NWS Goodland, KS wrote its last area forecast discussion before the first event at Jul 27, 10:09 PM CST, 1 hour 26 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Goodland KS 1009 PM MDT Sat Jul 27 2024 .KEY MESSAGES... - A prolonged period of much above normal temperatures over 100 degrees are forecast Sunday through Thursday. Heat index values of 100 to 105 degrees are anticipated Sunday and Monday with 100 to 110 degrees Tuesday and Wednesday. - Scattered storms developing along the I-25 corridor this aft will track slowly east toward the KS border late this aft- eve. Brief, localized wind gusts up to 65 mph are possible in assoc/w any storms, mainly in northeast CO and adjacent KS-NE border areas between 6-10 pm MDT. - Scattered storms *may* develop over portions of northwest KS and southwest NE Sunday afternoon. An isolated severe storm capable of producing quarter size hail and wind gusts up to 65 mph is possible, mainly between 3-8 pm MDT / 4-9 pm CDT. Low confidence w/regard to whether or not storms will develop. && .SHORT TERM /THROUGH SUNDAY NIGHT/... Issued at 230 PM MDT Sat Jul 27 2024 Today-Tonight: A lingering upper level ridge over the High Plains will further erode today as modest cyclonic flow aloft envelopes the central Rockies. Such a flow regime is relatively more supportive of [1] diurnal lee cyclone development and [2] scattered convective development in climatologically/ topographically favored areas. Expect temperatures similar to yesterday. Current and recent runs of the HRRR and NAM NEST suggest that scattered convection developing along the Colorado Front Range /I-25 corridor/ this afternoon will slowly track east (via weak W to SW steering flow) toward northern portions of the CO-KS border late this afternoon, potentially affecting Yuma-Cheyenne-Dundy counties this evening (~01-06 UTC time frame). In a setup characterized by weak synoptic forcing.. marginal high-based instability (500-1000 J/kg mlcape).. weak low-level/mid-level flow and effective deep layer shear < ~25 knots.. organized convection is not anticipated. The presence of seasonably strong (1300-1600 J/kg) DCAPE suggests that brief, localized severe downbursts are possible in assoc/w *any* high- based convection capable of producing lightning. Expect convective potential to decrease precipitously with eastern extent from the CO-KS border this evening.. where steering flow further weakens, convective inhibition will be increasing (after sunset) and lingering subsidence on the western periphery of a stalled upper level /300 mb/ low (centered invof the eastern KS-OK border) will tend to suppress development. Sun-Sun night: Modest unidirectional /westerly/ flow will envelope the region (in the wake of the recently eroded ridge) on Sunday.. advecting a pristine elevated mixed layer eastward from the Rockies into the High Plains. Profoundly deep vertical mixing (from the surface to 500 mb) will foster the development of a considerable dewpoint gradient /dryline/ over portions of the area Sunday afternoon.. where surface dewpoints may range from the lower 60s (invof Hwy 283) to the teens and 20s (eastern CO). Current and recent runs of the HRRR and NAM NEST vary considerably with regard to low-level moisture distribution over the Tri-State area -- and whether or not isolated convection may develop -- suggesting that convective development may highly depend upon specific aspects of the mesoscale pattern. With the above in mind, expect a conditional potential for isolated severe storms capable of producing damaging winds and/or large hail.. mainly along/east of Hwy 83 and along/north of I-70 in the 21-02 UTC time frame. && .LONG TERM /MONDAY THROUGH SATURDAY/... Issued at 135 PM MDT Sat Jul 27 2024 The long term period continues to be forecast to be hot and relatively dry. The beginning part of the work week continues to have an upper ridge forecast to move over the Plains and amplify. With forecast 850mb temps in the mid 30's C, high temperatures continue to be forecast in the 100's. Mid to upper 100's are looking likely Tues and potentially Wed. Heat index values continue to be forecast around the mid 100's for Tues and Wed, so a Heat Advisory for counties generally along and east of Highway 83 may be needed in the coming days. Otherwise, not much concern for storms with the broad subsidence over the area. Fire Weather concerns for the beginning of the weak are also low. In spite of the dry RHs forecast for the western half of the area, the overall weak flow will be unlikely to have winds or wind gusts exceed 25 mph. For the mid part of the week, guidance continues to suggest a low amplitude trough will move across the Northern Plains from the Northwest CONUS. This would temporarily deamplify the trough and allow for slightly cooler temperatures in the 90's and low 100's. The area would also have some chances for afternoon and evening storms in northwest flow aloft. Will need to watch for critical fire weather as the increase in gradients and flow may allow winds to increase towards 25 mph or greater. Wednesday looks to have the greatest chance depending on how quickly the trough moves through. For the end of the week, the ridge is forecast to reamplify over the Western CONUS and shift into the Plains again. There are a couple of ensemble members that try to swing a trough through the Great Lakes region or quick eject another trough from the northwest. However, neither of these cases seem to be strong signals, so am favoring a fairly quick warm up back into the 100's. The heat will likely continue. && .AVIATION /06Z TAFS THROUGH 06Z MONDAY/... Issued at 1009 PM MDT Sat Jul 27 2024 For KGLD, VFR conditions through the forecast period. Winds, southeast 10-20kts through about 10z then shifting light/ variable. By 16z Sunday, northwest 10-15kts, veering northeast at 10kts by 02z Monday. For KMCK, VFR conditions through the forecast period. Winds, southeast 10-20kts through 12z then light/variable. Around 20z Sunday, a brief period of southeast again 5-10kts before going light/variable again by 00z Monday. && .CLIMATE... Issued at 115 AM MDT Fri Jul 26 2024 July 29 High Temperature Records (F): Goodland......104 in 1947 McCook........109 in 1947 Burlington....100 in 2012 Hill City.....108 in 1917 July 30 High Temperature Records (F): Goodland......106 in 1935 McCook........105 in 2002 Burlington....101 in 2012 Hill City.....109 in 1976 July 31 High Temperature Records (F): Goodland......105 in 2002 McCook........107 in 2002 Burlington....102 in 2002 Hill City.....113 in 1934 Goodland has the potential for 5 consecutive days of highs of 100+ degrees which would tie it for the 14th longest on record. Last time this happened was July of 2012. McCook is also currently forecasted at 5 consecutive days of 100+ degree temperatures which would tie it for 20th all time. However a few days of overachieving temperatures could put them in the top 6 all time. && .GLD WATCHES/WARNINGS/ADVISORIES... KS...None. CO...None.

Scattered thunderstorms may develop over portions of Kansas and Nebraska Sunday afternoon. An isolated severe storm is possible, mainly along and north of Interstate 70 between 3 PM and 8 PM MDT. Quarter size hail, wind gusts up to 65 mph and dangerous cloud to ground lightning appear to be the primary hazards.
