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... 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... AVIATION...A few severe thunderstorms with hail surface and aloft to 2 inches. Extreme turbulence and surface wind gusts to 70 knots. A few cumulonimbi with maximum tops to 500.

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...

MD 1778 CONCERNING SEVERE THUNDERSTORM WATCH 593... FOR PORTIONS OF EASTERN SD INTO WEST-CENTRAL AND SOUTHWESTERN MN...FAR NORTHEASTERN NE...AND FAR NORTHWESTERN IA
Mesoscale Discussion 1778 NWS Storm Prediction Center Norman OK 0826 PM CDT Sat Aug 17 2019 Areas affected...Portions of eastern SD into west-central and southwestern MN...far northeastern NE...and far northwestern IA Concerning...Severe Thunderstorm Watch 593... Valid 180126Z - 180300Z The severe weather threat for Severe Thunderstorm Watch 593 continues. SUMMARY...Severe/damaging wind gusts will likely become an increasing concern across Severe Thunderstorm Watch 593 this evening. Relatively greater severe wind potential should exist across southeastern SD and vicinity in the short term (next few hours). DISCUSSION...A line of storms has congealed along a cold front this evening across eastern SD into parts of west-central MN. The southern flank of this line across southeastern SD appears to be more robust, as strong instability (MLCAPE of 2500-3500 J/kg) is present across this region. A 30-35 kt southwesterly low-level jet is expected to strengthen over eastern NE into southeastern SD and vicinity, which will likely maintain storm intensity through the remainder of the evening. Strong inbound velocities have recently been noted on the KFSD radar with storms approaching Sioux Falls SD, with evidence of a rear inflow jet developing. A corridor of severe, damaging winds with gusts of 60-75 mph appears increasingly likely across southeastern SD and vicinity. Isolated large hail may also occur with supercells embedded within the line. Farther north, isolated damaging winds will remain possible into west-central/southwestern MN, but instability does decrease with northward extent across Severe Thunderstorm Watch 593. ..Gleason.. 08/18/2019 ...Please see www.spc.noaa.gov for graphic product...

Scattered severe thunderstorms with damaging winds and large hail as the primary threats are expected tonight across a large portion of the northern to central Great Plains into the Midwest. ...01Z Update... ...Northern/Central Plains into the Mid MS Valley... Strong to severe thunderstorms are expected to persist along southern portions cold front currently extending from north-central MN southwestward into the NE Panhandle. Air mass ahead of the cold front is characterized by very moist low-levels (i.e. surface dewpoints in the 70s across eastern SD), steep mid-level lapse rates, and very strong buoyancy (i.e. MLCAPE over 3000 J/kg). Given the linear forcing, a linear storm mode remains favored with strong wind gusts as the primary severe threat. Additionally, storm cluster across south-central SD has recently shown a surge in forward motion, suggesting more forward-propagation off the front may be occurring. Farther south (across northern KS and far southern NE), a discrete storm continues to progress eastward across Sheridan County. Potential exists for this storm become more organized and strengthen as it continues eastward into more favorable low-level moisture and a strengthening low-level jet. Additionally, overall storm coverage is expected to increase ahead of this storm as the low-level jet increases. ...Far Northwest TX....Southwest/South-Central OK...
