572 FXUS63 KLBF 090921 AFDLBF Area Forecast Discussion National Weather Service North Platte NE 421 AM CDT Wed Jul 9 2025 .KEY MESSAGES... - A threat for a few strong or severe thunderstorms are possible this afternoon into the evening. - A somewhat better threat for scattered strong to severe storms exists Thursday afternoon and evening. - Cooler temperatures are expected Friday into Saturday behind a cold front. - Warmer Sunday through Tuesday with a few thunderstorms possible early next week. && .SHORT TERM /THROUGH THURSDAY/... Issued at 418 AM CDT Wed Jul 9 2025 A weak shortwave disturbance will approach the western Nebraska by mid to late this afternoon. Winds aloft increase some compared to yesterday, with continued moist low-level southeast flow at the surface. With the slight increase in winds aloft, overall shear looks better somewhat better for storm organization, with further support from the weak disturbance approaching the area. Appears initial isolated storm development will be within favorable upslope low-level flow regime across northwest Nebraska along/just ahead of a surface trough. A well mixed, hot, boundary layer will exist where initial storm develop occurs. The airmass downstream will be quite unstable due to the hot temperatures, dew points in the 60s, and steep mid-level lapse rates. CAMS vary on the amount of storm coverage, which does not lead to a high-confidence forecast in terms of location and just how many storms there will be. The HRRR seems to be the most bullish, with initial storm develop across northwest Nebraska mid to late afternoon. As storms move eastward late this afternoon through the favorable environment...would expect at least storms to become scattered as they cross the Sandhills/north central into portions of southwest Nebraska. With the hot, well mixed boundary layer, gusty, possibly severe outflow wind gusts appear to be the main concern. Scattered storms/broken line with a continued gusty wind threat will move across central Nebraska early this evening before exiting the area mid to late evening. The upper level ridging begins to flatten Thursday with a stronger wave emerging from the Rockies into the area Thursday afternoon and Thursday night. A cold front will be associated with this wave and will be the focus for more widespread thunderstorm development. The cold front should be entering eastern Wyoming into northern Colorado by mid to late afternoon. Storms will first focus along this boundary across the higher terrain to the west of the area. Storms should increase in coverage as they move into western Nebraska by late afternoon. The airmass across central into western Nebraska will be quite moist, warm and very unstable. Damaging winds appear to be the main threat, with secondary concern being large hail. An isolated tornado cannot be ruled out, especially by early evening when east-southeast low-level flow is expected to increase across western/central Nebraska. An MCS could emerge by mid evening as storms track eastward through central Nebraska. && .LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/... Issued at 418 AM CDT Wed Jul 9 2025 Cooler weather is expected in a post-frontal environment Friday into Saturday. Scattered showery weather looks possible Friday with mid- level FGEN developing as cooler air aloft filters into the area. This weakens by Saturday with rain chances decreasing/ending. As mentioned it will be cooler, with highs Friday only forecast to reach the lower 70s across portions of northwest Nebraska. Most areas should be around 80F on Saturday. Upper level ridging then begins to nose northeastward across the desert southwest Sunday through Tuesday...with a return to highs in the mid 80s to lower 90s. A few thunderstorms will be possible early next week with any weak disturbances that are embedded within the flow in the mid/upper flow on the northern periphery of the upper ridging. && .AVIATION /06Z TAFS THROUGH 06Z THURSDAY/... Issued at 1244 AM CDT Wed Jul 9 2025 Isolated showers and thunderstorms are expected to develop early this morning across portions of north central Nebraska. At this time, any storms are expected to remain south of KVTN and northeast of KLBF with minimal impacts to both terminals. Otherwise, VFR conditions remain in effect through Wednesday afternoon. Some increasing clouds and lowering ceilings are anticipated by Wednesday afternoon, however, ceilings remain above 10 kft through the evening. && .LBF WATCHES/WARNINGS/ADVISORIES... None. && $$ SHORT TERM...Taylor LONG TERM...Taylor AVIATION...Kulik
