Area forecast discussion, Aug 14, 1:59 PM MST, 6 hours 1 minute before
Area Forecast Discussion National Weather Service Pueblo CO 259 PM MDT Wed Aug 14 2019 .SHORT TERM...(This evening through Thursday) Issued at 238 PM MDT Wed Aug 14 2019 Some isolated showers/tstms will be possible into the early evening over the mtns and high valleys, but the I-25 corridor and eastern plains will be the main focus area for storms this evening as a weak weather disturbance moves across the area. Isolated to scattered storms are expected across portions of the I-25 corridor and plains, with the are east plains likely see the best chances. The HRRR shows only some isolated storms, The NAM Nest has a little more coverage over the plains, with the potential for some strong storms early in the evening over Otero and Bent Counties, and then after about 7 pm, some strong storms moving into Kiowa and eastern Prowers Counties. The earlier run of the NAM has showers/tstms continuing over the far southeast plains into the late night hours, but the 18Z run, as well as the lastest HRRR, shows activity ending by about midnight or 1 AM. SPC still has the southeast plains outlooked for the possibility of severe storms, with the main threats being large hail and damaging wind gusts, but with shear values of 40+ kts cannot rule out an isolated tornado. On Thu a northerly surge moves through eastern CO by around midday, and conditions look drier. Dew points this afternoon over the southeast plains are in the 50s, but Thu afternoon they are expected to drop into the 30s along the I-25 corridor, with some lingering lower 50s over the eastern border area, while over the high country dew points should be mostly in the 20s to lower 30s. There will likely still be a be enough moisture and instability for a just a few showers and tstms. Temps on Thu will be warmer across the plains, with 90s for highs, with some locations along the Arkansas River Valley see highs nearing 100. The San Luis Valley and the Upper Arkansas River Valleys should see highs in the lower to mid 80s. .LONG TERM...(Thursday night through Wednesday) Issued at 238 PM MDT Wed Aug 14 2019 Flat westerly flow across the area will keep best mid level moisture shunted fairly south of the region into the weekend, before upper ridge amplifies over the Rockies early next week, leading to a brief influx of deeper moisture Tue/Wed. Beginning with Friday, low level moisture in place across the plains early mixes eastward by late day, though perhaps just enough instability/moisture linger for isolated afternoon/evening convection along and east of the mountains. Best chance for a stronger storm would be over the far east and up into nern CO, where greater instability will reside. Sat will features a low risk of some high based storms over the mountains and Palmer Divide Sat as upper wave slides by to our north, while max temps begin to creep back upward a few degf at many locations. Sun/Mon look dry and hot, with only some very isolated weak convection possible over the mountains Mon afternoon. Moisture returns Tue/Wed under building high pressure aloft, with thunderstorm chances increasing both days, especially across the mountains. Max temps will remain warm, with lower Ark Valley again near 100f both days. && .AVIATION...(For the 00Z TAFS through 00Z Thursday evening) Issued at 238 PM MDT Wed Aug 14 2019 Showers and thunderstorms will be possible thru early this evening at KALS, KCOS and KPUB. If storms do move into the vicinity of a terminal forecast site, the main threats will be gusty outflow winds and lightning. Otherwise, VFR conditions are expected. Otherwise VFR conditions are expected tonight and Thu. Chances for showers and thunderstorms look lower on Thu. && .PUB WATCHES/WARNINGS/ADVISORIES... NONE. && SHORT TERM...28 LONG TERM...PETERSEN AVIATION...28
