Area forecast discussion, Jul 17, 3:23 PM MDT, 13 minutes before
Area Forecast Discussion National Weather Service Pueblo CO 323 PM MDT Tue Jul 17 2018 .SHORT TERM...(This evening through Wednesday) Issued at 241 PM MDT Tue Jul 17 2018 Currently...radar is becoming more active across the region with scattered showers and thunderstorms over the mountains. Expect this activity to expand across the I-25 corridor this afternoon based on the latest high-res model data. Locally heavy rainfall will be possible along with flash flooding on area burn scars. Temperatures have warmed into the 80s with a few 90s out across the Plains. Through tonight...high pressure aloft will continue to sit over Nevada into Utah while a shortwave trough drops southeast across Wyoming this evening. As the upper level disturbance moves across the region, shower and thunderstorm activity will expand in coverage through the evening hours. High-res model solutions move thunderstorms off the higher terrain, and across the Plains through midnight before dissipating late. Locally heavy rainfall will be the main threat along with lightning. As the storms move across the Plains, hail to near one inch in diameter and wind gusts to near 60 mph will be possible. Overnight lows will remain mild across the region with 50s to lower 60s. Wednesday...the high pressure to the west will remain nearly stationary through the day while the upper disturbance passes into the Central Plains. Broad northwesterly flow aloft will usher in drier air, while a cold front at the surface brings northerly flow to the Plains, cutting off low level upslope flow. Residual moisture and daytime heating will lead to a few showers and thunderstorms over the mountains, however, coverage looks very limited at this time. If one of these storms should hit a burn scar, flash flooding will remain possible, but the threat will be low. Temperatures will start to warm again with highs reaching the mid to upper 90s across the region. Mozley .LONG TERM...(Wednesday night through Tuesday) Issued at 241 PM MDT Tue Jul 17 2018 Center of upper level high pressure slides eastward into Colorado on Thursday, with dry air mass remaining in place across the region. Might be just enough residual moisture for isolated afternoon tsra over the mountains, though storm coverage/intensity looks sparse/weak. As heights build and mid levels warm, max temps Thu afternoon will continue a slow upward climb, with readings 95-105f over the plains, and deep into the 80s across many mountain/interior valley locations. Weak front drops south through the plains Thu night into Fri, with deepening upslope and moisture along/east of the mountains by late Fri afternoon. Mid levels begin to moisten as well, as upper high drifts eastward into the TX Panhandle by Fri evening. Should thus see at least a modest uptick in convection over the area according to the GFS and NAM, while ECMWF is slightly less aggressive with low level moisture return and subsequent convection over the plains. Max temps may drift downward just a degf or two as moisture increases and high slides east, though most locations will still end up somewhat above seasonal averages. Upper high then wanders back westward into the desert sw from late in the weekend into the middle of next week, with at least a modest tap of mid level moisture continuing to drift across the state through the period. Over the eastern mountains and plains, moist air will make periodic southward/westward surges, with perhaps a stronger push on Mon as upper wave moves into the nrn Midwest and surface high builds southward through the plains. Overall, expect sct afternoon tsra both Sat and Sun across the mountains, with wly steering currents taking convection across the I-25 corridor and onto the plains each evening. GFS and ECMWF then point toward Mon/Tue as being particularly wet, as deepening moisture interacts with weak upper energy rotating around the ridge. Temps will continue a slow downward drift through the weekend and into next week as moisture/clouds increase. && .AVIATION...(For the 00Z TAFS through 00Z Wednesday evening) Issued at 241 PM MDT Tue Jul 17 2018 Thunderstorms will be possible through this evening at all three terminal locations. Brief periods of reduced CIGS and VIS are possible as they pass near or over the terminals. Erratic winds are also possible with thunderstorm passage. Expect clearing conditions by late evening as thunderstorms dissipate and move off to the east. If KALS should receive rainfall, fog may be possible later tonight into Wednesday morning. Drier air will work into the area for Wednesday with VFR conditions through the afternoon and no chances for thunderstorms at the terminals. Mozley && .PUB WATCHES/WARNINGS/ADVISORIES... NONE. && SHORT TERM...MOZLEY LONG TERM...PETERSEN AVIATION...MOZLEY

Flash flooding on area burn scars can generate dangerous debris flows along with unstable stream banks. In addition, strong to marginally severe thunderstorms capable of producing hail around one inch in diameter and wind gusts around 60 mph will be possible from this afternoon and evening, favoring portions of El Paso, Kiowa, Bent and Prowers counties. .DAYS TWO THROUGH SEVEN...Wednesday through Monday On Wednesday and Thursday, isolated to scattered afternoon and evening thunderstorms will mostly be confined to over and near the mountains. With limited moisture, the main threats from these storms will be gusty winds and lightning. Starting Friday, atmospheric moisture will increase. Thunderstorms will be capable of producing locally heavy downpours, which can lead to flash flooding on recent burn scars. Storms are possible over much of the region, and the best chances for storms will be over and near the mountains. .SPOTTER INFORMATION STATEMENT... Weather conditions that meet reporting criteria for spotters will be possible through this evening over area burn scars and across portions of the Eastern Plains. 88/88
