DISCUSSION

Issued at 1134 PM CDT Wed Apr 1 2026

The forecast period begins with a shortwave trough over northwestern Kansas expected to lift into eastern Nebraska by sunrise. Multiple rounds of showers will continue across the region overnight and into tomorrow morning. Heading into early Thursday morning, a surface low will move across the region with a warm front lifting out of eastern Kansas/western Missouri. With the multiple rounds of precipitation Wednesday and overnight, this could inhibit some of the potential for severe storms heading into Thursday morning. The main question as the front lifts north will be whether we have enough instability to allow for storms to develop and intensify to severe levels. For the later part of the morning, models are in fairly good agreement that the low center will cross over extreme southeastern Nebraska, with a cold front remaining over northern Kansas. With the current track of the low and front and limited instability, there is a non- zero chance that a couple of storms could become strong to severe over our southeastern portion of the CWA, but that chance is low.

Thursday's expected temperatures will range from the mid-40s along the Nebraska/South Dakota border to the mid-50s along the I-80 corridor. Highs reaching the 60s will be possible along the Nebraska/Kansas/Missouri/Iowa borders. Lows Friday morning will fall into the 30s and 40s.

Another low pressure system will move across the region on Friday, bringing additional chances for showers and thunderstorms. Depending on the track and timing of this system, a few strong to severe thunderstorms may be possible for areas along and east of a line from Beatrice to Omaha to Onawa, Iowa. There is still uncertainty between models in terms of timing and location of onset of storms as a dryline and cold front move through. Some models have showers/storms developing in central Nebraska, moving through the CWA during the morning with a broken line of storms forming across the southern part of the CWA late Friday morning. Others show the potential for a few showers north of the interstate in the morning, with thunderstorms developing toward Rulo, Falls City and just west of Clarinda, Iowa around late morning/early afternoon. Keep an eye on this system over the next 24 hours as things hopefully come into better alignment.

Colder air advects into the region Friday, with temperatures noticeably cooler Saturday morning. Expected lows will range from the mid-20s to the freezing mark along and north of a line from BEatrice to Tekamah. Precipitation should taper off for most areas before midnight. However, as temperatures fall across northern Nebraska, rain mixing with snow will be possible, changing over to all snow for a brief period of time. Snow accumulation at this time will be limited to a trace to maybe a dusting at most.

Drier conditions are expected over the weekend with temperatures returning to the mid-50s to mid-60s by Sunday.
