731 FXUS63 KGID 200007 AFDGID Area Forecast Discussion National Weather Service Hastings NE 607 PM CST Wed Nov 19 2025 .KEY MESSAGES... - Patchy fog expected to return tonight...some of which could be locally dense again Thursday morning. - Rain chances return Thursday night as rain lifts north into the area. This band of precipitation has trended further north, and areas along and south of I-80 now expected to see some modest rainfall amounts. Highest totals will be across Kansas (up to 1"), with possibly little to no accumulation north of Highway 92 (T-0.01"). - Pleasant weather this weekend with highs in the 60s, light breezes (mostly less than 10 MPH), and sunny skies. - Changes coming next week as a more active and eventually colder weather pattern overtakes the region. && .DISCUSSION... Issued at 238 PM CST Wed Nov 19 2025 Fog was a little more widespread and thick across the area this morning than previously anticipated. By late morning, most locations were fog free and partly sunny skies (with lots of high level cloud cover) returned to the region. For tonight...expect another potential round of fog to develop across the local area after midnight, as light winds along with at least partial clearing are anticipated across the region. While some models like the HRRR are indicating the fog will be more widespread to start the day on Thursday, confidence is not overly high as while the winds are light they also look to have a westerly (downslope and less favorable) component. As a result, included the potential for patchy dense fog both in the forecast as well as in the HWO, but opted against a headline this early as it may end up being more patchy than some models suggest. Will need to play this by ear and see how things end up developing this evening/early night to see if a dense fog advisory once again becomes necessary. Otherwise, after at least a bit of fog to start the day on Thursday, the focus will turn to the upper level low currently circulating near the eastern California/southern Nevada border. While we have had our eyes on this system for several days, models are now swinging this area of low pressure further north towards the local area by Thursday evening as an upper level trough moves across the Great Lakes Region. This means the main band of precip should set up a bit further north, and areas along and south of I-80 are now favored to see some measurable rainfall. While there still will be a tight gradient in the band of precip that develops, confidence is increasing that the tri- cities could receive between 0.25-0.50" (about a 50% chance). The good news is that this system is relatively warm, and any precip locally should fall as rain through Friday afternoon. With the clouds and rain, however, Friday will likely remain on the cooler side, with some locations likely not climbing out of the 40s. After a cool/unsettled end to the week, a beautiful weekend continues to appear on tap for the local area. Behind Fridays exiting upper level low, ridging aloft is anticipated over the weekend as the next upper level low across the desert southwest slowly rounds the base of the longwave trough. As heights rise, so should temperatures, with mostly sunny skies and above normal temperatures expected both days. As a bonus, with a weak pressure gradient under the upper level ridge, surface winds should also be light, with afternoon breezes likely less than 10 MPH. As with the first system Tomorrow night/Friday, the trajectory of the subsequent upper level low early next week has trended further north in both the operational runs of the GFS/EC. Therefore, while official pops with this system are on the low side (10-30%), they may ultimately be too low as the vast majority of the EC ensemble members are indicating measurable precipitation along with about 50% of the members of the GFS. Again, given the origin of this system, the chance of any snow early next week looks low. Beyond this system, however, the upper level ridge breaks down, and much cooler air and an active weather pattern in progressive northwest flow returns to the area Thanksgiving eve and beyond. Still too early to predict the first measurable snow, but things are looking more promising towards the end of next week. && .AVIATION /00Z TAFS THROUGH 00Z FRIDAY/... Issued at 558 PM CST Wed Nov 19 2025 For KGRI/KEAR Airports: Potentially complex and impactful next 12-18 hours due to low CIGs and/or VSBYs. Expect decreasing high clouds and winds this evening. The weakening winds and clearing skies could set the stage for some fog develop around/after midnight - though the exact extent/coverage and severity remains uncertain. Seems quite plausible at least MVFR VSBYs will develop late overnight, and it`s possible they could fall to IFR levels. Some of the latest model guidance seems to keep the worst of this fog just S of the terminals - but am hesitant to buy into this solution fully at this time. Separate from the fog development potential after midnight will be a southward moving deck of LIFR/IFR CIGs and at least MVFR to IFR VSBYs along and behind a weak cold front. Uncertain if this will be low CIGs and VSBYs OR primarily low CIGs...but either way, IFR to LIFR conditions appear likely in the 13Z to 16Z or 17Z time frame before some improvement for the afternoon. Winds will transition from light and variable overnight to N to NE behind the front Thu AM at 6-10kt. Overall confidence is Medium. && .GID WATCHES/WARNINGS/ADVISORIES... NE...None.
