An Introduction Into This Years LRC

Good Sunday morning bloggers,

Kansas City Weather Time-Line:

  • Sunday: Mostly sunny with light winds. High: 65°
  • Tonight:   Clear and cool. Low: 44°
  • Monday: Mostly sunny. A near record high or maybe we will break the record of 71°.  High: 72°  South winds gusting to 30 mph.

MONDAY NIGHT at 6:30 PM:  The Wonders of Winter special will be broadcast on 41 Action News with our Winter Forecast!

An Introduction Into This Years LRC from Weather2020 on Vimeo.

This video just scratches the surface on the developing pattern. We go through the first LRC cycle which is most likely in the 45 to 51 day range.  Last night a snowstorm showed up on the 06z run. Is it fantasy of reality?

The AO and NAO are forecast to stay neutral to negative. This will be discussed in our winter forecast that will be posted here Monday night.  This is what we want to see if you are interested in having some winter excitement and you are a weather enthusiast.

LRC Cycle 1 2017-2018 10-23This map on the left shows the pattern on October 23, and the one on the right shows the pattern on November 2nd. This part of the weather pattern brought a three week to four week stretch of colder than average temperatures. So, guess what? The chance of December being colder than average is very high. We are forecasting a cold December. Now, will it lead to above average snowfall next month? What about this winter? We will learn a lot more in the next few weeks.

LRC Cycle 1 2017-2018 11-2This has been staring us in the face for weeks now. As usual, it is easy to make too many conclusions too early. I have been trying to help you be patient.  I am somewhat excited about the winter that is about to begin.

Have a great day, and please join in the conversation on tomorrow night into Tuesday as we discuss the winter forecast truth from the Action Weather Blog featuring Weather2020 and the LRC.

    In early October we had distinct storm systems coming through that were well defined. I’m not seeing any well-defined storms yet. The pattern doesn’t look the same as October. Could those early storms in October just be a transitional period. I’ve been following the cyclical pattern at least five years now and it seems October doesn’t relate to the rest of the cycles–most years. I’m sure you’re looking for a map that signals the start of the second cycle. Have you seen it yet?

      Actually the pattern is very similar to October. The storm system approaching us this week is so closely related to October 10th.

    Gary will tell you the same. That The models are still all over the place pattern has not yet set in stone.

    240 hours ago we were supposed to have snow tomorrow. I wouldn’t trust the models right now.

    So the forecasts on the weather1 app are bogus at this point? If there is any truth to the cycling pattern, then one would expect it to have some periods of cold in December, but precipitation doesn’t seem to be there.

    Good Sunday Morning Gary. So funny that you pointed out those deep troughs. I noticed them back in October and went to the archives this past week to find the dates/patterns. I’ve been looking for them to return but they have yet to pop up on the models yet. I figured that the LRC cycle had to be 50+ days because the models don’t extend that far out to show the return yet. The return of the deep troughs and colder weather also ties in with a link that Richard posted yesterday showing the potential for a significant cooling of the upper layers over North America in mid to late December.

    I’ve been monitoring the December 6th/7th system and thought this just might be our first snow event, but am not convinced due to temperatures. Anyways, looking forward to your winter forecast, and more in-depth discussion here.

    PS, is there anyway that you can post video of your KSHB winter forecast on the KSHB web site? Appears that some folks in the larger area don’t have access to the station on their cable network.

    If Gary is right, it sounds like December may be cold and snowy, we will have our normal January thaw, and then February will finish off the winter with more cold and snow. I recall that being the forecast two years ago though, and it seemed like the storm systems never got their act together until they got further east. Hopefully things are more organized this year so they produce.

    • terry November 26, 2017 at 5:37 pm - Reply

      Not really because the last 2 or 3 winter we were never really in the right spot . This Winter seems a lot more promising As stated by Gary !

      • Richard November 26, 2017 at 6:38 pm - Reply

        Not exactly in the right spot for wet systems so far either in the new lrc.
        Dry storms yes, but not wet ones.
        We have really dried out since the end of Oct.
        I know it seems like we should get something in Dec though. Lets hope.

          Lol did you watch the video ? I guess you’re Gary got different opinions ?

          • Richard November 26, 2017 at 7:35 pm - Reply

            Yes I watched the video.
            Did you understand what I said.

            I said so far we have had dry systems, not wet ones. Since end of Oct.
            And it seems like we should get so,something in Dec. Meaning wet systems. I hope so

    This is interesting: today’s 18z GFS 500mb forecast for Dec 8 compared to Oct 24 – 45 days apart – match up fairly well.

    He’s fairly confident about colder temps, but it all depends on where the storms track and the moisture with them. No guarantees and just have to wait and see. Maybe more snow but below average precipitation?

    • terry November 26, 2017 at 7:27 pm - Reply

      With the AO and NAO being and forecast to go negative that alone could Can bring a bigger winter for as here. It last all more Promising for a better winter here by what Gary is saying and seeing ! When have not had the a Dip Negative and a NAO for awhile. Probley Since 2009/2010 that winter not sure . It has not been Dry where I’ve been at all much.

      • terry November 26, 2017 at 7:31 pm - Reply

        That’s supposed to say Dip Negative AO and NAO for a while and I will go by what Gary is seeing. It’s not been Dry much where I live at all.

    • Gary November 27, 2017 at 4:32 am - Reply

      Bloggers, I will have the winter forecast published here by 6 pm. Our winter special is on at 6:30 on 41 Action News.

    Salt brine is a proactive approach to battling inclement weather. Last year, KDOT used approximately 5 million gallons to prepare road surfaces for snow and ice. Each of the 112 sub areas in Kansas has at least 1,000-10,000gallon storage tanks.
    The fact that road salt causes vehicles to rust out – sometimes after just a couple of winters – is something everybody knows . . . As a side note, sodium chloride isn’t the only road salt available, nor is it the most effective; it’s simply one of the cheapest. Other road salts, like calcium chloride and magnesium chloride, involve more complex molecules that distribute more ions when they dissolve in water, further lowering the freezing point of water. In turn, they’d also create more effective electrolytes than sodium chloride and thus prove even more devastating to your vehicle’s sheetmetal.

    There is a trend in the models finally

    • f00dl3 November 27, 2017 at 5:15 am - Reply

      Trend I see is for the storm to bomb out over Dodge City and track to Minneapolis giving us rain and thunder not snow.
