Very Active Hurricane Season: Weather Models Threatening The East Coast & KC’s Chance Of Rain

Share on facebook

Good morning bloggers,

Hurricane season is now in hyperdrive as we look at the bigger picture. We have Hurricanes Norman, Olivia, Florence, and more development.   And, here we go again with the models.  If you remember, the National Hurricane Center had a 0% chance of development for Tropical Storm Gordon, while our prediction was at 84% chance of storm development from months earlier.  This time, we aren’t concerned with development as this has obviously occurred. This time we are highly concerned on the track as there are major implications depending on whether Hurricane Florence will blast the coast or curve offshore. The computer models have some scary solutions for the mid-Atlantic and northeastern states.  Take a look at this:

These are three of the models with two of them, the Canadian model and the European model bombarding populated areas of the United States, while the American GFS model showing it curving off shore after a major threat.  Remember, we have a tremendous insight using the LRC.  Based on the Cycling Pattern Hypothesis, known as the LRC, I would place a 55% chance of it curving out to sea and a 45% chance of one of those other solutions of it making landfall happening.  This is the part of the pattern that ends up producing a big eastern storm, and when that happens, it will deflect the hurricane back out to sea.  The question is exactly when will this happen. If it is a day or so faster it may hit the coast, and if it is a day slower it will get deflected out to sea.

The National Hurricane Center Track:

By Tuesday of next week Hurricane Florence will likely be a major hurricane and still be way off shore. The weather pattern is cycling according to the LRC and again, the speed of this storm is critical.  Let’s keep monitoring this.  Even though I am leaning in the curving out to sea as it approaches the eastern seaboard, it is definitely something that must be monitored day by day.

The dark green areas show the Flask Flood Watches which include the KC metro area, yet we are on the edge of this watch.  Look at the red around Hawaii.  Are you kidding me?  Hurricane Norman is very close to Hawaii and Hurricane Olivia must be monitored closely.  Hawaii is obviously in a hot spot this year for activity as there have now been FOUR hurricanes throwing impacts on the islands already this season.  Surf will be up. Norman will track north of the islands bringing very high surf to Hawaii.

Back west over the middle part of the nation, what is left of Tropical Storm Gordon is going to combine with another storm system to create some flooding rains.  Over 2″ of rain did fall in a few spots yesterday, and in areas that really needed it.

The models have trended towards a storm developing, combining what is left of Gordon with the next storm on schedule in the cycling pattern. Yes, we are still in the same pattern for just four more weeks and then we will welcome the new LRC in October.  For now, it is still more of the same, but slightly different.

The models have trended into the heaviest rain to be located over the eastern half of Missouri. Let’s see how this forms.  Expect cloudy and cooler conditions in KC with periods of rain or drizzle the next three days.

Have a great day and thank you for sharing in this weather experience featuring Weather2020 and the LRC.  Join in the conversation over on the Weather 2020 blog.

Heady maybe.

Looks like the other competing LRC-like pattern wasn’t so successful. They forgot to pay their domain name and now no longer exist.

I am always amazed at how another local channel is always so quick to get 90’s in forecast. I do check them to see if there is a chance they will be right but man they seem to always be 5-7 degrees to warm. Now and again they will be right but come on and give up the warm bias predictions. With that said I am liking the cloudy days but so ready for highs in the upper 50’s then bring on winter!

Look at what I just ran across. Who was talking about this a few months back?

This is saying the opposite of what some have claimed here-that wind farms inhibit precip formation, I still believe the effects of wind farms, if there are any, are local and negligible at best either way.

Correct me if I am wrong.
With the current LRC, it should in transition now. And we should be seeing subtle changes soon ?
I have heard that rain, in the few weeks before fall, helps with colors. Should be vibrant if we continue to get rain.

We are all ready for SNOW ! Hopefully a lot of it !

ONLY 1.39″? That woulda been one of biggest rains of the year down here

how about .01 since last week! Somehow a flood warning for southern end of my county, they got 2-3″ but nada in NW corner of Vernon Co. This LRC sucks

12z GFS coming into line bringing hurricane closer to the coast late next week.
If it has to hit somewhere, Washington DC would be OK.

143rd and Switzer in Overland Park….now at 3.25 inches of rain since Tuesday afternoon.

.3 Tuesday
2.7 Wednesday
.25 Thursday

What has everyone else got in this time frame? Can you share with location? Always fun to see how precipitation gets distributed, or not distributed in some cases over a relatively small area.

Gary,

Your comments on the LRC continue to puzzle. You mentioned that we are in the same pattern for 4 more weeks. We have had more rain this week than several others combined. I may be missing something but I cant understand how the same pattern that produces close to zero precip in one cycles ends up with more than 3 inches?

So, the 90% chance of rain for tomorrow ( what you told the 810 guys yesterday) is now pretty much not going to happen here ?
That’s a good thing. A lot of outdoor activities going on. Olathe has Old Settlers starting today – Sat.

The 12z NAM makes for a rainy Friday but that’s about it.

Gary, I have a question about your percentages on whether Florence makes landfall or not. 55% no, 45% yes. What is this based off of? You say the LRC, but from what exactly? Would you mind posting maps and a more detailed analysis tomorrow/whenever you have time? Also a suggestion going into the 18-19 LRC, would you be able to post a chart that shows the different cycles and what they produced so its easier to follow for us bloggers(i.e., Column 1: Cycle 1: Row 1: Dates: Produced Noreaster Row 2: Produced second noreaster)? I think a lot of the… Read more »

After regaining my composure from hysterical laughter I now tell you this-ain’t happening!! It would make the misses easier to spot (to his advantage it would make the hits easier to spot too) but nice try.

Indeed, we need to label each system in each cycle so we can follow them. The very first system in the new LRC would be 1-A, the next storm , 2-A, 3-A and so on. The next cycle would be 1-B, 2-B and so on. That way we would follow them and instead of saying this storm is connected to some random date period nobody can Remember, we could say storm #6 is due in and we could all follow that Alot easier. A nomenclature system is all we need here, but it’s imperative to label and name them or… Read more »

I have been left with only a few hundredths since last weekend somehow!?!?! I saw precip maps showing my area with 3-5″ of rain, can’t even get a tenth! HRRR is not impressive today (maybe a few pop up showers), Gordon goes too far east and takes the precip with it, how in the world can I get missed out of this setup that has produced all these huge floods in the region?
Oh yeah, I’ve been getting missed all year, its the LRC dummy!!

What kind of precipitation has to fall for a flask flood watch to be issued. I may need to set out several rain barrels.

A flask flood sounds enjoyable, until the next morning.

looks like we going to get less and less rain from this combo system. smh

Is it me or does Gordon look like its pretty much fizzled out?

I was thinking the same thing this morning. It’s not really moving or producing rain like it was a couple days ago
