MD 0739 CONCERNING SEVERE THUNDERSTORM WATCH 224... FOR PORTIONS OF CENTRAL INTO EASTERN TEXAS
Mesoscale Discussion 0739 NWS Storm Prediction Center Norman OK 0937 PM CDT Thu May 09 2024 Areas affected...portions of central into eastern Texas Concerning...Severe Thunderstorm Watch 224... Valid 100237Z - 100330Z The severe weather threat for Severe Thunderstorm Watch 224 continues. SUMMARY...The severe threat continues across Severe Thunderstorm Watch 224. Severe wind and hail remains the primary concern, particularly with the more dominant supercell updrafts. DISCUSSION...Two supercell thunderstorms with a history of very large hail and severe wind gusts continue to move southward over central/south-central TX, while a cluster of severe storms across eastern TX may be growing upscale into an MCS. These storms continue to progress amid a highly unstable and sheared environment. Though nocturnal cooling will contribute to a gradual decline of the severe threat, the degree of remaining instability suggests that severe wind and hail should accompany the ongoing storms for at least a few more hours. Should discrete supercell modes prevail, large hail will remain the main threat, with severe gusts becoming the dominant threat with any clusters that grow upscale. ..Squitieri.. 05/10/2024 ...Please see www.spc.noaa.gov for graphic product...

WW 224 SEVERE TSTM LA TX 092245Z - 100500Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 224 NWS Storm Prediction Center Norman OK 545 PM CDT Thu May 9 2024 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of West Central Louisiana Central and East Texas * Effective this Thursday afternoon from 545 PM until Midnight 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 3 inches in diameter likely A tornado or two possible SUMMARY...Isolated supercell thunderstorms over central Texas will track eastward and become more numerous through the evening, spreading across the watch area. Very large hail and perhaps a tornado are the main threats early, with an increasing risk of damaging winds by late evening. The severe thunderstorm watch area is approximately along and 40 statute miles either side of a line from 75 miles west of Austin TX to 105 miles east northeast of Lufkin TX. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU4). PRECAUTIONARY/PREPAREDNESS ACTIONS... REMEMBER...A Severe Thunderstorm Watch means conditions are favorable for severe thunderstorms in and close to the watch area.

MD 0738 CONCERNING SEVERE THUNDERSTORM WATCH 222...224... FOR PORTIONS OF CENTRAL AND EASTERN TEXAS INTO WESTERN AND NORTHERN LOUISIANA
Mesoscale Discussion 0738 NWS Storm Prediction Center Norman OK 0803 PM CDT Thu May 09 2024 Areas affected...portions of central and eastern Texas into western and northern Louisiana Concerning...Severe Thunderstorm Watch 222...224... Valid 100103Z - 100230Z The severe weather threat for Severe Thunderstorm Watch 222, 224 continues. SUMMARY...The severe threat continues across Severe Thunderstorm Watches 222 and 224. Severe winds and hail remain the primary threats. Conditions are being monitored for upscale growth into a bow echo and accompanying risk of a greater damaging wind threat. DISCUSSION...Multiple supercells with a history of producing severe hail (up to 4 inches in some cases) and isolated damaging gusts continue to progress southeast over central TX. These storms are impinging on a zonal baroclinic boundary, where additional storms have recently initiated. Given 4500+ J/kg MLCAPE and 50-70 kts of effective bulk shear in place, any supercells that remain discrete will continue to pose a damaging gust and large hail risk, including stones exceeding 2 inches in diameter. Of greater concern is the possibility of upscale growth into an organized bow-echo MCS, which could produce an appreciable swath of severe gusts (including those exceeding 75 mph) upon development. However, intense bow-echo development is conditional upon efficient cold pool mergers and the progressive cold pool boundary (convective leading line) becoming oriented roughly normal to the deep-layer shear vector. The latest high resolution model guidance, including the last few runs of the HRRR and Warn-on-Forecast ensemble output, lean against this scenario. Nonetheless, should storms remain more discrete, high-resolution guidance still suggests that at least some severe wind potential will continue into the evening hours, and a couple of 75+ mph gusts could still occur. ..Squitieri.. 05/10/2024 ...Please see www.spc.noaa.gov for graphic product...

WW 222 SEVERE TSTM AR LA OK TX 092050Z - 100400Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 222 NWS Storm Prediction Center Norman OK 350 PM CDT Thu May 9 2024 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Southern Arkansas Northern Louisiana Southeast Oklahoma Northeast Texas * Effective this Thursday afternoon and evening from 350 PM until 1100 PM CDT. * 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 likely A tornado or two possible SUMMARY...Clusters of supercells and eventual linear segments, including the possibility for bows, will gradually move west to east across the Watch area late this afternoon through the evening. Large to very large hail and severe gusts will be possible through at least the early evening, before upscale growth and the risk for wind damage and perhaps a tornado or two accompanies linear storm modes. The severe thunderstorm watch area is approximately along and 80 statute miles north and south of a line from 40 miles south of Durant OK to 45 miles north of Monroe LA. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU2). PRECAUTIONARY/PREPAREDNESS ACTIONS...

MD 0737 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR SOUTHEASTERN OHIO AND WEST VIRGINIA
Mesoscale Discussion 0737 NWS Storm Prediction Center Norman OK 0700 PM CDT Thu May 09 2024 Areas affected...southeastern Ohio and West Virginia Concerning...Severe potential...Watch unlikely Valid 100000Z - 100200Z Probability of Watch Issuance...20 percent SUMMARY...Local/isolated risk for strong wind gusts will persist for a few hours. WW not anticipated. DISCUSSION...Latest radar shows an uptick in convection from southern Ohio to northern West Virginia, in the vicinity of a southeastern Ohio surface low, and attendant baroclinic zones. Ahead of the front, RAP-based objective analysis suggests that diurnal heating has pushed mixed-layer CAPE to near 1000 J/kg across the Ohio River Valley area, which is contributing to the convective uptick, ahead of the mid-level vort max crossing Lake Erie/Ohio at this time. Moderately strong west-northwesterly flow through the lower and middle troposphere is indicated across this region, which may support some additional, small-scale convective organization. Attendant severe risk -- primarily in the form of locally gusty/damaging winds with stronger convective elements -- will likely continue for the next 2 to 3 hours. Thereafter, as nocturnal cooling commences, severe risk is expected to gradually diminish. As such, limited risk -- both in temporally and in terms of magnitude -- will likely preclude any need for WW issuance. ..Goss/Hart.. 05/10/2024 ...Please see www.spc.noaa.gov for graphic product...
