836 FXUS63 KOAX 040526 AFDOAX Area Forecast Discussion National Weather Service Omaha/Valley NE 1226 AM CDT Sat Jul 4 2026 .KEY MESSAGES... - Scattered thunderstorms continue through the early morning hours, with one or two strong storms producing hail or damaging winds. - Independence Day will feature highs in the 80s to lower 90s. There is a 30% chance for thunderstorms during the evening, and if they develop, they could produce locally damaging winds. - Sunday through much of Tuesday brings a period of slightly cooler, slightly drier, and mainly precipitation free conditions. && .DISCUSSION... Issued at 1123 PM CDT Fri Jul 3 2026 Several severe storms developed this evening, but the overall intensity of those storms has waned as we`ve gotten into the evening hours. As of midnight, we do have some fresh development on the nose of a weak low level jet from the Grand Island area over toward Wahoo. This environment has a substantial amount of most unstable CAPE, in the 3000 J/kg range, but the effective shear is not particularly impressive and forecast soundings show a bit of a weak cap for those elevated parcel sources. Going forward, anticipate this scattered thunderstorm activity to continue particularly between Lincoln and Columbus and areas to the southwest. There is a small chance for one or two of the strongest storms to produce severe hail, but it seems it would require a particularly tall updraft to access better effective shear, and might be favored in any left-moving elevated supercell that can develop given the anticyclonically curved effective hodograph. By 2 or 3 AM, these storms should be on a decreasing trend as the weak LLJ further weakens and refocuses farther south. Independence Day will be warm and humid with highs in the upper 80s to low 90s, and dewpoints up around 70 again. Much of the day is likely to be free of precipitation, but there is a feature of interest currently crossing central Montana in WV imagery scheduled to approach our northwestern parts of the forecast area by early evening. Several (but definitely not all) models are producing scattered thunderstorms in advance of this short wave trough. Boundary layer convergence is weak and unimpressive with this system, but the mid/upper support may be sufficient to set off storms. If thunderstorms develop in SD and northern NE, there is a decent signal that they could push a cold pool southeast across the forecast area and force additional development. Expect moderate instability in place with unimpressive wind fields, so a widespread organized storm complex doesn`t look especially likely, but will still need to monitor the potential for damaging wind gusts. And of course, any potential for thunderstorms during the evening of the 4th can have substantial impacts. Right now I`d say we`re looking at about a 30% chance of a thunderstorm influencing peak fireworks hours, and mainly southeast of Albion, Norfolk, and Wayne areas. Sunday and Monday are likely to be quieter with mainly dry conditions and temperatures in the 80s with a slightly drier airmass. Tuesday will be similar, but late in the day could see storm chances return especially in the north as a short wave trough crosses the northern Plains. There is strong model agreement that the front associated with that trough will sag through our area on Wednesday with a good chance for thunderstorms. Then our next best chance for storms arrives Friday night with another stronger short wave trough. && .AVIATION /00Z TAFS THROUGH 00Z SUNDAY/... Issued at 642 PM CDT Fri Jul 3 2026 Thunderstorms continue to redevelop over the southern half of the area this evening. Expect chances of showers and storms to fade overnight, mostly from west to east. Have -TSRA for the next hour at KOMA and the next two at KLNK, but confidence in that timing is low and more development may mean amended TAFs soon. Have also added some lower cigs and reduced visibility around sunrise. Have LIFR conditions forecast at KOFK from 4am to 10am. That`s pretty pessimistic, but it`s close to expectations. After the fog lifts, conditions will quickly return to VFR and normalcy with light northerly winds. && .OAX WATCHES/WARNINGS/ADVISORIES... NE...None.

707 FXUS63 KGID 040624 AFDGID Area Forecast Discussion National Weather Service Hastings NE 124 AM CDT Sat Jul 4 2026 .KEY MESSAGES... - Most of the daytime will be dry this Independence Day. - Isolated to scattered showers/storms return from the north/northwest this evening. Some could be marginally severe. - The early part of next week should remain mostly dry. && .UPDATE... Issued at 123 AM CDT Sat Jul 4 2026 As of 1am, more robust convection continues to redevelop over northwest Kansas and eastern Colorado. This activity is expected to push eastward through the early morning. This is expected to primarily impact areas near and south of the KS/NE state line, but isolated storms cannot be ruled out further north as well. Hail will be the primary threat with these storms, although locally damaging wind cannot be ruled out either. Near-term models show this activity weakening and departing the area by around 8-9am at the latest, and the rest of the daytime should remain dry. This afternoon, the strongest thunderstorms should redevelop safely to our southeast, but additional storms are also anticipated to develop over the Sandhills and gradually move southeastward through the evening hours. There isn`t great consensus amongst the CAMs on coverage/timing, but I would anticipate at least a few storms to contend with for fireworks displays this evening. Shear is a bit weaker than today, but would still be supportive of at least a couple "low-end" severe storms. After today, the forecast dries out as we head into next week. It will remain warm, but not excessively hot. Off and on rain/t-storm chances return in days 4-7 (Tuesday night through Friday). Temperatures are favored to remain near to slightly above normal during this period, but longer-range ensembles are hinting at the potential for extreme heat returning for next weekend and into the early part of the following week (July 11-14). && .DISCUSSION... Issued at 230 PM CDT Fri Jul 3 2026 I have focused on the nearest 24-48 hours and thus the majority of this discussion will focus on that period. This evening and overnight hours has multiple rounds of thunderstorm activity, I will go into the expectations of each one. Round 1: This evening 5 PM - 11 PM This area is what we are watching now, primarily development is expected along the Hwy 30/Platte River Corridor between Grand Island and Columbus, NE. Between 1 PM and 2 PM cloud cover, cumulus has grown in areal extent. The vertical nature of this cumulus is still relatively shallow, but the area shows where there is more instability. This area southward along Highway 81 will be will be the favored area for development between 5-7 PM. This activity could be severe and is highlighted by the SPC enhanced risk, and expect a convective watch at some point in time. Severe winds to 70 mph, hail to the size of golf balls are the primary threats. A tornado cannot be ruled out, and flooding, especially for areas that receive multiple later rounds is a threat. This activity is expected to track south and east into eastern/southeastern Nebraska and into northeastern Kansas as we move towards sunset and beyond. Round 2: Tonight midnight - 4 AM Thunderstorms are expected to develop along the nose of the Low Level Jet with thunderstorms developing along an east-west line following roughly Interstate 80. There is some question exactly where this activity will develop, but anywhere along and south of I-80 is in the region for being impacted by these thunderstorms. Some of this activity could be severe. This activity is expected to track southeast with time. Meanwhile Round 3 will be starting off.... Round 3: Tonight 3 AM - Saturday mid-morning Thunderstorms are expected to develop across the High Plains of northwestern Kansas and southwestern Nebraska and track slowly east during the overnight and early morning hours. This activity is expected to be similar to what we saw this morning, with weak showers/thunderstorms. Severe storms are not anticipated. How will these storms impact Saturday July 4th? All of these rounds of thunderstorms today will impact how the chance for thunderstorms develops Saturday. The morning thunderstorms will push the potential for afternoon/evening thunderstorms southward into central and southern/eastern Kansas. While we cannot rule out some of the afternoon storms impacting Rooks, Mitchell, and Osborne counties, as of this forecast it`s looking optimistic. For the areas that are impacted by Round 3, once it stops raining and clears out, it is expected to be a dry and sunny day. For everyone else, it looks to be a dry and sunny day. Thunderstorms are expected to develop across the High Plains of the Nebraska Panhandle, and they are expected to track southeast with time, similar to the track seen last week. This could impact north central Kansas counties in the late evening and early overnight hours. Overall the picture for tomorrow for north central Kansas will become more clear tomorrow morning after all of these rounds of thunderstorms. Highs on the 4th are currently forecasted to be in the upper 80s to low 90s. After the 4th... The end of the weekend and start of the work-week look dry as upper level ridging begins to build in from the southwest. It doesn`t last overly long as some stronger disturbances break the ridge down and precipitation chances return for the second half of the work week. Temperatures will generally be seasonal with highs in the upper 80s to low 90s. && .AVIATION /06Z TAFS THROUGH 06Z SUNDAY/... Issued at 1148 PM CDT Fri Jul 3 2026 For KGRI/KEAR Airports: Low ceilings may develop overnight until around 12z but confidence is too low to include at this time. Generally expect storms to stay away from the terminals overnight but there remains about a 20% chance an isolated storm will impact the terminals. There is an even higher chance of storms from around 01z to 04z Sunday. Winds will mostly be variable and light (mostly below 12 knots). && .GID WATCHES/WARNINGS/ADVISORIES... NE...None.
