KEY MESSAGES

- Conditional threat for strong to severe storms (20 to 40% chance) expected today. If a storm can develop, it will likely become severe with all hazards possible.

- Showers and storms persist for Sunday, particular in far southeast Nebraska toward western Iowa (25 to 50% chance). A strong storm or two may occur (5% chance).

- Active pattern continues into next week with continued shower and storm chances. Some storms may be strong, particularly on Monday and Tuesday. Temperatures in the 70s and 80s persist before a slight cool down expected on Friday.

LONG TERM /MONDAY THROUGH FRIDAY/

The active pattern for showers and storms will continue into much of next week. For Monday, will see another H8 baroclinic zone lift northeast across the area with continued warm air advection helping push temperatures to the 80s areawide. A sfc low will track northeast through the area in tandem with a mid level wave which may help spark some showers and storms. However, the LLJ looks to point more toward the east, away from the forecast area. If a storm manages to form, it could become strong. NBM currently suggests only a 15 to 20% chance for some light PoPs along our northern and eastern border areas for Monday.

By Tuesday, should see a more potent H5 shortwave lift northeast from the Four Corners area into the Central and Northern Plains. Lee cyclogenesis ensues with the sfc cyclone tracking northeast throughout the day. Model guidance suggests the best instability and moisture pooling behind the front over our far eastern and southeastern service area. Coupled with strong deep-layer shear, should see another severe threat for the area (15% chance for areas east of a Lincoln to Omaha line). PoPs remain at 20 to 40% areawide Tuesday.

Model guidance stalls the shortwave a bit by Wednesday with lingering showers before finally lifting out of the area Thursday with brief ridging. Continued disturbances are progged to track through the area by late Thursday into Friday resulting in continued PoP chances of 20 to 40% by Friday. Temperatures Tuesday through Thursday remain warm in the 70s and 80s before a slight cool down to the 60s to low 70s arrives for Friday.
