LINCOLN, Neb. (KOLN) - More warm and breezy weather is on tap for the day on Sunday to finish the weekend, though a cold front sweeping through the state will help temperatures cool back a few degrees by the afternoon with chances for thunderstorms into Sunday afternoon, Sunday evening, and Sunday night across the state.

Skies are expected to remain mainly clear through Saturday evening but with increasing cloudiness as we head into Sunday morning. Through the day on Sunday, we should see partly to mostly cloudy skies across the state with mainly dry weather through the morning hours. Into Sunday afternoon, a layer of warm air aloft should put a cap on any potential for showers and thunderstorms for Lincoln and eastern Nebraska, but as cold front begins to advance through the state, storms are expected to start developing across parts of western and southwestern Nebraska in the afternoon. Some isolated strong to severe storms will be possible along the front with large hail, damaging winds, and locally heavy rain as the primary threats. A marginal and slight risk for severe weather is in place across these areas from the Storm Prediction Center for the day on Sunday. Lincoln and eastern Nebraska are under a “General Thunderstorm” risk from the SPC.

Showers and t’storms are then forecast to continue to slide east across the state into Sunday night. By the time storms reach Lincoln and eastern Nebraska, severe storms aren’t expected, but the strongest storms could still produce strong winds and some small hail along with some locally heavy rain. Rain is then expected to hang around eastern Nebraska into Monday morning as we should see cloudy skies with cooler weather to start the week.

The Lincoln Marathon kicks off early Sunday morning and the weather should cooperate for all the runners and spectators, though it may be a bit on the warm side with temperatures in the low 60s early Sunday morning before reaching the mid to upper 70s by the early afternoon. Southwest winds likely remain a bit breezy and it may even be a bit humid at times with dew point temperatures forecast to climb up to near 60°.

Overnight lows across the state should remain mild thanks to the southwest winds and the increasing cloud cover. Look for lows in the mid 50s to low 60s across the coverage area, well above average for early May.

More mild temperatures are expected to start Sunday with lows in the mid 50s to low 60s.
