Before I start, I want to share a photo with you from this past Friday…after midnight. The Northern Lights were seen as far south as southern Iowa. At the same time, there were a few storms across northeast Iowa. This moment was caught on camera by Rob Rustvold. He took this photo near Fort Dodge while looking north.

It has been a beautiful day with plenty of sunshine and a light wind. Some have said it could be a little bit warmer and I would have to agree. Temperatures this afternoon are in the 60s in most locations.

At 9:22 this evening you will be able to see the International Space Station for 3 minutes traveling from SSE to ESE…it will be low in the sky. If the clouds stay away, there is another chance at 10:57 pm for 6 minutes. It will travel from the WSW to NE and will be high in the sky.

The current map shows high pressure over the Midwest and Great Lakes while west of Iowa there is an area of low pressure.

The low and cold front are forecast to track east during the next two days and bring us a chance of showers/storms beginning Tuesday morning. Showers and storms are forecast to be on and off through Thursday morning.  At this point there is no risk for any severe storms. Here is the WPC forecast map for 1 pm Tuesday.

The last thing we need right now is more rain. The rain amounts forecast from Monday evening to Thursday evening show most locations around 1” of rain.

1945
: An unusually cool spring and early summer continued across the region as all but one reporting station in Iowa reported a high temperature in the 40s or 50s and nearly the entire state reported lows in the 30s. The lowest reported temperature was 34 F at Rockwell City and Storm Lake. At Des Moines the high temperature was only 48 F which is their coolest high on record in June, the low was 38 F which is their second-coldest June temperature (behind 37 F on June 1, 1889), and the average temperature of 43 F makes this easily their coldest June day on record with the second-coldest being an average of 50 F on multiple occasions. The month would finish as the coolest June on record at Des Moines with an average temperature of only 64.3 F.

1860: One of the worst tornadoes in Iowa history tracked east southeast across central and eastern portions of the state eventually obliterating the town of Camanche just south of Clinton. Severe weather was first reported in western Iowa with large hail falling in Calhoun and Webster counties including 2 inch diameter stones at Fort Dodge. The first tornado damage was reported in Hardin County where the tornado passed just south of Eldora. By the time the storm system reached Cedar Rapids it was observed that there were actually two tornadic storms tracking parallel to each other, with the two tornadoes about 12 miles apart just missing Cedar Rapids and Mount Vernon to the north and south. The tornadoes continued east southeastward devastating the small towns of Saint Marys, Lisbon, and Mechanicsville. By the time the storms entered Clinton County the two tornadoes were observed to be 7 miles apart, then they merged somewhere east of Wheatland into a half mile wide funnel that killed 16 people just south of DeWitt. The worst was yet to come as the town of Camanche, nestled along the Mississippi River with a population of about 1200, was virtually wiped off the map by the large tornado before it crossed into Illinois. At least 26 people were killed in that city with more than 150 injured and contemporary press reports stating that “whatever the town was worth, less the real estate, is gone.” The Clinton Herald newspaper reported that a raft traveling down the Mississippi River with 26 people on board was struck by the tornado with only three of them surviving “and they found themselves upon the Illinois shore, not knowing how they reached there, whether through the air or the water.” In total the storm left at least 134 dead, several hundreds injured, and about 2500 homeless along its path through Iowa and into Illinois.

 This Day in National/World Weather History …
 3 June 1860 → One of the worst tornadoes of the 19th Century brought death and destruction along its 80 mile path from Cedar County, IA to Lee County, IL, and came to be known as the Great Tornado of the Northwest. Camanche, IA, on the Mississippi River, was hardest hit with much of the town ruined. A boat passing by on the river was struck, resulting in 23 fatalities and the few survivors finding themselves on the Illinois shore with no recollection of how they got there. The tornado was 3/4 of a mile wide and took a total of 92 lives. It was just one of several immense tornadoes that hit Iowa and northern Illinois that day.
 3 June 1902 → A tornado said to be 1.8 miles wide swept through Javaugues, France. There was only one fatality.
 3 June 1921 → A cloudburst near Pikes Peak sent a high wave of water down the Arkansas River into Pueblo, CO. At least 70 people were killed and $20 million dollars damage was done in Pueblo.
 3 June 1959 → Thunderstorms in northwest Kansas produced up to 18 inches of hail in Selden. Crops were completely destroyed, and total damage from the storm was about half a million dollars. Hail fell for 85 minutes, while the temperature dropped from near 80 degrees prior to the storm to 38 degrees at the height of the storm.
 3 June 1989 → The Skydome opened in Toronto, Ontario during a heavy rain event. Despite the weather conditions, the Ontario Premier opened the roof with a laser beam device and everyone, all fifty thousand spectators, was drenched.
