MD 1731 CONCERNING SEVERE THUNDERSTORM WATCH 579... FOR EASTERN ARKANSAS...NORTHERN MISSISSIPPI...NORTHERN ALABAMA...NORTHERN GEORGIA...AND THE SOUTHERN HALF OF TENNESSEE
Mesoscale Discussion 1731 NWS Storm Prediction Center Norman OK 0655 PM CDT Tue Aug 13 2019 Areas affected...eastern Arkansas...northern Mississippi...northern Alabama...northern Georgia...and the southern half of Tennessee Concerning...Severe Thunderstorm Watch 579... Valid 132355Z - 140100Z The severe weather threat for Severe Thunderstorm Watch 579 continues. SUMMARY...An isolated severe threat will gradually shift southward across the discussion area through the early evening. The probability of a new Severe Thunderstorm Watch issuance for portions of the discussion area is 20%. DISCUSSION...Scattered clusters of storms continue to persist across the remaining valid portions of WW 579, with other marginally severe convection in eastern Arkansas. More recently, scattered storms have begun to develop across western Tennessee between these two clusters of storms along a slowly southward-moving front across the area. These storms are in a weakly sheared, yet strongly unstable environment, which should continue to support isolated instances of gusty winds and marginally severe hail. Storms have drifted southward across the discussion area and should continue to do so through slightly after dusk, when nocturnal boundary layer cooling results in a decrease in overall updraft intensity. Furthermore, western Tennessee convection may continue to expand and grow upscale with time, posing a wind/hail risk into northern Mississippi over the next couple hours. On the whole, these convective trends will probably not necessitate a new WW issuance. ..Cook.. 08/13/2019 ...Please see www.spc.noaa.gov for graphic product...

WW 578 SEVERE TSTM NC VA CW 131900Z - 140100Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 578 NWS Storm Prediction Center Norman OK 300 PM EDT Tue Aug 13 2019 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Central and eastern North Carolina Southeast Virginia Coastal Waters * Effective this Tuesday afternoon and evening from 300 PM until 900 PM EDT. * Primary threats include...

URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 579 NWS Storm Prediction Center Norman OK 250 PM CDT Tue Aug 13 2019 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Middle and southeast Tennessee * Effective this Tuesday afternoon and evening from 250 PM until 900 PM CDT. * Primary threats include... Scattered damaging wind gusts to 70 mph possible Isolated large hail events to 1.5 inches in diameter possible SUMMARY...Scattered thunderstorms developing across middle Tennessee may intensify as they consolidate into an east-southeast moving cluster towards southeast Tennessee. The severe thunderstorm watch area is approximately along and 55 statute miles north and south of a line from 50 miles south southwest of Clarksville TN to 25 miles east southeast of Crossville TN.

MD 1730 CONCERNING SEVERE POTENTIAL...SEVERE THUNDERSTORM WATCH LIKELY FOR CENTRAL AND SOUTHWEST KS...FAR EAST-CENTRAL CO
Mesoscale Discussion 1730 NWS Storm Prediction Center Norman OK 0522 PM CDT Tue Aug 13 2019 Areas affected...central and southwest KS...far east-central CO Concerning...Severe potential...Severe Thunderstorm Watch likely Valid 132222Z - 132345Z Probability of Watch Issuance...80 percent SUMMARY...Storms will probably develop south-southeastward into west-central and southwest KS this evening. Severe gusts (60-75mph) and isolated large hail are the primary threats. DISCUSSION...Radar mosaic shows a couple of intense storm clusters near the Burlington, CO/Goodland KS vicinity and another farther northeast in between Colby, KS and McCook, NE. A considerable amount of outflow associated with the storms is becoming more spatially extensive with time. Surface analysis indicates temperatures in the upper 80s with middle 60s degrees F dewpoints south of the ongoing storms. Recent storm-scale model guidance suggests a continuation of storms through the evening as this activity moves to the south-southeast. The eastern periphery of steeper 700-500mb lapse rates (7.5 degrees C/km) is located over western KS with 8-9 degree C/km 0-3km lapse rates. Despite some slow cooling early this evening, mature cold pools and regenerative development will probably lead to storms moving towards the Garden City/Dodge City vicinity later this evening. The hail risk may focus over west-central KS before additional linear upscale growth favors mostly a risk for severe gusts. ..Smith/Edwards.. 08/13/2019 ...Please see www.spc.noaa.gov for graphic product...

MD 1729 CONCERNING SEVERE THUNDERSTORM WATCH 579... FOR MIDDLE AND EASTERN TENNESSEE
Mesoscale Discussion 1729 NWS Storm Prediction Center Norman OK 0509 PM CDT Tue Aug 13 2019 Areas affected...Middle and eastern Tennessee Concerning...Severe Thunderstorm Watch 579... Valid 132209Z - 132315Z The severe weather threat for Severe Thunderstorm Watch 579 continues. SUMMARY...The severe threat continues across WW 579. DISCUSSION...Scattered strong to severe thunderstorms continue across mainly northern and central portions of ongoing WW 579 at this time. These storms are loosely organized and in a marginally strong shear environment, though strong instability (3500-5000 J/kg MUCAPE) continues to support occasional wind-damage-producing downbursts with mostly outflow-dominant storms. Observations and short-term model guidance suggests that these storms should continue to gradually grow upscale over the next few hours, with the severe threat tapering off from north to south as overturning and maturing cold-pool processes continue. ..Cook.. 08/13/2019 ...Please see www.spc.noaa.gov for graphic product...
