Heavy rain is possible Monday night

A cold front that has produced heavy rain the past few nights to our north will move into our area Monday night. Storms that move through eastern Iowa Monday night may produce heavy rain, and the highest chance of that happening is near and north of Highway 30. One to two inches of rain is possible in the heavy rain risk area, and locally higher amounts would occur in places where storms move through repeatedly. If that happens, flash flooding would be a threat. If that happens, be especially careful if you’re driving during the night. Water over the road is difficult to see at night. If you come across a flooded road, don’t try to drive through it! Turn around and go another way.

How common are heat advisories in eastern Iowa?

As expected, with the incoming heat through the weekend, the National Weather Service issued a heat advisory for the entire area. Heat advisories in eastern Iowa are issued when heat indices are forecast to be near or in the 100 to 105 degree range. In fact, heat advisories are issued nearly every year. We usually see one to three heat advisories issued per season. The average first date of a heat advisory in our part of Iowa is around July 7. The average last issuance is August 10.

Beyond the Weather: The solstice is coming

As we progress past the mid-point of June, we’ll have to watch for a clear night. This time of the year can be a bit humid to take a look beyond the weather, but at least it’s cooler at night! The Moon, Venus and Mercury will be an interesting trio to watch Thursday night through Saturday. Park your lawn chair where you have an unobstructed view of the western horizon. About an hour after sunset, you can find the crescent moon. Mercury will be very near the horizon. The bright object to the upper left of Mercury is Venus. The moon will appear higher off the horizon each night through the weekend. The summer solstice is also approaching. This year it occurs on the June 21st at 5:07 AM. This marks the time that the sun is directly overhead on the Tropic of Cancer, the farthest north part of the sun’s journey in our sky. From then until later in December, the amount of daylight will shorten each day. Happy stargazing!

Nearly a full year of drought in southern Iowa

Through all the flash flooding, tornado warnings, and high wind of the past five days, one thing still stands strong: southern Iowa drought. Something that’s been observed over the years is the tendency for a pattern to become stuck, or persistent. Drought tends to breed more drought, and that is no doubt the case for areas south of Interstate 80. In fact, the better part of a year has been characterized by at least moderate drought over portions of far southern Iowa. Meanwhile, farther north, wet weather continues to be persistent. This part of the state is favored for the rain chance Thursday night into Friday. Little to none will fall south of Interstate 80, unfortunately.

Minor flooding on parts of the Cedar and Wapsi

Heavy rain over the weekend has a rise on both the Cedar and Wapsipinicon River moving downstream. However, only minor flooding at most is expected. The Cedar at Cedar Falls crested Monday night and is forecast to fall below flood stage midday Thursday. The Cedar at Waterloo crested Tuesday morning and is forecast to fall below flood stage Wednesday morning. The following forecasts are as of Tuesday afternoon and may change a little. The Cedar at Vinton is forecast to crest at 14.5 feet Wednesday morning, below the official flood stage of 15 feet. There are some small impacts even below flood stage. At 12.5 feet, water affects the lowest part of 22nd Avenue Road northwest of Vinton. At 10 feet, water affects low lying agricultural land north of Vinton. Water is flowing through the overflow channel north of the main channel on Highway 150. The Cedar at Cedar Rapids is forecast to rise above the flood stage of 12 feet Wednesday night and crest at 12.8 feet midday Thursday. At 13 feet, water affects the lowest residences in Cedar Bluff. At 11.5 feet, water affects Osborn Park in Cedar Rapids, and at 9.5 feet, water affects the lowest sections of Otis Road SE. The Cedar at Conesville is forecast to rise above flood stage of 13 feet Wednesday night and crest at 14.3 feet on Friday. 14.2 Water affects Lindle Avenue and Keokuk Avenue, both near Saulsbury Park. At 14 feet, water affects residences along County Road F70. At 13.5 feet, water affects yards and access roads of residences along Iowa Highway 22. Water affects the lowest sections of campgrounds just north of Interstate 80 along the river and the lowest sections of Jack Shuger Memorial Park in Moscow. Water is also on 152nd Street north of County Road F70. At 13 feet water affects Edgewater Road and 245th Street near Conesville, and at 12 feet, water affects low lying access roads to recreational properties along the river. The Wapsi at Anamosa is forecast to crest at the flood stage of 14.5 feet Wednesday morning. At 14.5 feet, Lead Mine Road is completely covered with water. At 14.2 feet, Lead Mine Road is closed. At 14 feet, water affects Lou Lou's Landing campground near Olin. The Upper Iowa, Turkey, Volga, and Maquoketa already crested and are back below flood stage. The Iowa, English, Skunk, and Mississippi will not experience any flooding from the recent rain.
