Topic: Wet start to June

Last weekend the month of May concluded on a wet note, and the month of June began very wet as well. Many weather observers around the state reported 1-2 inches of rainfall over June 1-2, while a few others received nearly a month's worth of rain producing flood warnings on several local rivers and streams. In the northern counties both Hibbing and Kabetogama reported over 3.5 inches of rainfall, while in west-central areas Dawson reported over 3 inches. The heaviest rains were concentrated in central and southern counties. Belle Plaine reported nearly 5 inches as did Onamia. In the south Redwood Falls reported 4.75 inches, Luverne 4.13 inches, and Winnebago 5.29 inches. Many farmers reported standing ponds of water in their freshly planted fields. Portions of the Crow River, Sauk River, and Buffalo Creek all rose to near or above flood stage due to heavy runoff.

Yet more rainfall for the weekend is predicted, though more modest amounts ranging from 0.25 to 0.75 inches. Some farmers are still trying to wrap-up soybean planting for the season and they are hoping the rainfall will miss them this weekend. In addition a number of growers are concerned about the loss of nitrogen fertilizer through the soil profile as a result of the heavy rains that came at the end of May and beginning of June. Where there is a question or concern about whether to apply additional nitrogen to a corn crop that has already emerged, growers are encouraged to read the latest edition of Extension Crop News where you can find recommendations related to this topic.

More large hail was reported on Thursday, June 5th in some southwestern counties, but much of the other severe weather remained well south of Minnesota.

Weekly Weather potpourri:

The United Kingdom Meteorological Office had two significant press releases this week: one described their work in assessing future climate change implications for heavy rainfall events and they found that rainfalls of 1 inch or greater will like increase in frequency a great deal; the other press release is a fascinating description of the forecasting tools that were used to assist the Allies in the D-Day invasion of Normandy 70 years ago.

Tuesday, June 3rd brought an outbreak of severe weather to portions of NE, IA, KS, and MO. There were 15 reports of tornadoes and hundreds of reports of large hail and strong thunderstorm winds. One observer in NE reported 3-inch diameter hail, tea cup size hail according to the NOAA Storm Prediction Center.

According to the weekly USDA drought assessment "drought in the U.S. improved slightly in May 2014, but most of the improvements were in the central states. Intense drought was entrenched in California, parts of the West and Southwest, and in Texas, Oklahoma, and Kansas. The NDMC and drought observers documented impacts related to water supply for agricultural and municipal use, wildfire, and forecasts of reduced agricultural production. Moderate drought is only present on less than 4 percent of the Minnesota landscape.

As of Thursday, June 5, 2014 there was still some ice on Lake Superior around Picture Rocks National Lakeshore in upper Michigan. It was expected to remain a few more days, the latest appearance of ice on the big lake since 1996.

MPR listener question: How does the daily maximum temperature in Minnesota vary from summer to winter in terms of the time of occurrence? It seems in the summer that it actually occurs after I get home from work.

Answer: Assuming you have a day job, you are absolutely right! In winter, the time of the daily maximum temperature is most generally between 2:00 and 3:00 pm, lagging solar noon (maximum elevation of the sun) slightly. However, in the summer (June, July, August), the time of maximum daily temperature is typically 5:00 to 6:00 pm, lagging solar noon by several hours. Thus, that cold lemonade, ice tea, or beer you are drinking on the front porch after work is not just to relieve the stress of your work day, it is also intended to make the hottest time of the day a little more tolerable!
