The Boy Scouts' motto might apply to the weather forecast for the next few days and nights: Be prepared.
A cold front moving into eastern Nebraska and western Iowa tonight is expected to bring rain, winds and cooler conditions, said Bryon Miller, a meteorologist with the National Weather Service Office in Valley.
The Omaha area has a 60 percent chance of showers or thunderstorms overnight, with temperatures dropping into the mid-60s. Rain totals in some areas could reach .25 to .50 inches, Miller said.
The chance for more rain, and even severe weather in some locations, is at 50 percent for Thursday, beginning in the afternoon, he said. Highs should be in the upper 70s.
Temperatures are expected to begin their fall Friday night, Miller said, with a low in the lower 40s and a 40 percent chance for more rain.
Saturday “should be sharply colder,'' with a high in the 50s, he said. Winds of 20 to 30 mph — and gusts of 40 mph — will add to the chill.
Sunday will be a bit windy and a little warmer, with a high of 60.
In extreme northwest Nebraska, Chadron is expecting windy conditions and rain mixed with snow by Friday. As much as 3 inches of snow could accumulate, but any snowfall would melt quickly with warmer conditions projected for the weekend.
