    WW 616 TORNADO CO KS NE 242225Z - 250500Z URGENT - IMMEDIATE BROADCAST REQUESTED Tornado Watch Number 616 NWS Storm Prediction Center Norman OK 525 PM CDT Sat Aug 24 2019 The NWS Storm Prediction Center has issued a * Tornado Watch for portions of Far eastern Colorado Western and central Kansas Southwest Nebraska * Effective this Saturday afternoon from 525 PM until Midnight CDT. * Primary threats include... A couple tornadoes possible Scattered large hail and isolated very large hail events to 2.5 inches in diameter likely Scattered damaging winds likely with isolated significant gusts to 75 mph possible SUMMARY...Severe thunderstorms are expected to develop and increase initially across southwest Nebraska, northwest Kansas, and also southwest Kansas through early evening. Supercells capable of very large hail can be expected. The possibility of a couple of tornadoes will also increase through the early/mid-evening hours, particularly across a broad part of western toward north-central Kansas. Damaging winds will also be an increasing concern later this evening as an organized thunderstorm cluster likely evolves and spreads southeastward across northwest/central Kansas. The tornado watch area is approximately along and 110 statute miles north and south of a line from 20 miles south of Burlington CO to 30 miles southeast of Russell KS. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU6). 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. && AVIATION...Tornadoes and a few severe thunderstorms with hail surface and aloft to 2.5 inches. Extreme turbulence and surface wind gusts to 65 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 32020. ...Guyer Read mor […]

    WW 617 SEVERE TSTM NM OK TX 242250Z - 250600Z URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 617 NWS Storm Prediction Center Norman OK 550 PM CDT Sat Aug 24 2019 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Northeast New Mexico Oklahoma Panhandle Texas Panhandle * Effective this Saturday afternoon and Sunday morning from 550 PM until 100 AM CDT. * Primary threats include... Scattered large hail and isolated very large hail events to 2 inches in diameter possible Scattered damaging wind gusts to 70 mph possible A tornado or two possible SUMMARY...Isolated storms moving into far northeast New Mexico and the Oklahoma Panhandle should further intensify while other storms develop through the evening. Large hail should be the primary risk, but a tornado cannot be ruled out, particularly during the early/mid-evening hours as a low-level jet increases across the region. Damaging wind potential could also increase if an organized cluster evolves as storms progress southeastward. The severe thunderstorm watch area is approximately along and 50 statute miles north and south of a line from 25 miles west southwest of Clayton NM to 85 miles east northeast of Borger TX. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU7). 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 616... AVIATION...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. Mean storm motion vector 32020. ...Guyer Read mor […]

    MD 1850 CONCERNING SEVERE THUNDERSTORM WATCH 617... FOR THE TEXAS AND OKLAHOMA PANHANDLE REGION Mesoscale Discussion 1850 NWS Storm Prediction Center Norman OK 0909 PM CDT Sat Aug 24 2019 Areas affected...the Texas and Oklahoma Panhandle region Concerning...Severe Thunderstorm Watch 617... Valid 250209Z - 250415Z The severe weather threat for Severe Thunderstorm Watch 617 continues. SUMMARY...Severe risk is expected to increase across portions of the WW area in the next couple of hours. DISCUSSION...While storms which developed earlier across southeast Colorado have diminished, new convective development is ongoing over southwestern Kansas, with storms moving south-southeastward. The convection is occurring in response to a strengthening low-level jet, and as such, it appears possible that some of this convection will affect portions of WW 617 in the next couple of hours. The main risk with this convection, assuming the expected upscale growth, would be locally damaging wind gusts. ..Goss.. 08/25/2019 ...Please see www.spc.noaa.gov for graphic product...

    MD 1849 CONCERNING TORNADO WATCH 616... FOR WESTERN KANSAS AND ADJACENT PORTION OF SOUTHWESTERN NEBRASKA Mesoscale Discussion 1849 NWS Storm Prediction Center Norman OK 0839 PM CDT Sat Aug 24 2019 Areas affected...western Kansas and adjacent portion of southwestern Nebraska Concerning...Tornado Watch 616... Valid 250139Z - 250345Z The severe weather threat for Tornado Watch 616 continues. SUMMARY...Severe risk is increasing at this time across Tornado Watch 616 -- including potential for an isolated tornado. DISCUSSION...Latest radar loop shows a noted increase in convection over the past hour across western Kansas, which is correlated with the beginnings of an observed increase in low-level flow. As the jet continues to strengthen this evening, and given the moist/moderately unstable airmass in place across this region, a continuation of this convective increase is expected. While storms remain isolated, and continue to exhibit supercell structures, an isolated tornado remains possible, along with locally damaging winds and large hail. With time, wind risk is expected to increase, as upscale growth of convection into an MCS continues to appear likely. ..Goss.. 08/25/2019 ...Please see www.spc.noaa.gov for graphic product...

    SPC 0100Z Day 1 Outlook Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0747 PM CDT Sat Aug 24 2019 Valid 250100Z - 251200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS WESTERN AND CENTRAL KS INTO NORTHERN OK... ...SUMMARY... The greatest severe-storm threat this evening into tonight is from central and western Kansas into northern Oklahoma, with severe wind, damaging hail and a few tornadoes possible. ...KS and OK vicinity this evening and tonight... A mid-level low/shortwave trough evident on water vapor imagery this evening will slowly move eastward across KS through early Sunday morning. An associated mid-level cold pocket and a moist boundary layer has resulted in a moderate buoyancy (1500 J/kg MLCAPE) per the Dodge City evening raob. Models show storm development to increase primarily after sunset across western/central KS as a southerly LLJ strengthens. Upscale growth into an eventual cluster or two is expected over KS before moving southeast into OK late tonight into early Sunday morning. Hail/wind will be the primary risks with the activity this evening into the overnight hours. ...ND this evening... A surface trough located near the ND/MT border is serving as a focus for thunderstorm development this evening. Adequate instability east of the surface trough may foster a couple of strong storms this evening before gradual boundary layer stabilization limits overall storm intensity by late evening. ..Smith.. 08/25/2019 Read mor […]
