Area Forecast Discussion National Weather Service Pueblo CO 1239 PM MDT Wed Jul 15 2026 .KEY MESSAGES... - Increased chances of mountain thunderstorms through Friday. - Pockets of heavy rainfall could cause flash flood concerns over recent burn scar areas. - Slightly drier this weekend, with moisture returning to all of SE Colorado next week. && .SHORT TERM /THROUGH THURSDAY/... Issued at 1238 PM MDT Wed Jul 15 2026 Showers and thunderstorms will continue across the mountains through the rest of the day and into early tonight. Main impact concern will be flash flooding over the Willow burn scar, due to pockets of moderate to heavy rainfall. For Thursday, we will continue to see an uptick in available moisture, leading to more widespread coverage for showers and thunderstorms over the mountains. Not too dissimilar from today, showers will fire over the Continental Divide by around midday, increasing in coverage through the afternoon hours. Easterly flow across the region will keep storms tied to the mountains, meaning that the plains will once again remain dry. With PWATs steadily increasing over the region, chances for heavy rainfall will continue to increase as well, meaning that any storm over a burn scar area will be capable of producing flash flooding conditions. Main area of concern will again be the Willow fire. Temperatures will be similar again as well, with 80s to mid-90s. && .LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/... Issued at 1238 PM MDT Wed Jul 15 2026 Uptick in thunderstorm activity will continue on Friday, with PWATs creeping towards the 150% of normal range. Best chances for heavy rain will be over the peak of the Continental Divide, with the main risk area being the Willow burn scar. Storms look to get a little strong as well, with pockets of 800-1000 /kg of CAPE during the afternoon, along with 20-25 knots of bulk shear, which further increases chances for flash flooding. Given the east to northeast steering flow, still expecting the plains to remain dry. Over the weekend, the upper high builds overhead more, pushing the moisture plume a bit further west. As a result, the southeast mountains will remain mostly dry through the weekend, with only scattered POPs over the Continental Divide. Temperatures will also warm a bit, reaching high-90s to low-100s over the far eastern plains by Sunday afternoon. Moving into next week, recycles monsoon moisture is expected to move around the high as it shifts. With PWATs increasing across the state, and a cold front moving onto the plains on Monday, POPs will spread over our entire CWA. Chances for wetting rains over the eastern plains will increase Monday evening towards the middle of next week, with showers and thunderstorms possible each day. Meanwhile, temperatures will drop a few degrees as well, settling right around seasonal averages. Flash flooding over our burn scars will continue to be our main concern. && .AVIATION /18Z TAFS THROUGH 18Z THURSDAY/... Issued at 1109 AM MDT Wed Jul 15 2026 VFR conditions are expected at KALS, KCOS, and KPUB through 24 hours. Winds will gust from the SE this afternoon, 20-25 knots or so at all three terminals. There will be a period where thunderstorms will move over the San Luis Valley, which could impact KALS briefly. Due to scattered coverage, left as PROB30 for now, with chances 22- 03Z this evening. && .PUB WATCHES/WARNINGS/ADVISORIES...

Locally heavy rainfall, lightning, and gusty outflow winds up to 50 mph will be the primary storm risks. Burn scar flash flooding will be possible, particularly for the Willow burn scar along the Continental Divide, if it becomes directly impacted by a stronger storm. Thunderstorms will diminish around midnight. .DAYS TWO THROUGH SEVEN...Thursday through Tuesday Scattered to numerous afternoon and evening thunderstorms will be possible each day through Friday across the mountains and valleys. Locally heavy rainfall capable of producing flash flooding for area burn scars, lightning, and gusty outflow winds up to 50 mph will be the primary storm risks, especially for the Willow burn scar. While daily afternoon and evening thunderstorms return along the Continental Divide through the weekend, warmer and drier air will spread into the southeast mountains plains. Temperatures will approach or exceed the century mark for portions of the plains both days. A pattern change will bring a potential uptick in showers and thunderstorms again to all of southern Colorado early next week, as monsoon moisture increases out west, and a cool front brings increasing low level moisture in easterly upslope flow to the southeast mountains and plains. This will increase the potential for flash flooding on all area burn scars Monday and Tuesday. .SPOTTER INFORMATION STATEMENT... Weather conditions that meet reporting criteria for spotters will be possible over portions of the region. GARBEROGLIO/GARBEROGLIO
