Severe Storms

SPC 1200Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0100 AM CDT Tue Apr 02 2024 Valid 021200Z - 031200Z ...THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS ACROSS THE OHIO VALLEY... ...SUMMARY... A potentially substantial severe weather outbreak -- possibly including a few significant/long-track tornadoes -- is anticipated this afternoon and evening, with the highest probability centered over the Ohio Valley. Severe risk exists as far south as the Gulf Coast, and as far east as western portions of Virginia and the Carolinas. ...Discussion... Strong northern-stream upper low, currently located over southern MB, is forecast to drop south across MN into northern IL late in the period. This evolution is driven in part by a 500mb speed max that will translate across the central Plains, increasing to near 100kt over eastern KS/OK by 03/12z. Intense 12hr midlevel height falls are forecast across much of the Great Lakes, OH/TN Valley, and the northern Gulf States, where values in excess of 200m are expected during the latter half of the period. Synoptic front that is currently draped across the OH Valley will be encouraged to gradually advance north due to the digging trough; however, an extensive corridor of convection currently extends across the MS Valley into the OH valley, which is maintaining cool boundary-layer conditions north of I-70. Latest water-vapor imagery suggests a southern-stream short-wave trough is progressing across eastern KS/eastern OK. This feature will progress downstream and likely aid early-day thunderstorm development near the confluence of the MS/OH Rivers. Seasonally high PW airmass currently extends across northern AR/southern MO into southern IL. NAM forecast sounding for JBR at 15z exhibits 60kt surface-6km bulk shear with SBCAPE on the order of 1500 J/kg. Discrete supercells may evolve ahead of this feature then spread/develop northeast across southern IN/KY into OH. Some uncertainty exists across northern OH/IN regarding destabilization. It's not entirely clear if ongoing convection will allow the warm front to lift appreciably north of its current position. However, large-scale pattern is quite dynamic and favors surface low deepening over southern Lake MI during the latter half of the pattern. NAM struggles to reflect this scenario, thus weaker instability is forecast at higher latitudes. Tornadoes, damaging winds, and large hail are expected with supercells that evolve across the warm sector. Some tornadoes may be long-lived and strong. Farther south, a bimodal severe threat may ultimately evolve with a secondary corridor of more concentrated severe across portions of the northern Gulf States. 500mb speed max is forecast to eject across northern Mexico into TX by 03/00z. This feature will intensify as it translates across LA into eastern TN by the end of the period. There is some concern that severe probabilities may need to be increased across this region to account for this low-latitude speed max during the evening/overnight hours. Strong shear will support supercells along with a threat for tornadoes, damaging winds, and hail. ..Darrow/Bentley.. 04/02/2024 Read more

MD 0336 CONCERNING TORNADO WATCH 71... FOR PORTIONS OF CENTRAL MISSOURI INTO SOUTHWESTERN ILLINOIS
Mesoscale Discussion 0336 NWS Storm Prediction Center Norman OK 1126 PM CDT Mon Apr 01 2024 Areas affected...portions of central Missouri into southwestern Illinois Concerning...Tornado Watch 71... Valid 020426Z - 020600Z The severe weather threat for Tornado Watch 71 continues. SUMMARY...The severe threat continues across Tornado Watch 71. Damaging gusts and a few QLCS tornadoes remain a concern over the next few hours, particularly with any circulations that can interact with a boundary draped across central MO. DISCUSSION...A QLCS is progressing across southwestern into central MO and is interacting with a quasi-stationary boundary left behind by earlier storms. Multiple mesovortices have developed along the intersection of the QLCS and the aforementioned boundary, and this behavior is expected to continue over the next few hours. Damaging gusts may also accompany bowing segments associated with the QLCS. Elevated supercells behind the boundary are also in progress to the west the St. Louis metro area, and these storms may pose a continued severe hail/wind risk as well. ..Squitieri.. 04/02/2024 ...Please see www.spc.noaa.gov for graphic product...

WW 71 TORNADO IL MO 020330Z - 020800Z
URGENT - IMMEDIATE BROADCAST REQUESTED Tornado Watch Number 71 NWS Storm Prediction Center Norman OK 1030 PM CDT Mon Apr 1 2024 The NWS Storm Prediction Center has issued a * Tornado Watch for portions of Central Illinois Southwest into East-Central Missouri * Effective this Monday night and Tuesday morning from 1030 PM until 300 AM CDT. * Primary threats include... A few tornadoes and a couple intense tornadoes possible 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 likely SUMMARY...Multiple clusters of strong/severe thunderstorms will track east-northeastward across the watch area through the night, posing a risk of locally damaging wind gusts, large hail, and a few tornadoes. The tornado watch area is approximately along and 40 statute miles north and south of a line from 10 miles north northwest of Monett MO to 20 miles north of Salem IL. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU1). 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 67...WW 68...WW 69...WW 70... AVIATION...Tornadoes and a few severe thunderstorms with hail surface and aloft to 2 inches. Extreme turbulence and surface wind gusts to 65 knots. A few cumulonimbi with maximum tops to 500.

MD 0335 CONCERNING SEVERE THUNDERSTORM WATCH 70... FOR PORTIONS OF SOUTHEASTERN OKLAHOMA INTO NORTHEASTERN TEXAS AND FAR WESTERN ARKANSAS
Mesoscale Discussion 0335 NWS Storm Prediction Center Norman OK 1045 PM CDT Mon Apr 01 2024 Areas affected...portions of southeastern Oklahoma into northeastern Texas and far western Arkansas Concerning...Severe Thunderstorm Watch 70... Valid 020345Z - 020515Z The severe weather threat for Severe Thunderstorm Watch 70 continues. SUMMARY...The severe threat continues across Severe Thunderstorm Watch 70. The main severe threat exists across northern portions of the watch as a line of storms approaches from the west. Damaging gusts are the main threat, though a tornado cannot be ruled out. DISCUSSION...The earlier QLCS with embedded supercells across northern TX has diminished in intensity given increasing inhibition. However, a pronounced QLCS is in progress across central OK, and this convection may move into Severe Thunderstorm Watch 70 over the next few hours with a damaging gust threat. Portions of the watch across eastern OK into western AR will most likely experience this QLCS later this evening. It is unclear how far south the QLCS will build into TX, so the severe threat is more conditional across the TX portion of the watch. Regional VADs, 03Z mesoanalysis, and RAP forecast soundings all show elongated hodographs with decent low-level curvature. However, CINH is increasing above the boundary layer given nocturnal cooling, tempering the tornado threat. Nonetheless, a tornado cannot be completely ruled out if a QLCS circulation can ingest any surface-based parcels. ..Squitieri.. 04/02/2024 ...Please see www.spc.noaa.gov for graphic product...
