KEY MESSAGES

- Continued warm and dry conditions are expected through the upcoming weekend.

- Deeper troughing will form over the western CONUS by early next week and should lead to a pattern change that includes cooler temperatures and modest precipitation potential.

SHORT TERM /THROUGH WEDNESDAY NIGHT/

Issued at 310 PM CDT Tue Oct 6 2026

This afternoon, sunny skies helped promote very warm temperatures across the area. As of ~3pm CDT, the North Platte Airport had hit 92F which sets a new record high for the day. This will likely become official with the climate reports tonight. Elsewhere, temperatures were generally in the middle 80s. These values were 15- 20F above normal for early October and were just another instance of the late summer-like heat seen in early October. Winds will light and variable across the area with speeds at or below 15 mph for all locations and many locations even reporting calm conditions.

For tonight...another quiet night is likely for much of the Central High Plains. Various high resolution guidance including HREF probabilistic data suggests another potential for valley fog affecting the Platte River system. Typically bullish guidance, notably the NAM12 solution, does not support this idea however so will keep mention out for now. With reinforcing dry air in the mid- levels and the expected light winds, believe temperatures will again fall in a good radiational cooling setup. Low temperatures lean heavily on MET/METBC guidance which supports middle 40s west to lower 50s east. Even these "cooler" values remain above climatological norms for early October, further adding to the mild start to the month.

Wednesday/Wednesday Night...modest high pressure will settle south across the Northern Plains. This will push a backdoor front into the area and introduce a slight cooldown in the area. Afternoon highs should only climb to the middle 70s to middle 80s range, warmest in the southwest. Light winds will again offset any concerning humidity minimums in the afternoon thus limiting fire concerns. There continues to be a slight wrinkle worth watching late Wednesday night. As high pressure continues to shift south into South Dakota, easterly flow will become established locally. This will increase convergence in an area of more southerly flow to the southwest. The NAM12 solution continues to suggest that within this area of convergence, scattered rain and thunderstorms will develop. The NAM12 appears to be the only promoter of this with other CAM and synoptic solutions showing little to no activity. The forecast remains dry for the time frame but PoPs continue to be in the 10-14% range or the highest values that allow a dry forecast. With the expected increasing clouds, whether precipitation related or not, milder temperatures appear possible though above normal values are still expected.

LONG TERM /THURSDAY THROUGH TUESDAY/

Issued at 310 PM CDT Tue Oct 6 2026

Low amplitude ridging will remain in place at the beginning of the mid-range period. With deep troughing over the Hudson Bay, a strong northern stream jet will stretch from the Canadian Rockies through the Great Lakes. Longwave troughing will eventually contribute to ridge breakdown Friday/Saturday, though mild temperatures will persist. NBM highlights fairly high confidence in continued anomalous warmth with inner-quartile ranges decreasing from 5F on Thursday to 2F by Friday and 4F for Saturday. This suggests a low variation in potential outcomes highlighted by NWP guidance thus the higher confidence. Though height falls will overspread the area this weekend as southwesterly flow becomes reestablished, precipitation prospects remain fairly poor through the weekend. This is because the aforementioned longwave will continue to dig south along the West Coast with a deep cutoff low taking shape by Sunday/Monday. This cutoff will then stall with shortwave ridging then building across the Central and Southerns Plains. The result will be warmer weather lingering a bit longer into the mid-range forecast. Precipitation probabilities continue to slowly trend down as upper- level dynamics largely miss the area to the northwest. This limits PoPs to around 30% or less, focused across the Sandhills up towards the Pine Ridge through Monday. Confidence for Monday and beyond remains quite low as evolution of the upper-level low is fairly uncertain. Deterministic solutions from the ECMWF/GFS both lift it north and east, crossing the Central Rockies sometime Wednesday/Thursday. While moisture should increase in the lead-up to arrival of this disturbance, ensembles paint fairly modest precipitable water values in the lead up to stronger synoptic lift. This may hinder precipitation efficiency and subsequently, amounts. EPS/GEFS probabilities are noisy though the majority (90% of members) show at least measurable rain around the middle of the week. Day-to-day predictability will likely remain poor until at least the upcoming weekend so continue to check with later forecasts for details.

AVIATION /18Z TAFS THROUGH 18Z WEDNESDAY/

Issued at 1225 PM CDT Tue Oct 6 2026

VFR conditions are expected through the forecast.

Winds will remain light at or below 10 knots through the bulk of the period. Towards daybreak Wednesday, increasing high level cloud cover should overspread the area. This will occur as winds favor a south to southeasterly direction with gusts in the 15 to 20 knot range.

LBF WATCHES/WARNINGS/ADVISORIES

None.
