WW 118 SEVERE TSTM IL MO 042210Z - 050500Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 118 NWS Storm Prediction Center Norman OK 510 PM CDT Fri Apr 4 2025 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of South Central Illinois Southern Missouri * Effective this Friday afternoon from 510 PM until Midnight CDT. * Primary threats include... Scattered damaging wind gusts to 60 mph likely Scattered large hail events to 1.5 inches in diameter likely A tornado or two possible SUMMARY...Clusters of thunderstorms will overspread the watch area through the evening, posing a risk of large hail and perhaps locally damaging wind gusts. The severe thunderstorm watch area is approximately along and 40 statute miles north and south of a line from 30 miles south of Springfield MO to 50 miles east of Mount Vernon IL. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU8). 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 113...WW 114...WW 115...WW 116...WW 117... AVIATION...A few severe thunderstorms with hail surface and aloft to 1.5 inches. Extreme turbulence and surface wind gusts to 50 knots. A few cumulonimbi with maximum tops to 450. Mean storm motion vector 24035. ...Hart Read more

MD 0401 CONCERNING TORNADO WATCH 113... FOR NORTHEAST TX/NORTHWEST LA INTO NORTH-CENTRAL/NORTHEAST AR
Mesoscale Discussion 0401 NWS Storm Prediction Center Norman OK 0804 PM CDT Fri Apr 04 2025 Areas affected...Northeast TX/Northwest LA into north-central/northeast AR Concerning...Tornado Watch 113... Valid 050104Z - 050230Z The severe weather threat for Tornado Watch 113 continues. SUMMARY...Tornado potential will continue to focus across far northeast Texas, far northwest Louisiana northeastward into south-central to north-central/northeast Arkansas this evening. Tornado Watch 113 continues until 9pm CDT/02z, but a replacement (and east-northeastward expanding) Tornado Watch is expected. DISCUSSION...Scattered intense storms including embedded/semi-discrete supercells will continue to focus this evening especially within a southwest/northeast-oriented corridor across southwest/central into north-central/northeast Arkansas. The complex/muddled convective mode will continue to be a factor, but the moist environment and strengthening low-level shear will continue to support tornado potential, possibly including a strong tornado, aside from damaging winds/some hail. The 00z observed sounding from Little Rock features a moisture-rich boundary layer with a 70F surface dewpoint and 13.8 g/kg mean mixing ratio. 0-1km SRH was around 330 m2/s2, and increase over the past couple hours per prior WSR-88D VWP data, with a further increase expected over the next hour or two especially from southwest/central Arkansas northeastward into northeast Arkansas/far southeast Missouri. ..Guyer.. 04/05/2025 ...Please see www.spc.noaa.gov for graphic product...

SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0759 PM CDT Fri Apr 04 2025 Valid 050100Z - 051200Z ...THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS FROM THE ARKLATEX INTO SOUTHEAST MISSOURI... ...SUMMARY... Clusters of severe storms are expected across portions of Texas across the ArkLaTex and into the lower Ohio Valley tonight. The greatest threat for tornadoes, large hail and damaging winds continues from the ArkLaTex into southeast Missouri, including potential for strong to potentially intense tornadoes. ...01z Update... Primary upper low has settled along the international border west of TUS this evening. A secondary short-wave trough is expected to advance into west TX later tonight when another bout of elevated convection will evolve atop cooler air mass wedged deep into this portion of the southern Plains. Hail will once again be expected with this late-night activity. Downstream, a slow-moving corridor of strong-severe thunderstorms continues from the Arklatex-northern AR-southeast MO-southern IL. Supercells are embedded along the frontal zone and this activity will continue through the overnight hours as a weak short-wave ejects toward the OH Valley. LLJ is forecast to strengthen into southern IL over the next several hours and this could aid upscale growth as warm advection intensifies into this region. With surface dew points rising through the upper 60s to near 70 near the confluence of the MS/OH Rivers, ample buoyancy exists for robust updrafts. 00z soundings from SHV and LZK support this with SBCAPE in excess of 3000 J/kg. Given the very strong deep-layer shear strong tornadoes remain a possibility. ..Darrow.. 04/05/2025 Read more
