WW 508 SEVERE TSTM KS NE 061725Z - 070100Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 508 NWS Storm Prediction Center Norman OK 1225 PM CDT Sat Jul 6 2024 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Western and Northern Kansas Central and Southern Nebraska * Effective this Saturday afternoon and evening from 1225 PM until 800 PM CDT. * Primary threats include... Scattered damaging wind gusts to 70 mph likely Scattered large hail and isolated very large hail events to 2.5 inches in diameter possible A tornado or two possible SUMMARY...Clusters of storms will continue to develop and intensify, initially near/north of the Interstate 80 corridor in Nebraska early this afternoon, but also across northwest Kansas. Storms should become more scattered/widespread by late afternoon, especially across south-central Nebraska, where large hail and damaging wind potential may be most focused. The severe thunderstorm watch area is approximately along and 90 statute miles north and south of a line from 65 miles south of Imperial NE to 35 miles east of Grand Island NE. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU8). 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. && 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 550. Mean storm motion vector 29030. ...Guyer Read more

MD 1545 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR THE ADIRONDACKS INTO PARTS OF NORTHERN NEW ENGLAND
Mesoscale Discussion 1545 NWS Storm Prediction Center Norman OK 0452 PM CDT Sat Jul 06 2024 Areas affected...the Adirondacks into Parts of northern New England Concerning...Severe potential...Watch unlikely Valid 062152Z - 062345Z Probability of Watch Issuance...20 percent SUMMARY...Some damaging wind threat is apparent this afternoon across parts of the Adirondacks into northern new England. A watch is not anticipated. DISCUSSION...Thunderstorms, some of which are displaying supercell characteristics on radar, are ongoing this afternoon across parts of the Adirondacks into northern New England. These storms are situated in a fairly healthy mid- and upper-level jet for July, with 50-60 kts of effective bulk shear. Thermodynamically, the environment is fairly moist, with 1.6-1.8" of precipitable water, 1000-1500 J/kg of MLCAPE, and pockets of 7-8 C/km low-level lapse rates. All of this suggests the continued potential for supercells with damaging gusts due to large water loading. Some clustering may occur with time, and this may increase the damaging wind threat with storms. However, a watch is not anticipated at this time due to the expected sparse coverage of damaging gusts. ..Supinie/Hart.. 07/06/2024 ...Please see www.spc.noaa.gov for graphic product...

MD 1547 CONCERNING SEVERE POTENTIAL...WATCH LIKELY FOR SOUTHWEST KANSAS
Mesoscale Discussion 1547 NWS Storm Prediction Center Norman OK 0520 PM CDT Sat Jul 06 2024 Areas affected...southwest Kansas Concerning...Severe potential...Watch likely Valid 062220Z - 062315Z Probability of Watch Issuance...80 percent SUMMARY...Severe thunderstorms will propagate south across western Kansas this evening. New severe thunderstorm watch will likely be issued soon. DISCUSSION...An upward-evolving squall line has developed across western KS just ahead of the primary synoptic front that is surging south across the central high Plains. Northwesterly mid-level flow will increase across western KS this evening and latest model guidance favors a marked increase in the LLJ from the TX Panhandle into southwest KS. This strongly supports a long-lived MCS that should progress across southwest KS with an attendant risk for wind/hail. ..Darrow/Hart.. 07/06/2024 ...Please see www.spc.noaa.gov for graphic product...

Mesoscale Discussion 1546 NWS Storm Prediction Center Norman OK 0500 PM CDT Sat Jul 06 2024 Areas affected...Southeast Nebraska...Southwest Iowa...Northeast Kansas...Northwest Missouri Concerning...Severe potential...Watch likely Valid 062200Z - 062300Z Probability of Watch Issuance...80 percent SUMMARY...New severe thunderstorm watch appears warranted for portions of southeast Nebraska region. DISCUSSION...Organized complex of severe thunderstorms has matured over south-central Nebraska late this afternoon. This MCS is propagating east into a reservoir of strong buoyancy represented by MLCAPE values on the order of 1500 J/kg. LLJ is forecast to increase across northeast KS into southeast NE over the next few hours which should encourage downstream propagation and longevity of the MCS. Large hail and damaging winds are expected and a new severe thunderstorm watch appears warranted. ..Darrow/Hart.. 07/06/2024 ...Please see www.spc.noaa.gov for graphic product...

MD 1544 CONCERNING SEVERE THUNDERSTORM WATCH 508... FOR MUCH OF CENTRAL NEBRASKA INTO NORTHWEST KANSAS
Mesoscale Discussion 1544 NWS Storm Prediction Center Norman OK 0311 PM CDT Sat Jul 06 2024 Areas affected...much of central Nebraska into northwest Kansas Concerning...Severe Thunderstorm Watch 508... Valid 062011Z - 062215Z The severe weather threat for Severe Thunderstorm Watch 508 continues. SUMMARY...Scattered severe storms producing mainly large hail persist over much of south-central Nebraska into northwest Kansas. Areas over eastern Nebraska and northeast Kansas will be monitored for additional watch potential, depending on storm trends. DISCUSSION...A cluster of severe hail storms persists along the warm front over southern Nebraska, with additional activity within the warmer air mass into northwest Kansas. Instability is a bit weaker east of the watch, but a continuation of severe risk is expected later this evening as storms become organized with traveling cold pool. Farther south across western Kansas, visible satellite shows high-based CU along the Colorado/Kansas border, and isolated cells may eventually form here producing localized hail and wind. ..Jewell.. 07/06/2024 ...Please see www.spc.noaa.gov for graphic product...

SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0456 PM CDT Sat Jul 06 2024 Valid 081200Z - 141200Z A large-scale ridge will shift slowly eastward across the Great Basin through much of the extended forecast period. This will promote a continuation of above-average temperatures and low RH across much of the West, where fuels continue to dry. On the western periphery of the ridge, a belt of moderate midlevel southerly flow (with subtle/embedded northward-moving perturbations) will persist across CA into western NV, favoring periods of breezy surface winds in terrain-favored areas each day. While this will likely yield elevated to locally critical conditions across the region (given the hot/dry conditions), confidence in any more than locally critical conditions is too low to add probabilities at this time. However, highlights may eventually be needed as confidence in the exact timing/evolution of the embedded perturbations/stronger midlevel flow increases. Farther north, west-southwesterly midlevel flow will strengthen across the Northwest on Day 5/Wednesday -- between the large-scale ridge and a midlevel trough moving into British Columbia. As a result, surface winds will strengthen amid a hot/dry boundary layer along/east of the Cascades in WA and OR. 40-percent Critical probabilities have been added for these areas, and higher probabilities may eventually be needed as forecast confidence increases. Enhanced midlevel west-southwesterlies will persist across the Northwest through the remainder of the forecast period, with the potential for continued fire-weather concerns. ..Weinman.. 07/06/2024 ...Please see www.spc.noaa.gov/fire for graphic product...
