Area Forecast Discussion National Weather Service Pueblo CO 756 AM MDT Thu Jul 10 2025 .KEY MESSAGES... - Showers and thunderstorms will develop over the Mountains and spread east into the I-25 corridor and into the Plains by this evening. - Critical fire weather conditions this afternoon and evening across the Continental Divide and San Luis Valley due to gusty winds and low humidity. - Daily afternoon and evening showers and thunderstorms are expected for the long term period. && .UPDATE... Issued at 754 AM MDT Thu Jul 10 2025 With SPC adding the eastern plains in a hatched area for damaging winds, have updated NDFD to include severe wording with damaging winds possible to the public products. \/Hodanish && .SHORT TERM /THROUGH FRIDAY/... Issued at 326 AM MDT Thu Jul 10 2025 Currently...satellite imagery early this morning shows an upper shortwave over northern Utah, with mid and high level clouds spreading across western Colorado. Temperatures are quite mild across the Plains, with most areas in the mid 70s, and even the San Luis Valley is in the mid 60s. A few more degrees of cooling are expected through sunrise. Today...the upper shortwave over Utah is forecast to track east into southern Wyoming through this afternoon. Upper energy is forecast to push across southern Colorado, sparking showers and thunderstorms by late morning across the Central Mountains. This activity will quickly spread eastward into the Palmer Divide, and south along the I-25 corridor by early afternoon. Moisture will by somewhat limited across the I-25 corridor, with dewpoints only in the upper 40s to near 50 degrees. This will also limit instability, with SBCAPE values near 600-800 j/kg. Shear will be decent, with 0-6 km shear around 30 to 35 kts by afternoon as the shortwave moves into southern Wyoming. Overall, the main threats from thunderstorms will be lightning and gusty outflow winds to near 55 mph over the Palmer Divide and I-25 corridor. As storms track eastward this afternoon, they will encounter slightly better instability, and stronger cells could reach severe limits, with hail near 1 inch in diameter and 60 mph winds. The other main concern for today will be critical fire weather conditions along the Continental Divide and San Luis Valley. Drier air will push eastward by this afternoon on the back side of the upper shortwave. This will bring gusty northwest winds, and relative humidity values in the lower teens. This will lead to critical fire weather conditions this afternoon. This with outdoor burning activity planned should postpone them until another day. Max temperatures today will depend on how quickly convection develops. Temperatures should quickly warm this morning on the Plains, with highs topping out in the mid to upper 90s. Thunderstorm development will likely help keep temperatures along the I-25 corridor from reaching their full potential, with the warmest conditions near the Kansas border. Temperatures across the San Luis Valley will reach into the upper 80s. Tonight...the upper shortwave will continue to push east into central Nebraska overnight. As it does so, a cold front will push south across the Plains by Friday morning. This will help temperatures cool off into the upper 50s to mid 60s across the Plains, with 40s across the San Luis Valley. Moisture will also increase behind the front, with dewpoints returning into the mid 50s across the Plains. Expect shower and thunderstorm activity to move east into Kansas during the evening hours, with dry conditions overnight into Friday morning. Friday...active weather looks to continue on Friday, with another weak disturbance in northwest flow moving across Colorado late in the day. Expect another round of showers and thunderstorms to develop by the afternoon hours, initially over the Central Mountains, then spreading southeast across the Palmer Divide and into the Plains. Temperatures look to be cooler on Friday, with highs in the upper 80s to lower 90s on the Plains. As for thunderstorms, better moisture will lead to better instability, with CAPE values approaching 1000 j/kg. Shear looks a bit weaker though, at around 25 to 30 kts. The main thunderstorm risks will be lightning, wind gusts near 50 mph and nickel size hail, however, a couple of storms could become severe across the Plains. Mozley && .LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/... Issued at 326 AM MDT Thu Jul 10 2025 Friday Night - Wednesday: For the long term period, active is still expected each day, with afternoon and evening showers and thunderstorms for portions of south central and southeastern Colorado. Messy westerly to northerly flow will be in place over the region as a ridge of high pressure sits across the southwest US. While no major forcing is expected, orographic forcing will be in place each day, along with a brief period of heightened forcing from a frontal passage late Friday. These forcing mechanisms, along with moisture in place each day, will allow for scattered showers and thunderstorms to blossom each afternoon and persist into the evening hours. The greatest coverage of showers and storms is expected to remain along the mountains, where forcing will greatest. Like most summer days, a strong thunderstorms or two can't be ruled out, with frequent lightning, gusty outflow winds, small hail, and brief periods of heavy rain the most likely hazards from any stronger storms. Beyond all of that, breezy winds and increased afternoon and evening cloud cover are anticipated through this timeframe. As for temperatures, Saturday is expected to be the coolest day, with below seasonal temperatures anticipated thanks to the aforementioned cold frontal passage late Friday. Then for the rest of the period, near seasonal temperatures return for south central and southeastern Colorado, though there are hints at another possible cold front passage during the end of this period. && .AVIATION /12Z TAFS THROUGH 12Z FRIDAY/... Issued at 326 AM MDT Thu Jul 10 2025 VFR conditions overnight at all three terminals (KALS, KCOS, KPUB). A few showers and thunderstorms will be possible at KALS today with outflow winds being the main concern. Better chances of thunderstorms at KCOS and KPUB this afternoon and evening. Gusty outflow winds along with reduced VIS and CIGS will be possible as storms pass near the terminal. Thunderstorm activity looks to clear the KCOS and KPUB areas by early evening.

The main thunderstorm risks along the I-25 corridor will be wind gusts near 55 mph along with small hail and lightning. As storms progress eastward this afternoon and evening, the environment will become more favorable for stronger storms. A couple could produce wind gusts near 60 mph and hail near 1 inch in diameter. Thunderstorms look to dissipate this evening as they approach the Kansas border. Dangerous fire weather conditions will exist today along the Continental Divide and San Luis Valley, with gusty northwest winds and low humidity values. Avoid activities that could spark a fire. Friday...showers and thunderstorms are forecast to develop over the Central Mountains, and spread southeast into the Palmer Divide and into the Eastern Plains. Lightning, wind gusts near 50 mph and nickel sized hail may be possible with stronger storms. .DAYS TWO THROUGH SEVEN...Friday through Wednesday Daily afternoon and evening showers and thunderstorms are expected Friday through Wednesday. Friday has the highest chances of stronger storms, particularly across the eastern plains, with strong outflow winds around 60 mph the primary hazard. Otherwise, the most likely hazards with any more organized storms will be gusty outflow winds, small hail, frequent lightning, and brief periods of heavy rain. .SPOTTER INFORMATION STATEMENT... Weather conditions that meet reporting criteria for spotters will be possible over portions of the region. 88/SIMCOE
