KEY MESSAGES
- 30 to 50% chance for some scattered showers and storms along and south of a line from Lincoln to Nebraska City to Red Oak, IA after 6 pm. A few storms could be strong to severe.
- After a brief lull in activity Wednesday morning, widespread rain chances (80 to 90%) move into the area Wednesday evening into Thursday morning.
- Rain clears by Thursday evening with the rest of the week remaining dry. May see some areas of frost Friday night into Saturday morning.
LONG TERM /THURSDAY THROUGH MONDAY/
Rain will be ongoing Thursday morning as chances remain at 80 to 90%. Most locations will see totals of a half inch, while a few spots could see up to an inch, particularly across portions of northeast Nebraska. PWATs still appear to be on the higher end of climatology, with guidance ranging from 1 to 1.5 inches which is at or above the 90th percentile of KOAX sounding climatology for that date. Rain gradually comes to an end from west to east by Thursday evening as the H5 disturbance moves east and gets absorbed into a strong H5 wave that ejects from Saskatchewan/Manitoba into the Northern Plains.
Dry conditions are largely anticipated through at least Sunday as H5 ridging moves in. Expect a cool Friday with highs in the 50s before a warm up to the upper 60s and low 70s occurs for the weekend. Friday night into Saturday will see a strong sfc high move over most of the Plains region, resulting in clear skies and allowing us to cool to the low to mid 30s, so don't be surprised if you see some frost. Guidance suggests another potential wave approaching the area by late Sunday into Monday, but with this forecast update, the NBM suggests dry conditions remaining in place.
