KEY MESSAGES

- Warm and dry conditions remain probable (90%+ probability of no measurable rain) through at least Wednesday.

- Outside of a low-end chance for rain late Wednesday across north central Nebraska, precipitation potential appears limited until a pattern change arrives sometime next weekend.

SHORT TERM /THROUGH MONDAY NIGHT/

Issued at 318 PM CDT Sun Oct 4 2026

This afternoon, surface high pressure continues to drift southeast across the central and eastern parts of the state. Southerly winds were increasing on the backside of this feature with gusts in the 20 to 25 mph range for areas along and west of Highway 61. Further east, winds remained light at or below 15 mph. Temperatures continued to climb with upper 60s over north central Nebraska increasing to low to middle 70s south and west. Only another few degrees should be added to any one location for peak highs this afternoon.

Tonight...high pressure will continue to depart the area as lee troughing increases across the Front Range. This will increase the pressure gradient and lead to steady winds through the overnight hours. Moisture fetch will also increase with upstream observations showing low to middle 50s dew points. Deterministic solutions carry this plume of richer low-level moisture into western Nebraska and combined with the persistent winds, should allow for much milder lows. Temperatures should fall into the upper 40s to middle 50s, warmest outside the sheltered areas where winds may be more gusty. This is especially true for the Pine Ridge east along the Niobrara Valley.

Monday/Monday Night...troughing will continue to deepen across the central and northern Plains through the early part of the day. The resulting compressed pressure gradient will support gusty south- southwest winds through much of the day, peaking late morning into the early afternoon. NBM 30+ knot probabilities highlight a fairly transient jet max with peak wind gusts translating west to east through the day, peaking around 50-80% for portions of the central Sandhills into much of north central Nebraska. Raw RAP/HRRR output agrees with this, showing stronger south-southwest flow peaking 15- 18z (10am-1pm CDT) along Highway 83 then focusing east to the east by mid-afternoon with slight decreases. In the vicinity of a surface trough, winds will likely remain below 15 mph. Within the general westerly flow behind this feature, downsloping winds will promote warmer and drier conditions. While above normal temperatures are likely for all of central and western Nebraska during the afternoon, warmer values climbing into the middle to upper 80s appear probable behind this trough. The drier air will foster humidity values falling below 25% west of Highway 61 and potentially fall to the 10- 15% range closer to Highway 385 and points west. Though these values will constitute critical humidity, the stronger winds remaining well east of the lowest humidity preclude greater concerns. The surface trough should work back west in the evening allowing humidity to once again fill in to the west. With a resumption of steady winds, mild overnight lows are expected again with upper 40s to lower 50s.

LONG TERM /TUESDAY THROUGH SUNDAY/

Issued at 318 PM CDT Sun Oct 4 2026

Dry conditions remains likely through the first half of the upcoming week. Upper ridging across the western CONUS should flatten some with general northwesterly flow persisting. Moisture will remain bottled up along the Gulf Coast with westerly low-level flow within a dry airmass supporting above normal temperatures. Daily max temperature values at both KLBF and KVTN appear set to exceed the 75th percentile values in each site's respective climatology for Max and Min temperatures. Confidence remains high in dry conditions through the middle of the week for most locations.

A new wrinkle in the coming forecast is a frontal boundary expected to move into the area around the late Wednesday/Thursday timeframe. A northern stream disturbance should drag another cool front south into the area. While this is unlikely to support a noteworthy airmass change, the boundary should stall in the area with increasing kinematics into the evening supporting rain and thunderstorm potential. Deterministic solutions differ on timing and placement thus this remains somewhat low confidence, however, recent ensemble guidance shows increasing QPF probabilities for central and eastern Nebraska. Output from the NAM, GFS, and ECWMF all paint at least light QPF but differ on placement, timing, and magnitudes. For now, have maintained a dry forecast with newly introduced PoPs focused over Knox/Cedar Counties immediately to our east. Greater support for rainfall chances and cooler temperatures should arrive this weekend as a much more formidable trough dives southeast across the Pacific Northwest. Southwesterly flow prior to arrival of this upper-level disturbance will allow for greater moisture quality to establish itself and should support increased rain potential. An introduction of cooler air from the northwest bears watching for its potential to introduce our first shot at wintry weather but for now this appears likely to remain over western South Dakota. Temperatures should fall through the weekend into the following week but to what magnitude remains unclear as NBM temperature spreads remain quite large.

AVIATION /12Z TAFS THROUGH 12Z MONDAY/

Issued at 1156 AM CDT Sun Oct 4 2026

VFR conditions are expected through the forecast period.

The main aviation concern will be developing LLWS tonight transitioning to gusty south winds through the late morning. Have inserted a mention at both LBF and VTN beginning early Monday morning as winds ramp up quickly off the surface. This should persist for a few hours before developing into gusty winds at the surface with peak speeds around 25 to 30 knots.

LBF WATCHES/WARNINGS/ADVISORIES

None.
