MD 1683 CONCERNING SEVERE THUNDERSTORM WATCH 516... FOR SOUTHEASTERN NEBRASKA...SOUTHWESTERN IOWA...NORTHEASTERN KANSAS...NORTHWESTERN MISSOURI
Mesoscale Discussion 1683 NWS Storm Prediction Center Norman OK 1045 PM CDT Tue Jul 15 2025 Areas affected...southeastern Nebraska...southwestern Iowa...northeastern Kansas...northwestern Missouri Concerning...Severe Thunderstorm Watch 516... Valid 160345Z - 160545Z The severe weather threat for Severe Thunderstorm Watch 516 continues. SUMMARY...The ongoing cluster of storms has been generally weakening, but continues to promote strong surface gusts, which could still sporadically approach or exceed severe limits. This will continue to spread southeastward through Midnight-2 AM CDT, particularly across the southeast Nebraska vicinity. It is not clear that a new severe weather watch will be needed downstream, but trends will continue to be monitored. DISCUSSION...Notable surface pressure rises (2-4+ mb 2-hourly) have been maintained within the cold pool on the southwestern flank of the forward propagating convective system, supporting the southeastward and southward advancement of the cold pool across the Norfolk, Columbus, Grand Island, Hastings, Kearney and Lexington vicinities of Nebraska. The more intense leading edge of the convection has become a bit more displaced above/to the cool side of the gust front, and now appears generally focused within forcing associated with warm advection, on the nose a strengthening southerly low-level jet associated with nocturnal boundary-layer decoupling. However, with increasing inhibition associated with the boundary-layer cooling, coupled with warmer mid-level temperatures with southeastward extent across the Missouri Valley and central Great Plains, it remains unclear how much longer near surface updraft inflow will be sufficient to maintain vigorous thunderstorm development. Based on the latest objective analysis, a corridor of better low-level moisture flanking the Missouri River vicinity might promote the best potential for lingering stronger thunderstorm development into 05-07Z time frame, which may be accompanied by a continuing potential to produce strong to severe surface gusts. ..Kerr.. 07/16/2025 ...Please see www.spc.noaa.gov for graphic product...

WW 515 SEVERE TSTM WY 152230Z - 160400Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 515 NWS Storm Prediction Center Norman OK 430 PM MDT Tue Jul 15 2025 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Central Wyoming * Effective this Tuesday afternoon and evening from 430 PM until 1000 PM MDT. * Primary threats include... Scattered damaging wind gusts to 70 mph possible Isolated large hail events to 1 inch in diameter possible SUMMARY...A band of thunderstorms will likely intensify while moving eastward across central Wyoming, with the potential to produce severe outflow gusts up to 70 mph and isolated large hail up to 1 inch in diameter. The severe thunderstorm watch area is approximately along and 60 statute miles north and south of a line from 40 miles northwest of Riverton WY to 45 miles north northeast of Casper WY. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU5). 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 513...WW 514... AVIATION...A few severe thunderstorms with hail surface and aloft to 1 inch.

MD 1682 CONCERNING SEVERE THUNDERSTORM WATCH 514... FOR PARTS OF SOUTHWESTERN MINNESOTA...SOUTHEASTERN SOUTH DAKOTA...NORTHWESTERN IOWA...SOUTHERN AND EASTERN NEBRASKA
Mesoscale Discussion 1682 NWS Storm Prediction Center Norman OK 0819 PM CDT Tue Jul 15 2025 Areas affected...parts of southwestern Minnesota...southeastern South Dakota...northwestern Iowa...southern and eastern Nebraska Concerning...Severe Thunderstorm Watch 514... Valid 160119Z - 160245Z The severe weather threat for Severe Thunderstorm Watch 514 continues. SUMMARY...An organized convective system probably will maintain intensity with a continuing risk for strong to severe gusts as it propagates southeastward through 9-11 PM CDT. DISCUSSION...Convection has grown upscale into an organizing convective system, including the evolution of a couple of notable embedded meso-beta scale cyclonic circulations. One associated southeastward cold pool surge is ongoing across/southeast of the Yankton SD vicinity, at a forward propagation around 30 kt. To the southwest, another southeastward surge across and southeast of Broken Bow NE is a bit slower, around 20 kt, but the nose of a nocturnally strengthening low-level jet (in excess of 30 around 850 mb) may begin interacting with this portion of the QLCS by 03-04Z. Inflow of seasonably moist boundary-layer air characterized by sizable CAPE appears likely to be maintained through this time frame, and perhaps a bit beyond. ..Kerr.. 07/16/2025 ...Please see www.spc.noaa.gov for graphic product...

MD 1680 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR SOUTHEASTERN ARIZONA
Mesoscale Discussion 1680 NWS Storm Prediction Center Norman OK 0739 PM CDT Tue Jul 15 2025 Areas affected...southeastern Arizona Concerning...Severe potential...Watch unlikely Valid 160039Z - 160245Z Probability of Watch Issuance...5 percent SUMMARY...Marginal risk for strong to severe wind will continue through the afternoon. DISCUSSION...Thunderstorm activity continues across portions of southeastern Arizona, with occasional intense cores noted. Temperatures have warmed to the upper 90s to 100 F through the afternoon/evening with dew point spreads of around 40-45 degrees. The large dew point spread and low level lapse rates around 8-9 C/km will promote a few instances of severe wind. This threat looks to remain too localized for watch issuance. ..Thornton.. 07/16/2025 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...TWC...
