NWS Goodland, KS wrote its last area forecast discussion before the first event at Jun 6, 12:02 PM MST, 3 hours 55 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Goodland KS 102 PM MDT Fri Jun 6 2025 .KEY MESSAGES... - Severe thunderstorms are forecast this afternoon and evening, mainly along and south of a line from Yuma County to Gove County between 3-10 PM MDT. Large hail and damaging winds appear to be the primary threats. A brief, isolated tornado is possible. Locations south of Highway 40 are most at-risk. - Fog, perhaps dense is possible again tonight through Saturday morning. - && .SHORT TERM /THROUGH SATURDAY NIGHT/... Issued at 1258 PM MDT Fri Jun 6 2025 The main focus for today will be on the severe weather threat this afternoon and evening. A shortwave is forecast to move off of the Rockies this afternoon leading to strong to severe storms. Stratus across most of the area remains across most of the area but have been seeing some clearing across eastern portions of the area and most notably across Colorado where the main batch of storms is forecast to initiate at. Discrete supercells are the anticipated initial storm mode as wind shear is more than sufficient for storms to remain discrete initially. Any supercells that form will be capable of hail to 2 inches and perhaps a tornado as 0-3 SRH is already around 150-200 m/s. Straight line hodographs are again in place which will support splitting of cells and as this occurs do think an eventual storm mode change to more a cluster becomes most likely with an increasing wind threat this evening as storms move to the southeast along and differential heating boundary. Exactly how far east that will be will be dependent on the amount of clearing from the west that can occur. The severe threat for today looks to be over around 10-11pm MT. The anticipated hazards for today looks to be large to very large hail especially initially due to the strong shear in place along with surface based CAPE of 1000-1500 j/kg. The lacking part of the hail threat is meager lapse rates around 6.5 -7 c/km however recent guidance does have 7-7.5 c/km along and south of Highway 40 which for the most part aligns fairly well with the hatched significant hail threat that is outlined by the Storm Prediction Center and where an intense supercell or two may form. The other potential hail hazard for today will be accumulating hail similar to yesterday as the atmospheric profile is fairly water logged. Should accumulating hail occur then it may lead to some agricultural loss and slick travel conditions similar to snow. At this time think accumulating hail would be more likely to occur than significant hail potential. As storms begin to cluster together due to the straight lined hodographs think an eventual increasing wind threat will evolve out of it. Some weak mid level dryness may be in place with with a 50-70 knot jet in place think some 65-75 mph wind gusts may be able to mix down due to downward momentum transfer. The threat would be able to increase as well especially if any bowing segments can develop. There is some tornado potential as well for today as subtle outflow boundaries remain across the area from yesterdays storms which may help increase this potential especially if a cell can latch on. Similar to concerns from yesterday, am leaning towards the most likely tornado potential will come from merging of storms leading to brief quick spin ups. Some landspouts also can't be ruled out perhaps up to the Kansas/Nebraska line with developing cumulus and as 0-3 CAPE increases. Some localized flooding potential may also be on the table as well especially across Kit Carson, Cheyenne (CO), Wallace and Greeley county where heavy rainfall fell yesterday/last night and SAC-SMA soil moisture still remains. PWATS are again forecast to be in the 1- 1.3 range but with the saturated profile mentioned above do think some periods of moderate to heavy to even torrential rainfall may occur which may lead to some low lying flooding and county road flooding as well. Overall not overly excited about flooding potential as Corfidi upshear and downshear vectors remain high so think clusters will be moving at a decent speed. Drier mid level air is forecast to move in west to east tonight which will bring an end to the rainfall potential. Similar to yesterday I do have some concern about fog developing again overnight and into Saturday morning as winds remain light and variable along with a freshly saturated boundary layer in place. Have went ahead and added in fog into the forecast mainly along and east of Highway 27 as winds are forecast to turn more to the west behind that line which is not climatologically favored for fog. Western CONUS ridging is forecast to develop Saturday leading to warming temperatures in the low to mid 80s. Am starting to see some signs of some storms developing off of the Palmer Divide and potentially clipping Cheyenne county Colorado during the afternoon hours will go with silent pops for now due the strong subsidence with the ridge but may be something to keep an eye on for in upcoming shifts. && .LONG TERM /SUNDAY THROUGH FRIDAY/... Issued at 1258 PM MDT Fri Jun 6 2025 Sunday, a low pressure system is forecast to develop across the northern Plains and send a cold front through the area during the day Sunday. An initial wind shift to the north may occur earlier in the day as a surface trough looks to be in place. Showers and storms remain forecast mainly for western portions of the area in closer proximity to the surface trough and better lift. Severe weather potential is a little iffy at this time as dew points may be marginal at best for the area with the more moist environment being across the southern Plains. Monday and Tuesday, northwest flow returns to the region as the western CONUS ridge reamplifies. Being on the eastern periphery of this ridge may lead to some subtle disturbances which may lead some storm potential but at this range those exact details are not being sampled well. Mid week continue to see some indications of troughing returning suggesting a continued active patter continues for the Tri-State area. Guidance is now suggesting that high pressure develops across the SE CONUS which is typically a signal that moist to very moist air returns to the area. With this pattern the continued wet and active pattern looks to continue. A gradual warming trend looks to continue and peaking mid week as high temperatures in the mid 80s to low 90s. If the moisture does increase like what guidance is suggesting with the surface high across the southeast then temperatures may be a little to high and would need to be lowered as it is more difficult to warm up with higher dew points in place. && .AVIATION /18Z TAFS THROUGH 18Z SATURDAY/... Issued at 1055 AM MDT Fri Jun 6 2025 Stratus continues across most of the area with MVFR to IFR ceilings remaining in place; latest visible satellite imagery does show some pockets of clearing across the region so will need to continue to monitor over the next few hours. Confidence is increasing in showers and storms moving across the area this afternoon and evening; will maintain the PROB30 for now due to boundaries across the area which may play havoc in the rainfall forecast; some storms may be severe with the most likely for severe being at KGLD. Another round of fog and stratus is currently forecast for KMCK with IFR ceilings currently forecast, visibilities may fall lower than what is currently in the TAF but will be dependent on how quickly rainfall moves out of the the area. At this time stratus and visibility reduction should remain east of KGLD. && .GLD WATCHES/WARNINGS/ADVISORIES... KS...None. CO...None.
