Area Forecast Discussion National Weather Service Cheyenne WY 551 PM MDT Sat Jun 14 2025 .KEY MESSAGES... - The potential for PM strong to severe thunderstorms will be present each day over the High Plains through at least Tuesday. - Warm to hot temperatures are expected over the weekend before a modest cool down on Tuesday. Well above average temperatures are expected to return late in the week. && .SHORT TERM /THROUGH SUNDAY NIGHT/... Issued at 1246 PM MDT Sat Jun 14 2025 GOES satellite imagery shows cumulus clouds already growing over the higher terrain at this time, with mostly clear skies prevailing over the remainder of the area. Our area remains near the axis of the strengthening upper level ridge, but a series of vort- maxes continue to rotate over the top of the ridge, leading to unsettled weather. Southwest flow aloft to our west prevails, pulling in new upper level shortwaves. The closest is apparent on water vapor imagery moving into western Wyoming at this hour. To our east, a more disorganized upper level flow pattern is visible, with a weak surface high over the Great Lakes region continuing to supply plentiful low level moisture to the High Plains. The sunshine, good heating, and ample moisture are setting up potent instability east of the Laramie Range this afternoon. The latest mesoanalysis shows SBCAPE pushing 3000 J/kg just east of the WY/NE state line. We also have very steep mid-level lapse rates in place once again, and slightly higher vertical wind shear compared to yesterday. However, substantial CIN remain in place all across the High Plains. While the surface based CIN should burn off fairly quickly, the MLCIN may linger into the afternoon, similar to what we saw yesterday. Storms are already kicking off thanks to the lifting boost from the terrain and the ripple in the 500-mb flow aloft, with some help from the dryline parked right up against the Laramie range. The Chugwater cyclone is also present today, which should help initiate a storm in northern Laramie county to southern Platte county. While the CIN will initially cause storms to struggle east of the mountains, expect this to be sufficiently eroded by mid afternoon to allow storms to spread east, finally reaching the state line around 4-5PM. Overall coverage will be scattered, with isolated strong to severe storms expected. All severe weather hazards will be possible once again. Low level shear is quite marginal for tornadoes, but it is enough that we can't rule out a few spin-ups. Storms are expected to grow upscale as the evening progresses, but we may see some brief windows for supercell storm modes generally at the beginning of each new storm. Thunderstorms should depart the area by around 10PM, but we may see some lingering shower coverage after midnight until the axis of the subtle shortwave clears the area early Sunday morning. The upper level ridge will amplify somewhat heading into Sunday, leading to temperatures a few degrees hotter compared to today. Lingering cloud cover should clear out by daybreak, allowing for quick heating. Yet another ripple in the flow aloft will pass north of our area on Sunday, with a trailing axis of vorticity to the south that should help kick off another round of PM showers and thunderstorms. The dryline position may end up a little further east than where it is located today thanks to the surface high getting nudged a little further away from the area. Expect the afternoon strong to severe weather threat to rinse and repeat for Sunday afternoon and evening, with a similar setup once again. However, there may be a slight east shift in the main area for storms thanks to the dryline getting nudged closer to the WY/NE border by the mid to late afternoon hours in some models. This is a little uncertain though, as models have generally been too progressive in pushing the dryline eastward the last several afternoons. && .LONG TERM /MONDAY THROUGH SATURDAY/... Issued at 1246 PM MDT Sat Jun 14 2025 The severe thunderstorm chances continue through mid- week next week. Monday, An upper level low pushes through the Pacific Northwest sending a trough through our Intermountain west. This trough will inherently flatten our ridge as it moves through the high plains. Accompanying this trough will be a few vort-maxes to help amplify our severe potential. East of I-25 the airmass has a little bit more moisture to play with so this will be the likely domain our severe weather will occur. Due to the southwest flow of the ridge, temperatures are expected to be in the mid to upper 80's allowing us to break the morning cap. Model soundings indicate MUCAPE will be around 3,000 joules with 2000 of that being MLCAPE. Lapse rates will be around 9C creating a very unstable and energized environment. SPC has dropped a level 2 out of 5 Slight Risk for majority of the Northern portion of our CWA with a Marginal Risk for the southern portion. The only parameter that's in our favor is the 36 knots of effective shear which gives us a pulsy messy storm type for the afternoon and evening. This trough passage also sets us up for severe weather chances on Tuesday. Model guidance (3 globals) depict some cyclogenesis occurring TUesday developing from this passage. If cyclogenesis occurs this will likely provide enough synoptic support to kick start some storm development in the afternoon. However, we will have a little bit less energy but a little more moisture to play with on Tuesday. MUCAPE is set at 2000 joules with 1800 of that being MLCAPE. Model soundings are showing a very pronounced inverted V sounding indicative of severe winds with 687 joules of DCAPE. Once again our effective shear is a little lower with a progged speed of 26 knots. Again there are a couple progged lobes of vorticity allowing some enhancement of the storms as well. Wednesday, we may catch a little bit more of a break as more dry air starts to filter in as we become into a Northwest flow type of pattern. There does look to be a shortwave however our temps will be a little cooler in the 70's and there wont be a whole lot of support for severe chances especially in downsloping flow as we start to really develop a more stout dry layer near the surface. MUCAPE is 500 joules which is plenty of energy still to develop a thunderstorm especially with 42 knots of alleged shear. However, if theres no moisture to lift than we wont get any development. Wednesday, will be still be a good day to keep an eye on for severe weather as well. && .AVIATION /00Z TAFS THROUGH 00Z MONDAY/... Issued at 551 PM MDT Sat Jun 14 2025 Skies are still expected to clear after the line of storms and showers move through this evening. Winds are expected to be more southwesterly for our Wyoming terminals and southerly for our Nebraska terminals. Once again showers and thunderstorms are expected to develop between 21z and 23z and should be done around 04z according to hi-res guidance consensus. && .CYS WATCHES/WARNINGS/ADVISORIES...
