Day 4-8 Outlook
Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0326 AM CDT Sun Jul 14 2024 Valid 171200Z - 221200Z ...DISCUSSION... Expansive upper ridging is expected to be in place across much of western North America on D4/Wednesday, with this ridging expected to persist through the weekend. Upper troughing will likely extend from northern Quebec through Ontario, the Upper Great Lakes, and the Mid MS Valley early D4/Wednesday. Primary portion of this upper trough is forecast to gradually shift eastward across the remainder of Ontario and the Upper Great Lakes on D4/Wednesday and the Northeast on D5/Thursday, but modest upper troughing is expected to remain in place over much of the eastern CONUS into the weekend. At the same time, a cold front will gradually push southward/southeastward across the central Plains, OH Valley, and Northeast on D4/Wednesday and northern part of the southern Plains, Mid-South, and TN Valley on D5/Thursday. Some limited severe potential may exist across the Northeast on D4/Wednesday before the front clears the region. After D4/Wednesday, progression of the front will displace the better low-level moisture south of the stronger flow aloft, limiting the severe-storm potential across much of the central and eastern CONUS through the weekend. The only exception is across the High Plains, where modest low-level moisture beneath vertically veering wind profiles could support a few strong to severe storms each afternoon. Read more

MD 1609 CONCERNING SEVERE THUNDERSTORM WATCH 527...529... FOR CENTRAL AND EASTERN SOUTH DAKOTA...SOUTHWEST MINNESOTA
Mesoscale Discussion 1609 NWS Storm Prediction Center Norman OK 0129 AM CDT Sun Jul 14 2024 Areas affected...Central and Eastern South Dakota...Southwest Minnesota Concerning...Severe Thunderstorm Watch 527...529... Valid 140629Z - 140830Z The severe weather threat for Severe Thunderstorm Watch 527, 529 continues. SUMMARY...A wind-damage and large-hail threat will likely continue across parts of central and eastern South Dakota over the next few hours, and could affect southwest Minnesota later tonight. Gusts over 80 mph will be possible ahead of the ongoing bow. Weather watch issuance will need to be considered for parts of eastern South Dakota. DISCUSSION...The latest mosaic radar imagery shows a well-developed bow echo just to the west and northwest of Pierre, South Dakota. The bow is moving east-southeastward along a corridor of moderate instability, where the RAP is analyzing MLCAPE in the 1200 to 2000 J/kg range. The line appears to be supported by a 45 to 55 knot mid-level speed max over northwestern South Dakota. As the line continues to move east-southeastward at around 50 knots, severe gusts will be likely along the leading edge of the bow. Wind gusts above 80 mph will be possible near the apex of the bow. As the line moves further east, it will encounter stronger instability across southeastern South Dakota. This could help to maintain intensity with the line, making weather watch issuance likely across parts of eastern South Dakota and southwest Minnesota. ..Broyles.. 07/14/2024 ...Please see www.spc.noaa.gov for graphic product...

WW 530 SEVERE TSTM MN WI 140625Z - 141100Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 530 NWS Storm Prediction Center Norman OK 125 AM CDT Sun Jul 14 2024 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Southeastern Minnesota West-central and southwestern Wisconsin * Effective this Sunday morning from 125 AM until 600 AM CDT. * Primary threats include... Scattered damaging wind gusts to 70 mph possible Isolated very large hail events to 2 inches in diameter possible SUMMARY...The best-organized part of a thunderstorm complex has been producing large hail and measured severe gusts in and near the Twin Cities over the past 1-2 hours, and may maintain severe potential southeastward through the watch area before weakening. Isolated severe hail also is possible from somewhat less-organized convection to its east and southeast. The severe thunderstorm watch area is approximately along and 40 statute miles north and south of a line from 5 miles west southwest of Rochester MN to 50 miles east northeast of La Crosse WI. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU0). 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 527...WW 528...WW 529... AVIATION...A few severe thunderstorms with hail surface and aloft to 2 inches. Extreme turbulence and surface wind gusts to 60 knots. A few cumulonimbi with maximum tops to 550. Mean storm motion vector 31040. ...Edwards Read more
