The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Goodland, KS wrote its last area forecast discussion before the first event at Jun 7, 4:06 PM MST, 14 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Goodland KS 506 PM MDT Fri Jun 7 2024 .KEY MESSAGES... - Severe weather is possible this afternoon and evening with hail up to two inches, and wind gusts up to 70 mph. Overall storm chances are around 65%. Severe weather is expected to be more isolated to scattered, not widespread across the area. - Another round of severe weather looks likely with 1.5-2 inch hail, 60-70 MPH winds, and excessive rain leading to flooding concerns. - Active weather pattern continues Sunday through Tuesday with similar trend of storms moving in from the west during the afternoon/evening. - Potential break in the active weather pattern mid week with near triple digit temperatures. && .UPDATE... Issued at 331 PM MDT Fri Jun 7 2024 Storms firing off of the dryline near highway 25 and in western Cheyenne county in Colorado are in an environment that will promote explosive growth of storms. This could lead to storms producing hail around 2 inches in diameter and winds nearing 75 MPH. This has prompted a Severe Thunderstorm Watch to be issued for a large portion of the CWA. && .SHORT TERM /THROUGH SATURDAY NIGHT/... Issued at 106 PM MDT Fri Jun 7 2024 This afternoon, there is a 500mb high pressure system sitting in New Mexico/Texas with a low pressure system over the Great Lakes. A shortwave is forming in northeastern Colorado and will move over the CWA over the next few hours, allowing an 850mb lee low to form in eastern Colorado. The lee low will move on east, bringing a weak cold front with it. The FROPA will be leaving eastern Colorado around 20-21Z, convection is expected to form in its wake. The convection will continue to fire along/behind the FROPA in clusters and are generally expected to be elevated across most of the CWA, as evident with inverted-V soundings. There will be plenty of instability, around 2,500-3,500 J/kg of MUCAPE and shear will be plentiful with 40-50 kts of effective wind shear. Hail will be the primary threat throughout most of the CWA, but winds up to 70-80 MPH could be possible in the far eastern CWA as storms collapse with over 1,500 J/kg of DCAPE, potentially as a downburst. The storms most likely to produce severe weather will be in Kansas, and along and north of I-70. Storm motion looks to be fairly quick north of I-70, with 40-60 kts of downshear velocities. Storms look to leave the area around 6-9Z to the east/northeast. Overnight temperatures will be kept fairly warm due to lingering cloud cover, only allowing temperatures to cool down to the lower 60s. The cloud cover will stunt warming up tomorrow, too. However high temperatures tomorrow look to warm into the upper 70s to mid 80s. Temperatures will be the warmest in the southern CWA tomorrow, which will aid in convective storms. In the upper and mid levels, tomorrow's setup looks very similar to today's; a shortwave creating a lee low. The biggest difference will be the convection looks to occur a couple hours later in the day and we will have northeasterly moisture return during the day ahead of the storms. The convective parameters are noticeably different for tomorrow though. Instabilty is reduced tomorrow, with "only" 2,000- 2,750 J/kg MUCAPE, with a long, skinny CAPE profile, and PWATS over 1.3 inches. Although the instability is a little high for ideal parameters, the soundings look primed for excessive rainfall and flooding. Downshear velocity is still around 50 kts, however CAMs are suggesting this event will turn into a large cluster or MCS event. These storms could produce hail around 1.5 inches and wind gusts around 60-70 MPH. Over the past 12 hours, the models are showing the lee low has shifted north into the GLD CWA. My confidence is not high (~35%) it will remain this far north, but will instead shift back south where it has been showing. With the northern track, Wallace county looks to be at the highest risk for excessive rainfall, but with the southern track, Wichita county is the focus. Either way, there is a risk for excessive rainfall leading to flooding tomorrow. Storms look to move in around 21Z and last until 9-12Z. Tomorrow's low temperatures will cool into the mid to upper 50s. && .LONG TERM /SUNDAY THROUGH FRIDAY/... Issued at 106 PM MDT Fri Jun 7 2024 This general upper and mid level pattern continues into Tuesday, giving us a diurnal chance at showers and storms. Monday does look to have a slightly more developed 500mb low sweeping across the area, so we will need to keep a close eye on the severe potential for Monday evening. Sunday and Monday will be cooler with temperatures remaining in the 70. Tuesday, the cloud cover looks to break and we will warm into the 80s again After Tuesday, a ridge looks to extend over the CWA and work to lower convective chances. This ridge will also usher in hot temperatures and by Thursday, numerous locations could be looking at triple digit heat. At the end of the long-term, we are seeing signs of an upper-level trough cutting into the region that could bring precipitation and cooler temperatures. Details are not clear yet about this system, but we will be keeping an eye on it. Throughout the long-term, low temperatures range in the mid 50s through upper 60s. && .AVIATION /00Z TAFS THROUGH 00Z SATURDAY/... Issued at 502 PM MDT Fri Jun 7 2024 Main focus will be on showers and storms across the area which will remain isolated to scattered. Watching for the potential for strong to damaging wind gusts at the KGLD terminal as outflow emanating from cells in northeast Colorado should help strengthen the showers and storms currently across Kit Carson county. Supercell to the west of KMCK shouldn't directly impact the terminal other than lightning being the main threat. Off and storms look to occur for the majority of the evening. Fairly good consensus in low stratus affecting each terminal tomorrow before another round of storms moves in from the west. && .GLD WATCHES/WARNINGS/ADVISORIES... KS...None. CO...None.
