SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1218 AM CDT Sat Jul 12 2025 Valid 131200Z - 141200Z ...Synopsis... A mid-level shortwave will move across the periphery of the western ridge on Sunday. This will bring an increase in westerly winds across the Cascades in central Washington and Oregon. Winds will largely remain Elevated (at around 10-15 mph) but some locally Critical conditions will be possible in the Cascade gaps. Fuels in this region are critically dry, with ERCs exceeding the 90th percentile for dryness. ..Thornton.. 07/12/2025 ...Please see www.spc.noaa.gov/fire for graphic product... Read more

WW 509 SEVERE TSTM CO KS NE WY 112220Z - 120500Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 509 NWS Storm Prediction Center Norman OK 420 PM MDT Fri Jul 11 2025 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of North-Central and Northeast Colorado Far Northwest Kansas Southwest Nebraska and the Nebraska Panhandle Southeast Wyoming * Effective this Friday afternoon and evening from 420 PM until 1100 PM MDT. * Primary threats include... Scattered damaging winds and isolated significant gusts to 75 mph possible Scattered large hail and isolated very large hail events to 2 inches in diameter possible SUMMARY...Scattered strong to severe thunderstorms should spread generally east-southeastward this evening while posing a threat for both large hail and severe/damaging winds. The largest hail may reach up to 1-2 inches in diameter, while peak gusts of 65-75 mph appear possible if a cluster of thunderstorms can form later this evening. The severe thunderstorm watch area is approximately along and 60 statute miles north and south of a line from 30 miles west southwest of Cheyenne WY to 15 miles northeast of Mccook NE. 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. && OTHER WATCH INFORMATION...CONTINUE...WW 505...WW 506...WW 507...WW 508... AVIATION...A few severe thunderstorms with hail surface and aloft to 2 inches. Extreme turbulence and surface wind gusts to 65 knots. A few cumulonimbi with maximum tops to 500.

MD 1651 CONCERNING SEVERE THUNDERSTORM WATCH 510... FOR EASTERN NEW MEXICO INTO THE TEXAS/OKLAHOMA PANHANDLES
Mesoscale Discussion 1651 NWS Storm Prediction Center Norman OK 0922 PM CDT Fri Jul 11 2025 Areas affected...eastern New Mexico into the Texas/Oklahoma Panhandles Concerning...Severe Thunderstorm Watch 510... Valid 120222Z - 120345Z The severe weather threat for Severe Thunderstorm Watch 510 continues. SUMMARY...Damaging wind threat is increasing within WW510. DISCUSSION...Thunderstorms in eastern New Mexico have shown better organization along outflow over the last 20-30 minutes. In addition, cloud top cooling is noted on infrared satellite indicating some uptick in intensity. As this line advances into the Texas Panhandle, the damaging wind risk may increase over the next couple of hours. The downstream environment remains favorable unstable. The 00z RAOB from AMA shows steep low level lapse rates and ample MLCAPE. While diurnal heating has ended and MLCIN is increasing, this line segment will likely be able to maintain intensity for the next couple of hours as it tracks southeastward aided by modest south easterlies around 20-25 kts noted from KAMA. In addition, new development has occurred ahead of the main line of storms which may pose a risk for severe hail. Local expansion of WW510 may be needed into the OK/TX Panhandles. ..Thornton.. 07/12/2025 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...DDC...AMA...PUB...ABQ...

MD 1650 CONCERNING SEVERE THUNDERSTORM WATCH 509... FOR SOUTHEASTERN WYOMING...NORTHEASTERN COLORADO...WESTERN NEBRASKA
Mesoscale Discussion 1650 NWS Storm Prediction Center Norman OK 0832 PM CDT Fri Jul 11 2025 Areas affected...southeastern Wyoming...northeastern Colorado...western Nebraska Concerning...Severe Thunderstorm Watch 509... Valid 120132Z - 120300Z The severe weather threat for Severe Thunderstorm Watch 509 continues. SUMMARY...Threat for large hail and damaging wind continues in WW509. DISCUSSION...Outflow interactions from storms moving off of the high terrain has led to a steady increase in thunderstorm activity across northeastern Colorado into western Nebraska. Initial supercells have been efficient at producing 1-1.5 (occasionally 2") hail. As storms further congeal along outflow, the damaging wind risk may increase through the evening across eastern Colorado into northwest Kansas. Mode remains somewhat disorganized for now, with much of the activity north of the front. For now, more discrete convection will continue to pose a risk for large hail. ..Thornton.. 07/12/2025 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...LBF...GLD...BOU...CYS...
