WW 593 SEVERE TSTM IA MN NE SD 172315Z - 180600Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 593 NWS Storm Prediction Center Norman OK 615 PM CDT Sat Aug 17 2019 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Northwest Iowa Southwest Minnesota Northeast Nebraska Eastern South Dakota * Effective this Saturday night and Sunday morning from 615 PM until 100 AM CDT. * Primary threats include... Scattered damaging winds likely with isolated significant gusts to 75 mph possible Scattered large hail and isolated very large hail events to 2 inches in diameter possible A tornado or two possible SUMMARY...Ongoing storms across south-central/northeast South Dakota early this evening will continue eastward, with the possibility of additional/more isolated supercell development ahead of an evolving cluster of storms. Some tornado risk may exist for a time, particularly through mid-evening across southeast South Dakota. However, the overall most common risks should be large hail and damaging winds, which should become more of a concern later this evening as storm mergers occur and a more organized cluster/line develops. The severe thunderstorm watch area is approximately along and 130 statute miles north and south of a line from 30 miles north northeast of Worthington MN to 45 miles west southwest of Huron SD. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU3). 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 590...WW 591...WW 592... AVIATION...A few severe thunderstorms with hail surface and aloft to 2 inches. Extreme turbulence and surface wind gusts to 65 knots. A few cumulonimbi with maximum tops to 600. Mean storm motion vector 28025. ...Guyer Read more

MD 1781 CONCERNING SEVERE THUNDERSTORM WATCH 594... FOR PORTIONS OF CENTRAL/SOUTHEASTERN KS
Mesoscale Discussion 1781 NWS Storm Prediction Center Norman OK 1106 PM CDT Sat Aug 17 2019 Areas affected...Portions of central/southeastern KS Concerning...Severe Thunderstorm Watch 594... Valid 180406Z - 180530Z The severe weather threat for Severe Thunderstorm Watch 594 continues. SUMMARY...An extension in area for Severe Thunderstorm Watch 594 into southeastern KS may be needed for a severe/damaging wind gust threat. DISCUSSION...A small thunderstorm cluster that strengthened from northwestern into north-central KS over the past few hours has produced multiple measured severe wind gusts across this region. Latest radar imagery shows this activity moving quickly southeastward around 40-45 kt from central into southeastern KS. Strong inbound velocities have been observed with these storms from the KICT radar, and VWP wind profile estimates show a 35-40 kt south-southwesterly low-level jet is present across this region. The airmass across southeastern KS remains strongly unstable this evening, with MLCAPE generally ranging from 3000-4000 J/kg. Even with some diurnal cooling and related convective inhibition, severe/damaging wind gusts potentially up to 60-70 mph will probably remain a threat with southeastward extent. Accordingly, an extension in area for Severe Thunderstorm Watch 594 may be needed into parts of southeastern KS. ..Gleason/Guyer.. 08/18/2019 ...Please see www.spc.noaa.gov for graphic product...

MD 1780 CONCERNING SEVERE THUNDERSTORM WATCH 593...595... FOR PORTIONS OF FAR SOUTHEASTERN SD...SOUTHERN MN...NORTHEASTERN NE...AND NORTHERN IA
Mesoscale Discussion 1780 NWS Storm Prediction Center Norman OK 1032 PM CDT Sat Aug 17 2019 Areas affected...Portions of far southeastern SD...southern MN...northeastern NE...and northern IA Concerning...Severe Thunderstorm Watch 593...595... Valid 180332Z - 180500Z The severe weather threat for Severe Thunderstorm Watch 593, 595 continues. SUMMARY...A strong to damaging wind threat may continue eastward out of Severe Thunderstorm Watch 593 this evening. A new watch has been issued into southern Minnesota and northern Iowa to address this potential. DISCUSSION...A well-organized but small bowing thunderstorm cluster is progressing east-southeastward around 40 kt across far southeastern SD as of 0330Z. Multiple strong to severe wind gusts of 55-65 mph have been measured by various observing sites across this area over the past couple of hours, with KFSD reporting a gust to 47 mph at 0306Z. Although instability gradually decreases with eastward extent into southern MN and north-central IA, a modestly enhanced southwesterly low-level jet should aid continued storm organization and intensity through the remainder of the evening and into the early overnight hours. Given the ongoing linear convective mode, strong to damaging winds will likely remain the primary threat. Additional convective development along a cold front may occur into parts of northeastern NE into northwestern and west-central IA. ..Gleason/Guyer.. 08/18/2019 ...Please see www.spc.noaa.gov for graphic product...

WW 592 SEVERE TSTM CO KS NE 172035Z - 180400Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 592 NWS Storm Prediction Center Norman OK 335 PM CDT Sat Aug 17 2019 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Far eastern Colorado Northwest Kansas Far southwestern Nebraska * Effective this Saturday afternoon and evening from 335 PM until 1100 PM CDT. * Primary threats include... Scattered damaging winds and isolated significant gusts to 80 mph possible Isolated very large hail events to 2 inches in diameter possible SUMMARY...A cluster of severe thunderstorms may develop off across the tri-state area as high-based storms spread east from the Palmer Divide in Colorado. The severe thunderstorm watch area is approximately along and 60 statute miles north and south of a line from 35 miles west northwest of Burlington CO to 55 miles southeast of Mccook NE. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU2). PRECAUTIONARY/PREPAREDNESS ACTIONS...

MD 1779 CONCERNING SEVERE THUNDERSTORM WATCH 592... FOR NORTHWEST KANSAS AND VICINITY
Mesoscale Discussion 1779 NWS Storm Prediction Center Norman OK 0910 PM CDT Sat Aug 17 2019 Areas affected...northwest Kansas and vicinity Concerning...Severe Thunderstorm Watch 592... Valid 180210Z - 180415Z The severe weather threat for Severe Thunderstorm Watch 592 continues. SUMMARY...The strongest storm has moved out of WW592 into WW594. Elevated storms have redeveloped across Kit Carson, Sherman, and Thomas counties and may pose a low-end severe threat in the next hour or two. DISCUSSION...Temperatures and dewpoints dropped across northeast Colorado and northwest Kansas as storms passed through the area earlier this evening with low-level stable conditions present. However, some forcing for ascent aloft has helped elevated storms redevelop across far eastern Colorado and northwest Kansas along the I-70 corridor. MUCAPE of 1500-3000 J/kg and marginal effective bulk shear could result in isolated, low-end severe hail and possibly damaging wind if it can penetrate the low-level stable layer. GLD VAD shows north-northeast winds at low-levels indicating limited warm air advection/isentropic lift associated with the low-level jet that is beginning to strengthen across the southern/central Plains. Overall, the potential for severe hail/wind is limited across WW592 before it expires at 04z, but a strong storm or two is possible. ..Nauslar/Guyer.. 08/18/2019 ...Please see www.spc.noaa.gov for graphic product...
