DISCUSSION

Issued at 158 PM CDT Tue Apr 28 2026

Radar this afternoon shows areas of showers moving across eastern Nebraska and western Iowa. Expect maybe a few hundredths of an inch of precipitation with these showers for those lucky enough to get anything. Despite the decent looking precipitation showing up on radar, we have had virga (rain evaporating before reaching the ground) in some locations today. This will limit some potential for accumulations.

Heading into tonight, a Frost Advisory has been issued for portions of eastern Nebraska. Low temperatures are expected to fall into the low to mid-30s overnight with winds under 5mph in many areas. Clouds are expected to decrease across the advisory area, becoming mostly clear. The main question with the frost potential tonight will be how quickly the clouds move out. Areas that hold onto cloud cover a little longer than expected may not receive any frost. Held off from putting fog into the forecast for now as cloud cover may limit some potential.

Wednesday, surface high pressure moves into the region bringing some slightly warmer temperatures. Expected highs will warm into the upper 50s to mid-60s with west winds approaching 5-10mph.

A cold front drops in from the north on Thursday, ushering in some slightly cooler air. Temperatures will range from the mid-50s to low 60s for areas along and north of I-80 with mid-60s for the I-80 corridor and locations south of it. There will be another chance for a few showers/storms along and ahead of the front Thursday afternoon. Areas of frost will be possible Thursday and Friday mornings.

Heading into the weekend, expect dry and warm conditions as a ridge shifts east, putting us under northwest flow. Expect a gradual warming trend with highs reaching the 70s by Sunday afternoon.
