Showers and thunderstorms continue across far southeast Nebraska and southwest Iowa late this evening. These showers and thunderstorms are ahead of a cold front that has been slowly moving east through the region. This front is expected to clear the area around midnight, bringing cooler and quieter weather behind it. Temperatures cool into the 40s across much of the area with any 50s confined to portions of southeast Nebraska and southwest Iowa Thursday morning. Light winds and clear skies may result in patchy shallow fog, but this threat remains low. Low-level moisture remains very shallow behind the front as cold, drier air filters in from the north. Temperatures warm into the 60s by Thursday afternoon with plentiful sunshine for a pleasant Fall day.

Our next weather system begins to approach the region heading into Friday. The previously mentioned cold front will stall just south of our area across the Central Plains. At the same time, a shortwave trough will lift northeast from the Southern Rockies into the Central Plains. Warm advection and isentropic ascent ahead of this feature helps to initiate thunderstorms late Thursday evening into early Friday morning. Any thunderstorms gradually spread north heading into Friday afternoon as the weather system continues to approach the area. Unfortunately, portions of northeast Nebraska may miss out on this rainfall. Temperatures on Friday remain similar to Thursday with the front remaining stalled to the south of the area and increasing cloud cover.

The aforementioned weather system begins to move east of the area heading into Saturday, Halloween. Rain chances taper off through the afternoon with the evening of Halloween appearing dry. This is welcomed news for anyone partaking in trick-or- treating. Temperatures remain in the 60s during Saturday afternoon, cooling into the upper 50s by evening. Sunday sees the return of quiet weather as we move into a lull between weather systems.

Weather early next week appears active. Model guidance is in relatively good agreement that a strong upper-level low pressure will take shape over the Central Plains on Monday heading into Tuesday. As this occurs, widespread rain chances are anticipated. At this time, our region remains along the center of the track of this system, thus keeping temperatures cooler with more of a steady rainfall. Rainfall could still be heavy at times with modified tropical moisture helping to feed this system. That being said, a more northerly track could bring warmer temperatures and thunderstorms into the forecast. There remains some uncertainty with the exact evolution of this system, so stay tuned as the finer details become clearer this weekend. In either event, cooler weather filters in behind this weather system by the middle of the week allowing 50s to return to the forecast.

VFR conditions expected through this evening before MVFR ceilings push in along with showers and potentially some isolated storms. No TS mention for now, given expected isolated nature, but there's a 20% chance for a brief storm at OMA and LNK, roughly in the 06-11Z window. Showers and storms look to linger into the day, but remain south of the TAF sites. Some DZ then looks to build at LNK late in the period, with associated IFR ceilings and MVFR visibility. Otherwise, expect winds to remain under 10 kts out of the east to southeast.
