Is That Cold Air I See Building Up?

Good morning bloggers,

Anticipation of the signs of winter weather is growing as we move through this month. Kansas City averages about 1″ of snow during the month of November.  The largest snowstorm in KC November records has been 9″, so it can happen at this time of the year.  It also can happen in October, as we learned October 22, 1996 when up to 8 inches of snow fell.  The problem is, we haven’t had much snow in many years and it would almost be shocking to our weather minds if anything more than 2″ was in the forecast.  Okay, hang on. I must have snow on my mind.  Here are the October stats:

1

What a month we just had.  It was 91 degrees and 26 degrees 13 days apart.  We had the earliest measurable snowfall in KC history when 0.2″ fell at KCI Airport.  I only saw a few wet snowflakes mixed in with the rain on the Plaza.  And, the big second week of the month, and yes in this years LRC, where so much rain fell placing us with over 7 inches of rain above average. This rain wiped out what was left of the drought conditions.

So, we move on into November, and cold air is now building up over the high latitudes.  Take a look.

gfs_T2m_nhem_20

This map above shows the temperature forecast valid at 6 AM Tuesday.  Two pockets of very cold Arctic air is forecast to build up, one over Greenland, and the second over Siberia.  The pattern is supportive for this to build stronger into the middle of next week due to a big ridge forming aloft over eastern Alaska and western Canada. We will look deeper into this developing pattern in the next few blog entries.  And, yes, some models have started to show snow close to Kansas City.

There are a few showers this morning associated with a weak storm system, and then a second fast moving weak storm may bring some rain Saturday evening.  This will be followed by a potentially stronger storm early next week.  A lot to discuss.

Thank  you for spending a few minutes of your day reading the Action Weather Blog featuring Weather2020 and the LRC.  Go to the Weather2020 blog to join in the conversation.

It didn’t snow significantly in the big years 2010, 2009 and we still had lots of snow… in reality we shouldn’t see snow till December.. I will however take it early 🙂

Fact of the matter is 3 powerhouse storms by Nov 19th. If we don’t get our first inch by then then I think we will have less than 10″ of snow this winter. If we get 5″ by then we will probably have ~25″ of snow this winter. If we get 10″ by Thanksgiving we will probably have 50″ of snow this winter.

I’m hunting up in Pike Co on family farm in NE MO, would love to see snow, hunting over a cut corn field in a covered stand. Bring on the snow ❄️

I have a trail-cam on a game trail that follows a contour along the base of the bluff 50′ east of our house, and an eight-point buck came sauntering along that trail yesterday. It was the same buck that was in our yard munching flowers last week. Nothing spectacular, but his rack has a good spread. Most of the recent activity on the game trail has been from does, coyotes and bobcats. Does and their young are daily visitors, and I’ve frightened several 6-pt bucks while cutting tall cedars in the past week, so it looks like it will be… Read more »

The low temperature hasn’t dropped below 32° out this way, but our forecast shows that will change next Wednesday night. WeatherUnderground predicts we’ll get from 1″ to 3″ of snow with a high temperature of 43° and a low of 26° next Thursday, but the NWS says Thursday will be mostly sunny with a high of 49° and a low of 30°. September was our wettest month (7.35″). October came in second (7.08″). Most of that rain came in the first few days of both months. June was our third wettest month (6.72″), but that rain came during 9 events… Read more »

Keep in mind KC has never had a 10” snowstorm in the month November.

Yeah, and 12 degrees that night. What have they been smoking?

Actually, the 12 degrees is possible. 1F recorded on November 8, 1991.

That would be devastating, given that we haven’t even yet had a hard freeze in the city.

Can’t really hide the similarities of that week, pattern length disclosure or not it’s just maps and the similarities are all there.

Both GFS models show 5-7 inches, and Gary just commented the EURO shows 10…

We might have to start paying attention to this one… Only a week out. Plenty of model runs to go.

It will most likely go north imo but who knows right. I dont want it up here yet. Once it falls thats normally it for the yr up here, white till may. Need to clean gutters and put up Xmas lights before the snow sets in.

Yes many solutions and not sure that’s a good solution if the trend is for these systems to dig south like that, it could leave us with cold and dry, with a very sharp snow no snow cutoff. I could care less about snow, we need meaningful precip as our drought isn’t over up here yet, they just stop emphasizing the drought when the growing season ends.

Lol..the snow crazies will b goin nuts with the recent gfs and fv3 runs. Stay calm. Hundreds more solutions to follow.

Geez, now you wishcasters will be blowing this blog up for the next week. The blog of modelitis. Wishcaster delight. Any mention of a fantasy storm 7-14 days out and everyone loses their collective minds.

What’s fun is when it doesn’t happen after all the excitement and wish casting. Hopefully just a good soaking rain. Also still lots of leaves on the trees, we’ll see how much everyone’s loving it if their power’s been out for 3 or 4 days.

Yes but past 3 Early October’s I’ve gotten a huge rainfall, this year actually much less than previous years and we all know how those years ended snow wise. I’m with Keith that I’m not sold on that repeating as it never did any years past. I’m firmly on the fence till I see it repeat it cannot be counted on for future cycles.

Fred

That’s my concern. If the early October rain was related to Rosa and Sergio, there won’t be a repeat of increased moisture flow…therefore, we can’t hang our ‘hat’ on the same storm system repeating itself in future cycles. If it does, it definitely won’t have the same amount of moisture to work with. It’s the classic Gary England: “Same but Different” due to seasonal variances.

Troy

The one difference though is we actually had a Western trough for a little over a week. That has been non existent in recent years. Yes, things might come together for a big rain for some last year but the kind of dynamics it takes for a major snow usually require a Western trough. I am not guaranteeing anything but this years start to the LRC did have a different pattern than the past couple years. By the way I see the latest Euro has 6-8″ across KS into MO about 6 days from now. First time its really showed… Read more »

Am I wrong in thinking that the October 5th-October 9th system was related to abundance of moisture from a series of degenerating Pacific hurricanes (Rosa and Sergio)?

If the upper flow doesn’t buckle to the west of Kansas we won’t get anything decent, there are no model runs showing this happening, and if you consider that the early October storms were just during the transition period then I don’t see this year being any different than previous years. These little NW clippers won’t carry moisture this winter south of Nebraska as the atmosphere becomes very dry. Show me a low in the SW coming out in the next 2 weeks or this winter will be yet another bust. In reference to Bill’s comments, I guess I’m not… Read more »

Yes Oct 5 to 9th storm is part of the new LRC this year. LRC started on Oct 6th

Gary: Happy Friday to you sir and to all 20/20 Bloggers. Hope everyone is having a great morning and has a great day!! What an absolutely gorgeous October it has been. The colors so far this fall have been just stunning!!!! A couple random thoughts on this still developing pattern from a history teacher who again did not stay in a Holiday Inn Express last night….which means take with a huge grain of salt!! I stated earlier this week that I am excited about the winter aspects of this developing pattern and I will stand steadfastly by that statement. I… Read more »

How has the AO and the NAO been trending so far?

The NAO dipped into the negative in mid October for the first time since last spring:

http://www.cpc.ncep.noaa.gov/products/precip/CWlink/pna/new.nao_index_ensm.html

The AO is also negative with the lowest value since last spring. The forecast models are split between slightly positive to way negative starting around mid November. It will be interesting to see what happens:

And we know this system will cycle back through in late Dec or early Jan and likely be a major snow storm.

REAL HUMEDUDE

“could be” a major snow storm in Nebraska, we have zero clue what this storm will do next time it cycles through. “Could be” a lot of different outcomes. Lets see it snow appreciably first before anointing this a snowy LRC. Proof in the pudding

Clint
Guest

Its a big enough system to have high confidence it will return, my bigger concern is that it may track to far south but most likely will produce for us. Not sure how snowy this LRC will be, its to early. There is some reason to believe that it will produce a major snow or 2

All of the local NWS employees live in the KC area, so it would be kind of surprising if they didn’t have some awareness of Gary and the LRC. It’s hard not to wonder when they say things like this:

“The next system, in this train of northwest flow disturbances, will
move into the area Monday into Tuesday. This looks like the
strongest of the systems, to this point, with much better jet
dynamics. If this were a month later, it could be a major snow
storm. But for now it looks too warm to support frozen
precipitation.”
