760 FXUS63 KGLD 222046 AFDGLD Area Forecast Discussion National Weather Service Goodland KS 246 PM MDT Wed Jul 22 2026 .KEY MESSAGES... - Scattered storms are expected during the late afternoon and evening hours today and Thursday. Localized wind gusts up to 65 mph and locally heavy rainfall are possible on both days. - Triple digit temperatures are likely to return to most of the area this weekend. Heat indices in the mid-100s are possible Saturday through Monday, increasing the risk for heat related illnesses. && .SHORT TERM /THROUGH FRIDAY NIGHT/... Issued at 110 PM MDT Wed Jul 22 2026 Today-Tonight: Surface high pressure anchored over the Upper Midwest will help maintain breezy ESE to SSE low-level flow across the majority of the Tri-State Area today. Expect sensible weather conditions similar to, albeit several degrees warmer than, yesterday, with highs ranging from the lower 90`s in northeast portions of the area to upper 90`s in southwest portions of the area, perhaps 100F in Tribune. While a pronounced upper level ridge persists over the region, the core of the ridge has shifted further south, over the Southern Plains (TX-OK), resulting in a less-suppressed convective environment compared to yesterday. Weak SW to W flow aloft persists. Recent (07/22) 12Z runs of the HRRR and NAM NEST continue to suggest that low-level convergence and ESE-SE upslope flow on the east and northeast periphery of a well defined lee cyclone in CO will lead to late afternoon high-based storm development along the Colorado Front Range, Palmer Divide and southeast CO, in an environment characterized by marginal instability, weak low- level flow and weak effective deep layer shear. With this in mind, expect convection to be unorganized and slow-moving in nature. Inverted-V thermodynamic profiles and seasonably strong DCAPE (1400-1800 J/kg) will, nonetheless, support a potential for brief, localized wind gusts up to ~65 mph with any deep updrafts. HRRR and NAM NEST simulated reflectivity forecasts suggest that convection emanating from the Colorado Front Range and Palmer Divide will slowly track east into far western Kit Carson/Cheyenne counties ~01Z (7 pm MDT), that storm coverage will be greatest between 02-07Z (8p-1a MDT) and that storms will largely be confined to eastern CO (west of Hwy 27). Environmental conditions become less supportive of convection with eastern extent from the CO-KS border, especially after ~02Z, as convective inhibition rapidly increases after sunset. Thu-Thu night: Synoptically similar to today, albeit with modestly stronger WNW flow aloft on the eastern fringe of an amplifying ridge over the 4-Corners and northern Rockies. Expect sensible weather conditions similar to today. Precipitation chances will, once again, be tied to upstream development along the CO Front Range, Palmer Divide and Raton Mesa, suggesting that locations west and south of Goodland are more (or most) likely to see precipitation. Given that late evening and early morning convection over and upstream of the Tri-State Area may modify environmental conditions, low confidence persists w/regard to thunderstorm coverage and evolution. Inverted-V thermodynamic profiles and seasonably strong DCAPE will, once again, support a potential for localized wind gusts to ~65 mph. With relatively stronger WNW flow aloft over the region, a somewhat greater damaging wind potential may exist if convective evolution leads to clusters or linear organization and cold pool consolidation. Fri-Fri night: Guidance indicates that the amplifying ridge over the 4-Corners will expand eastward across the Rockies and Central/Southern Plains. Expect dry conditions and light winds with highs in the mid 90`s. && .LONG TERM /SATURDAY THROUGH WEDNESDAY/... Issued at 239 PM MDT Wed Jul 22 2026 GEFS and EC 500-mb height mean-spread guidance is supportive of a longwave upper-level ridge centered across the High Plains for the entirety of the long term period. The feature appears strong enough that shortwave troughs from the Aleutian Islands will be redirected northeastward before they encroach into the United States. However, broad surface lows in association with these troughs look to favor southerly surface flow across the forecast region at least through Sunday night. Hot conditions appear favored over the weekend, with highs forecast in the mid 90s to lower 100s Saturday, and upper 90s to mid 100s Sunday. Heat index values in the mid 100s are possible, especially Sunday along and east of Kansas Highway 25 where dew points in the upper 50s to lower 60s are possible. NBM guidance suggests over a 90% chance for much of Northwest Kansas and Southwest Nebraska to experience temperatures over 100 degrees Sunday afternoon. Confidence in a Heat Advisory being needed Sunday is around 30%. In addition to the hot weather, dry conditions are forecast as well. Relative humidities (RH) are forecast to be low, especially on Sunday when they drop into the upper teens across portions of Eastern Colorado. Even so, critical fire weather conditions are not yet a concern, as wind gusts are forecast to max out in the low to mid 20 mph. NBM guidance suggests a 20% chance or less across Eastern Colorado that wind gusts will meet critical fire weather criteria (25 mph or greater). As such, confidence in a Red Flag Warning being needed across this zone is less than 5%. GEFS 850-mb height mean-spread guidance shows a stationary low developing across portions of Utah and Colorado Monday. This may allow for showers and thunderstorms to return to the area Monday through Wednesday. NBM 24 hr precipitation guidance shows the highest chances to receive greater than 0.1 inches of precipitation across Eastern Colorado, with some areas over a 40% chance each day. Thunderstorms are not favored to become severe during this period, as GFS and EC model soundings show 0-6km shear maxing out around 30 kts. However, it may be important to note that GFS soundings are showing a deep inverted-V profile up to nearly 500-mb. If thunderstorms could occur with this sounding profile, microbursts would be possible, with a chance of experiencing severe winds. Confidence in severe weather occurring is about 5% for each day Monday through Wednesday. Temperatures in the mid 100s may continue into Monday as well. NBM guidance suggests between a 70-90% chance for temperatures to rise above 100 degrees. Confidence in a Heat Advisory being needed Monday is around 15%. High temperatures begin slightly dropping on Tuesday into the mid 90s to lower 100s, and low to mid 90s Wednesday, which would dramatically decrease the likelihood of further Heat Advisories. && .AVIATION /18Z TAFS THROUGH 18Z THURSDAY/... Issued at 950 AM MDT Wed Jul 22 2026 GLD: Aside from a potential for sub-VFR conditions associated with scattered thunderstorms this evening (~02-06Z), VFR conditions will otherwise prevail through the TAF period. SE winds at 15-20 knots with gusts to 25-30 knots are expected through the afternoon. SE winds will back to the ESE and increase to 25 knots with gusts to 35 knots shortly before sunset (01-02Z) and persist for several hours before decreasing to 15-20 knots overnight. 15-20 knot E to SE winds will prevail thereafter, through the remainder of the 18Z TAF period. MCK: Aside from a potential for sub-VFR conditions associated with scattered thunderstorms late this evening and overnight (~04-09Z), VFR conditions will otherwise prevail through the TAF period. SE winds at 13-18 knots will occasionally gust up to 25 knots this afternoon. Winds will back to the ESE around sunset and decrease to 10-15 knots late this evening and overnight. 10-15 knot E to SE winds are expected to prevail through the remainder of Thu morning. && .GLD WATCHES/WARNINGS/ADVISORIES...
