A wintry mix of precipitation is possible in the Perry area Monday night, while in much of northern Iowa along U.S. Highway 30 and farther north a winter weather advisory is in effect from 6 p.m. Monday until Tuesday morning.
Along U.S. Highway 30, rain, snow and freezing rain are likely before 9 p.m., followed by snow. Temperatures will reach the low 20s tonight, with wind chill values as low as 10.
Wind will be blustery, with northeast winds at 17 to 20 mph and gusts as high as 28 mph.
The chance of precipitation is 90 percent. Little or no ice accumulation expected, but a total nighttime snow accumulation of 1 to 3 inches possible.
Tuesday morning will have a 20 percent chance of snow before 8 a.m. Clouds will give way to mostly sunny skies, and a high near 29 is predicted. Wind will continue blustery from the north at 10 to 17 mph, with gusts as high as 25 mph and a wind chill value as low as 10.
Farther north, 2 to 6 inches of snow is expected, with the highest amounts in the vicinity of the U.S. Highway 20 corridor east of U.S. Interstate 35.
Winds will be north to northeast overnight at 15 to 20 mph, producing some blowing snow along with the falling snow. Visibility could drop to one-half mile or less.
Roads in northern Iowa will become completely snow-covered and slick. Reduced visibility due to falling and blowing snow will also make travel difficult. Caution is advised.
