912 FXUS63 KGID 160543 AFDGID Area Forecast Discussion National Weather Service Hastings NE 1243 AM CDT Wed Sep 16 2026 .KEY MESSAGES... - Scattered shower/storm chances will continue on through the rest of tonight...with coverage potentially more isolated in nature during the daytime hours today. While it`s not out of the question some storms could be strong at times, the overall threat for severe weather remains on the lower side. - Additional storm chances later this evening/overnight tonight look to be mainly be focused across the SSErn half or so of the forecast area. Again, overall severe threat is low. Models showing an increased potential for fog late tonight...some showing dense fog not out of the question. - Continued southwesterly flow aloft through the end of the week keeps the pattern unsettled with periodic precipitation chances...with the main upper level low/trough axis looking to move through the Plains roughly in the Sat night-Sun time frame. Still lot of details to iron out, so overall confidence is on the low side. && .UPDATE... Issued at 1233 AM CDT Wed Sep 16 2026 Currently... Upper air and satellite data showing continued southwesterly flow in place across the Central Plains tonight...set up between an area of high pressure anchored over the southeastern CONUS, weakening/broad troughing over the Hudson Bay area, and another area of low pressure working its way south along the West Coast. Radar data showing isolated/scattered showers and storms impacting the area...driven by more subtle lower-mid level forcing. Models showing the better instability remaining focused along/south of our SSErn counties, though some elevated instability may work its way back north with time. Can`t rule out some stronger storms, but the overall threat for severe weather remains on the lower side...some small hail/gusty winds are possible, as is at times heavy rainfall rates. At the surface, the forecast area remains under the influence of an overall weaker pattern, with the main frontal boundary draped from the Great Lakes region southward through far SSErn KS toward the TX panhandle. This is keeping winds across the forecast area generally easterly and light, with speeds mainly under 10 MPH. Today and tonight... Not looking at significant changes through the immediate short term period. Models remain in good agreement showing little change with the southwesterly flow aloft over the region...the area of high pressure currently over the SErn CONUS shifts back west a touch, while the West Coast low continues to sink south. During the daytime hours today...hi-res models are in decent agreement showing precipitation chances being fairly spotty in nature. Upper level forcing looks to remain on the subtle side...and while it`s hard to have a ton of confidence in any place remaining completely dry all day long...it`s possible a decent chunk of the forecast area may end up that way. Expecting to continue to see plenty of cloud cover around, though more breaks in the clouds may start working their way in from the south and west as the day passes. At the surface, winds are expected to gradually turn more southerly with time, as sfc high pressure slides further east away from the region, while overall weak low pressure remains over the High Plains...keeping winds speeds on the lighter side, topping out around 10-15 MPH. Expecting a bit of a bump up in temps...after 60s-low 70s on Tuesday, highs for today are in the low-mid 70s. For precipitation chances this evening and tonight...models have trended toward the better focus being across the SSErn half of the forecast area. These chances are driven by again overall subtle mid-upper level forcing, and moreso by increased convergence along the nose of a SWrly low-level jet (around 30kts or so). Overall coverage looks to again be on the spotty side, gradually sliding east with time. Again can`t rule out some stronger storms, but the overall severe threat remains on the lower side. Another concern for later tomorrow night will be with the potential for fog...with models showing the potential for fairly widespread lowered visibilities, mainly across Neb. Will see how models trend today, but some models show the potential for this fog to be dense. Thursday and on... Overall, models haven`t changed a whole lot big picture-wise through the end of this week into the start of next week...keeping the pattern on the unsettled side. Upper level flow across the region remains generally southwesterly...showing high pressure shifting west further into the Srn Plains, while that West Coast low/troughing starts working its way further east. Periodic shortwave disturbance ejected out ahead of the main troughing will keep at least spotty precipitation chances in the forecast through the end of the week (mainly focused in the late ...with models showing the main system itself pushing east through the Plains roughly in the Sat night-Sunday time frame. Plenty of finer details to work out in the coming days...so confidence isn`t overly high the further out you go in time. As far as temperatures go...expecting warmer temperatures to end the work week, with Thursday in the upper 70s-near 90, and Friday having more mid 80s-low 90s. With the main upper troughing moving through during the weekend...cooler temps expected, with generally low-mid 70s by Sun-Mon. && .DISCUSSION... Issued at 149 PM CDT Tue Sep 15 2026 An upper trough is centered over the Pacific Northwest with an upper ridge centered over the southeast part of the country. South central and central Nebraska and north central Kansas are in between these 2 features. A surface high is across the area behind the cold front that moved through last night/early this morning. There is enhanced atmospheric lift along and just behind the cold front which has resulted in the development of some showers and thunderstorms across portions of the area. Severe storms are not expected with higher stability behind the front. Additional development of showers and storms is expected through the rest of the afternoon and again tonight. High temperatures today will generally range from the mid 60s to mid 70s. Low temperatures tonight will mostly be in the 50s with some lower 60s. The upper ridge expands further west over the southern Plains and portions of the central Plains on Wednesday. This will result in some portions of north central Kansas warming up into the low 80s. Otherwise, high temperatures will mainly be in the 70s. Showers and thunderstorms will again be possible (up to around 50% chance) on Wednesday as upper lift increases over the area from shortwave troughs moving overhead. Low temperatures Wednesday night will mainly be in the 60s with light, easterly winds. Chances of showers and storms continue through Wednesday night with chances up to around 70%. Temperatures are expected to warm up some on Thursday but the amount of warming is uncertain due to model differences in positioning of the upper ridge and surface boundaries. Temperatures will warm even further on Friday with a surface trough strengthening across much of the area. Various rain and storm chances continue Thursday and Friday as upper disturbances move over/near the area. Temperatures will cool beginning on Saturday with another cold front moving into the area. Also, an upper trough from the west will move towards and over the northern and central Plains through early next week displacing the upper ridge that was over/near the region. There is some uncertainty in temperatures during the weekend and early next week but most areas are expected to be in the 70s. Various rain and storm chances continue Saturday and Sunday with an increase in atmospheric lift due to the cold front and approaching upper trough. && .AVIATION /06Z TAFS THROUGH 06Z THURSDAY/... Issued at 1101 PM CDT Tue Sep 15 2026 For KGRI/KEAR Airports: Ceilings are slowly falling over central Nebraska and this will continue through sunrise. IFR ceilings are likely through Wednesday morning and into the afternoon before gradually improving. A few thunderstorms cannot be ruled out the potential for lightning in the EAR/GRI has decreased enough that the PROB30 TSRA has been removed. Winds remain light through the period, turning from the northeast to southeast. && .GID WATCHES/WARNINGS/ADVISORIES... NE...None. KS...None. && $$ UPDATE...ADP DISCUSSION...Schuldt AVIATION...Mangels
