Early afternoon analysis showed a narrow, pesky band of low clouds stretching across much of eastern NE into far southwest IA with surface ridging/high pressure in control. It will continue to erode from both the east and west, though thinking we'll start to see low clouds re-develop once the sun sets. The areas that are able to clear out may see some fog development overnight with light southwest winds helping to usher in a tiny bit of moisture while temperatures quickly fall. However, there are some mid to high level clouds streaming in from the west that could limit fog coverage. So overall confidence in fog coverage is somewhat low, but it does seem favorable to have some in at least parts of the area. In fact, it seems like a Dense Fog Advisory may be needed in some locations overnight into Saturday morning, just not sure on exact locations yet. With the expected fog and lingering low clouds, forecast lows have ticked up a bit and now remain above just freezing in many places. That said, it'll be close, so you'll probably want to disconnect any garden hoses you're still using and be alert for some patchy slick spots, especially on bridges and overpasses.

The surface high will push off to the southeast by Saturday morning with southwesterly flow starting to usher in warmer air. Currently expecting highs in the mid 50s to lower 60s with guidance in decent agreement that clouds should start to erode through the day. However, but given how pesky clouds have been the last couple days, may end up staying a touch cloudier than previously thought, which may keep us a few degrees cooler. Regardless, the southwesterly flow should allow us to warm at least a little bit compared to today.

The warming trend continues Sunday into Monday with highs topping out in the mid 60s to lower 70s on Monday as upper level ridging edges eastward toward the area. A cold front is then progged to slide though Monday night into Tuesday, though not expecting too much of a dip in temperatures, especially by November standards, as highs remain in the upper 50s to mid 60s through the remainder of the week. Despite the frontal passage the forecast remains dry with guidance showing quite a bit of low level dry air remaining in place. A few various ensemble members suggest a weak shortwave trough could slide through sometime Tuesday night into Wednesday, though consensus keeps this wave and associated light rain well to our north. Toward the end of next week, a large scale trough looks to dig into the eastern CONUS, while it looks like we'll be on the western periphery and remain under northwest flow, guidance does hint at some light spotty precip potentially clipping us, depending how far west the trough extends. Chances remain below 10% though. Otherwise, the trough could bring our next chance at a freeze on Friday, though the air coming down from Canada doesn't look to be particularly cold at this time.

AVIATION /00Z TAFS THROUGH 00Z SUNDAY/

KOFK: Expect MVFR to IFR conditions this evening into tonight at the terminal. Stratus will be in place across eastern Nebraska, possibly spreading west toward KOFK. Fog is expected to develop after 05Z with potential visibility reductions to IFR levels.

KOMA/KLNK: Stratus will persist over the region this evening, with MVFR to IFR conditions expected. Fog is expected to develop across northern Nebraska south to KJYR overnight. With the stratus in place, potential fog development will be limited to areas west of the terminals; however, there remains some concern that clouds may break up a bit which could open the door to some patchy fog development a little further east than currently forecast. Have maintained the stratus in prevailing conditions for now.
