Below is part of the summer forecast that was issued by Jeremy Nelson - Meteorologist at WISN in Milwaukee. Specifically, this is for June. He issued it on May 27th in the WISN Weather Blog noting significant rainfall and a specific stretch of severe weather in the area a month in advance.

"June looks like the wettest month of the summer. Active periods for weather to watch for come around June 7-9 and then a wetter period the last week to 10 days of the month. This is when the ‘signature’ storm should occur. Severe weather season should heat up in June, and likely will be the most active of the summer. Several disturbances will pass by in the more active parts of the pattern."

So, how did June end up?

Record rainfall


Specifically, how did the last 10 days of June pan out? Was it wet? Was it active? Sourcing the NWS data from Milwaukee, the entire month yielded 6.93 inches of rain. The last 10 days produced 3.84 inches of that total. Over half of the rainfall in the month was in that last 10 days.

Looking at the severe weather that occurred in June, the first 17 days of June, there was only ONE storm report in southeast Wisconsin. ONE. From June 18th through the 30th here is the tally:

Tornado Reports: 4
Hail reports: 4
Wind reports: 15

June 21st active storm day in SE Wisconsin.


Jeremy learned the LRC during his time in Kansas City from Chief Meteorologist Gary Lezak. He has been able to take that knowledge to Milwaukee and excel in that market using the LRC.

Using the LRC provides a HUGE advantage if used correctly. Imagine the dollars that can be saved for YOUR business in properly planning retail events, distribution, or safety of your business resources/assets. Contact us for more information. We would love to talk with you!

Happy Independence Day weekend everyone,

A tropical flow of air is moving out over the plains states this holiday weekend.  A weak cold front will be tracking across the northern plains and then it will weaken considerably as it drops south into the central plains.  This front is associated with a strong wave aloft tracking across the northwestern United States into the US/Canada border area of the northern plains, but it is July and the flow aloft is getting closer to it's weakest point which will happen in the coming weeks.  This combination and clashing of the tropical flow from Mexico and the upper level energy in the northern plains will likely lead to excessive rainfall in many spots this week. 

In Kansas City, it was a rather wet June. 5 to 13 inches of rain fell in and around the Kansas City Metro area.  5 inches north near KCI Airport, and just 30 miles to the south 12 to 13 inches of rain fell. But, this was during the first 19 days of the month. Since the 19th it dried out and today was the 14th day in a row without measurable rainfall, but this streak is about to end. We will check back in later in the week and see how much rain fell.

So, how is this pattern in July still "the same" one from last fall and through the winter?  According to this year's LRC we have been in around a 60 day cycle, give or take a few days.  We are currently in the part of the pattern that brought the cold October, the snowy December and February, and the cold first 20 days of May. But, it is July.  Take a look at the end of April trough coming into the western states and how it compares to this week. This first map shows the July 2nd 500 mb flow with the April 29th position of the jet stream drawn over the top of it. It fits so well that it looks like I am just drawing the flow that we are currently in:

More in a few minutes....  Gary

And, here are the two maps that I am comparing below:

Once again, the two maps above are showing the 500 mb flow on July 2nd, and April 29th. These dates are 64 days apart. The cycle length of the LRC may be about to go through a slow transition as next years weather pattern begins to evolve, but hold on as I don't think this process has happened yet.

Let us know if you have any thoughts or questions.  We would love to have any feedback on this comparison and on the LRC in general.

Good Friday morning everyone,

Yesterday was the big day to present the LRC at the American Meteorological Society's Broadcast Conference in Miami.  The president of the AMS was in attendence as well as 175 meteorologists and broadcasters from around the nation.  This conference had 70 more people attend than last year in Portland.  There were a lot of questions from the crowd and we ran out of time with about 20 more attendees waiting to ask questions.  There were no real skeptics after the presentation was done and the way we tied the  MJO into the LRC seemed to make  it more understandable. I will post the presentation on this site sometime next week.

Have a great day!  I have three more days in Miami before heading back to KC.  I will go into where we are in the cycling weather pattern soon.  As July approaches we are now going into the weakest part of the LRC since it set-up last October.  But, we still  believe it is the "same" pattern that is still cycling from last fall, winter, and spring.  What will it mean for July?  More on this coming up soon.  Let us know if you have any questions or comments.

Good evening everyone,

I am on my way to Miami Beach this week to present the LRC to the Broadcast Conference of the AMS.  When I return we will try to post the presentation on this site. 

Summer is settling in, it began this morning. The heights are still rising and the weather pattern that set up in the fall is weakening, but still there and cycling.  There is a lot to discuss on how the LRC can be used in forecasting during the summer months as it is reaching its weakest point before a major transition begins with next years LRC approaching. 

We will add more thoughts soon.
