KEY MESSAGES

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

- Windy conditions on Saturday 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 1037 PM CDT Wed Oct 7 2026

Scattered high clouds across the area this evening. The upper- level pattern shows broad ridging over the western third of the CONUS with broad troughing over the eastern two-thirds. Overnight tonight, high clouds should make it more difficult for fog to form, but we could still see patchy fog in low-lying areas and river valleys develop, burning off after sunrise. Thursday we're looking at another quiet day with temperatures in the upper 70s to low 80s for the afternoon.

A weak developing low over the Nebraska Panhandle will bring a warm front through eastern Nebraska Thursday night into early Friday. 00Z CAMs show a line of showers/storms developing along that warm front near the Missouri River Valley of northeast Nebraska into western Iowa. Soundings show sufficient elevated instability, but low-level dry air will make it difficult for any precip to reach the ground. Good enough for a 20-30 percent chance of showers/storms though.

Increased warm-air advection on Friday will bring temperatures back up into the mid 80s. With recent trends for the NBM being a bit low, we could potentially approach records which are 88 for Friday and 91 for Saturday at Omaha (90 Friday and 91 Saturday for Lincoln).

Saturday we see a deepening low pressure system crossing south- central Canada push into the strong ridge over the Great Lakes region, steepening the pressure gradient across the Northern Plains down to our area. This will really ramp up winds across our area with winds gusting 35-45 mph expected, strongest over northeast Nebraska. These winds will be sourcing air from the drier areas of New Mexico, west Texas and western Kansas. Dry, windy conditions over the drier parts of central and northeastern Nebraska may create fire weather concerns Saturday afternoon. This pattern breaks down Saturday night into Sunday as the Low in Canada breaks down as it gets forced overtop the Ridge.

Looking west toward the latter half of the weekend we see a deep trough slide down the West Coast setting up a fairly active southwesterly flow pattern going into next week. Ridging pushing up out of Mexico into Texas will serve to intensify the upper- level jet spanning from southern California northeast into Nebraska and South Dakota. This baroclinic pattern decreases confidence in the fine details of the forecast for next week, but ensemble guidance generally show a cold front bringing temperatures back down Monday with precip chances returning Tuesday or Wednesday. This pattern is prime for a prototypical Fall-like severe weather event somewhere across the Great Plains later next week as the deep low over southern California gets reabsorbed back into the upper-level flow moving in Thursday or Friday. Much cooler air moves in behind it. Certainly a time period to watch.

VFR conditions are favored through the forecast period. Patchy fog is underway this morning, generally in river valleys and low- lying areas. However, the probability of impacts at the terminals remains low (10% chance). Otherwise, winds will be calm and variable early this morning, gradually pulling to south- southeasterly into the afternoon. Winds will remain light through the period, though a few 12-14 kt gusts will be possible this afternoon. Mid- and high- level cloud cover will increase through the period.
