- Moderate confidence in mild temperatures through this upcoming week

SHORT TERM /THROUGH TUESDAY/

Issued at 222 PM CDT Sun Jun 21 2026

The main concern in the short term will be thunderstorm chances both this afternoon and evening and again Monday afternoon and evening. As the trof advances eastward this afternoon will see thunderstorm development. Expect there to be two areas of thunderstorm development, the first will be thunderstorms that develop off the Black Hills and move southeastward into northern Nebraska, storm mode for this area will generally be clusters of supercells.

The secondary area of thunderstorm development will be across western Nebraska into the Panhandle. The environment across western Nebraska will be favorable for thunderstorm development in the warm sector as temperatures reach the 70s. Dew points will be in the low to mid 60s and MLCAPE values will be around 1500 to 2000 J/kg. This area has the better potential for strong to severe thunderstorms as it is located in the better environment. Storms across this area would generally expect to be discrete supercells, with hodographs suggesting the chance of splitting supercells as well. The main hazards with these storms will be large hail, with a secondary threat of damaging wind gusts. There is a low chance of a tornado threat, generally across portions of southern western Nebraska into the west central Sandhills. The threat for severe potential will generally subside by late evening, however there may be ongoing convection through midnight, but it is expected to remain below severe limits.

For Monday, Another round of strong to severe thunderstorms is expected in the afternoon and evening. A SW trof will move in from the west and will be the focus for thunderstorm development. With storms on Monday, the area of greatest threat for strong to severe thunderstorms is a narrow corridor, generally west of HWY 61 where the better environment will exist. MU CAPE values will generally be around 1000 to near 1500 J/kg, while east of HWY 61 CAPE values will only be around 500 J/kg or less. This area will also have shear values around 45 to 50 kts as well. The main hazards will once again be large hail and damaging wind, however at this time the setup is conditional with lower confidence in how much strong to severe thunderstorm development there will be.

AVIATION /18Z TAFS THROUGH 18Z MONDAY/

Issued at 1229 PM CDT Sun Jun 21 2026

Isolated storms will be possible early this afternoon across north central Nebraska, including KVTN terminal. Then additional isolated thunderstorms will develop across southwest Nebraska and could potentially impact KLBF terminal mid afternoon through early evening. Storms could have gusty, erratic winds, hail and brief heavy rainfall that could impact visibility. There will also be a chance for additional showers and thunderstorms late this evening into the overnight. Winds may be breezy across the northern Sandhills today around 10 kts with gusts up to 20 kts out of the east. Elsewhere, winds should remain light out of the east to northeast around 5 to 10 kts. Overnight winds will become light under 10 kts, at times, light and variable, then turn southeast Monday morning around 5 to 10 kts.

AVIATION /06Z TAFS THROUGH 06Z TUESDAY/

Issued at 1240 AM CDT Mon Jun 22 2026

Patchy fog will continue to impact portions of north central Nebraska through Monday morning. Fog will mainly be confined to the river valleys and low lying area and should diminish after sunrise. Ceilings remain below 3500 feet through early afternoon before rising to near 5000 feet by the late afternoon/early evening. Showers and thunderstorms are expected again by the evening, but will remain to the west of both terminals.
