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...

WW 34 SEVERE TSTM IA MN WI 142240Z - 150600Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 34 NWS Storm Prediction Center Norman OK 540 PM CDT Fri Mar 14 2025 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Northern Iowa South-Central and Southeast Minnesota Far Southwest Wisconsin * Effective this Friday afternoon and Saturday morning from 540 PM until 100 AM CDT. * Primary threats include... Scattered damaging wind gusts to 70 mph likely Scattered large hail and isolated very large hail events to 2 inches in diameter possible SUMMARY...Strong to severe thunderstorms ongoing across Iowa will continue to spread northward/northeastward over the next few hours.

For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU4). PRECAUTIONARY/PREPAREDNESS ACTIONS... REMEMBER...A Severe Thunderstorm Watch means conditions are favorable for severe thunderstorms in and close to the watch area. Persons in these areas should be on the lookout for threatening weather conditions and listen for later statements and possible warnings. Severe thunderstorms can and occasionally do produce tornadoes. && OTHER WATCH INFORMATION...CONTINUE...WW 30...WW 31...WW 32...WW 33...
