DISCUSSION

Issued at 1102 PM CDT Tue May 5 2026

A reinforcing shortwave trough is sinking south over the northern Great Plains this evening. This feature within the broader longwave trough is helping to filter additional cool and dry air into the region. Rain chances should continue to move well south and east out of the region tonight. Surface high pressure builds into the area by morning, allowing for calm winds. Temperatures are likely to fall to near freezing across much of the area. That being said, lingering mid to high level clouds should limit frost development for most areas outside of areas near the South Dakota border. The cooler temperatures continue into Wednesday afternoon with another day of temperatures in the 50s across the area. On the bright side, cloud cover should gradually decrease with peaks of sun by the afternoon. Clear skies will allow temperatures to fall into the 30s once again Thursday morning, but an increasing southwest wind should keep frost at bay for most. Patchy fog in low-lying areas that are sheltered from the wind may still be possible.

Temperatures are forecast to warm through the end of the work week as modest upper-level ridging takes over. Temperatures rise into the lower 70s on Thursday before approaching 80 by Friday. It should be dry for much of the remainder of the work week, but a weak disturbance during the morning on Friday may be enough to squeeze out a low (10-30%) chance of showers. Our next good chance of rain doesn't take shape until the weekend. Saturday into Sunday sees an area of low pressure take shape south of the area as a shortwave trough moves out into the Great Plains. We are likely to be on the northern edge of the better moisture. That being said, shower and thunderstorm (30-60%) chances are anticipated for much of the area. The best chance of measurable precipitation will be across southeast Nebraska and southwest Iowa, closer to the developing low pressure system. A cool-down arrives behind this system on Sunday before temperatures begin to increase again early next week.
