A few strong to severe thunderstorms will be possible, especially during the afternoon and evening. - Cooler weather is expected Sunday into early next week, with temperatures trending back up Tuesday into Wednesday. - Our next chance for rain appears to be on Wednesday with increasing uncertainty beyond this timeframe. && .DISCUSSION... Issued at 1056 PM CDT Fri Jun 12 2026 After a quiet Friday, thunderstorms return to the forecast early Saturday morning. These thunderstorms will be in response to moisture return on a low-level jet impinging on a slowly sagging cold front. Elevated showers and thunderstorms are expected to develop over portions of eastern Nebraska prior to sunrise. These thunderstorms will be in an environment that is forecast to have sufficient instability and shear for the development of large hail in the strongest cells. A damaging microburst can`t be entirely ruled out also. These thunderstorms gradually shift east of the area through the remainder of the morning hours. There is a bit of uncertainty on how the remainder of Saturday will transpire. Some of this evening`s guidance tends to keep at least some weak convection along the cold front into the early afternoon, accelerating it`s advance southward. Other guidance, has a lull in activity until later in the afternoon and evening, slowing the front`s advance. In either event, a digging trough over the northern Rockies tonight will sink towards our area by afternoon. This will act to support the development of additional thunderstorms along the cold front. At this time, most of this convection is forecast to remain south of Interstate 80. With plentiful instability and wind shear, a risk of severe weather is anticipated. Large hail and damaging winds will be the main threats, but an isolated tornado remains possible if a discrete cell can remain ahead of the front. In addition, flash flooding is possible with westerly upper-level flow supporting potential training of thunderstorms along the east-west oriented front. It should be noted, that if early day convection lingers, this could inhibit later convection, so we will have to closely monitor forecast trends. By evening, the cold front and any associated thunderstorms will push south and out of the region. A gusty north wind will fill in behind the front, ushering cooler temperatures. High pressure and cooler weather settles in on Sunday into early next week. Tuesday into Wednesday sees temperatures begin to climb once again as the pattern amplifies ahead of our next potential weather system on Wednesday. Wednesday afternoon and evening appears to be our next chance of rain for the area. After Wednesday`s system, forecast model guidance begins to diverge and significant uncertainty remains on the exact evolution of the forecast pattern in the extended forecast. && .AVIATION /12Z TAFS THROUGH 12Z SUNDAY/... Issued at 539 AM CDT Sat Jun 13 2026 KOFK: Thunderstorms are beginning to move into western Madison County and will be in the vicinity of the terminal at the start of the TAF period. Right now, the best chance for storms this morning will be through 15Z. There is a possibility of a second round of showers and isolated thunderstorms moving through the region between 19Z-22Z. Confidence in this secondary round of precipitation occurring is lower. With spotty shower/thunderstorm chances impacting the terminal in the possible second wave, the mention of this additional chance was omitted from prevailing conditions for the time being. Winds will become northerly today, increasing to around 12-18kts by 15Z. Winds become northwesterly overnight. KOMA: VFR conditions are currently ongoing, but thunderstorms are beginning to move in from the west. Right now, the best chance of morning convection will be between 14Z and 16Z or 17Z. A few storms will have the potential of producing some gusty winds and large hail. After the first wave moves through, the terminal can expect a break through mid-day, with a second round of storms developing in the afternoon. Models currently have storms developing over the Omaha Metro or slightly to the west around 22Z, with potential impacts through 01Z. Hail and wind appear to be the main concerns with any afternoon/evening storm development. Winds become northerly today behind a passing cold front, increasing to around 12-18kts. KLNK: Thunderstorms have developed this morning and are currently moving into the KEAR area. These storms will continue to track east, bringing them into the vicinity of KLNK later this morning. Right now, storms are expected to bring impacts to the terminal mainly between 13Z and 16Z, with hail and gusty winds being the main concerns. Once the first round of storms moves through, there will be a break through mid-afternoon before the second round of storms. Models are showing storm development over or just west of the terminal, with potential impacts between 21Z and 00Z. Hail and gusty winds are the main concerns for any afternoon/evening storms affecting KLNK. && .OAX WATCHES/WARNINGS/ADVISORIES... NE...None. IA...None. && $$ DISCUSSION...Chehak AVIATION...ANW

125 FXUS63 KGID 131130 AFDGID Area Forecast Discussion National Weather Service Hastings NE 630 AM CDT Sat Jun 13 2026 .KEY MESSAGES... - Scatter predawn thunderstorms in south central Nebraska could be marginal strong to severe with hail the main risk. Those clear the area by 8 AM. - Additional development of isolated thunderstorms is possible late this morning and afternoon as a cold front starts its advance. The chance for stronger storms is southeast of a Hebron to Osborne line, and for just a short period of time. - Next week starts slightly cooler than normal, then warms to above normal Wednesday before dropping back a bit late week. - Next week is looking more dry than wet with time. && .UPDATE... Issued at 126 AM CDT Sat Jun 13 2026 The early morning weather map showed low pressure in the southeast Colorado with a weak inverted trough to the north. A cold front, sort of temporarily stalled, was across the Nebraska Sandhills, while southeast/south winds where generally noted across south central Nebraska and north central Kansas. Surface dewpoints were increasing but the deeper moisture remains more tied to the storms in central/southwest Kansas. Satellite showed mainly clear skies in south central Nebraska with a canopy of thicker cirrus clouds from the thunderstorms across north central Kansas. Aloft, the forecast area is in a quicker flow between an advancing trough to the north and more sub-tropical flow the south. The result is a more zonal feel/look to the current upper flow. The main action for the weather is today, and mostly during the predawn hours to come. CAMS models have perked up with development of convection by 3 AM in south central Nebraska as the moisture and instability surge north on the south/southwesterly low-level jet. Those showers and storms quickly increase in coverage and intensity as they will move east/northeast, favoring areas of south central Nebraska north of Highway 6, and especially east of a Kearney to Ord line. SPC Marginal risk is worthy given decent mid-level instability and favorable shear, though we don`t have quite the low level moisture advection of two nights ago, nor are the mid-level lapse quite a steep. These storms will be elevated in nature and a classic overnight marginal to low end severe risk for a couple of hours at least. One negative could be the convection across southern/central Kansas acted to disrupt LLJ and moisture, which could lead to less organization in general. The southern part of the area (i.e. north central Kansas) seems the least likely area for storms early today, though we are seeing development already near the Kansas state line southwest of McCook. That is probably the beginning of tonight`s weather event. The models are pretty uniform in suggesting this morning convection will move east of the area between 7 AM and 9 AM, leaving a drier period for at least a few hours. The previously mentioned cold front will start to find some legs late this morning and works its way south across the area through the afternoon. Behind the front, expect a stiffer north wind to develop, and while it may be that much cooler than yesterday, it will be "cooling" with time. As the front advances, some lingering mid-level instability could result in a few showers or maybe a lightning strike, especially along/east of Highway 281. The front is expected to clear north central Kansas around 5-6 pm. It "could" spark a localized stronger storm for an hour or so southeast of a Hebron to Osborne line, but confidence is low in that scenario. SPC slight risk does include a sliver of Mitchell county though the clear better risk for severe weather is farther south and east. Winds will be up a bit this evening from the north but die off after sunset with drier air filtering south overnight. As skies clear, lows will well below normal, much like Friday morning, with some 40s again in the favored area. Sunday is the coolest day of the week with highs only middle 70s. Look for a mixture of clouds and sunshine, with more clouds south/west than north/east. The forecast is currently dry, but in the expected northwest flow, subtle waves can spring up a few afternoon sprinkles in the afternoon. The region remains under a more cyclonic flow through Tuesday. By Tuesday, we should return to near normal temperatures. Wednesday is likely the warmest day of the next 7 days with temperatures peaking ahead of an advanced front. Temperatures will slip back a bit later next week. There are sporadic, isolated rain chances Wednesday thorugh Friday, so can`t say for sure its dry, but its trending more dry than wet for sure next week. The next "best" shot for a more widespread rain/storm chance is likely Father`s Day weekend. && .DISCUSSION... Issued at 255 PM CDT Fri Jun 12 2026 Currently, a cold front has pushed into the Nebraska panhandle, and the local area is seeing fairly breezy south-southeasterly winds ahead of this feature. Dry conditions are expected to continue through the evening hours, but CAMs show a few thunderstorms developing after midnight tonight in response to the low-level jet. The overall severe threat remains limited thanks but there is enough instability/shear that we could see some elevated storms produce at least small hail. All that being said, the majority of the area is expected to remain dry through sunrise Saturday. On Saturday, the cold front is expected to continue to push through the area. As a result, northern areas are expected to be ~10 degrees cooler than today, but portions of northern Kansas will likely make another run into the upper 80s. By mid afternoon, CAMs show isolated to scattered storms developing near the front. This activity is expected to focus largely southeast of our area, but could clip our southeastern zones. Any storms that do manage to develop in our area could become strong to severe, thanks to MLCAPE values over 3000J/kg and 0-6km shear 30-40kt. Behind this cold front, noticably cooler air arrives for Sunday. Overnight low temperatures are favored to dip into the 40s for parts of the area Saturday and Sunday nights. High temperatures on Sunday are expected to only reach the low-mid 70s. A few light showers cannot be ruled out Sunday evening through Monday, but most areas will likely remain dry. A warming trend then takes for next week as ridging builds over the western/central CONUS. High temperatures are likely to reach 90s in most areas by Wednesday, and some areas could push 100 degrees. All-in-all precipitation chances look pretty meager through next week, with ensembles potentially hinting at a more active period again starting the following weekend. && .AVIATION /12Z TAFS THROUGH 12Z SUNDAY/... Issued at 625 AM CDT Sat Jun 13 2026 For KGRI/KEAR Airports: Morning showers and thunderstorms will move through both KGRI and KEAR, with KGRI more likely to experience a slightly more intense storm through mid-morning. Gusty winds with varying direction will impact both airports and TEMPO groups have been added to account. MVFR conditions have developed with the storms in the area. The precipitation will move on by mid/late morning, but another area of lower clouds and MVFR ceilings is likely to form along a cold front moving through. Along with the clouds, winds will shift to the north and gusts to 30kts into the early evening hours. Ceilings will lift by evening with VFR conditions and lighter winds overnight at both airports. && .GID WATCHES/WARNINGS/ADVISORIES... NE...None.
