KEY MESSAGES

- Dry conditions for most of this week with a 20-30% chance of showers for northeast Nebraska/western Iowa Thursday night- Friday.

- Windy conditions return for Saturday and may lead to fire weather concerns in northeast Nebraska.

- More widespread rain chances arrive toward the middle of next week, but details on exact timing still need to be worked out.

DISCUSSION

Issued at 215 PM CDT Wed Oct 7 2026

Very quiet across the region today with surface high pressure building in and leading to plenty of sunshine. Despite northerly winds, temperatures as of 2 PM were in the mid 70s to mid 80s. For tonight, a few pieces of guidance hint at some fog development. We look to have a decently deep light wind layer, though speeds aloft start to pick up toward 4 AM, so think any fog that does develop will be pretty patchy and confined to river valleys and low- lying areas.

At least the daytime hours on Thursday look quiet, though a surface low will be spinning up east of the Rockies, helping to drag a warm front into northeast NE/west-central IA by the afternoon. Strengthening warm air advection and some weak moisture transport pointing toward the front suggest we'll have at least some low end precip chances north of the boundary (20-30%). That said, most CAMs offer relatively dry solutions, keeping things spotty or not developing any precip at all (at least through 7 AM). Model soundings (even models that have precip) also show a fair amount of dry air to overcome and a general struggle to saturate. Therefore, tend to agree with most CAMs that things will be pretty spotty and light in our area.

Attention then turns to strengthening winds Friday into the weekend as the surface pressure gradient tightens ahead of a surface low moving across MT and into the Dakotas. Saturday looks like the windiest day with model soundings showing 40+ kts at the top of the mixed layer, especially over northeast NE. As it stands, forecasting 35-45 mph gusts across much of the area. Also dropped dewpoints a bit based on guidance tending be too high as of late. This results in RH values dipping into the lower to mid 30s in parts of the area. As a result, we may end up with some fire weather concerns, though fuels outside of northeast NE generally remain wet and/or green. The main concern would likely be in agricultural fields as harvest begins. Practice good fire safety!

Upper level ridging builds in Sunday ahead of a cold front sliding in from the north. There will be a decent amount of precip associated with some shortwave energy rounding the ridge, but guidance is in pretty good agreement that it remains to our north.

Heading into next week, there remains a decent amount of spread in exact timing of how things pan out, but the general idea is that a cutoff low sets up over southern CA while a tropical system moves into the Gulf of California. Some guidance hints that some of that tropical moisture makes its way toward NE and IA once again, though still lots of spread in how far west or east it is, as well as when associated precip would happen. Currently, chances really start to increase Tuesday night into Wednesday, but still lots of details to work out. Given the spread in precip timing, the temperature forecast is also fairly low confidence. That said, highs in the 80s this weekend should fall at least a decent amount once the front passes through Sunday, with 60s and/or 70s expected into next week.

AVIATION /00Z TAFS THROUGH 00Z FRIDAY/

Issued at 536 PM CDT Wed Oct 7 2026

VFR conditions expected to persist through the TAF period with passing high clouds. Winds will be light overnight, shifting to southeasterly Wednesday morning. A few models suggest potential for fog development in low-lying areas and river valleys around 10-13Z, but chances for impacts to the terminals remain below 20 percent. Winds will be increasing out of the south-southeast to 6-10 kt by the afternoon.
