DISCUSSION

Issued at 1209 PM CDT Tue May 26 2026

Weakening overnight convection continued to drift northeast of the forecast area this morning, leaving us with clearing skies and rising temperatures. By noon, most locations had reached the low 80s. Highs are expected to peak in the upper 80s and low 90s once again this afternoon.

A closed low pressure system will churn through the California coast through midweek. A lobe of low pressure/vorticity maximum will branch off of this disturbance, creating a boundary just south of the forecast area from northeastern Colorado through southern Missouri. High pressure will prevail to the north of the boundary, across southwest Iowa and into the Dakotas. This will likely keep our much needed precipitation shunted just southeast of the forecast area, through Wednesday and Thursday.

The west coast low will try to ebb eastward on Thursday into Friday, shifting the slightly northward, bringing a 20-30% chance for rain to far southeast Nebraska Friday.

The low will finally kick northeastward this weekend, but gradually weaken as it does so. Rain chances will overspread the forecast area ahead of the low, but remain in the 15-40% range, as models remain split on whether or not rain reaches us or stays on the fringes of the forecast area. The best chance for rain currently resides over southeast and east/central Nebraska, with a lesser chance (15-20%) over western Iowa. Overall, severe storm chances appear low at this time, due to weak instability, poor shear vectors, and meager upper level forcing. SPC and machine learning probs share a similar sentiment with a lack of outlooks highlighting the Central Plains over the next 7 days.

High temperatures look to remain above average, in the mid to upper 80s through Friday, but moderate into the low 80s for the weekend and beyond.
