Area forecast discussion, Jul 30, 4:02 PM MST, 3 hours 10 minutes before
Area Forecast Discussion National Weather Service Pueblo CO 502 PM MDT Thu Jul 30 2020 .SHORT TERM...(This evening through Friday) Issued at 502 PM MDT Thu Jul 30 2020 Cold front dropping through the area today, with gusty north winds on the plains gradually turning easterly as of mid-afternoon. Starting to see some isolated tsra on the plains as moisture increases behind the boundary, and thus expanded at least isolated pops over the eastern mountains and all of the southeast plains into early evening. While best dynamic lift should be over the far eastern plains near departing upper trough, low level easterly upslope and modest (CAPE 500-1000 j/kg) instability may force some convection over the southeast mountains, with storms moving s-se this evening. Several CAMs have picked up on this, so will maintain low pops through roughly 10 pm-midnight before activity dies off. On Friday, slightly deeper moisture/instability in place across the area with low level easterly flow, while brisk n-nw flow aloft persists. Should see greater coverage of afternoon tsra, with models pointing toward greatest chances along the srn Sangres. Storms may have a tough time moving much farther east than I-25, given N-S steering currents. Max temps look little changed from Thu, with seasonable late summer readings at most locations. .LONG TERM...(Friday night through Thursday) Issued at 502 PM MDT Thu Jul 30 2020 Friday night through Monday... Northwest flow will continue over the area through the weekend thanks to the high pressure present at upper levels to our southwest. At the surface, easterly upslope flow will persist over the plains. This will supply needed moisture as well as a healthy amount of deep layer shear for potential thunderstorm development through Monday. The strength of potential storms will largely depend on the timing of the easterly influx of moisture during the day. Saturday's potential activity will likely be placed later in the afternoon (21-03Z) mostly confined over the mountains, thanks to a strong influx of moisture aloft during the day. Sunday is consistently more wet in the models, and while activity is most likely over the southeastern mountains, storms may progress SE towards some areas of better CAPE (models are typically sitting around 2000 or so 21-00Z) so there's a likely chance those areas could see some hail and gusty winds as well. Flash flood threat is less widespread, although if isolated, stronger storms manage to drift over a burn scar heavier rains could pose an issue. However based on the last few model runs this convection should quickly drift south of our area, but will keep some pops around on the southern border. With the upper level high and northwest flow aloft persisting with the easterly upslope flow and daytime heating, the area will continue to moisten through Monday, spawning more chances of daily afternoon thunderstorms. Tuesday through Thursday... A ridge settles over CO on Tuesday, locking in some of the remaining moisture for a chance at another round of thunderstorms during the afternoon, although they should be less widespread compared to the weekend. On Wednesday the high pressure will shift to our south and move east slightly, giving us more southwesterly flow aloft into the area and a blast of some monsoonal moisture, leading to some more pops over the mountains. The GFS has the region drying out a fair bit Wednesday and Thursday, while the Euro seems a little more optimistic about incoming moisture. Will keep existing pops for the afternoon hours both days. -MG && .AVIATION...(For the 00Z TAFS through 00Z Friday evening) Issued at 502 PM MDT Thu Jul 30 2020 VFR conditions at all terminals the next 24 hrs. Low risk of a vcts at KCOS and KPUB from 23z-03z, and may need a vcts at KPUB for a few hours given current radar trends. Gusty north winds will become easterly this evening at all sites, before weakening by 06z. Slightly more convection over the mountains on Friday, with a vcts possible at all terminals after about 20z as activity drifts toward lower elevations. && .PUB WATCHES/WARNINGS/ADVISORIES...

First, stronger storms are possible near the Kansas border, mainly this afternoon. These storms will be capable of producing half inch hail, gusty winds to 45 mph, lightning and locally heavy rainfall. Back over the Eastern Mountains, east into the Interstate 25 corridor, isolated to scattered thunderstorms are also possible from late afternoon into the evening. Gusty outflow winds to near 40 mph and lightning will be be possible these storms. .DAYS TWO THROUGH SEVEN...Friday through Wednesday Scattered thunderstorms will be possible each day in and near the mountains for Friday through Monday with thunderstorms expected to become more numerous for Sunday and possibly Monday. The main risk with thunderstorms will be gusty winds up to 45 mph small hail up to 1/2 inch in diameter and lightning. Locally heavy rainfall will be possible, especially Sunday and Monday. These days will have the greatest risk for flash flooding on area burn scars should a stronger storm impact these locations. Drier air will spread into the region for Tuesday and Wednesday with thunderstorms becoming less widespread. Gusty winds and lightning along with spotty light to moderate rainfall will be possible these days. .SPOTTER INFORMATION STATEMENT... Weather conditions that meet reporting criteria for spotters will be possible this afternoon and evening near the Kansas border. 10/31
