WW 556 SEVERE TSTM ND SD 061950Z - 070400Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 556 NWS Storm Prediction Center Norman OK 250 PM CDT Tue Aug 6 2019 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of central and southern North Dakota northern South Dakota * Effective this Tuesday afternoon and evening from 250 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 possible A tornado or two possible SUMMARY...Severe storms are expected to increase in coverage this afternoon and continue into the evening. Initial primary threat will be supercells with large to very large hail and downburst winds, though a brief tornado cannot be ruled out. Threat will transition to damaging wind as storms develop southeast into South Dakota this evening. The severe thunderstorm watch area is approximately along and 85 statute miles east and west of a line from 15 miles east northeast of Garrison ND to 75 miles south southwest of Aberdeen SD. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU6). 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 555... AVIATION...A few severe thunderstorms with hail surface and aloft to 2.5 inches. Extreme turbulence and surface wind gusts to 60 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 31035. ...Dial Read more

MD 1656 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR MIDDLE TN...SOUTH-CENTRAL KY
Mesoscale Discussion 1656 NWS Storm Prediction Center Norman OK 0819 PM CDT Tue Aug 06 2019 Areas affected...Middle TN...South-central KY Concerning...Severe potential...Watch unlikely Valid 070119Z - 070245Z Probability of Watch Issuance...20 percent SUMMARY...Isolated damaging winds are possible until around 02-03Z with ongoing thunderstorm complex, but a gradual weakening trend is expected with time. Watch issuance is not anticipated. DISCUSSION...Consolidation of earlier thunderstorms across KY has resulted in a forward-propagating cluster moving into middle TN. KOHX radar depicts surging outflow approaching the Nashville metro area, which will result in a short-term damaging wind risk between now and at least 02Z. The 00Z BNA sounding was moderately unstable (MLCAPE ~1500 J/kg), though low-level flow was weak and deep-layer shear only marginally favorable for organized convection. With these factors in mind, a gradual weakening trend is expected with time as the boundary layer stabilizes this evening. However, some threat for damaging wind will likely continue until around the 02-03Z timeframe as the complex and associated cold pool continue southeastward across middle TN. Due to the relatively limited duration of the anticipated threat, watch issuance is not expected. ..Dean/Thompson.. 08/07/2019 ...Please see www.spc.noaa.gov for graphic product...

SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0757 PM CDT Tue Aug 06 2019 Valid 070100Z - 071200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS THIS EVENING INTO THE OVERNIGHT HOURS ACROSS PARTS OF THE NORTHERN PLAINS... ...SUMMARY... A few severe thunderstorms remain possible this evening into the overnight hours across parts of the northern Plains, mainly across parts of the central and eastern Dakotas into northern Nebraska. ...01Z Outlook Update... ...Dakotas/Nebraska... Latest observational data and model output indicate that low-level ridging remains a fairly prominent feature, centered across the mid Missouri Valley, roughly between Pierre SD and Omaha NE. Some erosion/weakening appears possible later this evening into the overnight hours, as lower/mid tropospheric warm advection strengthens across parts of south central South Dakota into northern Nebraska, well ahead of a vigorous short wave trough and deepening embedded mid-level low digging across Manitoba and northern Ontario. Scattered thunderstorm development which initiated across southwestern and central North Dakota, in response to a subtle preceding perturbation migrating around the periphery of the western U.S. mid/upper ridging, has shown recent signs of diminishing. However, the environment across western and central Nebraska into south central South Dakota, on the western periphery of the low-level ridging into weak surface troughing, remains characterized by moderate to strong potential instability (CAPE of 1500-3000 J/kg). The latest Rapid Refresh continues to suggest that new vigorous thunderstorm development is possible during the 03-06Z time frame in response to forcing for ascent with the warm advection, perhaps aided by a modest southwesterly low-level jet across the Nebraska panhandle into the central South Dakota/Nebraska border area. In the presence of strong shear beneath 30-40 kt northwesterly 500 mb flow, some of this activity may become capable of producing severe hail and strong wind gusts, with the evolution of an upscale growing and organizing cluster of thunderstorms possible overnight. ...Parts of Tennessee Valley... Instability ahead a conglomerate southward advancing, convectively generated surface cold pool, modest deep-layer shear, and perhaps forcing for ascent associated with a subtle perturbation within broadly cyclonic mid-level flow, may maintain vigorous thunderstorm activity south of the Kentucky/Tennessee border. This may be accompanied by at least some continuing risk for wind gusts approaching severe limits, across much of western and middle Tennessee through 03-05Z, before activity begins to diminish in weaker/waning instability. ..Kerr.. 08/07/2019 Read more

URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 555 NWS Storm Prediction Center Norman OK 150 PM CDT Tue Aug 6 2019 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of southern Illinois southern Indiana western Kentucky southeast Missouri * Effective this Tuesday afternoon and evening from 150 PM until 900 PM CDT. * Primary threats include... Scattered damaging wind gusts to 70 mph possible Isolated large hail events to 1 inch in diameter possible SUMMARY...Scattered multicell storms will continue to intensify within a strongly unstable environment and become capable of producing isolated damaging wind and possibly some hail through early evening. The severe thunderstorm watch area is approximately along and 80 statute miles north and south of a line from 10 miles north northwest of Farmington MO to 30 miles east northeast of Evansville IN.

MD 1655 CONCERNING SEVERE THUNDERSTORM WATCH 556... FOR FAR SOUTHERN NORTH DAKOTA INTO CENTRAL SOUTH DAKOTA AND NEBRASKA
Mesoscale Discussion 1655 NWS Storm Prediction Center Norman OK 0619 PM CDT Tue Aug 06 2019 Areas affected...far southern North Dakota into central South Dakota and Nebraska Concerning...Severe Thunderstorm Watch 556... Valid 062319Z - 070115Z The severe weather threat for Severe Thunderstorm Watch 556 continues. SUMMARY...The threat for damaging hail and wind continues, and will likely extend south of watch 556. A new watch is likely for parts of southern South Dakota into Nebraska by about 01Z. DISCUSSION...Storms that formed near the surface trough have solidified into large cells, with supercell characteristics at times. Forecast soundings show a deep layer of steep lapse rates owing to heating and cool temperatures aloft. Low-level winds are weak currently, but hodographs are quite long with strong northwest flow aloft. Ongoing storms are currently within the surface theta-e axis, which extends from the central Dakotas into central NE. East of this axis, the air mass is much less unstable near the surface high, from southeast SD across eastern NE and points east. In the near term, storms are expected to continue south/southeastward near the instability gradient, remaining mainly cellular. Very large hail and localized wind damage will be possible. Increasing southwesterly 850 mb winds this evening may aid lift into eastern SD and NE, but the warm advection profiles are not to be very pronounced. As such, the corridor of maximum threat should generally extend south/southeast from the ongoing storm cluster near the MO River in central SD. ..Jewell.. 08/06/2019 ...Please see www.spc.noaa.gov for graphic product...
