Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0800 PM CDT Sun Aug 24 2025 Valid 250100Z - 251200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM SOUTHEAST COLORADO TO THE TX/OK PANHANDLE AND WESTERN OKLAHOMA... ...SUMMARY... A few severe thunderstorms are expected to continue evening across the southern/central High Plains spanning from eastern Colorado into western Oklahoma. Scattered strong to severe thunderstorms are also possible for a few more hours across portions of Pennsylvania and New York. ...Discussion... Several thunderstorms are ongoing across southeast Colorado where a few hail and wind reports have been received. These storms are expected to congeal into larger clusters. However, the severe threat should only last for a few more hours while moderate instability remains. However, decreasing instability and increasing inhibition should limit the overall threat by later this evening. See MCD 2012 for additional discussion of this threat area. A few severe storms have developed across western Oklahoma this evening where 1000 to 1500 J/kg MLCAPE and moderate shear is present. These storms should persist for at least a few more hours with a threat for large hail and severe wind gusts. Increasing inhibition should reduce the threat by later this evening. See MCD 2011 for additional discussion of the near-term threat across this area. ..Bentley.. 08/25/2025 Read more

MD 2010 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR PORTIONS OF THE OKLAHOMA AND TEXAS PANHANDLES INTO NORTHWEST OKLAHOMA AND FAR SOUTHWEST KANSAS
Mesoscale Discussion 2010 NWS Storm Prediction Center Norman OK 0357 PM CDT Sun Aug 24 2025 Areas affected...Portions of the Oklahoma and Texas Panhandles into northwest Oklahoma and far southwest Kansas Concerning...Severe potential...Watch unlikely Valid 242057Z - 242300Z Probability of Watch Issuance...20 percent SUMMARY...Thunderstorm development across parts of the OK/TX Panhandles into far northwest Oklahoma and far southwest Kansas appears possible this afternoon. If initiation occurs, severe hail/wind will be possible. DISCUSSION...Recent GOES imagery and surface observations show slow vertical development of cumulus along an outflow boundary draped from northwest OK into southwest KS/eastern CO. Temperatures warming into the low 90s and low/mid 80s on the warm and cool side of the boundary (respectively) suggest that MLCIN continues to erode across this region. Given that forcing for ascent is weak and largely tied to the outflow boundary, it remains uncertain whether or not sustained convective initiation will occur through peak heating. However, the recent satellite and surface observation trends suggest that this is a possibility. If sustained convection can develop, it will mature within an environment characterized by around 1000-1500 J/kg MLCAPE and elongated hodographs featuring around 30-40 knots of effective bulk shear per recent forecast soundings. Convective coverage would likely be sufficiently isolated to promote supercells, which may be capable of severe gusts and large hail (possibly up to 2-2.5 inches). Enhanced near-surface vorticity along the boundary and southeasterly flow/augmented low-level SRH to the immediate east of the boundary may support some tornado threat. While watch issuance is not expected due to uncertainty regarding initiation, convective trends will be monitored. ..Moore/Gleason.. 08/24/2025 ...Please see www.spc.noaa.gov for graphic product...

URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 602 NWS Storm Prediction Center Norman OK 255 PM MDT Sun Aug 24 2025 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Eastern Colorado * Effective this Sunday afternoon and evening from 255 PM until 900 PM MDT. * Primary threats include... Scattered large hail and isolated very large hail events to 2 inches in diameter possible Isolated damaging wind gusts to 70 mph possible SUMMARY...Multiple supercells should continue to pose a threat for mainly large hail up to 1-2 inches in diameter as they move slowly south-southeastward across parts of eastern Colorado this afternoon and evening. Occasional severe/damaging winds may also occur. The severe thunderstorm watch area is approximately along and 50 statute miles north and south of a line from 20 miles west northwest of Pueblo CO to 35 miles south southeast of Burlington CO. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU2). 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 inches. Extreme turbulence and surface wind gusts to 60 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 35020. ...Gleason Read more

SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0433 PM CDT Sun Aug 24 2025 Valid 261200Z - 011200Z Upper-level troughing is likely to continue over much of the West this week but weaken from its peak this weekend. Weak upper-level troughing is forecast to develop off the West Coast through mid-week with an upper-level trough likely to approach the Northwest Day 5/Thursday. Monsoonal moisture will continue to push northward through the Northwest and the Northern Rockies by Day 5/Thursday. Daily wet thunderstorms and showers remain likely for much of the southern/central Intermountain West, with wet thunderstorms and wetting rain moving into central/north Idaho and western Montana Day 4/Wednesday - Day 5/Thursday. Drier air will begin to filter into the West behind this monsoonal surge, mostly from west to east mid to late week. Mixed wet/dry thunderstorms over receptive fuels are possible in portions of the Cascades, especially from northern Oregon northward, and northern Rockies mainly north Idaho and northwest Montana. Additionally, as drier air filters into portions of California and the Great Basin, areas will be monitored for potential introduction of dry thunderstorm probabilities. The main reason for not including probabilities at this time is the uncertainty regarding the spatial extent and magnitude of ongoing/upcoming wetting rain coupled with thunderstorm chances away from these areas. ..Nauslar.. 08/24/2025 ...Please see www.spc.noaa.gov/fire for graphic product...
