WW 564 TORNADO SD 091910Z - 100200Z
URGENT - IMMEDIATE BROADCAST REQUESTED Tornado Watch Number 564 NWS Storm Prediction Center Norman OK 210 PM CDT Fri Aug 9 2019 The NWS Storm Prediction Center has issued a * Tornado Watch for portions of South Dakota * Effective this Friday afternoon and evening from 210 PM until 900 PM CDT. * Primary threats include... A few tornadoes likely with a couple intense tornadoes possible Scattered damaging winds and isolated significant gusts to 80 mph likely Scattered large hail and isolated very large hail events to 2 inches in diameter possible SUMMARY...Supercells developing across west-central South Dakota should spread east-southeast across much of the central portion of the state before developing into a cluster towards eastern South Dakota. The tornado watch area is approximately along and 75 statute miles north and south of a line from 65 miles west of Pierre SD to 10 miles north northeast of Mitchell SD. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU4). 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 inches. Extreme turbulence and surface wind gusts to 70 knots. A few cumulonimbi with maximum tops to 550. Mean storm motion vector 29030. ...Grams Read more

SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0754 PM CDT Fri Aug 09 2019 Valid 100100Z - 101200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS OVER SOUTHERN SOUTH DAKOTA INTO NORTHEAST NEBRASKA...AND OVER NORTHERN OREGON... ...SUMMARY... Severe storms remain possible across parts of southeast South Dakota into northeast Nebraska with damaging winds and perhaps a brief tornado. Isolated severe wind gusts or marginal hail are also possible across northern Oregon this evening. ...Northern Plains... A cluster of storms/MCS with embedded midlevel rotation is propagating east/southeast across the SD/NE border, likely producing damaging winds and hail. Northwest winds aloft along with a southwesterly low-level jet increasing to 40 kt will continue to support this complex as it moves wholly into NE. Veering winds with height may support a brief tornado for the more cellular parts of the complex, but the tendency for merged outflows will maximize damaging wind potential. ...Northern Oregon... Scattered storms persist across much of central and eastern Oregon and into southwest Idaho and northern Nevada, beneath cold temperatures aloft as the upper low moves ashore. Pockets of steep low-level lapse rates ahead of any storms will foster strong outflow winds, possibly damaging. Moisture content is maximized over northern Oregon, and this may favor marginal hail at times as storms move into that area. ..Jewell.. 08/10/2019 Read more

DISCUSSION...Large-scale forcing ahead of short-wave trough is spreading north across OR early this evening. Scattered strong convection has developed ahead of this feature which is now spreading across northern-eastern portions of the State. As drying surges north, robust thunderstorms are expected to spread into northeast OR over the next few hours.

MD 1682 CONCERNING SEVERE POTENTIAL...WATCH LIKELY FOR SOUTHEASTERN SOUTH DAKOTA...NORTHEASTERN NEBRASKA...AND FAR NORTHWESTERN IOWA
Mesoscale Discussion 1682 NWS Storm Prediction Center Norman OK 0659 PM CDT Fri Aug 09 2019 Areas affected...Southeastern South Dakota...northeastern Nebraska...and far northwestern Iowa Concerning...Severe potential...Watch likely Valid 092359Z - 100200Z Probability of Watch Issuance...80 percent SUMMARY...A downstream WW may be needed across portions of the discussion area by 01Z or so. DISCUSSION...Surface-based storms in south-central South Dakota are continuing to grow upscale while forward-propagating east-southeastward. The presence of locally enhanced low-level shear near a warm front bisecting the region from WNW-ESE will assist in occasional rotation in a few cells along with continued organization of the ongoing complex in the presence of moderate buoyancy. These storms will pose a hail/wind and isolated tornado risk through the evening, and with 290/30 storm motions, these storms should reach the southeastern extent of WW 564 during the 0130-0230Z time frame. Before this time, local extensions of WW 564 or a new WW (likely Severe Thunderstorm) will be coordinated with affected offices. ..Cook/Hart.. 08/09/2019 ...Please see www.spc.noaa.gov for graphic product...

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
500 PM PDT Fri Aug 9 2019

For the eastern North Pacific...east of 140 degrees west longitude:

An area of disturbed weather associated with a broad area of low
pressure is hugging the southern coast of Mexico, and some of the
rainbands are already spreading inland over the state of Oaxaca.
This system remains disorganized, but environmental conditions could
favor some gradual development during the next 2 or 3 days while it
moves west-northwestward just off the southwestern coast of Mexico.
After that time conditions are forecast to become unfavorable for
tropical cyclone formation. Regardless of development, the
disturbance will likely bring locally heavy rainfall along portions
of the southern and southwestern coast of Mexico during the next
couple of days.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 5 days...medium...40 percent.

A tropical wave located about 1000 miles south-southwest of the
Baja California peninsula is producing an area of disorganized
showers and thunderstorms. Environmental conditions are expected to
gradually become more conducive for development through the middle
of next week while the system moves westward or west-northwestward
at 10 to 15 mph.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...medium...40 percent.

MD 1681 CONCERNING TORNADO WATCH 564... FOR MUCH OF SOUTH DAKOTA
Mesoscale Discussion 1681 NWS Storm Prediction Center Norman OK 0553 PM CDT Fri Aug 09 2019 Areas affected...Much of South Dakota Concerning...Tornado Watch 564... Valid 092253Z - 100000Z The severe weather threat for Tornado Watch 564 continues. SUMMARY...The severe threat continues across WW 564. DISCUSSION...A cluster of strong to severe storms continues across central portions of South Dakota near 9V9 and around 40 miles north of VTN. These storms have exhibited occasional rotation along with hail and strong wind gusts, which isn't surprising given the moderate CAPE/strong low-level shear environment in place - especially near the effective warm front. A tornado threat will exist, though radar presentation of ongoing storms hasn't been consistent with classic supercellular/mesocyclonic tornadoes over the last hour or so. In fact, storms appear to be congealing into a small linear segment near Buffalo/Lyman Counties. This evolution is consistent with recent high-resolution guidance/CAMs, which suggest that this cluster will begin to migrate southeastward along the warm front toward southeastern South Dakota over time. Upstream, an isolated, hail and wind-producing cell has exhibited supercellular structure over the past hour or so just northeast through east of Rapid City. This cell will continue to pose a severe risk for the next several hours and will approach western portions of WW 564 during that time. ..Cook.. 08/09/2019 ...Please see www.spc.noaa.gov for graphic product...

Unseasonably warm water and low stream flows due to drought have kept pink salmon out of Prince William Sound, lowering salmon harvests. The year-to-date harvest on Aug. 6 was 13.6 million fish, compared to a recent year-to-date odd-year harvest average of 31.2 million fish. Cordova Times (Alaska), Aug. 9, 2019
