WW 31 SEVERE TSTM OK TX 072100Z - 080400Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 31 NWS Storm Prediction Center Norman OK 300 PM CST Thu Mar 7 2024 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Western Oklahoma West-central and western North Texas * Effective this Thursday afternoon and evening from 300 PM until 1000 PM CST. * Primary threats include... Scattered large hail likely with isolated very large hail events to 2.5 inches in diameter possible Scattered damaging wind gusts to 70 mph possible A tornado or two possible SUMMARY...Thunderstorms are slowly intensifying in vicinity of a dryline over western Oklahoma and west Texas. This activity will track eastward through the afternoon and early evening, posing a risk of large hail and damaging winds. The severe thunderstorm watch area is approximately along and 55 statute miles east and west of a line from 20 miles south of San Angelo TX to 40 miles east northeast of Alva OK. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU1). 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... AVIATION...A few severe thunderstorms with hail surface and aloft to 2.5 inches. Extreme turbulence and surface wind gusts to 60 knots. A few cumulonimbi with maximum tops to 450. Mean storm motion vector 26030. ...Hart Read more

MD 0201 CONCERNING SEVERE THUNDERSTORM WATCH 30... FOR NORTHERN OKLAHOMA AND SOUTHERN KANSAS
Mesoscale Discussion 0201 NWS Storm Prediction Center Norman OK 0637 PM CST Thu Mar 07 2024 Areas affected...northern Oklahoma and southern Kansas Concerning...Severe Thunderstorm Watch 30... Valid 080037Z - 080200Z The severe weather threat for Severe Thunderstorm Watch 30 continues. SUMMARY...Severe threat continues within WW30. Isolated tornado potential near the OK/KS border. DISCUSSION...Storm activity is ongoing across northern Oklahoma into southern Kansas along an eastward advancing dry line and warm front draped across southern Kansas. Two supercells located along surface warm front have shown better organization as they move eastward into dew points in the upper 50s. A narrow corridor near the warm front may support risk of an isolated tornado before storms cross to the cool side of the boundary, given enhanced vorticity along the front. Further west along the dry line, storms will likely cluster and attempt to grow up scale as the cold front moves east eventually overtaking the dry line. The main threats will likely be wind and hail with the linear storm modes. ..Thornton/Thompson.. 03/08/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...TSA...ICT...OUN...

MD 0200 CONCERNING SEVERE THUNDERSTORM WATCH 31... FOR SOUTHERN HIGH PLAINS
Mesoscale Discussion 0200 NWS Storm Prediction Center Norman OK 0600 PM CST Thu Mar 07 2024 Areas affected...Southern High Plains Concerning...Severe Thunderstorm Watch 31... Valid 080000Z - 080200Z The severe weather threat for Severe Thunderstorm Watch 31 continues. SUMMARY...Hail continues to be the primary risk with storms this evening. DISCUSSION...Scattered thunderstorms, a few supercells, persist across ww31. This activity continues to evolve along the eastern plume of steeper lapse rates that extend across the southern High Plains of west TX into northern OK. While large-scale forcing is not particularly noteworthy, low-level convergence is more than adequate for renewed development east of the dryline, extending northeast along the synoptic front over OK. Hail has been the most common severe threat with this activity, and radar data suggests the most robust updrafts are generating hail in excess of 1 inch. Over the last hour or so, convection has gradually increased along the synoptic front from north of CDS to near PNC. This corridor may become more concentrated into the mid-evening hours as the boundary advances slowly southeast. ..Darrow.. 03/08/2024 ...Please see www.spc.noaa.gov for graphic product...

Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0654 PM CST Thu Mar 07 2024 Valid 080100Z - 081200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS TONIGHT ACROSS PARTS OF CENTRAL AND NORTHWESTERN TEXAS...SOUTHWEST THROUGH NORTHEAST OKLAHOMA AND PARTS OF SOUTHEASTERN KANSAS... ...SUMMARY... Scattered strong thunderstorms may continue to impact portions of the southern Great Plains tonight, posing primarily a risk for severe hail and locally strong gusts. ...01Z Update... Cold air continues to nose southward through the high plains, and may advance through much of the Texas South Plains by late tonight, while advancing more slowly southeastward across the Upper Midwest, and middle into lower Missouri Valley. A weak wave has evolved along the front and is forecast to migrate from southeastern Kansas into the lower Missouri Valley overnight, but with little further development. Otherwise, generally broad, weak surface troughing likely will slowly shift eastward across the southern Great Plains toward the lower Mississippi Valley. Approaching large-scale mid-level troughing remains largely west of the southern Rockies, with the lead of two primary embedded short wave perturbations still progressing across Arizona and not likely to impact the southern Great Plains until late tonight. However, the leading edge of relative cool air in mid/upper levels has contributed to a narrow corridor of modest destabilization near/east of the Texas South Plains into southwestern through north central Oklahoma. This is near the northwestern periphery of broad mid/upper subtropical ridging still overspreading the southern Great Plains into lower Mississippi Valley. Residual warm layers aloft probably have continued to impact severe weather potential with ongoing convective development across much of central/north central Texas. This does not appear likely to change soon, but with increasing forcing associated with the approaching short wave impulse, various model output suggests increasing risk for strong/severe thunderstorm development could commence near/north of the Texas Edwards Plateau vicinity toward 07-08z, before spreading toward the Interstate 35 corridor through daybreak. Farther north, a couple of small supercell structures have developed near the frontal wave, while stronger convection has otherwise evolved into a narrow organizing line within the instability axis across southwestern into north central Oklahoma. It appears that this activity could remain fairly vigorous another couple of hours, posing a risk for mainly severe hail and locally strong surface gusts, before the instability wanes with continued boundary-layer cooling. ..Kerr.. 03/08/2024 Read more

Approaching large-scale mid-level troughing remains largely west of the southern Rockies, with the lead of two primary embedded short wave perturbations still progressing across Arizona and not likely to impact the southern Great Plains until late tonight. However, the leading edge of relative cool air in mid/upper levels has contributed to a narrow corridor of modest destabilization near/east of the Texas South Plains into southwestern through north central Oklahoma. This is near the northwestern periphery of broad mid/upper subtropical ridging still overspreading the southern Great Plains into lower Mississippi Valley. Residual warm layers aloft probably have continued to impact severe weather potential with ongoing convective development across much of central/north central Texas. This does not appear likely to change soon, but with increasing forcing associated with the approaching short wave impulse, various model output suggests increasing risk for strong/severe thunderstorm development could commence near/north of the Texas Edwards Plateau vicinity toward 07-08z, before spreading toward the Interstate 35 corridor through daybreak. Farther north, a couple of small supercell structures have developed near the frontal wave, while stronger convection has otherwise evolved into a narrow organizing line within the instability axis across southwestern into north central Oklahoma. It appears that this activity could remain fairly vigorous another couple of hours, posing a risk for mainly severe hail and locally strong surface gusts, before the instability wanes with continued boundary-layer cooling. ..Kerr.. 03/08/2024 Read more
