788 FXUS63 KGLD 101714 AFDGLD Area Forecast Discussion National Weather Service Goodland KS 1014 AM MST Mon Nov 10 2025 .KEY MESSAGES... - Continued dry forecast through the week until next weekend. - Gradual warming temperature trend through the work week. - Low relative humidity Tuesday and Friday with breezy winds leading to some fire weather concerns. && .SHORT TERM /THROUGH WEDNESDAY NIGHT/... Issued at 1236 AM MST Mon Nov 10 2025 A surface high is located across eastern portions of the forecast area where single digit dew points have filtered in. A combination of the surface high and low dew points have lead temperatures fall into the low to mid teens currently with the potential to fall into the single digits by Monday morning. Further to the west some subtle troughing is nosing in allowing winds to become more south- southwesterly which is forecast to keep temperatures from falling below the upper teens. Throughout the remainder of the day the trough is forecast to continue moving through the area leading to breezy sustained winds around 15 mph. Winds are forecast to remain from the southwest leading to some downsloping allowing temperatures to warm up, especially across the west where low to mid 60s are forecast. The high pressure across the east will be slow to move out as temperatures may struggle to get out of the 40s. Monday night and into Tuesday morning, a shortwave is forecast to move across the area from the Cheyenne ridge. As the shortwave moves across the area winds are forecast to become breezy from the west- northwest due to an increasing 850mb jet as a result this is anticipated to help keep temperatures at or above freezing for the majority of the forecast area as the lower levels of the atmosphere remain mixed. Tuesday, breezy to even gusty conditions will be ongoing as the nocturnal inversion breaks with sustained winds of 15-25 mph gusting to 35 mph with the strongest across eastern Colorado. Some lower dew points in the mid teens to low 20s will remain across eastern Colorado as well as temperatures rise allowing humidity values to fall into the mid teens to low 20s resulting in some elevated to even critical fire weather conditions across Cheyenne and Kit Carson counties but may even spread into Wallace and Greeley counties as well. Winds are actually forecast to decrease starting around 19Z or so as the shortwave moves out of the area allowing the 850mb jet to weaken. Higher dew points are also forecast to move in from the north which this along with the declining wind brings some questions on how many hours of critical conditions can occur leading to a confidence of 20-25% for 3 or more hours of critical conditions (highest for Cheyenne county Colorado) which is to low to validate a need for a Fire Weather Watch at this time. Confidence though in 1-2 hours of critical conditions is around 30-40% especially the further west across Cheyenne county Colorado you go. Wednesday is forecast to be another warm day as ridging across the western CONUS returns leading to above normal temperatures in the 70s for most of the area as breezy southwest winds continue. Dew points are forecast to be higher in wake of the weak moisture advection from Tuesday afternoon helping to mitigate fire weather concerns. The southwest winds are forecast to continue through the night as larger scale troughing across the Pacific ocean begins to take shape helping temperatures remain above freezing again. && .LONG TERM /THURSDAY THROUGH SUNDAY/... Issued at 300 AM MST Mon Nov 10 2025 Thursday-Friday: An amplifying upper level trough in the Pacific will move ashore the Pacific Coast (Thu) and progress east across the Intermountain West (Fri). Meanwhile, in advance of the aforementioned trough, an upper level ridge will prevail over the Central Plains. Ridging aloft and modest southerly low- level flow on the eastern periphery of a persistent surface trough in the lee of the Rockies will foster dry conditions and well-above average highs in the lower-mid 70`s. Strengthening S-SW low-level flow on the eastern periphery of a developing (albeit broad) surface to 850 mb trough in the lee of the central Rockies may foster breezy S to SW winds (and adverse fire weather conditions) across portions of the area on Friday, depending on whether or not (and if so, to what extent) increasing upper level cloud cover -- orographically enhanced cirrus, in particular -- impacts diurnal heating and vertical mixing. Saturday-Sunday: Below average forecast confidence*. 00 UTC 11/10 operational runs of the GFS and ECMWF are in better agreement (compared to 24-hr ago) with regard to the evolution of a complex longwave trough over the western and central CONUS this weekend. Both suggest that the longwave trough will fracture over the Intermountain West (Fri-Fri night).. the southern portion of which will evolve into a closed low that progresses ESE from the Desert Southwest (Sat) to central Texas (Sat night) then E to the Lower Mississippi River Valley (Sun) and.. the northern portion of which will manifest as a less amplified/deep, progressive trough over the northern CONUS. A perfect prog of either (GFS or ECMWF) solution would suggest dry conditions and near-average (Sat) to slightly below-average (Sun) temperatures in the NWS Goodland county warning area, however.. given the complex nature of the synoptic pattern and distant forecast range (132-168 hours out), it would be unwise to take any model solution at face value. Broadly speaking, an approaching longwave trough in an amplified synoptic pattern suggests an above-average potential for active weather (in some form or another). *Forecast confidence typically decreases with range. `Below average`, in this context, is intended to communicate a further reduction in confidence associated with /inherent to/ increased pattern complexity.. e.g. patterns characterized by cut-off waves, multibranched jet/wave interactions and potentially significant forms of constructive/destructive interference, among others. && .AVIATION /18Z TAFS THROUGH 18Z TUESDAY/... Issued at 1012 AM MST Mon Nov 10 2025 VFR expected to prevail at both KGLD and KMCK through the TAF period. Southerly surface winds will gust up to 20 kts at times through this afternoon, diminish tonight, then increase again from the northwest mid to late Tuesday morning. && .FIRE WEATHER... Issued at 1236 AM MST Mon Nov 10 2025 A period of elevated to critical fire weather remains forecast from late morning Tuesday through the early afternoon across Kit Carson county, Cheyenne county Colorado along with western Wallace and Greeley counties in Kansas. An interesting fire weather conditions setup is forecast to take shape as a shortwave moves across the area during the morning hours leading to the breeziest winds occurring from between 8am-11am MT with sustained winds of 20-30 mph and gusts up to 35 mph forecast. A corridor of lower dew points is also forecast to move through as well dropping humidity values into the mid teens to low 20s as early as 10am MT as temperatures rise into mid 60s to low 70s. The tricky part of the forecast is that the winds will actually decline as the afternoon goes on and humidity increases leading to a brief window from the late morning into the early afternoon where critical fire weather conditions may exist. Peak mixing heights during the afternoon are forecast to be around 5000 feet which is forecast to be nearing a wind field of 20-25 knot winds which leads me to believe that any wind gusts of 25 mph or higher will be spotty and sporadic. Confidence in achieving an hour or two of critical conditions is around 30-40% mainly in western Cheyenne county Colorado and 20-25% of 3 or more hours. In the other counties mentioned 1-2 hours of critical conditions is around 20-25% and 3+ hours is 10-15%. Am opting to hold off on any fire weather products at this time due to the lack of confidence in achieving 3 or more hours of critical conditions and due to the overall limited spatial nature of where the critical conditions are forecast. Nevertheless be extra cautious with any activity that involves sparks Tuesday morning as GFDI (Grassland Fire Danger Index) values are forecast to be very high from 45-55 along with drying 10 hour fuels approaching 10% according to the Kansas Mesonet across most of northwest Kansas. && .GLD WATCHES/WARNINGS/ADVISORIES...
