WW 363 TORNADO OK 032240Z - 040300Z
URGENT - IMMEDIATE BROADCAST REQUESTED Tornado Watch Number 363 NWS Storm Prediction Center Norman OK 540 PM CDT Tue Jun 3 2025 The NWS Storm Prediction Center has issued a * Tornado Watch for portions of Central and Eastern Oklahoma * Effective this Tuesday afternoon and evening from 540 PM until 1000 PM CDT. * Primary threats include... A few tornadoes possible Scattered damaging wind gusts to 70 mph likely Scattered large hail and isolated very large hail events to 2 inches in diameter possible SUMMARY...A cluster of supercell thunderstorms across central Oklahoma will track northeastward across the watch for the next few hours. Localized wind fields have become favorable for a risk of a few tornadoes, along with damaging winds and large hail. The tornado watch area is approximately along and 40 statute miles east and west of a line from 35 miles southwest of Ardmore OK to 25 miles east of Tulsa OK. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU3). 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 359...WW 360...WW 361...WW 362... AVIATION...Tornadoes and a few severe thunderstorms with hail surface and aloft to 2 inches. Extreme turbulence and surface wind gusts to 60 knots. A few cumulonimbi with maximum tops to 500.

MD 1100 CONCERNING TORNADO WATCH 363... FOR SOUTH-CENTRAL INTO NORTHEAST OKLAHOMA
Mesoscale Discussion 1100 NWS Storm Prediction Center Norman OK 0644 PM CDT Tue Jun 03 2025 Areas affected...South-central into northeast Oklahoma Concerning...Tornado Watch 363... Valid 032344Z - 040115Z The severe weather threat for Tornado Watch 363 continues. SUMMARY...Tornadoes, particularly with discrete storms in south-central Oklahoma, and damaging winds will remain possible into the evening. DISCUSSION...A few discrete storms continue in south-central Oklahoma. These storms will pose the greatest risk for a tornado over the next 1-2 hours. Eventually, storm interactions and the approaching line from the west will lead to a less discrete mode with time. However, KINX VAD and the low-level jet expected to remain in eastern Oklahoma suggest some continued risk for tornadoes with line embedded supercells or QLCS circulations. Within the line itself, there are embedded bowing segments noted on regional radar. These elements will pose a risk for damaging winds. Convective trends will continue to be monitored for possible watch extensions storms progress eastward this evening. The very moist environment and anticipated low-level shear will remain favorable. ..Wendt.. 06/03/2025 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...TSA...OUN...

Scattered severe thunderstorms remain possible from the southern Great Plains to the Midwest. ...01z Update... Low-amplitude short-wave trough is ejecting across eastern KS/OK into extreme northern TX. A considerable amount of convection has evolved ahead of this feature, just ahead of the synoptic front this is now surging southeast across southeast KS-central OK-TX south Plains. Complex storm modes are noted along the corridor of pre frontal convection, with a mix of a few supercells, clusters, and bowing line segments. Seasonally strong instability has yet to be overturned ahead of this activity with 2000-3000 J/kg SBCAPE extending as far northeast as the MO Ozarks. 00z sounding from SGF supports this with 2600 J/kg SBCAPE and 0-6km bulk shear around 30kt. Additionally, lapse rates are not that steep and CINH is negligible, so widespread convection should spread east and southeast ahead of this boundary through this evening. Buoyancy is quite a bit weaker across northern IL into southern WI, but an organized QLCS is propagating northeast into this region. DVN sounding exhibits around 40kt 0-6km shear, so this activity is expected to remain organized for the next several hours despite the poor lapse rates and modest instability. ..Darrow.. 06/04/2025 Read more
