KEY MESSAGES

- Highs reach the 80s today with a small chance (15-20%) for some showers and storms this afternoon.

- 50-70% chance for some showers and storms overnight, with the highest chances across northeast Nebraska. Storms may be strong to severe with gusty winds and small hail.

- Active pattern continues Thursday and Friday with chances for showers and storms. A few storms may be strong to severe both days.

- Brief lull in storm chances Saturday before resuming Sunday (30-60%) and Monday (40-60%). Temperatures remain warm in the upper 80s with a few low 90s by Tuesday.

LONG TERM /FRIDAY THROUGH TUESDAY/

Early Friday morning, some long range CAMs like the NAMNest suggest the MCS feature lingering across the area til around 11z. Repeated passage of storms over areas that received a lot of rainfall Thursday afternoon could see localized instances of flash flooding. Later in the day, should see another H5 shortwave trof track through the area while a sfc cold front approaches from the west. Instability will pool in the warm sector ahead of the main front, ranging from 2,000 to 3,000 J/kg of CAPE, and combined with steep H7- H5 lapse rates and 0-6km bulk shear around 30 kts, some threat for severe storms will exist. Various machine learning algorithms suggest some threat for strong to severe storms for the area, so if you have any plans for Friday, make sure to stay up to date with the forecast. PoPs remain at 30 to 50% for Friday afternoon, increasing to 60 to 80% Friday evening.

For Saturday, the H5 ridge builds into the Northern Plains. Expanding 1000-500 mb thicknesses should yield warmer temperatures, with most areas reaching the upper 80s to low 90s. Large scale subsidence should help limit Saturday's storm chances, with any chances largely confined over our far southeast areas. More chances for showers and storms return Sunday (30 to 60%) and Monday (40 to 60%) as a wave lifts northeast from the Southern Plains toward the Central Plains. With this forecast update, the various machine learning algorithms indicate severe potential remaining to our south and west. Temps remain in the mid to upper 80s both days. Primarily dry conditions are favored for Tuesday as another H5 ridge builds into the Northern Plains.

AVIATION /12Z TAFS THROUGH 12Z THURSDAY/

Issued at 538 AM CDT Wed Jun 3 2026

VFR conditions are expected to prevail throughout the forecast period. Winds will remain calm and out of the southeast early this morning before becoming more southerly and increasing to 12-15 kts with gusts up to 22 kts by this afternoon. Mid- and high-level clouds will increase in coverage through the day, with a few clouds around FL050 passing by through the late morning and afternoon.

A cluster of thunderstorms is expected to push in from the west after 04/04Z, with the highest confidence in impacts at KOFK. Confidence is lower (30% chance) in thunderstorms making it to KLNK and KOMA.
