Eastern Nebraska is heading into an extended period of increasingly hot weather, with forecasters expecting limited opportunities for meaningful rainfall through much of the next two weeks.
7-10-26 NWS
The National Weather Service in Omaha/Valley says a hot and dry pattern will begin Saturday and dominate much of next week as a strong ridge of high pressure builds over the central and northern Plains. Temperatures are expected to rise from the upper 80s and lower 90s this weekend into the mid and upper 90s by Wednesday and Thursday.
In Lincoln, forecast heat-index values climb into the lower 90s this weekend and early next week before reaching approximately 94 degrees Wednesday and 96 degrees Thursday. The highest apparent temperatures across the region are expected during the middle and latter portions of next week, with some communities approaching a heat index of 100 degrees.
The Weather Service says Lincoln and Omaha could experience greater impacts because buildings, pavement and other urban surfaces retain heat and cool more slowly than surrounding rural areas. The agency’s HeatRisk outlook places Lincoln generally within the moderate-risk category Wednesday and Thursday, meaning the heat could affect people who are particularly sensitive, especially those without adequate cooling or hydration.
Far northeast Nebraska and portions of western Iowa could reach the major HeatRisk category, where conditions may affect anyone without sufficient access to cooling and water.
The heat does not appear likely to break quickly.
The Climate Prediction Center’s six-to-10-day outlook, covering July 15 through July 19, strongly favors above-normal temperatures across Nebraska. The outlook also favors below-normal precipitation across much of the central and northern Plains.
That pattern remains largely intact in the eight-to-14-day outlook covering July 17 through July 23. Nebraska continues to lean toward above-normal temperatures, while the region is forecast to have near- to below-normal precipitation probabilities.
A below-normal precipitation outlook does not mean the area will receive no rain. Isolated thunderstorms could still develop, but the broader atmospheric pattern reduces the likelihood of widespread or frequent rainfall.
The combination of persistent heat, high evaporation rates and limited rainfall could begin drying lawns, gardens and agricultural soils, particularly in locations that miss scattered thunderstorms. The impacts would become more significant if the pattern continues beyond the current two-week outlook.
No heat advisory or excessive heat warning was in effect early Friday, but forecasters said the likelihood of heat-related illness will increase as heat-index values climb.
Residents are advised to drink plenty of water, take frequent breaks from outdoor work and move strenuous activities to the morning or evening when possible. People should also check on older adults, neighbors without air conditioning and anyone especially vulnerable to heat.
Forecast temperatures and rain chances will become more precise as the hottest period approaches.
