Area forecast discussion, Jun 16, 5:56 PM MDT, 3 hours 45 minutes before
Area Forecast Discussion National Weather Service North Platte NE 656 PM CDT Tue Jun 16 2026 .KEY MESSAGES... - Fire weather concerns remain the main concern over the next 36 hours, with critical conditions likely Wednesday as wind gusts approach 40 to 50 mph and afternoon humidities fall to 15-25%. - After a cooler day on Thursday, temperatures rebound for Friday with some renewed fire weather concerns. - Unsettled weather arrives by the weekend with increased rain and thunderstorm potential including the threat for severe thunderstorms on Saturday. && .SHORT TERM /THROUGH WEDNESDAY NIGHT/... Issued at 259 PM CDT Tue Jun 16 2026 This afternoon, steady northwesterly flow continues across much of the Central CONUS. High level clouds continue to stream over the local area. Southwesterly flow continues and is helping push afternoon highs up across the area. Values as of early afternoon ranged from middle 70s in the northeast to middle 80s to the southwest. Winds were increasing out of the west and southwest with a few areas reporting gusts around 25 mph. Do anticipate these to increase slightly over the next few hours. This will lead to the much advertised critical fire weather conditions across the western Sandhills and Panhandle regions. Late this afternoon/tonight...westerly winds will continue to gust into the evening before backing to the south as a low-level jet develops. Our central Nebraska zones should sit beneath this strengthening speed max and this will result in mild overnight temperatures. Though values were decreased slightly, lows will still only reach the low to middle 60s or nearing 5-10F above normal. Surface winds will be strongest southeast of an Ainsworth to Imperial line. Have removed inherited PoPs across our northeast zones where forecast soundings show a reasonable saturated layer but ample dry air in the lowest 3km. This largely negates the potential for sprinkles even but will keep some 10-14% probabilities in the northeast though dry conditions likely wins out. Wednesday...a day of greater fire weather concerns with more pertinent details regarding this threat below in the Fire Weather Discussion. In the early morning, a frontal boundary will progress through western Nebraska with winds flipping to the north-northwest by daybreak. Beneath a belt of stronger mid-level flow from a passing trough to the northeast, gusts should ramp up markedly during the daytime. Probabilities for exceeding 40 mph gusts quickly increase from 30-40% around 7-8am CDT to 75%+ by 10am CDT. With strong flow aloft, climbing to 40+ knots at h7 for the bulk of the day, believe wind gusts will be strong through the whole day. Cold air advection and pressure rises will prolong gusts though the greatest magnitudes should be seen across the Sandhills into northern Nebraska. Further investigations into forecast soundings show largely unidirectional flow up through 2km with layer averaged winds of 25 to 35 knots. With the cold air advection, have been steadily trending afternoon highs down but feel we're beginning to settle into the precise range of temperatures so further decreases appear unlikely. The current forecast shows upper 70s in the north to near 90F in the south with gusts up to 50 mph along the NE/SD border decreasing to the 30-40 mph for areas south of the Platte Valley. Winds are largely expected to subside quickly in the evening, with the same HREF probabilities of exceeding 40 mph gusts falling to less than 10% for all areas outside north central Nebraska by early to mid evening. Overnight lows should settle closer to seasonable levels, settling in the upper 40s to middle 50s. && .LONG TERM /THURSDAY THROUGH TUESDAY/... Issued at 259 PM CDT Tue Jun 16 2026 Friday/Saturday...Fairly active weather appears set to return late week into early next week. Upper-level pattern will transition from northwesterly to more zonal and potentially more southwesterly. Shortwave ridging will arrive Friday but promptly begin to breakdown as an upper-level jet begins to nose into the California coast. Broad troughing will push into the Great Basin by early Saturday with a disturbance set to cross the Central Rockies. Developing surface low will lift a warm front north into southwest Nebraska with an influx of Gulf moisture across the southern half of the forecast area. While isolated activity is possible late in the day Friday, greater potential exists on Saturday with a more pronounced shortwave ejecting out of Wyoming. NBM probabilities highlight modest potential for rainfall Friday night with notable increases for Saturday: 50-70% probabilities for 0.25" east of Highway 83. While this is fairly broadbrushed at this time, it speaks to the environment that would support a fairly good coverage of rain and thunderstorms. With a mid-level speed max overspreading a moderately unstable warm sector in vicinity of a stalled frontal boundary, will need to be mindful of the potential for severe weather. The Storm Prediction Center has introduced a fairly rare June Day 5 outlook (the equivalent of a 15% Slight Risk) stretching from the Sandhills through southeast Nebraska. Have no qualms with that though placement of greatest threat may waver some in the coming days so folks are advised to keep up to date with the latest forecast. Sunday and beyond...active weather appears likely to continue into early next week though focus may shift east. Broad upper ridging will remain in place across Mexico and the Gulf and an upstream ridge beginning to amplify by Monday. Even as high pressure builds aloft upstream, persist moist flow up to the Front Range should support near daily rain thunderstorm chances with the question being how far off the higher terrain they reach. Extended ensemble guidance suggests greater QPF probabilities confined to areas west of Highway 83 as a result which bodes favorably for the areas dealing with the most significant drought conditions. Temperature spread within NBM solution is fairly low casting some confidence in the temperature forecast of near to slightly below seasonable norms with values reaching the upper 70s to lower 80s. && .AVIATION /00Z TAFS THROUGH 00Z THURSDAY/... Issued at 647 PM CDT Tue Jun 16 2026 VFR conditions will prevail over the next 24 hours. Winds will become lighter tonight, with LLWS overnight across portions of the southern Sandhills into southwest Nebraska including KLBF terminal with winds of 45 kts. Sfc winds will increase Wednesday early morning with the strongest winds by late morning through the afternoon. Winds will be out of the northwest around 20 to 25 kts sustained with gusts up to 45 kts. && .FIRE WEATHER... Issued at 259 PM CDT Tue Jun 16 2026 Critical fire weather conditions are expected Wednesday for much of western and central Nebraska, largely driven by very strong wind gusts with marginally low humidity. Wednesday...early morning frontal boundary will clear western Nebraska prior to dawn with gusts quickly increasing around and after sunrise. In closer proximity to main mid-level speed max, gusts should be strongest across and Sandhills through the NE/SD border where peak speeds should approach 50 mph. Confidence in this is fairly high with probabilistic guidance showing expansive 80%+ potential for exceeding 40 mph gusts but falling quickly to 20% or less for exceeding 50 mph gusts. Though temperatures have trended down in recent days, daytime highs will still be +/- 5F of mid-June climatological values. Dry air will infiltrate the area with isentropic analysis showing descending dry air likely to set up across the central Sandhills and south through southwest Nebraska. Some guidance suggests even some diurnal cumulus for our far north but warmer mid-level air above that will quell any vertical growth and preclude any lightning threat. Recent guidance from fuel contacts suggest green-up progresses for most of the area outside portions of Zone 204 but with the expected magnitude of gusts and abundance of dead fuels from the previous summer that fire will still carry. The Hot Dry and Windy index, based on GEFS data, shows 70%+ of its members advertising values surpassing the 75th percentile in its model climatology. Though critical humidity levels do not appear likely to be met outside of Zone 209, will continue to advertise critical conditions due to the strong winds. Winds do appear likely to subside quickly in the evening with probabilities dropping off substantially: from 60-80% at 4pm CDT to 10-30% only for far north central Nebraska by 7pm CDT. Though winds weaken, they likely will not go completely calm and as a result humidity recovery should be poor across the area. This is particularly true for the Panhandle through southwest Nebraska where maximum values should only hold into the 50-60% range. && .LBF WATCHES/WARNINGS/ADVISORIES... Red Flag Warning until 9 PM MDT this evening for NEZ204. Fire Weather Watch from Wednesday afternoon through Wednesday evening for NEZ204-206-208>210-219. && SHORT TERM...NMJ LONG TERM...NMJ AVIATION...Gomez FIRE WEATHER...NMJ
