UPDATE

Issued at 1231 AM CDT Thu Aug 20 2026

Currently there are storms in western Kansas which are moving to the southeast. These storms are not expected to move into the forecast area but additional storms may develop later overnight (around 4 or 5 AM) across western portions of the forecast area. These storms are not expected to be severe. Patchy fog is expected to develop later overnight across the area with the most likely area being along and east of Highway 281. Some of this fog may become dense (50% to 70% chance). There is uncertainty if there will be widespread dense fog. Conditions will be monitored for possible issuance of a Dense Fog Advisory. Low temperatures overnight will be in the upper 50s to mid 60s.

Any fog that develops overnight is expected to clear up by late morning. Southerly winds will be present today with temperatures warming up into the low 80s to low/mid 90s. Storms may develop this afternoon (to the north and west of the forecast area) and move into northern portions of the area by late afternoon/early evening. These storms may then continue to move southward through the evening hours. Some of these storms may become strong to severe with large hail and damaging wind gusts. Additional storms may develop late tonight into Friday morning after sunrise across portions of south central Nebraska. There is uncertainty whether the storms Friday morning will be strong to severe but the potential is there (around 30% chance). Additional storms (possibly strong to severe) may develop Friday night across portions of the area.

DISCUSSION

Issued at 303 PM CDT Wed Aug 19 2026

A cluster of showers and thunderstorms impacted much of the northeastern portions of the area from the morning through early afternoon hours. These storms produced small hail and severe wind gusts at times, and eventually exited to the southeast by mid-afternoon. The outflow from this activity currently resides near the NE/KS state line, and could see some additional thunderstorm development near or just south of this boundary this evening in response an approaching upper level disturbance. If realized, a strong to marginally elevated severe storm will be possible, and a marginal risk for severe weather remains in effect for the local area tonight.

After midnight, as skies remain or become mostly clear, winds remain light, and high dewpoints remain in place, expect the potential for patchy to widespread fog development across the local area. SREF probs indicate there is about an 80 percent chance of fog development (below 3 miles) with the last couple of runs of the HRRR now indicating at least some patchy dense fog development. As a result, introduced areas of fog to the forecast with the mention of some patchy fog below 1 mile to the HWO this afternoon.

Thereafter...a generally active northwestelry flow pattern with multiple disturbances is forecast to impact the local area through the extended periods. This should result in multiple chances for thunderstorms continuing, and a marginal to slight risk for severe weather is in place for the local area both Thursday and Friday evenings/nights. The upper level ridge to our west may then nudge across the area over the upcoming weekend, bringing slightly less favorable thunderstorm chances Saturday and Sunday, with predominantly more northwestelry flow returning next week. Overall, this looks like a fairly active weather pattern with seasonable temperatures continuing and a modest warm up possible late in the period.
