940 FXUS63 KLBF 251738 AFDLBF Area Forecast Discussion National Weather Service North Platte NE 1238 PM CDT Sat Jul 25 2026 .KEY MESSAGES... - A dangerous heat wave sets in today, lasting through Monday. Daytime highs in the upper 90s to lower 100s are expected, with lows in the upper 60s to lower 70s, providing little overnight relief. - Elevated to near critical fire weather conditions are possible this weekend, especially across western Nebraska due to a combination of hot, dry conditions and gusty winds. - Slightly cooler temperatures Tuesday through Friday, with isolated to scattered chances for thunderstorms daily && .SHORT TERM /THROUGH MONDAY NIGHT/... Issued at 203 AM CDT Sat Jul 25 2026 Upper level ridging is observed across the area, which will largely drive the weather today through Monday. A surge of warmer temperatures aloft is expected to begin in earnest this morning, supporting well above average temperatures across all of western and north central Nebraska this weekend into Monday. As such, heat headlines have been issued for the entire region, with more detail below. Before the heat begins in earnest, patchy fog is expected across portions of southwest and central Nebraska in the predawn hours and lingering a few hours after sunrise. Fog is expected to be most prevalent along area river valleys and lower lying regions, where better moisture pools overnight. However, expecting a fairly quick burn off as the sun rises and begins to burn off the fog. As the fog dissipates this morning, expecting a surge of warm air advection aloft, bringing anomalous 850 mb temperatures across the entire region. This will kick off well above seasonal temperatures this weekend, with dangerous heat expected through Monday evening. Today, the biggest change to the forecast has been the upgrade to an Extreme Heat Warning across portions of north central Nebraska. Under this Extreme Heat Warning, expecting that Heat Indices today and tomorrow will exceed 105 degrees, with Sunday being the warmest of the two days. Worth mentioning that the Extreme Heat Warning goes through Monday morning, as overnight lows are only expected to cool around 75 degrees, offering little overnight relief both nights. Outside of the warning area, a Heat Advisory is in effect, covering the rest of the region. Temperatures are expected to climb into the upper 90s to lower 100s, with heat index values generally around 100, but remaining under 105. Even though this area is "only" covered by an Advisory, worth pointing out that heat will still be stifling, and overnight lows still are only expected to cool into the low 70s offering little relief. Also worth mentioning that late afternoon to the evening, there is a chance for some isolated to scattered thunderstorm development across portions of western and northern Nebraska. However, forcing remains fairly weak and any storms are expected to be fairly high based. This should limit any severe concern, but also will limit any rain chances, as precipitation will be falling through a very dry low layer in the environment. Sunday looks to be the hottest of the next 3 days, with highs exceeding 100 degrees across the region. Along and west of Highway 61, heat index values between 101 to 104 are expected, which will actually be the "cooler" values during the afternoon. Along and east of the Highway 83 corridor and potentially including Lake McConaughy, the heat will feel quite oppressive, with heat index values climbing between 106 to 112 degrees. While this extreme level of heat would typically push into the Extreme Heat Warning level, guidance continues to suggest these heat index values are only widely achieved on Sunday, with low confidence in heat index values exceeding 105 on Monday. With that in mind, have kept the Heat Advisory as is. However, it is worth stressing that this will feel far hotter than last weekend`s Heat Advisory. Those sensitive to the heat and those with outdoor plans will need to take precautions, and should try to limit time out in the heat. Overnight will remain similar to tonight, with lows generally only cooling into the lower 70s, and again offering little relief. Now, with all the heat and fairly dry conditions across the region, this will bring concern for elevated to near critical fire weather concerns, especially along and west of Highway 61, where lowest humidity values are expected. Given the heat, expecting strong mixing across the region, which will support wind gusts of 25 to 20 mph. Additionally, though there are some chances for thunderstorms both nights this weekend, any storms that do develop ar expected to be very high based, with little chance of any precipitation making it to the surface. This may introduce a dry lightning threat. However, with minimal forcing, storm development is expected to be very isolated to scattered, and likely short lived. Still, the threat will exist, so will be keeping a very close eye on any potential developments. Monday, the heat continue through the afternoon, with highs climbing again into the upper 90s to lower 100s, and heat indices climbing again around 100 degrees. However, some relief may be on the horizon, as a cold front is expected to track through the region late afternoon into the evening. While this won`t bring a strong cool off, areas behind the front may see overnight lows dropping back into the 60s offering some cooler temperatures. This may also be the catalyst for showers and thunderstorms across the region. However, ensembles again remain fairly pessimistic, with the GEFS indicating a 20 to 30 percent chance of exceeding one tenth of an inch, and the European ensembles showing a 30 to 40 percent chance of the same. However, also worth mentioning that the European remains cooler, which may favor its higher precipitation chances. In regard to the Heat Advisory, though the front brings slightly cooler temperatures, it should be sufficient to push temperatures back below Advisory criteria, so have kept the Advisory through Monday evening. && .LONG TERM /TUESDAY THROUGH FRIDAY/... Issued at 203 AM CDT Sat Jul 25 2026 Upper level high pressure will remain situated across the southwest CONUS with ridging in place across the High Plains through the week. However, a series of disturbances will move along across the ridge, the first of which being a cold front late Monday night into Tuesday. This will bring reprieve to the extreme heat, although temperatures will still be quite warm with highs remaining in the low to mid 90s for Tuesday through Friday, at this time should remain below any heat headline criteria. There will also be chances for isolated to scattered thunderstorm chances Tuesday through Thursday as disturbances move along the ridge, but any organized thunderstorm development looks low at this time, so no widespread precipitation chance, but precipitation chances nonetheless. At this time severe weather potential is low, but will continue to monitor. As far as fire weather concerns in the long term, expect additional low level moisture around the area keeping min RH values around 30 percent or higher mid-week to the end of the week. && .AVIATION /18Z TAFS THROUGH 18Z SUNDAY/... Issued at 1240 PM CDT Sat Jul 25 2026 VFR conditions are expected to prevail through tomorrow afternoon across western and north central Nebraska. The exception to this would be with any thunderstorms this afternoon for terminals north of HWY 2. These storms would pose a risk of brief MVFR visibilities and gusty, erratic winds. Winds remain gusty from the south through this evening, with gusts as high as 20 to 30kts expected. Winds remain southerly overnight, at 10 to 20kts. && .LBF WATCHES/WARNINGS/ADVISORIES...
