MD 0178 CONCERNING SEVERE THUNDERSTORM WATCH 31...34...35... FOR SOUTHERN MINNESOTA...SOUTHWESTERN WISCONSIN...NORTHERN AND EASTERN IOWA...AND NORTHWESTERN ILLINOIS
Mesoscale Discussion 0178 NWS Storm Prediction Center Norman OK 0806 PM CDT Fri Mar 14 2025 Areas affected...southern Minnesota...southwestern Wisconsin...northern and eastern Iowa...and northwestern Illinois Concerning...Severe Thunderstorm Watch 31...34...35... Valid 150106Z - 150300Z The severe weather threat for Severe Thunderstorm Watch 31, 34, 35 continues. SUMMARY...Severe storms posing primarily a damaging wind risk will continue spreading northeastward across the mid/upper Mississippi Valley area. DISCUSSION...Latest radar loop shows an arcing/broken band of storms from south-central Minnesota southeastward to eastern Iowa, and spreading gradually toward/into northwestern Missouri. Storms are not particularly robust from a reflectivity perspective -- as they remain largely high-based above the remnant deep/dry diurnal boundary layer. Still, given very strong flow aloft, and the dry air remaining sub-cloud, damaging winds will locally remain possible over the next several hours. ..Goss.. 03/15/2025 ...Please see www.spc.noaa.gov for graphic product...

MD 0177 CONCERNING TORNADO WATCH 32... FOR NORTHERN ARKANSAS INTO SOUTHERN AND EASTERN MISSOURI AND INTO SOUTHWESTERN AND CENTRAL ILLINOIS
Mesoscale Discussion 0177 NWS Storm Prediction Center Norman OK 0745 PM CDT Fri Mar 14 2025 Areas affected...northern Arkansas into southern and eastern Missouri and into southwestern and central Illinois Concerning...Tornado Watch 32... Valid 150045Z - 150245Z The severe weather threat for Tornado Watch 32 continues. SUMMARY...Hazardous weather potential -- including strong/damaging winds, large hail, and a few, possibly strong tornadoes -- continues. DISCUSSION...Latest radar loop shows a gradual change in storm character over the past hour or so across south-central Missouri in particular, where substantially more robust supercells have evolved. Development has also increased southward into northern Arkansas. The change in storm character coincides with -- and is likely resulting from -- low-level moistening which is ongoing/spreading northward with time. Storms increased substantially as dewpoints rose into the low 50s, and now mid 50s dewpoints have overspread much of southeastern Missouri and upper 50s to low 60s across northern Arkansas and into the MO Bootheel. Given the highly favorable flow field (veering and strongly increasing with height), this increase in low-level moisture will likely support corresponding increases in severe/tornado potential, including risk for strong tornadoes potential evolving with time. With storms now crossing the Mississippi River in west-central Illinois, and in the next couple of hours farther south including the St. Louis Metro area, a new Tornado Watch will likely be needed across central Illinois and possibly into western Indiana. ..Goss.. 03/15/2025 ...Please see www.spc.noaa.gov for graphic product...

MD 0176 CONCERNING SEVERE POTENTIAL...WATCH POSSIBLE FOR EASTERN TEXAS INTO THE TEXARKANA REGION
Mesoscale Discussion 0176 NWS Storm Prediction Center Norman OK 0739 PM CDT Fri Mar 14 2025 Areas affected...Eastern Texas into the Texarkana region Concerning...Severe potential...Watch possible Valid 150039Z - 150245Z Probability of Watch Issuance...60 percent SUMMARY...Thunderstorms developing along the dryline across eastern TX may pose a severe risk through the next several hours. Storm coverage and intensity are uncertain based on recent convective trends, but conditions will be monitored for possible watch issuance. DISCUSSION...Attempts at convective initiation have been underway for the past hour or so along a dryline across eastern TX into the Texarkana region. A few thunderstorms have managed to develop across east central TX and are showing signs of slow intensification per IR and lightning trends. IR imagery along the remainder of the dryline shows little in the way of imminent convective development; however, latest guidance continues to hint that additional development is possible as the dryline gradually drifts east into an moistening air mass as the primary surface low across KS lifts to the northeast. The convective environment downstream across eastern TX into southwest AR/northwest LA (characterized by MLCAPE upwards of 1500-2000 J/kg and 45-55 knots of effective shear) suggests that robust supercells are possible if cells can sufficiently intensify to become self-sufficient and mature within the favorable air mass. Large hail will likely be the primary threat given very favorable deep-layer shear and mid-level lapse rates, though a tornado threat may emerge given 50-150 m2/s2 0-1 km SRH. Convective trends will continue to be monitored for the need for watch issuance if a sufficiently widespread severe threat materializes. ..Moore/Mosier.. 03/15/2025 ...Please see www.spc.noaa.gov for graphic product...

MD 0175 CONCERNING SEVERE POTENTIAL...WATCH LIKELY FOR EASTERN ARKANSAS INTO NORTHWEST MISSISSIPPI...WESTERN TENNESSEE...AND THE MISSOURI BOOTHEEL
Mesoscale Discussion 0175 NWS Storm Prediction Center Norman OK 0650 PM CDT Fri Mar 14 2025 Areas affected...Eastern Arkansas into northwest Mississippi...western Tennessee...and the Missouri Bootheel Concerning...Severe potential...Watch likely Valid 142350Z - 150145Z Probability of Watch Issuance...80 percent SUMMARY...Thunderstorm development appears possible in the next 1-2 hours across eastern Arkansas. Storms are expected to intensify as they migrate east/northeast into adjacent portions of Mississippi, Missouri, and Tennessee. Watch issuance is likely as the severe threat becomes apparent (though timing is slightly uncertain). DISCUSSION...Recent GOES visible and low-level water-vapor imagery show a band of gradually deepening cumulus across eastern AR on the eastern fringe of a low-level theta-e axis where isentropic ascent is regionally greatest. A few orphan anvils and occasional lightning flashes have been noted within the last 10-30 minutes, suggesting that this may be the early stages of convective initiation that has been consistently depicted in recent HRRR solutions over the past few hours. However, thunderstorms further south across eastern LA that developed in a similar, if not a better from a thermodynamic perspective, convective environment have struggled to maintain intensity and organization over the past hour. Consequently, it remains somewhat uncertain whether robust convective initiation is imminent and how widespread storm coverage will be in the next few hours. Closer proximity to the primary upper trough may support stronger forcing for ascent and perhaps higher probability for successful convective initiation. If storms can develop and intensify, they will likely pose a threat for all convective hazards, including the potential for a strong tornado, given favorable buoyancy, deep-layer shear, and low-level SRH observed from KLZK and KNQA VWPs (the environment is also characterized by SCP values between 12-16 and STP values of 2-4, suggesting a robust convective environment). Convective trends will continue to be monitored, and watch issuance is likely if/when a severe threat begins to materialize. ..Moore/Mosier.. 03/14/2025 ...Please see www.spc.noaa.gov for graphic product...

Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0801 PM CDT Fri Mar 14 2025 Valid 150100Z - 151200Z ...THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS FROM THE MID-MISSISSIPPI VALLEY INTO THE LOWER MISSISSIPPI VALLEY... ...SUMMARY... A regional outbreak of severe thunderstorms will continue tonight across parts of the Lower/Mid Mississippi Valley and portions of the Lower Ohio Valley and Mid-South. Numerous tornadoes, several of which could be strong to intense, widespread severe gusts ranging from 60 to 100 mph, and scattered large hail up to baseball size all appear likely. ...01z Update... Intense mid-level jet is translating across northeast OK/southwest MO early this evening. This feature will advance toward southern Lake MI later tonight as the upper low lifts into northern IA. Impressive 12hr height falls, and shear are noted ahead of this cyclone. With 0-3 ESRH in excess of 400 m2/s2, thermodynamics may be the primary modulator in convective mode this evening/over night. Over the last few hours, richer boundary-layer moisture is beginning to surge into the southeastern influence of this ejecting trough. Lower 60s surface dew points have advanced to near the MO/AR border, and this is boosting instability within the aforementioned environment that strongly favors supercells. Several supercells are in the process of maturing along a corridor from central MO into northwest AR. Latest thinking is this activity will continue to evolve and grow upscale. Multiple long-lived supercells are expected within an environment very favorable for strong-intense tornadoes, especially from eastern MO, south into MS. Farther north, damaging winds remain likely with strongly-forced convection as it surges northeast across the mid-MS Valley into southeast MN/southern WI. Overall, convective complex will steadily shift downstream overnight as LLJ strengthens across eastern IL/IN into southwest lower MI. ..Darrow.. 03/15/2025 Read more
