The Heat Wave Breaks with cooler air here today!

Good Sunday bloggers,

Some locations received some great rain, too much rain and not enough rain. Welcome to the 2018 weather pattern in our area. There was some severe weather and flash flooding Saturday. Let’s take a look at the reports and then we will look ahead to the 4th of July.

There was a corridor of severe weather Saturday from the Plains to western Great Lakes. KC was on the eastern edge.


As we look closer at the severe weather reports there was 1″ hail around Platte City with flooding northwest of Leavenworth.


Platte City, MO hail:


There was also 1″ hail near De Soto, KS and 60 mph winds in Eudora, KS.


Let’s shift to the flooding part of the weather. There was 4.25″ near Atchison, KS and in Potter there were numerous roads closed. This location does not need anymore rain for awhile. But, as you will see below it is quite localized.


This is the radar estimated rainfall totals from mostly Saturday. Nebraska and Iowa had extensive rain which has been occurring all summer. It has been a different world up there. The red colors are 4″-6″ rainfall amounts.


There were rainfall amounts of 4″-7″ along highway 237 near Iatan. You can see why flash flooding was a problem. Remember, flooding kills more people per year than tornadoes and lightning. It is #2 to heat.


The 4″-7″ rainfall was in a relatively small area compared to the viewing area. Rainfall amounts in most locations have ranged from zero to 0.75″. This is good for most, but we need more rain.


Highs today will be in the 80s after the rain. So, the heat wave ends at three days. Monday will see highs near 90° after lows in the 60s. So, we have one comfortable morning. Then, Tuesday-Thursday will see the heat return with highs around 95°. We have a chance for our third heat wave, but some of those days may fall short due to clouds and the slim chance of an isolated thunderstorm. You can see the scattered showers and thunderstorms across Illinois and Indiana on Tuesday. This is a weak disturbance that will drift west. So, the 4th of July and Thursday may see more clouds and the chance of an isolated T-Storm. This could keep highs under 95. So, this weeks version of heat will be just a few degrees cooler than last week. Heat index values will be 105°-110°, so still stifling.


The anticyclone, “heat wave creating machine”, is being shoved to the east by our current storm system.


The anticyclone will return, but come in from the east. Sometimes, when they build in from the east they are cluttered with disturbances and cooler temperatures at around 10,000 feet. So, this means there are more clouds and the chances of isolated to scattered showers and thunderstorms. This will be the case Tuesday-Thursday. So, if you get a downpour on the 4th of July, it won’t last long, it will cool you off and don’t cancel any plans. Now that being said, if you are out and about, keep an eye to the sky.


4TH OF JULY: The chance of rain in any one location is just 10% at this time.


Have a great holiday week,

Jeff Penner

    Thanks Jeff! Got around 3/4″ to 1″ here southeast of the stadiums.

    Thanks Jeff

    According to the NWS KC
    “The stretch of temperatures we just had over the past 3 days at KC are the hottest 3 day period Kansas City has experienced in almost 6 years! Last time KC had a warmer 3 day period was 7/24/12 – 7/26/12.”

    The biggest difference between 2012 and 2018 is rain, in addition to higher humidity. While we have yet to reach 100 degrees due to the higher humidity, I suspect we will be in for a hot and humid summer unless the dome of high pressure expands/stays and drags in drier air from out west.

    It’s been fairly cloudy here in Prairie Village with temp showing at 83 degrees. The sun is trying to come out. I hope it does because I’d like to get some swim time in. Have a great Sunday everyone.

    Since records have been kept the last 2 months (since 5/1) rank as the 2nd warmest. Ranking number one in the same time period is 1934.

    So, who knows.
    I do remember a whole lot of cloudy days last winter. Maybe they will be a factor in helping us this summer.

    Much nicer today as we sit at 82 vs 98. Picked up just under 2 in of rain. Hope your heat wave doesn’t last. I don’t miss the long stretches of super hot ex!

    Lawrence NW suburbia hit 102 w/ Heat index of 123 last Thursday = NASTY!!

    Agreeing that ’12 was arid – as opposed to usual Kansas/Midwest Summer humidity.

    I measured a solid half inch of rain from last night’s storm here in Prairie Village

    It was so hot in Chicago that the fire department needed to hose down the Michigan Avenue Bridge after the steel expanded, reducing clearance for boats

    LRC and reality couldn’t be more different.

    LRC says it’s supposed to get nice and cool for a few weeks.
    GFS 00z shows a huge ridge setting up with 100 degree heat across Kansas daily for the foreseeable future, and only 0.47″ of rainfall in the next 15 days in KC.

      That is not what the LRC says. The LRC doesn’t speak. Everything is right on schedule. In May it was very hot as the cold fronts stalled near the Nebraska/Iowa borders. North of these fronts it was very cool. Let’s see what July brings.

      I will write up a new blog by mid-afternoon.

        lol…the LRC doesn’t speak.

        • TDogg July 2, 2018 at 2:20 pm - Reply

          Yup. Thought the same thing when I read that…

          I kind of thought it did “speak” otherwise how do we get the 12 week forecast. Obviously LRC doesn’t literally have a voice but it must speak in some form? Crazy man I am, I know

          • Coachshawn July 2, 2018 at 5:57 pm - Reply

            The 12 week forecast is worthless. Just look at the temperatures that are forecasted and add 10 degrees. Not sure why anyone bothers to even look.

    • Richard July 2, 2018 at 9:22 am - Reply

      I agree. It went from crazy cold in April to crazy hot on May 1st.
      We should have had a semblance of Spring.

    I scored 1.1″ yesterday morning, we got pretty lucky as the system was falling apart as it approached and area just to my north and west got 2″ +. Our tasseling corn needed it very badly, as well as the tiny late beans that have were planted in past 3-4 weeks. Pastures were gasping and this will keep them green another week. I am hoping we can score a random pop up storm sometime this week, that’s about the only chance on the table until Friday and I’m not so sure about that setup.

    I’m thinking Humedude and F00dl3 are more reliable..
