KEY MESSAGES

- The chance of fog, possibly dense, returns to the forecast tonight into tomorrow morning and again tomorrow night into Monday morning, primarly for areas south of Highway 30.

- Dry and sunny fall weather is expected through the next week, with highs generally in the 60s through Wednesday and lows in the 30s to 40s.

DISCUSSION

Issued at 117 PM CST Sat Nov 7 2026

Broad, upper-level decent behind a passing shortwave trough has allowed clear skies and dry conditions to develop over the area this morning. These clear skies, along with weak westerly winds around 5-10 MPH, will allow highs to climb into the 60s this afternoon. These clear skies will be interrupted by an upper-level cloud band moving over the area this evening through tonight. Despite the temporary increase in cloud cover, temperatures are expected to fall into the upper 30s to low 40s by tomorrow morning. These cool temperatures along with light winds gradually becoming more northerly promote the development of fog tonight into tomorrow morning, particularly south of Interstate 80 in low-lying areas. The latest 2 REFS ensemble runs (6Z and 12Z) both show a 20-40% chance of seeing visibilities dropping below 1 mile by tomorrow morning.

As the upper-level trough continues to progress eastward, a small ridge is expected to build into the area Sunday through Monday. This ridge will help promote the persisting dry conditions, clear skies, and high temperatures increasing into the mid 60s Sunday and Tuesday afternoons and into the mid to upper 60s Monday afternoon. Light northerly winds Sunday morning will gradually become southerly throughout the day, with speeds remaining around 5-10 MPH.

The chance of fog returns tomorrow night into Monday morning, as light winds and clear skies allow lows to fall into the low 40s. Recent model guidance currently indicates a 40-70% of seeing visibilities falling below 1 mile by Monday at 8AM, particularly for areas south of Highway 30.

Overall, model guidance is in agreement that a shortwave trough will pass over the area Tuesday evening into Wednesday, causing surface pressure to fall across the area. This strengthening pressure gradient will cause the surface wind speeds to increase, with gusts of 30-35 MPH possible Wednesday. Despite this wave moving overhead, the chance of precipitation remains minimal (up to a 5% chance Wednesday).

As a larger scale trough, with embedded shortwaves, develops across the northeast and a ridge develops over the western CONUS, greater uncertainty enters the forecast, as models disagree on the location and magnitude of this large-scale wave. For example, current ECMWF guidance shifts this trough more to the east, allowing warmer temperatures to develop across the Plains towards the end of next week. On the contrary, the GFS has this trough shifted more to the west, keeping cooler temperatures and windy conditions in the forecast longer. This disagreement has lead to current NBM guidance showing a spread of 15 degrees between the 75th to 25th percentile Friday afternoon, with a spread of 10 degrees entering the area as early as Thursday morning.
