Severe Storms

SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0747 PM CDT Sat Mar 15 2025 Valid 160100Z - 161200Z ...THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS FROM EXTREME SOUTHEAST MISSISSIPPI ACROSS MUCH OF ALABAMA INTO WESTERN GEORGIA AND THE WESTERN FLORIDA PANHANDLE... ...SUMMARY... Widespread severe convection, including the risk for strong tornadoes continues this evening. Severe threat will spread across Alabama into Georgia/Florida Panhandle later tonight. ...01z Update... Strong short-wave trough is evident on water-vapor imagery over eastern OK/TX. This feature will shift into the lower MS Valley later this evening as 100+kt 500mb speed max translates through the base of the trough into the central Gulf States. While the primary synoptic front is lagging the organized band of convection, ample low-level convergence/inflow is noted across southern AL/western FL Panhandle into western GA. This will encourage ongoing activity to propagate downstream, aided by the fast-approaching mid-level speed max/short wave. This corridor of storms is multifaceted with embedded supercells and bowing type structures, within an otherwise broad precip shield. Latest observations suggest the most buoyant air mass is correlated with mid-upper 60s surface dew points, which have advanced as far north as ALX in eastern AL. Air mass recovery is expected downstream into western GA which should support a continuation of ongoing severe into this region. 00z sounding from FFC exhibits fairly steep lapse rates through 6km, and further boundary-layer moistening will prove beneficial for further destabilization. Strong tornado threat continues with any supercells as large-scale support and very strong shear remain favorable. Additionally, damaging winds can be expected with any line segments, and bowing structures. Hail is also possible, especially across the more buoyant southern areas. ..Darrow.. 03/16/2025 Read more

WW 46 TORNADO AL MS 151725Z - 160100Z
URGENT - IMMEDIATE BROADCAST REQUESTED Tornado Watch Number 46 NWS Storm Prediction Center Norman OK 1225 PM CDT Sat Mar 15 2025 The NWS Storm Prediction Center has issued a * Tornado Watch for portions of Western, Central, and Northern Alabama Southeast Mississippi * Effective this Saturday afternoon and evening from 1225 PM until 800 PM CDT. ...THIS IS A PARTICULARLY DANGEROUS SITUATION... * Primary threats include... Numerous tornadoes and several intense tornadoes expected Scattered damaging winds and isolated significant gusts to 75 mph likely Scattered large hail and isolated very large hail events to 2.5 inches in diameter likely SUMMARY...Intense supercells capable of producing numerous tornadoes will spread eastward from Mississippi into Alabama this afternoon and evening. Given the very favorable environment, multiple intense to potentially violent tornadoes (EF-3/EF-4+) appear possible. Clusters of thunderstorms and embedded supercells will also pose a threat for severe/damaging winds of 60-75 mph, and large hail around 1.5-2.5 inches in diameter. The tornado watch area is approximately along and 65 statute miles east and west of a line from 20 miles north northeast of Huntsville AL to 55 miles west southwest of Evergreen AL. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU6). PRECAUTIONARY/PREPAREDNESS ACTIONS... REMEMBER...A Tornado Watch means conditions are favorable for tornadoes and 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. && OTHER WATCH INFORMATION...CONTINUE...WW 44...WW 45... AVIATION...Tornadoes and a few severe thunderstorms with hail surface and aloft to 2.5 inches. Extreme turbulence and surface wind gusts to 65 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 23040. ...Gleason Read more

WW 47 TORNADO TN 151750Z - 160200Z
URGENT - IMMEDIATE BROADCAST REQUESTED Tornado Watch Number 47 NWS Storm Prediction Center Norman OK 1250 PM CDT Sat Mar 15 2025 The NWS Storm Prediction Center has issued a * Tornado Watch for portions of Middle Tennessee * Effective this Saturday afternoon and evening from 1250 PM until 900 PM CDT. * Primary threats include... Several tornadoes and a couple intense tornadoes likely Widespread damaging winds and isolated significant gusts to 75 mph likely Scattered large hail and isolated very large hail events to 2 inches in diameter possible SUMMARY...A line of thunderstorms will spread east-northeastward across middle Tennessee this afternoon and evening. Widespread damaging winds up to 60-75 mph are expected along with several tornadoes as the environment becomes increasingly favorable for severe thunderstorms. A couple strong to intense tornadoes also appear posssible with any embedded supercells. The tornado watch area is approximately along and 65 statute miles east and west of a line from 65 miles east northeast of Nashville TN to 85 miles south southwest of Nashville TN. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU7). PRECAUTIONARY/PREPAREDNESS ACTIONS... REMEMBER...A Tornado Watch means conditions are favorable for tornadoes and 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. && OTHER WATCH INFORMATION...CONTINUE...WW 44...WW 45...WW 46...
