Beyond the Weather: Planetary finds

Clearing in the sky is in the forecast for this weekend, just in time for some views that go beyond the weather. Through this weekend, a few planets are easy to find. Look to the southwest at nightfall and locate the moon. The moon will be the highest off the horizon. To the lower right, the next brightest object will be Jupiter, with Venus lowest near the ground. Saturn is another fun planet to look at, especially using a telescope to distinguish its rings. The moon appears closer to Saturn each night this weekend in the southern sky. Next week, the waxing gibbous moon nears the planet Mars at dusk. Turn to the southeast sky for this view. Happy stargazing!

Moderate drought creeps northward

This week's Drought Monitor, released Thursday morning, shows that moderate drought has expanded slightly since last week. The moderate drought region, colored in peach, now extends from Washington up to near the Quad Cities. It now includes far southern Washington County, as well as much of Louisa and Muscatine Counties. The severe to extreme drought areas in the southern tier of Iowa are unchanged from last week's Drought Monitor. The abnormally dry conditions near the Interstate 80 corridor and up to Highway 30 in east-central Iowa also remain the same.

Dry south and wet north, by the numbers

Southern Iowa has been in the grips of drought for quite some time. Precipitation deficits continue to increase in that part of the state. Precipitation includes rainfall and the melted equivalent of snowfall. Since June 1, 2017 – the beginning of meteorological summer last year – that part of the state is running more than a foot behind. Ottumwa is the furthest in the red not just in KCRG-TV9’s coverage area, but for the entire state. There, precipitation is a whopping 20.33” below normal since June 1, 2017. These are the top precipitation deficits in this region of the state: 1. Ottumwa: -20.33” 2. Fairfield: -15.30” 3. Mount Pleasant: -14.24” 4. Clutier: -13.87” 5. Lowden: -10.23” Northern Iowa, on the other hand, has had no problem getting rain and snow. These are the top five surpluses on our side of Iowa: 1. New Hampton: +13.13” 2. Waucoma: +11.40” 3. Ionia: +11.25” 4. Charles City: +10.47” 5. Tripoli: +9.04”

Lack of August Wind

Aside from within thunderstorms, August is not known for wind. In fact, it’s the least windy month on average. Since Saturday, we haven’t been able to buy a breeze. Average wind speeds have been 5mph or less, which doesn’t help with any humidity relief. One of the key reasons why August is the least windy on average is due to the average temperature gradient (spread) across the country this time of year. When the air is closer in temperature, there’s less of a pressure gradient, meaning less wind overall.
