May 23, 2016

UPDATE: since my original post there has been another child left in a hot car to die. An 11 month old girl was left in a car Monday, in Hialeah, FL. It was 88° outside. Total is now up to 8 children. PLEASE PLEASE pay attention to your children.
Here is some of the story. Click here.

ORIGINAL:
Don’t forget your precious cargo in the backseat. Yes, I am talking about your children and pets. So far seven children has died because they were left in a hot car. I will be reminding you all summer long about this. As you walk through the parking lots take a quick at any car seat to make sure there is no child in there. If you do see a child call 911 IMMEDIATELY.

Storms and Higher Humidity Ahead

May 20, 2016

The weather lately has been comfortable and dry. Temperatures have been cooler than normal through much of May. All of this is about to change starting Monday. The humidity level increases (it will be humid next week) with a chance of rain/storms each day.

The chart below shows different computer model plots of forecast dew point temperatures. The green, straight horizontal, line marks the dew point temperature of 60 degrees. Once we start to see this value and above it is uncomfortable to some degree. The higher it is the more uncomfortable you will feel. This past week and this weekend to come, the dew point have been low…dry atmosphere. The change comes Monday. A south and southwest flow will bring more moisture north Monday and increase the humidity level. It remains humid all week until, potentially, next weekend.

1

The dew points of 60+ degrees will be the first time this year that threshold has been reached. The chart below shows the high and low dew point for each day so far this year. The lines in red are the days (8 days) where the dew-points has been 55 degrees or higher. It has not reached 60 degrees yet. So enjoy the comfortable humidity levels this weekend since it will be more humid all of next week.

2

Now that there is more moisture in the air, we have a better chance of getting thunderstorms through Iowa compared to recently. There is a front to our west most of the week. The map below shows the position of the front Wednesday morning.

More moisture in the atmosphere means heavier rainfall amounts are possible. We could be dealing with a few rounds of storms this week dropping locally heavy rain.

Not Many Warnings…So Far

May 19, 2016

The temperatures have been cooler than normal so far this month (warmer weather returns this weekend into next week). The cooler than normal temperatures are part of the reason why we have not had much severe weather so far this year. May and June are typically the months with the most tornadoes reported in Iowa.

Severe weather has pretty much missed us so far this year. The charts below are separated by the three National Weather Service (NWS) forecast offices that cover the KWWL viewing area. The map shows the counties each office covers. The chart to the side of each map shows the number of tornado and severe thunderstorms warnings issued through May 18…going back to 2003. You can see there are some years with a lot of warnings to this point and then you have this year. We are on the low end of the scale.

There is a chance of thunderstorms next week with Monday and Wednesday days to watch for any severe storms. We will continue to track the severe weather potential.

Fireball Over Northeastern US and Southeastern Canada

May 17, 2016

A fireball raced through the sky around 12:50 AM ET Tuesday, May 17, 2016. The American Meteor Society has 450 reports of the fireball across New England and southeastern Canada. Most of the reports came from Maine. A few reports were as far west as Toronto, Canada. The map below shows the locations of the reports viewing the fireball. Click here for updated stats. There were also some reports of a “sonic boom” from some witnesses.

A Chilly May…so far

May 16, 2016

It hasn’t been the warmest of days lately. The last time Waterloo had high temperatures near normal was May 8. We had just one day with temperatures above 75° and it was 87°. The 87° reading is also the warmest temperature so far this year. Through May 15th, the average monthly temperature at Waterloo is 3.8° below normal. The chart below shows the high temperatures (red bar) and the low temperatures (blue bar) for the month of May through the 16th. The pink dots are the normal highs for that day and the light blue dots are the normal lows for that day as well.

The map below, issued at the end of April, shows the temperature outlook for May. In eastern Iowa there was a low chance of above normal temperatures.

The 6-10 day outlook (below) issued today,  for May 22-26, shows above normal temperatures are likely. High temperatures get back into the 70s Saturday and close to 80 Sunday and Monday.

A Look Back: “Charles City Tornado”

May 15, 2016

May 15th marks the 48th anniversary of what Iowans know as the “Charles City Tornado.”  This tornado was part of a major outbreak across the Midwest between May 15th and 16th, 1968.  In Iowa, the tornadoes caused 18 deaths and more than 600 injuries.  (Read more about this event, picture included, from the National Weather Service in La Crosse, WI)

May 15 Charles City Tornado

The morning of May 15th started off with several reports of 2.5″ to 3.0″ size hail (tennis ball and baseball size) across many locations in eastern Iowa.  The atmosphere had time to recover, and by the afternoon several tornadoes struck the eastern part of the state; Two F5 tornadoes (winds 261+ mph) struck, along with two F1 tornadoes (73-112 mph), and one F2 (113-157 mph).

The first F5 tornado tracked through tracked from near Hansell in Butler Co., through Chickasaw, Floyd, Franklin and Hardin counties.  The F5 tornado tracked right through the heart of Charles City in Floyd County.  More than 350 homes and businesses were destroyed  in the city.  The tornado was on the ground for 65 miles in total, and destroyed about 2,000 homes total.  In Charles City alone that afternoon, there were 15 deaths and 450 injuries.

Oelwein and Maynard also took a direct hit from a second F5 tornado that Wednesday afternoon.  The tornado destroyed near 1,000 homes, and killed five people before falling apart near Randalia.

Below is the surface map from the morning of May 15th.  You can see a low pressure system located in Nebraska, with a stationary boundary draped across the state of Iowa, and a cold front extending from Nebraska down through Mexico.

charles city_______________________________________________________________________________

May 15, 1998 was also a violent day in Iowa for severe weather.  A severe weather outbreak resulted in at least 43 of Iowa’s 99 counties, and produced 13 tornadoes.  One of those tornadoes struck Washington, Iowa, packing winds 158 mph to 206 mph.  While there were no deaths reported, 47 people were injured from that tornado.

Cold Sunday Morning

May 15, 2016

It’s feeling more like late October or late March across eastern Iowa this weekend. Lows Sunday morning across eastern Iowa were in the lower to middle 30s, with some outlying areas reaching the upper 20s.

DMA Low Today3D

Waterloo and Dubuque both tied their record low temperatures of 32° (2004 and 1997, respectively).  The temperature in Cedar Rapids and Iowa City were within one or two degrees of reaching the record low.  Those record, which date back to the 1920s, still stand.

Record Lows vs Actual

If you’re not a fan of this unseasonable cold weather, there is good news.  We are looking to warm things up the second half of May.

Cold May Weekend

May 14, 2016

There’s no doubt about it, if you’ve stepped outside at all this weekend, you know it’s a bit chilly for mid-May standards.  High temperatures Saturday were in the upper 40s to middle 50s.  Normally temperatures this time of year should be in the lower 70s.

The cold temperatures continue tonight.

Frost AdvisoryTemperatures will be dipping down to the lower and middle 30s, which means frost is possible.  There may be a few clouds that track through after midnight to our west, keeping the potential for widespread frost low.  However, northeast Iowa has the best potential.  Be sure to cover up plans that are sensitive to the cold temperatures, or bring them indoors. Stay warm!

Temperatures by early Sunday morning could break record lows for May 15th.

Record Lows In Jeopardy
