727 FXUS63 KGID 120941 AFDGID Area Forecast Discussion National Weather Service Hastings NE 441 AM CDT Thu Jun 12 2025 .KEY MESSAGES... - Generally above normal temperatures anticipated through the forecast period with high temperatures running 5 to 10 degrees above normal each day. - Periodic (mainly small) thunderstorm chances anticipated across the local area. Chances will be focused mainly during the evening through overnight hours with at least a small chance for strong to severe thunderstorms most days. - A stronger upper level trough will likely bring the best chance for more widespread shower and thunderstorm activity next Tuesday PM or Wednesday, but still plenty of uncertainty with the timing and track of this trough. && .DISCUSSION... Issued at 344 AM CDT Thu Jun 12 2025 A few storms across the high plains late last night fizzled as they approached our western boundary, with only a few clouds pushing across the area early this morning. After a partly cloudy start to the day, expect another round of showers and thunderstorms to develop near the frontal boundary extending from south Dakota into western Nebraska by early evening...gradually weakening as they track east during the late evening and overnight hours. The HRRR brings these decaying storms to areas mainly west of Highway 183, with the NAM/NAMnest not nearly as optimistic holding these storms together as they track east. As a result, it was not surprising that the Marginal Risk for severe weather for today was trimmed and limited to areas to our west for this evening and overnight. A slightly better chance for severe weather returns to the local area Friday evening/night, as models have hinted at a more organized disturbance moving off the high plains and into parts of the local area. Correspondingly, the chances for severe weather have shifted east, but this is still a fairly low confidence event as the local area will be on the decaying edge of this system late Friday night. For the weekend and beyond, expect a messy ridge of high pressure to continue across the central plains with daily (mainly evening/overnight) chances for showers and thunderstorms along with continued above normal temperatures. Not all areas will see precip each day, and some areas may remain dry. The main difference this morning was the disappearance of the cooler temps next Tuesday, with highs now remaining in the lower 90s Tuesday afternoon, and the cooler day/more seasonable weather holding off until the upper level trough and better chances for rainfall return next Wednesday. While there is better agreement among the EC/GFS ensembles for a more widespread rainfall event next Tuesday PM/Wednesday, operational runs of both the EC/GFS still have significant differences, so overall confidence of timing remains on the lower side. So all is all, above normal temps forecast through the period with at least some chances for precip each evening/night (with the most promising chances likely next Tuesday PM/Wednesday). && .AVIATION /06Z TAFS THROUGH 06Z FRIDAY/... Issued at 1220 AM CDT Thu Jun 12 2025 For KGRI/KEAR Airports: VFR conditions expected through the period. A weak line of showers and thunderstorms west of the terminals early this morning are expected to further dissipate as they track east over the next few hours, with no more than a few mid/high clouds and possibly a couple of sprinkles by the time they reach the terminals. Southerly winds will remain steady near 10-12 KTS overnight as the pressure gradient will not relax much, with a very weak LLJ possibly resulting in very marginal LLWS (not mentioned). Winds will increase out of the south again during the daytime hours Thursday, with gusts to near 20 KTS...with a weakening disturbance moving off the high plains bringing additional cloud cover during the late evening hours Thursday. && .GID WATCHES/WARNINGS/ADVISORIES...
