WW 569 SEVERE TSTM KS 032140Z - 040500Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 569 NWS Storm Prediction Center Norman OK 440 PM CDT Sun Aug 3 2025 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Western Kansas * Effective this Sunday afternoon from 440 PM until Midnight CDT. * Primary threats include... Scattered large hail and isolated very large hail events to 3 inches in diameter possible Isolated damaging wind gusts to 70 mph possible SUMMARY...Ongoing supercells should continue to track southward late this afternoon and evening across parts of western Kansas. Scattered large to isolated very large hail will be possible with these supercells given a rather favorable environment. Peak hailstone diameters may reach up to 2-3 inches in diameter on an isolated basis. Occasional severe/damaging winds may also occur. The severe thunderstorm watch area is approximately along and 60 statute miles east and west of a line from 55 miles north of Garden City KS to 60 miles south of Garden City KS. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU9). 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 3 inches. Extreme turbulence and surface wind gusts to 60 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 36020. ...Gleason Read more

MD 1881 CONCERNING SEVERE THUNDERSTORM WATCH 569... FOR PARTS OF SOUTHWEST KS...FAR SOUTHEAST CO...THE OK PANHANDLE...NORTHERN TX PANHANDLE...AND NORTHWEST OK
Mesoscale Discussion 1881 NWS Storm Prediction Center Norman OK 0621 PM CDT Sun Aug 03 2025 Areas affected...Parts of southwest KS...far southeast CO...the OK Panhandle...northern TX Panhandle...and northwest OK Concerning...Severe Thunderstorm Watch 569... Valid 032321Z - 040045Z The severe weather threat for Severe Thunderstorm Watch 569 continues. SUMMARY...The severe risk, including the potential for very large hail and severe wind gusts, will continue spreading southward across southwest KS in Severe Thunderstorm Watch 569. A downstream watch should eventually be needed. DISCUSSION...The latest radar data from GLD/DDC depicts a complex convective evolution across southwest KS this evening. Along the western KS/eastern CO border, a long-lived discrete supercell is tracking southward, which will continue to pose a risk of very large hail, severe wind gusts, and brief tornadoes (given a strong/established mesocyclone and unstable boundary layer). To its east, an earlier long-lived supercell is evolving into a large cluster of storms, with chaotic storm splits and new updrafts developing along outflow. A long/straight hodograph (around 50 kt of effective shear) and moderate surface-based buoyancy should continue to promote storm splits and embedded cells capable of producing very large hail and severe gusts. However, the recent signs of upscale growth into a large cluster may tend to favor an increasing risk of severe wind gusts with time/southward extent. In general, this activity will continue spreading southward across southwest KS (in Severe Thunderstorm Watch 569), and eventually into the OK/TX Panhandles and possibly northwest OK. While lingering inhibition associated with previous convective overturning does cast some uncertainty on the severe risk with southward extent, the established storms and favorable deep-layer shear should support a continued risk. Therefore, a downstream watch should eventually be needed. ..Weinman/Gleason.. 08/03/2025 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...OUN...DDC...GLD...AMA...PUB...

MD 1880 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR PARTS OF WESTERN/CENTRAL NE...FAR SOUTH-CENTRAL SD...AND FAR NORTHEAST CO
Mesoscale Discussion 1880 NWS Storm Prediction Center Norman OK 0444 PM CDT Sun Aug 03 2025 Areas affected...Parts of western/central NE...far south-central SD...and far northeast CO Concerning...Severe potential...Watch unlikely Valid 032144Z - 032345Z Probability of Watch Issuance...20 percent SUMMARY...Sporadic severe wind gusts and isolated large hail will be possible for the next several hours. A watch issuance is not currently expected, though convective trends are being monitored. DISCUSSION...A cluster of thunderstorms has developed along/immediately ahead of a weak surface boundary/wind shift in western/central NE, with additional cells developing farther north along the boundary into far south-central SD. Diurnal heating/destabilization of a moist boundary layer (around middle 60s dewpoints) and steep midlevel lapse rates have contributed to moderate surface-based instability. Given the mesoscale focus for storms and favorable buoyancy, sporadic severe wind gusts and isolated large hail will be possible with storms evolving along/south of the boundary. However, with weak large-scale forcing for ascent and only modest deep-layer flow/shear (around 25 kt of 0-6 km shear per LNX VWP), the overall severe threat should remain fairly disorganized/sporadic. Therefore, a watch issuance is not currently expected, though convective trends are being monitored. ..Weinman/Gleason.. 08/03/2025 ...Please see www.spc.noaa.gov for graphic product...

MD 1879 CONCERNING SEVERE POTENTIAL...WATCH POSSIBLE FOR WESTERN KS
Mesoscale Discussion 1879 NWS Storm Prediction Center Norman OK 0349 PM CDT Sun Aug 03 2025 Areas affected...western KS Concerning...Severe potential...Watch possible Valid 032049Z - 032245Z Probability of Watch Issuance...40 percent SUMMARY...Isolated strong to severe thunderstorms will track south/southeast across western Kansas through early evening. Large hail and strong gusts are possible with the strongest storms. DISCUSSION...Isolated thunderstorms have developed this afternoon along the strong moisture gradient across northwest KS. Steep midlevel lapse rates near 8 C/km are aiding in moderate to strong destabilization with MLCAPE values near 2000-2500 J/kg. While vertical shear is somewhat modest across northwest KS, these storms will encounter stronger effective shear magnitudes greater than 30 kt as they track south. These storms will also move into the more moist boundary layer. As a result, additional convection or intensification is possible with time and southward extent. The favorable thermodynamic and kinematic environment will support isolated large hail. Additionally, some guidance suggests clustering could occur toward evening. If this scenario occurs, damaging wind potential could increase as well. Trends will be monitored for possible watch issuance. ..Leitman/Smith.. 08/03/2025 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...OUN...DDC...GLD...AMA...

MD 1878 CONCERNING SEVERE POTENTIAL...WATCH POSSIBLE FOR PORTIONS OF NORTHEAST NM INTO THE OK/TX PANHANDLES
Mesoscale Discussion 1878 NWS Storm Prediction Center Norman OK 0336 PM CDT Sun Aug 03 2025 Areas affected...portions of northeast NM into the OK/TX Panhandles Concerning...Severe potential...Watch possible Valid 032036Z - 032230Z Probability of Watch Issuance...40 percent SUMMARY...Isolated thunderstorms will develop southeast from northeast New Mexico into the Oklahoma and Texas Panhandles the next few hours. A few instances of large hail and strong/severe gusts are possible. DISCUSSION...Isolated thunderstorms are developing this afternoon within low-level convergence/upslope. Strong heating has allowed temperatures to climb into the low to mid 80s F behind morning convection and outflow. South/southeasterly low-level winds have maintained mid-60s F dewpoints beneath steep midlevel lapse rates. This is fostering moderate destabilization, with 1000-2000 J/kg MLCAPE noted in 20z mesoanalysis. Vertically veering winds profiles, with increasing northwesterly flow aloft is contributing to fairly robust shear, with effective shear magnitudes greater than 40 kts apparent in regional VWP and mesoanalysis data. This environment will support organized cells capable of producing large hail and strong/severe gusts. Convective coverage remains uncertain, but could increase with southward extent toward evening. This area is being monitored for possible severe thunderstorm watch issuance. ..Leitman/Smith.. 08/03/2025 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...LUB...AMA...ABQ...

MD 1877 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR SOUTHWESTERN INTO PARTS OF EASTERN OREGON
Mesoscale Discussion 1877 NWS Storm Prediction Center Norman OK 0244 PM CDT Sun Aug 03 2025 Areas affected...Southwestern into parts of eastern Oregon Concerning...Severe potential...Watch unlikely Valid 031944Z - 032145Z Probability of Watch Issuance...20 percent SUMMARY...Scattered afternoon thunderstorms will be capable of strong to severe wind gusts and mainly small hail. A watch is not expected this afternoon. DISCUSSION...Cumulus towers continue to deepen along and east of the Cascades in southwest Oregon. This is in response to an approaching shortwave trough. While these thunderstorms have been slow to move off of the terrain thus far, continued heating in southern/eastern Oregon will likely erode remaining MLCIN within the next 1-2 hours. Additional storm development is likely through the afternoon as well. With elevated convection associated with a small-scale perturbation moving through northeast Oregon, development within the Blue Mountains is less certain. However, additional heating during the afternoon may still be sufficient for this to occur. Steep low and mid-level lapse rates and 20-25 kts of shear (which will marginally improve to near 30 kts with time) will result in marginally organized storms capable of severe wind gusts. Thermodynamic profiles will be conducive to mainly small hail, but isolated hail near 1 inch could occur in the most intense storms. ..Wendt/Smith.. 08/03/2025 ...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 0340 PM CDT Sun Aug 03 2025 Valid 051200Z - 111200Z A persistent mid/upper-level trough is forecast to remain across the Northwest U.S. Day 3/Tuesday into Day 7/Saturday. Meanwhile, a mid/upper-level ridge centered over the Desert Southwest Day 3/Sunday is forecast to slowly build northwestward into the southern Great Basin through at least Day 6/Friday while remaining quasistationary over the Desert Southwest. ...Great Basin/Southwest/Rocky Mountains: Day 3/Tuesday - Day 6/Friday... Multiple days of hot, dry and windy conditions are expected across the Great Basin, northern Arizona, and western portions of the Rocky Mountains Day 3/Tuesday through Day 6/Friday. At this time, critical fire weather conditions appear most likely across portions of central/southern Utah, far northern Arizona, and far eastern Nevada Day 3/Tuesday and Day 4/Wednesday as mid/upper-level winds increase over the area sandwiched between the base of the trough and along the northern periphery of the ridge. Fuels across this region remain extremely receptive to fire spread owing to lack of recent appreciable rainfall and subsequent ongoing moderate/severe drought conditions. Thereafter, guidance begins to diverge a bit regarding the evolution of the upper-level trough/ridge pattern. Nevertheless, persistent enhanced deep-layer flow atop receptive fuels coupled with dry to very dry low-levels suggest continued chances for near Critical conditions Day 5/Thursday and Day 6/Friday. Enhanced fire weather conditions are forecast to finally diminish Day 7/Saturday as the trough/ridge shift away from the area. ...Dry Thunderstorms... Thunderstorms are possible across portions of Arizona into far southern Utah beginning Day 4/Wednesday through much of the work week. Dry thunderstorms are possible across northern Arizona and southern Utah, where fuels remain receptive to fire spread due to the ongoing severe/extreme drought conditions. However, increasing PWATs and uncertainties regarding coverage/location of any thunderstorms precludes introducing probabilities for dry thunderstorms at this time. ..Elliott.. 08/03/2025 ...Please see www.spc.noaa.gov/fire for graphic product...
