NWS Pueblo, CO wrote its last area forecast discussion before the first event at Jun 16, 2:11 PM MST, 1 hour 2 minutes earlier.
Area Forecast Discussion National Weather Service Pueblo CO 311 PM MDT Wed Jun 16 2021 .SHORT TERM...(This evening through Thursday) Issued at 240 PM MDT Wed Jun 16 2021 Currently...satellite imagery shows high pressure sitting over the Four Corners region early this afternoon, with energy dropping south across Central Colorado. Radar shows scattered showers and thunderstorms, mainly over the higher terrain, east into the Palmer Divide and I-25 corridor. Temperatures are hot, with upper 90s to lower 100s across the region. Winds are generally light out of the southeast. Rest of today...models in good agreement with continued showers and thunderstorms over the higher terrain, dropping south-southeast. The lower levels have dried out considerably, with elevated LCL heights. The main concern for today will be the potential for gusty outflow winds. DCAPE values are approaching 2000 j/kg, and when combined with the high LCL heights (stout inverted V sounding profiles), will lead to the enhanced wind threat. Expect coverage to continue to spread east into the I-25 corridor this afternoon, especially across the Palmer Divide region. Stronger storms are also occurring over the southern Sangre de Cristo Range, into the Raton Mesa region. Over the Mountains, dry air will likely limit precipitation reaching the ground, leading to an elevated dry thunderstorm risk. This will continue to be monitored. Tonight...not anticipating much change to the upper pattern with high pressure sitting over the Four Corners region. The upper disturbance responsible for this afternoon's convection will continue to shift south and clear into New Mexico by midnight. As for the current thunderstorms, expect activity to dissipate this evening and the upper energy shifts southward, and loss of daytime heating. Skies will clear late tonight into Thursday morning. Overnight lows will be mild with 60s across the region. Thursday...again, the upper level high is forecast to sit across the Four Corners region throughout the day. The main difference from today, will be a lack of upper level disturbance rotating south across Colorado. Residual moisture will likely lead to isolated to scattered afternoon thunderstorms, mainly over the Mountains. This activity will shift southward given the weak northerly steering flows aloft. Dry air will continue to sit over the lower levels, with dry lightning a concern over the Mountains. In addition, high LCL heights and high DCAPE values will lead to another round of gusty outflow winds. Temperatures will once again be hot, with upper 90s to lower 100s across the lower elevations. Mozley .LONG TERM...(Thursday night through Wednesday) Issued at 240 PM MDT Wed Jun 16 2021 For Friday into Saturday, the forecast area is expected to remain along the southern periphery of a zone of westerly to northwesterly flow aloft -- between a midlevel anticyclone over the Desert Southwest and midlevel troughing over Canada. On Friday, a low- amplitude impulse advancing through the flow is expected the graze the region, with its corresponding low-level mass response favoring the southward progression of a weak cold front over the plains. Recycled, post-frontal moisture resulting in weak to moderate buoyancy, and upslope flow, will be in place from the plains to the eastern slopes of the southeastern mountains -- such that orographically-enhanced convection forming over the central/south- central Colorado mountains vicinity should progress eastward each day. As strong cold pools congeal amid deep inverted-V thermodynamic profiles, small forward-propagating convective clusters may affect areas from the Interstate-25 corridor eastward across the portions of the southeast plains. Some of the storms could be strong, and a few isolated severe storms cannot be ruled out. Present indications are that the greatest coverage of this activity, and most intense storms, should be on Saturday when deep shear is modestly enhanced, in association with a lower-latitude midlevel speed maximum advancing southeastward from the central Great Basin. Also, burn- scar flash flooding could be a concern on Friday and Saturday over the southeast mountains vicinity, as storms initially form and potentially move over the same locations. For Sunday into early next week, amplification of a large-scale trough extending southward over the CONUS from Canada will be accompanied by a secondary and stronger southward surge of a continental air mass later Sunday into Sunday night and Monday morning. Upslope flow behind the leading edge of this air mass may phase with adequate lingering moisture for a broad area of rain and perhaps embedded thunderstorms to affect the southeast mountains and the plains for Sunday night, with comparatively drier conditions over the San Luis Valley and vicinity. Drier and notably cooler air is expected to subsequently prevail through the middle of next week. With high temperatures currently expected to be in the 70s and 80s on Monday over the plains and valleys, and the 50s and 60s over the mountains. Monday temperatures may be even cooler over the plains vicinity, if widespread clouds/precipitation amid the cold-advection regime were to occur. && .AVIATION...(For the 00Z TAFS through 00Z Thursday evening) Issued at 240 PM MDT Wed Jun 16 2021 KALS...VFR conditions for the next 24 hours with a few passing mid and high clouds. Expect thunderstorms over the San Luis Valley, but they do not look to impact the terminal. Winds will generally be light at less than 12 kts. KCOS and KPUB...a few thunderstorms are possible this afternoon and evening. Lightning, gusty outflow winds and briefly reduced CIGS and VIS are all possible with any cells that move across the terminal. VFR conditions are expected overnight into Thursday once thunderstorms dissipate. Winds will generally be light at less than 12 kts through the next 24 hours.

The main threats from these storms will be lightning and wind gusts to 50 mph. For Friday through Sunday, afternoon and evening thunderstorms will become more numerous with thunderstorms possible on the plains. .SPOTTER INFORMATION STATEMENT... Weather conditions that meet criteria for spotters may be possible over the Mountains, into the Interstate 25 corridor this afternoon and evening. 88/88
