DISCUSSION

Issued at 1205 PM CDT Mon Apr 27 2026

After an active period of weather last week and weekend, a much quieter weather pattern in taking shape for this week. A cold front moved across the region this morning, ushering in cooler temperatures. A few lingering showers and thunderstorms are quickly exiting the region to the east early this afternoon. Gusty northwest winds remain behind the cold front into this evening. Temperatures have already reached their highs for the day as temperatures are holding steady or falling behind the front.

Tuesday will start cold as 30s are likely for the area. There is a low (10-20%) chance of frost across portions of northeast Nebraska where temperatures fall to near-freezing. That said, lingering winds and relatively warm ground temperatures should keep frost at bay. Despite surface high pressure building across the Great Plains, a chance of showers returns by Tuesday afternoon as a mid-level disturbance moves overhead. While there is a medium (30-60%) chance for rain across the area, dry air near the surface will greatly limit what actually reaches the ground. Temperatures should be well below normal with highs in the 50s due to continued cloud cover and rain chances. Once again, temperatures fall into the 30s for most by Wednesday morning.

Temperatures return to near normal by Wednesday afternoon and Thursday afternoon with largely zonal mid-level flow taking shape over the region. Highs in the 60s with lows in the 30s and 40s are to be expected. There is at least a low (10-20%) chance of showers and perhaps a thunderstorm on Thursday with another passing mid-level disturbance. That said, limited moisture should limit what actually reaches the ground.

By the end of this week into this weekend, a warming trend begins. This is supported by a upper-level ridge building across the western third of the country. Temperatures climb into the 70s to near 80 through this period. Dry weather is anticipated at this time, with sunny skies forecast through this weekend.
