WW 602 SEVERE TSTM CO 242055Z - 250300Z
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...

MD 2009 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR EASTERN COLORADO TO SOUTHWEST KANSAS
Mesoscale Discussion 2009 NWS Storm Prediction Center Norman OK 0246 PM CDT Sun Aug 24 2025 Areas affected...Eastern Colorado to southwest Kansas Concerning...Severe potential...Watch unlikely Valid 241946Z - 242145Z Probability of Watch Issuance...20 percent SUMMARY...An isolated supercell or two appears possible this afternoon across eastern Colorado to southwest Kansas. Large hail, and perhaps a tornado, will be possible. DISCUSSION...Latest GOES imagery show steady vertical development of convective towers near the intersection of a diffuse warm front draped across eastern CO and a decaying outflow boundary from morning convection. Temperatures warming into the upper 70s and low 80s continue to erode lingering MLCIN in the vicinity of the boundary intersection, which should help increase the probability of sustained convection in the coming hours. While it remains unclear how many thunderstorms will emerge from this zone due to weak forcing for ascent, the downstream environment is becoming increasingly favorable for supercells with MLCAPE increasing to around 1500 J/kg and deep-layer wind shear on the order of 35-45 knots in the vicinity of the boundary. Additionally, backed winds on the cool side of the boundary (where temperatures are quickly recovering) may support locally-enhanced low-level SRH and/or augmented low-level vertical vorticity on the boundary itself. Consequently, it is conceivable that a supercell could propagate along the boundary to the southeast with an attendant threat for large hail (possibly as large as 2.5 inches) and perhaps a tornado. Watch issuance is not imminent due to uncertainty regarding storm coverage, but convective trends will continue to be monitored through this corridor. ..Moore/Gleason.. 08/24/2025 ...Please see www.spc.noaa.gov for graphic product...

Tropical Depression Ten-E Forecast Discussion Number 1

1 month 1 week ago
Issued at 200 PM MST Sun Aug 24 2025 995 WTPZ45 KNHC 242033 TCDEP5 Tropical Depression Ten-E Discussion Number 1 NWS National Hurricane Center Miami FL EP102025 200 PM MST Sun Aug 24 2025 Data from both the ASCAT-B and ASCAT-C scatterometers indicate that the broad area of low pressure located well offshore of the southwestern coast of Mexico now has a well-defined circulation. The deep convection has been forming a rudimentary banding structure over the western semicircle of the circulation. Thus, the system is being designated as Tropical Depression Ten-E at this time. The scatterometer observations indicate that the system is just below tropical storm strength, and the intensity estimate is in good agreement with a Dvorak estimate from TAFB. The initial motion estimate is west-northwestward, or 290/12 kt. A mid-level ridge is expected to remain to the northeast of the tropical cyclone during the next few days. This steering pattern should cause a west-northwestward to northwestward track for most of the forecast period. In 4-5 days, the weakening cyclone is expected turn more westward in the low-level flow. The official track forecast lies between the NOAA corrected consensus, HCCA, model and the Google Deep Mind, GDMI, predictions. The cyclone is currently over warm waters within moderate northeasterly vertical wind shear. Although the shear is predicted to lessen over the next couple of days, gradually cooling ocean waters should partially offset the more conducive wind environment. Therefore, only modest strengthening is forecast, and the NHC prediction is roughly in the middle of the model guidance. Around the end of the forecast period, significantly lower SSTs are likely to reduce the system to a remnant low.
