094 FXUS63 KLBF 302112 AFDLBF Area Forecast Discussion National Weather Service North Platte NE 312 PM CST Sun Nov 30 2025 .KEY MESSAGES... - Light snow is possible tonight mainly across the southern third of the forecast area or generally south of a line from Oshkosh to Bartlett. Snow accumulations of around an inch is possible with the heaviest amounts south of Interstate 80. - Temperatures will return to near normal levels with daytime highs generally in the 30s. Highs Tuesday, Friday and Saturday may reach into the lower to middle 40s. - Another round of snow is possible Tuesday night into Wednesday mainly over far western and northwestern portions of the forecast area. ATTM, only light accumulations are possible. && .SYNOPSIS... Issued at 312 PM CST Sun Nov 30 2025 H5 analysis this morning had a broad longwave trough centered across the entire CONUS. Within this longwave trough two distinct shortwave features were present across the lower 48. The first feature was a shortwave trough located over the LP of Michigan. This was part of a trough which extended from Hudson Bay south into the lower Ohio Valley. A secondary shortwave within this trough of low pressure was located over northern Minnesota into northeastern South Dakota. This feature had spread low cloudiness and light snow to northeastern portions of the forecast area this morning. West of this trough complex, a second strong shortwave, was located over southern Idaho. As of midday this feature was located over northern Utah PER the latest satellite imagery. Down stream of this feature, a broad shield of mid and high level cloud cover has streamed into western and north central Nebraska. Skies this afternoon were mostly cloudy to cloudy and temperatures as of 2 PM CT ranged from 8 degrees at Valentine to 19 degrees at Imperial. && .SHORT TERM /THROUGH TUESDAY NIGHT/... Issued at 312 PM CST Sun Nov 30 2025 The upper level disturbance, currently over northern Utah, will migrate east overnight, emerging onto the high plains of eastern Colorado and western Kansas by daybreak Monday. In advance of this feature, mid level frontogenesis will increase from eastern Colorado into northern Kansas and far southern Nebraska overnight. Light snow will develop INVOF this mid level lift later this evening, spreading east across northern Kansas and southern Nebraska into the overnight and early Monday morning. As for precipitation chances, not overly optimistic about snowfall north of Interstate 80. As for the threat for measurable snowfall > 0.1 inches, there is a 50 percent chance south of highway 92. When increasing this threshold to 1.0 inches, there is less than a 20 percent chance of hitting this amount south of Interstate 80. That being said, based on the ensemble NBM forecast, the deterministic NAM, GFS and EC solns appear overly "optimistic" about snowfall tonight. No doubt, given the mid level forcing, decent 1-3 inch accumulations look likely just off to the south of our forecast area, however, will plan on limiting accumulations to less than an inch, with possibly 1+ inches along far southern portions of the forecast area. This will be a fast moving system and the threat for snow will exit the forecast area by mid to late morning. In the wake of the exiting system, some clearing skies may facilitate highs reaching the freezing mark in the west Monday afternoon. Warmer air will then begin to push into the forecast area Monday night into Tuesday as the H5 pattern de-amplifies across the central CONUS. Lows will bottom out in the lower teens Monday night. This will be followed by middle 30s to middle 40s for highs Tuesday. && .LONG TERM /WEDNESDAY THROUGH SUNDAY/... Issued at 312 PM CST Sun Nov 30 2025 A northern stream disturbance will drop south from the northern Rockies onto the northern plains of the Dakotas Tuesday night. This will force a cold front through the forecast area. For the most part, this will be mainly a dry fropa with some limited forcing for precipitation noted well behind the front. This forcing is focused over South Dakota and far northwestern Nebraska, as well as along the front ranges of Wyoming and Colorado. The latest NBM snowfall probabilities have very limited probabilities of measurable snow across the forecast area with this system. Most probabilities are on the order of 20-30 percent for snowfall > 0.5 inches over the northwest Tuesday night into Wednesday morning. So far the latest NBM POP forecast has chances capped around 30 percent in the NW with this system and this seems reasonable given the low forecast QPF`s. This system will clear the forecast area later on Wednesday, however, temperatures will be cold with highs in the upper 20s to around the freezing mark. With expected clearing Wednesday night, lows will reach into the single digits. Temperatures will climb back into the 30s and lower 40s for Thursday, Friday and possibly Saturday depending on the timing of another arctic front. Temperatures will then fall back into the 20s and 30s for Sunday. Beyond Tuesday night, the next threat for light precipitation will arrive Saturday into Sunday. ATTM this appears to only produce minor impacts to the area. && .AVIATION /18Z TAFS THROUGH 18Z MONDAY/... Issued at 1121 AM CST Sun Nov 30 2025 For the KLBF terminal: Expect mainly cloudy skies over the next 24 hours. Ceilings will begin to slowly fall this evening bottoming out around 2000 FT AGL from 08z to 12z Monday. There will be a threat for light snow at the terminal beginning around 07z, ending around 14z Monday morning. Visibilities may reach as low as 2SM in light snow. Snow is expected to end after sunrise Monday morning with ceilings lifting to 5000 to 9000 FT AGL. For the KVTN terminal: Expect MVFR ceilings at the terminal this afternoon with ceilings ranging from 1200 to 2500 FT AGL. Ceilings will improve later this evening to around 8000 FT AGL. Expect some clearing of cloud cover Monday morning with a few high clouds ranging from 15000 to 20000 FT AGL. && .LBF WATCHES/WARNINGS/ADVISORIES...
