743 FXUS63 KEAX 261730 AFDEAX Area Forecast Discussion National Weather Service Kansas City/Pleasant Hill MO 1130 AM CST Wed Nov 26 2025 ...18z Aviation Update... .KEY MESSAGES... - Gusty winds continue with gusts around 20-25 MPH, isolated 30+ MPH expected. - Dry and below normal temperatures continue through the Thanksgiving holiday. - Confidence is increasing in impactful weather for the weekend after Thanksgiving. Rain, mixed precipitation, and snow are possible. Both road and air travel are likely to be impacted. && .DISCUSSION... Issued at 417 AM CST Wed Nov 26 2025 Water vapor imagery continues to show a compact low pressure system working its way to the east. This system opened the gates for strong cold air advection from interior Canada. Much of this advection could be felt overnight as winds remained fairly stout around 10-15 MPH with pre-sunset gusts approaching 30-40 MPH. As this system exits the region, winds settle back down; however, gusts around 20-25 MPH persist as midlevel flow mixes to the surface. Cold air remains in place with highs today only reaching the low to mid 40s, which are below seasonal averages. Ridging build through the afternoon and evening keeping sunshine around and maintaining the flow of cold air into the region. A weak perturbation in the flow might develop some flurries across central KS, but these are expected to remain west and south of our area. Dry and cool conditions are expected to continue through the Thanksgiving holiday. Another strong compact system is expected to move on shore in the Pacific northwest on Thanksgiving Day. This system will act as the catalyst for a pattern shift into more wintry weather starting Friday lasting into early next week. On Friday, the synoptic trough begins to traverse the Rocky Mountains sparking off a lee trough which taps into the flow of moisture and relatively warmer air setup up by the ridge ahead of it. This results in a large shield of precipitation forming around the frontal boundaries starting first across the upper Midwest, where snow is likely to develop, followed by more filling in across the southern CONUS as the storm matures. Ensemble guidance continues to favor much of the area being in the warm sector of this cyclone as temperatures in the 40s creep toward the US-36 corridor. North of that, lower temperatures favor the development of accumulating snow across far northeast MO. Ensemble guidance members have been gradually increasing mean snow total with most members averaging out to around 2-3 inches of snow across the spread. Temperature forecasts have been sliding slightly lower with each successive model run; so, it tracks that snowfall totals might increase. With that, it is looking more likely that points south and west of the accumulating snow will see snowfall; however, temperatures look to remain warm enough to limit the ability of snow to accumulate. Confidence is increasing in general travel impacts for the post- Thanksgiving holiday travel period. While snowfall coverage looks to be fairly limited at this point, rain and wintry mix will likely cause driving difficulties and could impact inbound and outbound air travel. Precipitation is expected to increase Saturday with the primary uncertainty being the location of the warm ad cold sectors of the storm. The synoptic picture looks to show the center of the system moving through the KC Metro which puts the warm front up towards the Kirksville area with the cold side residing north and west near Omaha. As the cold side of the system progresses through the region Saturday afternoon, it would not be surprising to see some snowfall and even potential accumulation on grassy areas. Ensemble guidance puts >0.1 inch snow accumulations at around 20% for the KC metro and 40% for the greater St. Joseph metroplex. Precipitation rolls out of the area Saturday evening yielding a dry, cold Sunday where any travel disruptions from Friday and Saturday could rectify. Extended model guidance throws out another chance for snow Monday. Another wave looks to move through bringing chances for snowfall across southern KS extending into MO along and south of I-70. The synoptic pattern looks to be much more favorable for pure snowfall. Deterministic guidance paints a potential of 1-2 inches of snow with this band; however, many uncertainties remain, especially because long range deterministic guidance is heavily affected by short term fluctuations. Ensemble guidance is not quite as bullish with location and snowfall predictions which makes sense as the suite of model members put out a wide range of scenarios. Beyond Monday, guidance places several more waves in the flow keeping the pattern active. The southern boundary of the polar air mass looks to settle across the Ozarks and Ohio Valley firmly establishing a pattern shift towards winter. && .AVIATION /18Z TAFS THROUGH 18Z THURSDAY/... Issued at 1128 AM CST Wed Nov 26 2025 Currently gusty NW winds will gradually ease through the day today. By or just a bit after 00z this evening, winds will ease back to around 5kts across the sites, but largely remain out of the NW. A mid-level cloud deck (8-10kft or so) will glide through, and is not expected to produce anything other than said cloud cover. Takeaway... VFR conditions expected throughout this period. && .EAX WATCHES/WARNINGS/ADVISORIES... MO...None. KS...None. && $$ DISCUSSION...CDB AVIATION...Curtis
