting continued significant-severe weather given the presence of 80+ kts of effective bulk shear (driven by a 30+ kt low-level jet overspread by over 80 kts of 500 mb southwesterly flow). As such, the more sustained supercell structures may continue to produce severe hail in the 2-3 inch diameter range, along with severe gusts peaking between 75-90 mph. The best chance for significant-severe storms will be over northwestern into north-central TX, where deep-layer ascent is the strongest. Additionally, regional VADs and 22Z mesoanalysis does show some slight low-level hodograph curvature, suggesting that a tornado cannot be ruled out as well. Farther south, storms are attempting to develop closer to the Rio Grande. However, overall forcing for ascent is weaker, raising questions pertaining to storm coverage. Still, given the strong deep-layer shear present, any storms that can mature and become sustained will present a severe hail/wind risk. A local spatial extension of Severe Thunderstorm Watch 66 may be needed if confidence in convective coverage increases farther south into southern and central TX. ..Squitieri.. 04/01/2024 ...Please see www.spc.noaa.gov for graphic product...

MD 0327 CONCERNING TORNADO WATCH 64...67... FOR EASTERN KANSAS AND WESTERN/CENTRAL MISSOURI
Mesoscale Discussion 0327 NWS Storm Prediction Center Norman OK 0528 PM CDT Mon Apr 01 2024 Areas affected...eastern Kansas and western/central Missouri Concerning...Tornado Watch 64...67... Valid 012228Z - 020000Z The severe weather threat for Tornado Watch 64, 67 continues. SUMMARY...Numerous supercells are expected this evening with large to very large hail likely. The tornado threat will increase near and after sunset. DISCUSSION...A mature supercell has developed in southeast Kansas with hail up to golf ball sized reported. Additional supercells have started to develop along the warm front in central Missouri. MLCAPE of 1200 to 1500 J/kg and effective shear in excess of 70 knots (per SGF VWP) will support large to very large hail with any storms. SPC mesoanalysis shows STP around 1 to 1.5 at 22Z and the WoFs suggest STP around 3 by 00Z as the low-level jet strengthens. Therefore, expect a gradual increase in tornado intensity through the evening. ..Bentley.. 04/01/2024 ...Please see www.spc.noaa.gov for graphic product...

MD 0329 CONCERNING TORNADO WATCH 68... FOR EASTERN MISSOURI ACROSS ILLINOIS AND INTO FAR SOUTHWEST INDIANA.
Mesoscale Discussion 0329 NWS Storm Prediction Center Norman OK 0645 PM CDT Mon Apr 01 2024 Areas affected...eastern Missouri across Illinois and into far southwest Indiana. Concerning...Tornado Watch 68... Valid 012345Z - 020115Z The severe weather threat for Tornado Watch 68 continues. SUMMARY...Training supercells will continue along a warm front from eastern Missouri to far western Indiana this evening. DISCUSSION...A mature supercell is moving through the northern St. Louis suburbs with another supercell east of Jefferson City. Thus far, the maximum hail size with these storms has been golf ball sized, but even larger hail is possible, especially as the low-level jet strengthens this evening. A vorticity rich environment along this warm front will support a tornado threat through the evening with the WoFs suggesting a narrow corridor of 2 STP along the front. WoFs 0-2km UH probabilities suggest the lead supercell will continue to support a tornado threat for the next several hours with peak probabilities in south-central Illinois. ..Bentley.. 04/01/2024 ...Please see www.spc.noaa.gov for graphic product...
