Severe Storms

SPC 1200Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1234 AM CDT Sat Mar 15 2025 Valid 151200Z - 161200Z ...THERE IS A HIGH RISK OF SEVERE THUNDERSTORMS ALONG A CORRIDOR FROM CENTRAL MISSISSIPPI INTO NORTHERN/CENTRAL ALABAMA... ...SUMMARY... A tornado outbreak is expected across the central Gulf Coast States and Deep South into the Tennessee Valley. Numerous significant tornadoes, some of which should be long-track and potentially violent, are expected this afternoon and evening. The most dangerous tornado threat should begin across eastern Louisiana and Mississippi during the late morning to afternoon, spread across Alabama late day into the evening, and reach western parts of the Florida Panhandle and Georgia Saturday night. ...Central Gulf States/Tennessee Valley Region... Strong cyclone that is lifting northeast across the upper MS Valley will eject into northwest Ontario later today as a very strong mid-level speed max digs southeast across northern Mexico into south-central TX. Later tonight, this jet will translate into the central Gulf States with winds in excess of 110kt. In response to this feature, a surface low should evolve along the trailing boundary along the TX/LA border early in the period, then track northeast into western KY by 16/00z. Additionally, an intense LLJ will evolve by mid day across northern MS and strengthen during the afternoon as it gradually shifts downstream into AL/middle TN/KY by early evening. Net result should be for a bit higher moisture content to advance farther north than previous thought. Early this morning, an arcing band of scattered supercells extended across southern IL into eastern AR. More isolated activity has persisted much of the late evening across portions of MS. Latest thinking is convective overturning should remain minimal across the lower MS Valley and this will allow significant destabilization to materialize ahead of the surface low early in the period. Latest surface data depicts lower 70s dew points across southern LA/southwest MS, with mid 60s approaching the south side of the Memphis metro. Confidence is increasing that a corridor of strong buoyancy and intense shear will be in place prior to the aforementioned speed max/short-wave trough. Forecast soundings exhibit steep mid-level lapse rates with ESRH in excess of 500 m2/s2 across a broad swath of the central Gulf States, especially the categorical High Risk delineation. While scattered strong/severe thunderstorms will likely be ongoing at the start of the period across the western TN Valley, convection should increase in intensity by late morning across LA as the leading edge of the approaching short wave begins to influence this region. Continued boundary-layer heating will lead to subsequent development and supercells should mature and race northeast as the flow strengthens. This flow regime favors long-lived tornadoes, and the parameter space suggests potentially violent, long-track tornadoes. This activity will grow upscale in both coverage and intensity through late afternoon as the overall severe complex shifts downstream. Large hail and damaging winds may also accompany these storms, but the primary concern today will be the likelihood for a tornado outbreak, especially across Mississippi into Alabama. ..Darrow/Moore.. 03/15/2025 Read more

WW 35 SEVERE TSTM IA IL MO LM 142355Z - 150700Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 35 NWS Storm Prediction Center Norman OK 655 PM CDT Fri Mar 14 2025 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Eastern Iowa Northern Illinois Far Northeast Missouri Lake Michigan * Effective this Friday night and Saturday morning from 655 PM until 200 AM CDT. * Primary threats include... Scattered damaging winds and isolated significant gusts to 80 mph likely Scattered large hail and isolated very large hail events to 2 inches in diameter possible A tornado or two possible SUMMARY...Ongoing line of showers and thunderstorms is expected to progress quickly northeastward/eastward over the next several hours. Very strong low- to mid-level wind fields exist, supporting the potential for strong gust with any deeper, more sustained storms. Some isolated hail is possible as well. Dry low-levels are expected to keep the tornado potential very low, although still none zero given the strongly sheared environment. The severe thunderstorm watch area is approximately along and 50 statute miles north and south of a line from 25 miles southwest of Cedar Rapids IA to 45 miles east northeast of Marseilles IL. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU5). 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...WW 34... AVIATION...A few severe thunderstorms with hail surface and aloft to 2 inches. Extreme turbulence and surface wind gusts to 70 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 24035. ...Mosier Read more
