KEY MESSAGES

- More storms may develop west of a Neligh to Wahoo to Nemaha line (20-40% chance) after midnight.

- Storms clear late Saturday morning leaving a pleasant day. - Periodic storm chances continue into next week.

NEXT WEEK

The busy pattern continues. To date, OAX has issued its fourth most t-storm warnings this year (PoR 1986).

Transient ridging ahead of a cutoff low traversing the Prairie provinces allows temps to climb a bit for Monday and Tuesday. That low's attendant cold front pushes through on Tuesday afternoon. This will bring another 40% chance of overnight thunderstorms thanks to the stalled front and isentropic upglide provided by the LLJ.

12Z global models suggest regular chance of precip and thunder through the work week as the area remains on the periphery of the southern high pressure dome. Looking for some change to hang your hopes on? All three deterministic global models develop zonal flow by next weekend.
