MD 0184 CONCERNING TORNADO WATCH 32...36... FOR NORTHEAST ARKANSAS INTO THE MISSOURI BOOTHEEL
Mesoscale Discussion 0184 NWS Storm Prediction Center Norman OK 1020 PM CDT Fri Mar 14 2025 Areas affected...Northeast Arkansas into the Missouri Bootheel Concerning...Tornado Watch 32...36... Valid 150320Z - 150515Z The severe weather threat for Tornado Watch 32, 36 continues. SUMMARY...Supercells with a history of producing tornadoes will continue to pose a tornado threat (including significant tornadoes) for the next couple of hours as they move into northeast Arkansas and southeast Missouri. DISCUSSION...Two long-lived supercells moving across north-central AR and south-central MO have had a history of producing tornadoes per dual-pol data and spotter reports. Based on rotational velocity estimates and the magnitude of the convective environment (characterized by STP values up to 10), one or more of these tornadoes were likely significant (EF-2+). These cells will continue to reside in this exceptionally rare STP environment for the next 1-2 hours as they move into far northeast AR and southeast MO. Consequently, the potential for additional long-track and significant (possibly intense) tornadoes will continue across this region. ..Moore.. 03/15/2025 ...Please see www.spc.noaa.gov for graphic product...

MD 0185 CONCERNING TORNADO WATCH 32...37... FOR CENTRAL AND WESTERN ILLINOIS...SOUTHEASTERN MISSOURI...AND NORTHEASTERN AND CENTRAL ARKANSAS
Mesoscale Discussion 0185 NWS Storm Prediction Center Norman OK 1042 PM CDT Fri Mar 14 2025 Areas affected...central and western Illinois...southeastern Missouri...and northeastern and central Arkansas Concerning...Tornado Watch 32...37... Valid 150342Z - 150445Z The severe weather threat for Tornado Watch 32, 37 continues. SUMMARY...Severe/isolated tornado risk to continue from central Illinois southwestward into central Arkansas. DISCUSSION...Latest radar loop shows that supercell storms that moved through the St. Louis area have evolved toward more of a damaging wind risk, as they have interacted with a drier low-level airmass east of the Mississippi River. With that said, damaging wind gusts remain likely, along with ongoing -- albeit somewhat lesser -- tornado potential. Farther south-southwestward along the convective band, more isolated/classic-looking supercells extend across southeastern Missouri, and particularly into northeastern and into central Arkansas. Specifically, strong rotation is noted within several storms in a zone from southeastern Reynolds/northwestern Wayne Counties in Missouri, southwestward to White County Arkansas. Along with risk for damaging winds and hail, greatest tornado risk appears to exist across this zone over the next couple of hours. Southern portions of WW 32 may be extended in time, beyond its scheduled 15/04Z expiration. ..Goss.. 03/15/2025 ...Please see www.spc.noaa.gov for graphic product...

MD 0183 CONCERNING SEVERE POTENTIAL...WATCH LIKELY FOR SOUTH-CENTRAL ARKANSAS
Mesoscale Discussion 0183 NWS Storm Prediction Center Norman OK 0930 PM CDT Fri Mar 14 2025 Areas affected...South-central Arkansas Concerning...Severe potential...Watch likely Valid 150230Z - 150430Z Probability of Watch Issuance...80 percent SUMMARY...Supercell development across south-central Arkansas appears probable in the coming hours as a dryline shifts east. Watch issuance will likely be needed in this region to address this threat. DISCUSSION...KLZK and GOES IR imagery show thunderstorm development southward along a dryline from the Hot Spring, AR region southward towards Texarkana. 02 UTC upper air analyses suggest that low to mid-level winds are not quite as strong compared to northern AR; however, a strengthening low-level jet sampled by KLZK and KSHV VWPs is supporting 0-1 km SRH on the order of 200-300 m2/s2. Improving low-level kinematics combined with slightly better surface moisture/MLCAPE is yielding STP values on the order of 2-4, which implies a robust tornado environment is in place downstream of the developing convection. Discrete to semi-discrete supercells migrating into this air mass may be capable of very large hail (1.5 to 2.0 inches in diameter) and potentially significant (EF-2+) tornadoes. Watch issuance will likely be needed in the near term to address this potential. ..Moore/Mosier.. 03/15/2025 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...JAN...LZK...SHV...

MD 0182 CONCERNING SEVERE THUNDERSTORM WATCH 34...35... FOR SOUTHEASTERN MINNESOTA...FAR EASTERN IOWA...NORTHERN ILLINOIS...AND SOUTHERN WISCONSIN
Mesoscale Discussion 0182 NWS Storm Prediction Center Norman OK 0921 PM CDT Fri Mar 14 2025 Areas affected...southeastern Minnesota...far eastern Iowa...northern Illinois...and southern Wisconsin Concerning...Severe Thunderstorm Watch 34...35... Valid 150221Z - 150345Z The severe weather threat for Severe Thunderstorm Watch 34, 35 continues. SUMMARY...Local risk for damaging wind gusts continues, and may spread into parts of southern Wisconsin east of WW 34. This may require new WW issuance. DISCUSSION...Latest radar loop shows a band of generally weak convection from a reflectivity perspective, moving northeastward across parts of southern Minnesota and eastern Iowa, and into northwestern Illinois. Despite the weak reflectivity structure, the still-dry sub-cloud layer in tandem with very strong flow aloft ahead of the advancing upper low suggests conditions supportive of locally strong wind gusts. Thus -- expect local potential for damaging winds to continue over the next couple of hours across portions of WW 34 and 35, and eventually portions of southern Wisconsin outside of these watches. A new WW issuance may be needed soon, to highlight this potential into southeastern Wisconsin. ..Goss.. 03/15/2025 ...Please see www.spc.noaa.gov for graphic product...

MD 0180 CONCERNING TORNADO WATCH 32... FOR CENTRAL ARKANSAS INTO FAR SOUTH-CENTRAL MISSOURI
Mesoscale Discussion 0180 NWS Storm Prediction Center Norman OK 0843 PM CDT Fri Mar 14 2025 Areas affected...Central Arkansas into far south-central Missouri Concerning...Tornado Watch 32... Valid 150143Z - 150345Z The severe weather threat for Tornado Watch 32 continues. SUMMARY...Multiple supercells across central/north-central AR will pose an increasing tornado threat as they migrate eastward through the next couple of hours, including the potential for a significant tornado. DISCUSSION...Supercells moving out of northwest AR are becoming increasingly organized with several well-defined mid-level mesocyclones evident in KLZK and KSGF velocity imagery. These storms are moving into an environment characterized by STP values on the order of 3-5, which is largely being driven by a corridor of warm air advection between 925-850 mb over north-central AR. This diffuse warm frontal zone is supporting veering winds through the lowest 2 km with a 0-1 km SRH value of 300 m2/s2 sampled by the 00z LZK sounding and around 450 m2/s2 recently sampled by the KLZK VWP. This environment is typically supportive of robust, long-lived supercells with an attendant threat for tornadoes, including significant (EF-2+) tornadoes. The aforementioned convective trends suggest that cells are beginning to realize this environment and that the downstream tornado threat is likely increasing across central to north-central AR. ..Moore.. 03/15/2025 ...Please see www.spc.noaa.gov for graphic product...

MD 0181 CONCERNING TORNADO WATCH 32... FOR EAST-CENTRAL MISSOURI AND INTO ADJACENT WESTERN ILLINOIS
Mesoscale Discussion 0181 NWS Storm Prediction Center Norman OK 0847 PM CDT Fri Mar 14 2025 Areas affected...east-central Missouri and into adjacent western Illinois Concerning...Tornado Watch 32... Valid 150147Z - 150315Z The severe weather threat for Tornado Watch 32 continues. SUMMARY...Tornado threat is forecast to spread into the greater St. Louis area over the next hour. DISCUSSION...Latest surface analysis shows dewpoints now into the mid 50s west of the Mississippi River, southwest of the St. Louis Metro area. This has supported a northward expansion of the axis of greatest mixed-layer CAPE, per recent RAP-based mesoanalysis, with near 1000 J/kg now as far north as St. Louis, and 2000 J/kg to near FAM (Farmington, MO). In response, several supercell storms have organized within the main convective band, and are moving northeastward at 45 kt. At this time, one storm in particular, moving across Franklin County, is showing very strong low-level rotation, with hints of a corresponding minimum in correlation coefficient that would suggest an ongoing tornado. As such, given the background thermodynamic and kinematic environment, potential for a significant tornado appears to exist. This storm will continue to track northeastward toward the St. Louis area, potentially resulting in a particularly dangerous situation. ..Goss.. 03/15/2025 ...Please see www.spc.noaa.gov for graphic product...

MD 0179 CONCERNING TORNADO WATCH 32...33...36... FOR THE ARK-LA-MISS REGION
Mesoscale Discussion 0179 NWS Storm Prediction Center Norman OK 0815 PM CDT Fri Mar 14 2025 Areas affected...The Ark-La-Miss region Concerning...Tornado Watch 32...33...36... Valid 150115Z - 150315Z The severe weather threat for Tornado Watch 32, 33, 36 continues. SUMMARY...The severe threat appears to be increasing across the Ark-La-Miss region as thunderstorms continue to intensify. Further south, the near-term severe threat appears low across eastern Louisiana into southwest Mississippi, though convective development remains possible. DISCUSSION...Thunderstorms continue to develop across southeast AR into western MS with latest GOES imagery showing cloud top heights exceeding regional equilibrium levels (37-38 kft). This suggests that storms are beginning to fully realize the thermodynamic environment and should steadily become more organized given the very favorable kinematic profiles depicted by regional VWPs. Consequently, the severe threat may be increasing for parts of southeast AR and western MS. Further south across eastern LA into southwest MS, initial storms that developed during the 22-00 UTC period have since collapsed despite a favorable convective environment. This was possibly due to inadequate forcing for ascent that did not allow storms to sufficiently intensify and become self-sufficient. Since then, additional attempts at convective initiation have been noted, but have been unsuccessful. For the short term, the severe threat remains low, but continued (though weak) isentropic ascent within a very weakly capped and strongly sheared environment (per the 00 UTC LIX sounding) and bubbling cumulus across the region suggest that severe convection remains possible within the next 2-5 hours (though confidence in this potential is limited). ..Moore.. 03/15/2025 ...Please see www.spc.noaa.gov for graphic product...
