SPC 1200Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1251 AM CDT Sat Aug 30 2025 Valid 301200Z - 311200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... A few strong thunderstorms will be possible across parts of the southern and central Plains today, but any severe potential should remain low. ...DISCUSSION... Flow at mid-levels will remain northwesterly over the top of a moist airmass today in the southern and central Plains. A weak upslope flow regime will be in place to the east of a surface trough over eastern New Mexico and the Texas Panhandle. As surface temperatures warm during the day across this airmass, scattered thunderstorms will develop. Isolated storms may form near the surface trough and instability axis, with increased convective coverage further to the east in the less unstable air. A few strong storms will be possible in areas where convection is co-located with maximized instability. However, lapse rates will be weak suggesting that the severe potential will remain low in the southern and central Plains today. Elsewhere across the continental U.S., no severe threat is expected today and tonight. ..Broyles/Thornton.. 08/30/2025 Read more

SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1148 PM CDT Fri Aug 29 2025 Valid 301200Z - 311200Z ...NO CRITICAL AREAS... ...Synopsis... Fire weather concerns are expected to be low across the CONUS on today. Ridging will continue to build across much of the western US with warming and drying conditions. An upper-level low will be off the coast of the Pacific Northwest, with precipitable water increasing across much of the region west of the Cascades. Conditions west of the Cascades will be much drier, but overall wind speeds are expected to be light with no thunderstorm activity expected. A few spotty Elevated conditions will be possible across portions of northern California across the Coastal Ranges where breezy northerly winds will overlap dry fuels. However, this threat appear to be too brief and localized to include any areas at this time. ..Thornton.. 08/30/2025 ...Please see www.spc.noaa.gov/fire for graphic product... Read more

MD 2023 CONCERNING SEVERE THUNDERSTORM WATCH 604... FOR SOUTHERN HIGH PLAINS
Mesoscale Discussion 2023 NWS Storm Prediction Center Norman OK 0909 PM CDT Fri Aug 29 2025 Areas affected...Southern High Plains Concerning...Severe Thunderstorm Watch 604... Valid 300209Z - 300415Z The severe weather threat for Severe Thunderstorm Watch 604 continues. SUMMARY...Gusty winds may accompany storms as they propagate southeast this evening. DISCUSSION...Several thunderstorm clusters persist this evening across the High Plains from northwest KS into east central NM. This activity appears to be aided by a short-wave trough that is flattening the ridge over CO. 00z soundings from both AMA and DDC exhibited around 7-7.5 C/km lapse rates, and more than adequate shear for maintaining these clusters as they propagate southeast. While large-scale support will continue to encourage some longevity, buoyancy is not particularly strong, especially given the weak low-level inflow. Gusty winds are the main concern with these storms as they move southeast, but a new watch is not currently anticipated downstream. ..Darrow.. 08/30/2025 ...Please see www.spc.noaa.gov for graphic product...

WW 604 SEVERE TSTM CO KS NM OK TX 292100Z - 300400Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 604 NWS Storm Prediction Center Norman OK 400 PM CDT Fri Aug 29 2025 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Southeast Colorado Far Southwest Kansas Northeast New Mexico Western and Central Oklahoma Panhandle Western Texas Panhandle * Effective this Friday afternoon and evening from 400 PM until 1100 PM CDT. * Primary threats include... Scattered large hail events to 1.5 inches in diameter possible Isolated damaging wind gusts to 60 mph possible A tornado or two possible SUMMARY...Ongoing strong to severe thunderstorms across northeast NM and southeast CO are expected to continue through the afternoon and evening, potentially reaching the western TX and OK Panhandles. Additional storms are possible near the southern CO/KS border. The environment supports large hail and isolated damaging gusts. The severe thunderstorm watch area is approximately along and 60 statute miles east and west of a line from 35 miles north northwest of Lamar CO to 15 miles east southeast of Tucumcari NM. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU4). 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 1.5 inches. Extreme turbulence and surface wind gusts to 50 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 29035. ...Mosier Read more

MD 2022 CONCERNING SEVERE THUNDERSTORM WATCH 604... FOR CENTRAL HIGH PLAINS
Mesoscale Discussion 2022 NWS Storm Prediction Center Norman OK 0610 PM CDT Fri Aug 29 2025 Areas affected...Central High Plains Concerning...Severe Thunderstorm Watch 604... Valid 292310Z - 300115Z The severe weather threat for Severe Thunderstorm Watch 604 continues. SUMMARY...Thunderstorm clusters will spread southeast this evening. Isolated severe gusts and marginally severe hail remain possible. DISCUSSION...Multiple thunderstorm clusters have evolved across northeast NM into southwest KS ahead of a short-wave trough. This feature is advancing into western CO/NM and should encourage ongoing activity to spread slowly downstream this evening. However, latest diagnostic data suggests these clusters are rooted within the most buoyant air mass (1500-2000 J/kg MLCAPE) and will gradually advance beyond the primary corridor of instability that extends from eastern NM into western KS. MRMS data suggests the most robust updrafts could be generating hail at times, but the more likely scenario may actually be gusts as lapse rates are not that steep across this region. In the absence of a pronounced LLJ this activity should gradually weaken later this evening. ..Darrow.. 08/29/2025 ...Please see www.spc.noaa.gov for graphic product...

SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0738 PM CDT Fri Aug 29 2025 Valid 300100Z - 301200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE SOUTHERN AND CENTRAL HIGH PLAINS... ...SUMMARY... Thunderstorms with potential for hail and isolated severe gusts will be possible from early to mid evening across parts of the southern and central High Plains. ...Southern and Central High Plains... On water vapor imagery, northwesterly mid-level flow is evident over much of the central U.S. with a ridge over the central High Plains. At the surface, a moist airmass is located across the southern and central Plains, where dewpoints are mostly in the 60s F. An axis of moderate instability is analyzed along the western edge of the moist airmass from far eastern New Mexico north-northeastward into west-central Nebraska. Scattered strong thunderstorms are ongoing near the instability axis, with a few that are severe. The wind profile on the WSR-88D VWP at Dodge City appears to be representative along the instability axis, with 0-6 km shear near 45 knots and strong mid-level speed shear. This will continue to support a marginal severe threat from early to mid evening, mainly with the storms that are close to the instability axis. Hail and isolated severe gusts will be the primary threats. The severe threat will gradually diminish as instability decreases over the next few hours. ..Broyles.. 08/30/2025 Read more
