Now while this was going on there was an outbreak of tornadoes in Oklahoma, SE Kansas and Missouri. One of the Weather Channel Chase vehicles was toss about 200 yards and destroyed by the tornado. The people in the vehicle had minor injures but able to walk away. The other chase vehicle was not impacted. Here is what the vehicle looks like that was thrown.

There is a slight chance of storm to develop this evening ahead of the approaching cold front.

May 31 Cold Front
Late this afternoon most of eastern Iowa was mostly sunny. There has not been much cloud development in the last hour so the chances of any storms are slim.

May 31 Sat

After the cold front pushes through eastern Iowa this evening the threat for a storm to develop will end. The sky will be partly cloudy overnight.

Saturday will start out with some sunshine but it will not last long. Clouds will build up by mid to late morning. A few light showers are possible in the afternoon. Not everyone will get rain and those that do the amounts would be less than 0.10”.

Here is the rain forecast from Friday evening to Monday evening. Now that is nice to see little to no additional rain for a few days.

May 31 QPF
The next chance of showers will be Wednesday through Friday with a chance of showers/storms.

May 30

TodayinWeatherHistoryFrom NWS
1998
: A severe thunderstorm tracked roughly parallel to and just north of Highway 30 from southern Sac County to Marshall County. The storm was strongest as it moved from near Boone to Ames and through Nevada around midday producing several weak tornadoes and extremely large hail. Winds gusted to as high as 80 mph at Meservey and hail the size of baseballs and larger fell at Ames and numerous other locations, with hail stones ranging in size up to an amazing 5 inches in diameter north of Gilbert. Damage from the hail was severe with every north facing window broken out in several towns and countless thousands of acres of crops battered to pieces. More than 24,000 acres were totally destroyed in southern Webster County alone and in southern Calhoun County a Lohrville woman was injured in her car by shattering glass.

1985: A tornado produced F3 damage as it grazed Elkader while moving east northeast at about 45 mph. The tornado struck the County Care Facility just outside the city killing 2 people and injuring 10 others, then went on to devastate dozens of farms and injure another 25 people in Clayton County before crossing the Mississippi River into Wisconsin.

1965: Unusually cold weather resulted in frost and near freezing temperatures being reported at some locations across about the eastern third of Iowa on the morning of May 30th. Low temperatures included 35 F at Charles City, Fayette, Marshalltown, and Oelwein, 34 F at New Hampton and Osage, 33 F at Cresco, and 31 F at Saratoga.

1934: What would become one of the hottest summers on record in Iowa began to intensify as a heat wave in the last three days of May resulted in nearly every location in the state exceeding 100 F on at least one of those three days. The heat wave peaked on the 30th when the temperature soared to as high as 111 F near Inwood which is the highest temperature ever recorded in Iowa in May. Other high temperatures on the 30th included 110 F at Boone, 109 F at Logan and Spencer, 108 F at Le Mars, and 107 F at Storm Lake. Des Moines and Sioux City also set their respective May records as both reached a high of 105 F. Amazingly this extremely hot weather came only a few days after unseasonably cool temperatures in the 30s had been recorded across much of the state with frost on the 25th and 26th. In fact, at Boone the low temperature on the morning of the 25th was 30 F so the temperature at that location rose by 80 F in just five days. To put this into perspective, the largest temperature range ever recorded across the state of Iowa during the entire month of May is 88 degrees.

1899: At least five significant tornadoes touched down in western and northwestern Iowa killing one person and injuring more than a dozen others. The oldest known photograph of an Iowa tornado was taken on this day near Kingsley in Plymouth County.

1879: A significant tornado outbreak produced several particularly violent, long-lived, killer tornadoes across portions of Kansas and Missouri as well as at least three smaller tornadoes in southern Iowa. The first of these passed just southeast of Clarinda destroying a railroad bridge but largely affecting only rural areas. An observer in Clarinda noted that the storm was “accompanied by the most terrific hailstorm remembered by the older citizens.” A second tornado produced F3 damage in Appanoose County as it passed a few miles south of Cincinnati leveling a farm house and killing a man inside. A third tornado destroyed several farms and buildings on a path across Adair County, resulting in dozens of injuries but no reported fatalities. At Des Moines the Weather Bureau observer noted that straight-line winds did significant damage to trees and crops throughout the area, and a rapid fall of 2.62 inches of rain produced flash flooding in the city that flooded a number of homes and basements.

TodayinWeatherHistoryFrom NWS
1965
: Unusually cold weather resulted in frost and freezing temperatures across much of the northern half of Iowa on the mornings of May 28th and 29th. On the 29th reported low temperatures included 31 F at Grundy Center and Oelwein, 30 F at Decorah and Grinnell, 29 F at Anamosa, Fayette, and Waterloo, 27 F at Saratoga, and 23 F at Independence.

1947: On the morning after the incredible snow storm of May 28th high pressure moved across Iowa, providing light winds and clear skies with snowpack in place across much of the state. This resulted in the latest general spring freeze on record in Iowa with freezing temperatures especially prevalent across about the northwestern two thirds of the state. Low temperatures recorded that morning included 23 F at Cherokee and Primghar, 25 F at Le Mars and Spencer, 26 F at Ida Grove and Sioux Rapids, 27 F at Sioux City, 28 F at Audubon, Denison, Elkader, Grundy Center, and Logan, and 32 F at Des Moines. At numerous locations across Iowa including Des Moines this remains the latest spring freeze on record.

1934: What would become one of the hottest summers on record in Iowa began to intensify as the temperature exceeded 100 F at numerous locations around the state. At Des Moines the temperature reached 104 F which remains the earliest date on which a 100 F or higher temperature has been recorded at that location. Other high temperatures included 104 F at Little Sioux and Pocahontas, 105 F at Knoxville and Winterset, and 106 F at Carroll and Guthrie Center. Amazingly this searing heat came only two days after unseasonably cool temperatures had settled across Iowa, with low temperatures of 42 F at Decorah and 38 F at Cedar Rapids and Olin on the morning of the 27th.

This Day in National/World Weather History …
 29 May 1914 → Shallow river fog contributed to the collision of the CP Liner Empress of Ireland and a Norwegian coal ship, The Storstad, in the St. Lawrence River. The liner sank in 25 minutes drowning 1,024 passengers.
 29 May 1953 → An F5 tornado destroyed a large church near Fort Rice, ND. The pews were jammed four feet into the ground. Parts of a car were carried for half a mile.

More Showers/Storms Through Friday


UPDATED at 4:30 PM

Tonight: Mostly cloudy with a 40% chance of showers/storms. Some severe weather is possible south of Waterloo this evening. Low: 61-67. Wind: S 5-15 mph.

Wednesday: Mostly cloudy with a 60% chance of showers/storms. High: 78-83. Wind: S 10-15 mph.

Wednesday Night: Mostly cloudy with a 50% chance of showers/storms. Low: 66-68. Wind: S 10-15 mph.

Thursday: Mostly cloudy with a 70% chance of showers/storms. High: upper 70s.

Friday: Partly cloudy with a 50% chance of showers/storms. High: low 70s.

Saturday: Partly cloudy with a 30% chance of showers/storms. High: mid 60s.

Sunday: Partly cloudy. High: mid 60s.

Monday: Mostly sunny. High: upper 60s.

Tuesday: Mostly sunny. High: low 70s.

Today has been mainly dry with areas of sunshine warming the temperatures this afternoon from 68 in the north to 81 in the south. The dewpoints are also much higher than the past few days with those readings in the 60s and low 70s . You probably noticed the increase in humidity. Most of eastern Iowa is south of the front where it is warmer and muggy. Here is the surface map this afternoon.

May 28 Current Map
South of the warm front, across southern Iowa, the condition of the atmosphere is favorable for severe storms (large hail, wind and isolated tornadoes) therefore a TORNADO WATCH is in effect until 10 pm.

May 29 Tor Watch
The storms this evening across southern Iowa could also produce very heavy rain. Heavy rain on saturated ground could cause flash flooding so a Flash Flood Watch is in effect tonight across southern Iowa.

Blog Graphic 1
After the storm chances tonight the next best chance of showers/storms will be Wednesday afternoon. Here is the forecast map for Wednesday evening.

May 28 Wed Eve Sfc
Not only is there a chance for heavy rain tonight across southern Iowa, but heavy rain is possible with any of the rounds of storms forecast through Friday for all of Iowa. Here is the general rain forecast from the WPC from Tuesday evening to Friday evening.

May 28 QPF
In addition to the potential for heavy downpours there is a slight risk for severe storms as well through Thursday. Here severe weather outlook through Friday.

May 28 Severe WX
Finally this storm system will move east of the area Saturday as shower/storm chances taper off. High pressure will cool the temperatures a little and lower the humidity for a couple of days. The best part…a few days of dry weather in a row…Sunday through Tuesday.

TodayinWeatherHistoryFrom NWS
1965
: Unusually cold weather resulted in frost and freezing temperatures across much of the northern half of Iowa on the mornings of May 28th and 29th. On the 28th reported low temperatures included 32 F at Cresco, Primghar, and Sibley, 31 F at Grundy Center and Sioux Center, and 30 F at Inwood.

1947: One of the most unusual weather events in Iowa history occurred as an intense low pressure system moved northeast across Missouri and into the Great Lakes region, passing over the far southeastern corner of Iowa. Meanwhile an unseasonably cold area of high pressure spread down the northern plains bringing record breaking cold temperatures to much of the region. A heavy snow storm tracked along the northwestern side of the low across eastern Wyoming and Colorado, Nebraska, Iowa, Wisconsin, and into northern Michigan from May 27-29 producing unprecedented snowfalls for so late in the spring. In Iowa the storm struck on the 28th with most precipitation in the south coming in the form of thunderstorms and rain, sometimes mixed with sleet and snow, while across about the northern half of the state the precipitation fell almost entirely as snow. Measurable snow was recorded at most locations north of a line from Council Bluffs to Dubuque with reported accumulations including an incredible 10.0 inches at Le Mars, 8.0 inches at Cherokee, 7.5 inches at Waukon, 6.0 inches at Alton and Hawarden, 5.0 inches at Cushing, Iowa Falls, Milford, and Northwood, 4.5 inches at Mason City, 2.0 inches at Waterloo, and a trace at many locations including Des Moines. In Nebraska several locations received 10 to 12 inches of snow and in Wisconsin 8 to 10 inches fell in a narrow band from Gays Mills to Green Bay. To put into perspective how unusual this event was, no snow has ever been recorded anywhere in Iowa at a later date in the spring, and the total of 10.0 inches at Le Mars was the highest snow accumulation on record in Iowa any time in the month of May until it was bested by the storm of May 1-3, 2013. A series of heavy rains in the following several weeks combined with the snowmelt from this storm to produce historic flooding across many parts of Iowa in June of 1947.

1906: A late season statewide frost visited Iowa on the morning of May 28th. Low temperatures included 32 F at Atlantic, Denison, Elkader, Iowa Falls, and Webster City, 31 F at Inwood, and 30 F at Fayette, Ida Grove, and Washta. A hard frost was reported at many locations across the state but crop damage was mitigated by the brief duration of the freezing temperatures.

This Day in National/World Weather History …
 28 May 1881 → The U.S.’s record 12-minute rainfall was set at Embarrass, WI, with 2.30″.
 28 May 1963 → A tropical cyclone struck Bangladesh killing 11,500 people.
 28 May 1987 → Up to 13 inches of rain fell across parts of Oklahoma, causing severe flash flooding. Thousands of people had to be rescued from their homes.
