HASTINGS, Neb. (KSNB) — The remnants of a morning thunderstorm complex have left scattered showers lingering across eastern Nebraska, keeping those areas a few degrees cooler, while western parts of the state have already pushed into the 90s. This pattern sets the stage for a blistering start to the week, with highs expected to climb into the 90s over the next several days. As the week progresses, a shift toward a more active weather pattern will bring multiple rain chances and significantly cooler temperatures.

Tonight and tomorrow, temperatures will remain mild, with lows in the 60s and some 70s across the southeast. An isolated shower or thunderstorm may develop into Monday morning, but most of the region will stay dry. Skies will turn from partly cloudy to mostly sunny by Monday afternoon, driving temperatures into the 90s. Areas along and south of the Nebraska-Kansas state line could approach triple digits. With dew points in the 60s and 70s, heat index values will likely reach the upper 90s to triple digits. Another round of isolated thunderstorms is possible Monday night into Tuesday morning, though the exact location remains uncertain.

Monday through Wednesday, temperatures will stay in the 90s to triple digits, with partly to mostly sunny skies and light winds. Heat index values will again climb near 100 degrees. Nightly isolated thunderstorm chances persist, and some storms Monday night could be strong, as a marginal risk for severe weather is in place. By Wednesday, a cold front will sweep through late in the day. Temperatures will still reach the 80s and 90s ahead of the front, but widespread shower and thunderstorm chances arrive Wednesday night. The forecast rainfall over the next week (maximum) suggests a wet turn.

Thursday into the weekend, on-and-off shower and thunderstorm chances will persist through the end of the workweek, keeping temperatures cooler in the 70s. This active and cool pattern is expected to continue through the weekend. There is considerable uncertainty regarding severe weather during this stretch, but it is not out of the question. As we head into the following week, temperatures will gradually warm back into the 80s, and rain chances will decrease.

Residents should stay alert for rapidly changing conditions, especially with the heat index early in the week and the potential for severe storms midweek. The dramatic shift from extreme heat to cool, rainy weather marks a noteworthy transition in the region’s early summer pattern.
