KEY MESSAGES

- Rainfall expected across a large part of the area tonight. A few strong to severe storms could occur, especially late this afternoon and evening. - More scattered areas of rainfall and storms continue Tuesday into Tuesday night. A few stronger storms will again be possible.

- Above average temperatures in the lower 80s and humid conditions Wednesday and Thursday with the potential for scattered thunderstorms. Gusty winds and heavy rain the main threat with any thunderstorms.

- Turning warmer and drier Friday through Sunday with highs 85 to 90.

SHORT TERM /THROUGH TUESDAY NIGHT/

Issued at 109 AM CDT Mon Jun 1 2026

Mid-level warm air advection is increasing across western and north central Nebraska early this morning. Some weak instability develops in the mid-levels and persists through at noontime today. Scattered showers and isolated thunderstorms are expected as a result of the mid-level WAA. The better forcing remains to the west of the area nearer the upper low located across the northern Rockies. Nevertheless, expecting some activity within the WAA regime.

Some uncertainty regarding the severe potential this afternoon. Not sure how much mid-level cloud cover will linger into the afternoon hours. HREF suggests the clouds should move off to the east of the area by shortly after noontime. This will allow for at least some surface based CAPE to develop across western into southwest Nebraska. Low-level upslope flow will increase by mid to late afternoon, with higher surface dew points (low to mid 50s) advecting westward. Scattered late afternoon convection should materialize across the western High Plains later this afternoon. A southeasterly low-level jet increases tonight, and most CAMs agree that a loosely organized MCS should materialize across western Nebraska and move eastward overnight. Shear is strong and high based supercells will likely be the mode as storms first develop later this afternoon. Multicell clusters will likely be the mode by tonight as many updrafts develop aided by the low-level jet. Large hail could occur at first late this afternoon, transitioning to more of a wind threat through the evening as the activity moves eastward.

Southwest flow aloft continues Tuesday as the upper low continues to linger across the northern Rockies. Forcing is decent and scattered showers and storms will likely develop during the afternoon into the evening hours. PWATS/low-level moisture continue to be more than adequate, and even though the overall shear decreases some, stronger storms will likely evolve off the higher terrain into western Nebraska Tuesday afternoon and especially by Tuesday evening.

LONG TERM /WEDNESDAY THROUGH SUNDAY/

Issued at 109 AM CDT Mon Jun 1 2026

Wednesday, an upper ridge will be centered over the Mid Mississippi Valley. An H5 disturbance in the southern stream located from northeast New Mexico into the Texas panhandle will lift northeast. Ample gulf moisture transported northward from the Southern High Plains into the Central Plains. PWATS as high as 1 inch northwest Sandhills to 1.4 inches southwest and east. Surface dewpoints could range as high as the upper 50s to near 65. As the disturbance in the Southern Plains lift northeast into southwest NE and the eastern Sandhills, it will interact with a northern stream trough moving across the Northern Plains Wednesday afternoon into Wednesday night. Chance to likely POPS Wednesday afternoon into Wednesday night. MUCAPEs reach 1000-2000 J/kg in the afternoon, while deep layer shear is fairly weak at 20 to 25 kts into Wednesday night. Gusty winds and heavy rainfall will be the main threats. WPC has a Marginal Risk for excessive rainfall for areas generally near and east of Highway 83.

Thursday the upper flow becomes nearly zonal. Still slight chance to low chance POPs during the afternoon and evening. Highs in the low 80s. On Friday, small chances for showers/storms as a weak Northern Plains trough focuses the better lift north and east of the area. Highs in the mid 80s.

Saturday and Sunday, warmer from 85 to 90 as upper ridging builds into the region, with mainly dry conditions.

AVIATION /06Z TAFS THROUGH 06Z TUESDAY/

Issued at 1239 AM CDT Mon Jun 1 2026

VFR conditions expected through 00Z Tuesday at the KLbf and KVTN terminals. Scattered will develop across the Nebraska panhandle and northeast Colorado late this afternoon and spread east across western Nebraska tonight. Have a prevailing P6SM -TSRA BKN070CB at KLBF 02Z-06Z. Lower visibility in heavy rain and gusty winds are possible. However, confidence too low to include attm.
