Back Door Fronts & The Week Ahead

Watch NBC Action News HD from 8-9 a.m. and at 5 & 10 p.m. for the latest on the week ahead and our next storm!

Good Sunday bloggers!  I hope you enjoyed the snow yesterday morning, because the 'chinook' or snow eating winds erased our white ground very fast!  Highs topped out in the mid to upper 40s yesteday, and I think today will be about about like yesterday or slightly milder with no snow.  

Before the snow melted, Windy in Paola had a chance to play in the wintry fun.  Thank you to Deb Pannell for sharing the picture!

 

 

The next several days will be fascinating from the standpoint that Kansas City will right on the edge of a broad area of low pressure.  The upper level low is going to linger over the Great Lakes and spin a couple of back door fronts and disturbances in our direction.  The first little weak front will head into our area late today.  This may turn our winds a little more NNW versus WNW.  Also, highs will likely be a couple degrees cooler by Monday.

For today, clouds will likely return sometime late in the afternoon, but any flurries or snow showers should stay closer to central Missouri.  Our best snow chance will occur later Monday or Monday night as a vort max drops southeast in the northwest flow aloft.  On the map below the 'x' over Iowa is the disturbance that will give us a chance of snow showers or flurries, and also reinforce the coolish air through Tuesday.  Also, I labeled the ULL off the West Coast that could may bring us some rain/snow later in the week.  The map is the 500mb forecast from the 6Z GFS.

 

With the back door fronts making it to Kansas City or just west, our viewing area will be right on the edge of the warm air and the chilly air.  Just look at the forecast temperatures on Monday, as highs will be in the 50s and 60s over the western Plains.

The warm air will eventually win out and move in by Wednesday.  Highs should be in the 50-60 degree range on Wednesday and Thursday.  The best chance of reaching 60 will be on Wednesday.  The warm-up will occur out ahead of our next storm system which should arrive later Thursday or on Friday.  The models will be all over the place the next 2-3 days, likely showing a big storm, no storm, and somewhere in between.  We believe this is the repeat of late November, and as a result this storm should bring Kansas City some precipitation.  We will be adding more thoughts on this next storm later today.

Thank you for stopping by Kansas City's #1 source for weather information!  If you have questions please let me know, we love to hear from our bloggers.

Boo back door cold fronts!

Seriously, I wish the back door cold front would hold off to our east. I have been looking forward to that warmer air, a nice break after last week. I also look forward to hearing more about the post warm-up weather forecast when the models are in more agreement.

Thanks!

Bob ***************** Bob, At least these weak fronts have Pacific air behind them. Not the true arctic blasts which we will get a taste of again this winter! Jeremy

AWwwww thanks for posting Windy's picture Jeremy!  Warm rays of sunshine here in Paola today, up to 45 but still a stiff wind coming from the North-Northwest. Have a great day!

Thanks for sending the picture!  Outside of the breeze today is another fine day!

Had some snow up here in Trenton last night.  All has already melted with the sunshine today.  The storm due in at the end of the week will probably give us some snow that will stay around longer than the few hours this snow stayed....still looking forward to that 10"+ that Gary thinks will happen at the first of next month.  I have a good feeling that near the Iowa border will have the bullseye.  Hopefully that good feeling comes to fruition, cause that would give us a great chance of the big one.

This doesn't look like the big one later this week.  If it plays out close to the last time around the low should strengthen east of our area.  I still think precipitation is possible late Thursday or Friday.  Better chances of snow would likely be north, as is the case most of the time since it is usually a little colder.

That split flow really shows up good on the GFS. However, it is only in its beginning stages so there is always a delay in the active weather pattern.

********************

It looks like we'll see something Thursday night - Friday.  Then the really active part of the pattern would occur about 7-9 days after that.  If memory serves me right.

Jeremy - are you expecting mostly rain out towards Kingsville?  I was kind of hoping for snow - just because our foundation needs major repairs and even 1/2" of rain comes right into the basement and floods.  If it's rain - are you expecting a lot?  Thanks.  Laura

***********************

Laura,

At this point I don't think the storm would produce 0.50" of liquid.  Still a long way off, but just my feeling at this point.

Thanks for the surface maps yesterday, it would make anybody that did not know about the LRC do a triple take!!!!
It is amazing seeing the computer models focusing in on the "Alaskan" ridge building and building up the arctic air in Canada, with out the LRC you would have needed a time machine to predict something like that as accurately and as far in advanced as Gary did.

********************

The surface maps kind of blew me away when I saw them.  It wasn't tough to see the similarities. 

I hope you enjoyed the mild weather today in St. Joe!  50 in January is a keeper!  50 may be cool compared to Wednesday though:)

It's been a wild ride weather-wise in the past month.   I just can't see a 10 inch snowstorm coming through this winter....maybe some 2 - 5 inch range storms, but that's my thought on that.  I could be way out in left field, though.  Gary, GREAT photos of your dogs!  I am a dog lover myself and a proud owner of a Doberman Pinscher.....she loves to play in the snow that we get......hope to download a photo of her in the yard if we ever get anymore significant snow!

Andrew,

The odds of a 10"+ snow are slim at best.  There have only been 16 in the history of Kansas City, with the most recent coming in 1993...twice.

So....do you guys really believe that the coldest air of the season is still ahead of us?  I honestly can't imagine it getting colder than last week, lol.

Maybe that's because I had to walk to work on Thursday morning.

*****************

I'm not sure if any of us said the coldest is still ahead, but it is a real possibility.  There is some really cold air building in Canada by later this week.  We should get a taste of it behind this next storm...not the coldest of the season.  If any of the storms over the next 4 weeks produces a good snow and arctic air follows...a night of -5 to -10 may be possible.  Still a lot of winter to go...although you wouldn't know it based on today:)

Hard to believe with the georgeous weather the last few days I've had a sick family and cannot enjoy it!  It's been a real bummer.  I sure hope Wednesday is the way it is setting up to be.  I'm looking forward to work just so I can be out in it!
Otherwise this weather has been so erratic this year.  I'm sure there has been a year like this in the past but I don't recall all these warm surges followed by cold dives!  I would just love to have about .25 in rain to moisten the ground!  We had about 1/2 if snow the other day and only teased the surface.  
I know we have had very little moisture through all these systems Jeremy, but do you see any more significant precip coming?  A single 4" snowfall this season in Lberty just seems odd.
Hope you are having a great Sunday everyone!
Jeff

We'll have to watch the trends with our next storm.  The last time through the cycle the storm was dominated by the northern branch of the jet and things didn't phase.  We'll see if things come together this time.  We should see some rain, sleet, or snow though.

last time there was a 10"+ snowstorm was in 2005-2006. We got 11.5-13" of snow! Then squat the rest of the winter.

last cycle around -12 this one so far -7 but no snow on the ground like we had in December any snow and that -7 would have been -11 to -15 oh well.  No snow for all of Jan [our driest month] 7.8 for the season. . . last year we had an 8 [22 Dec] and 13 [4 abd 5 Feb] inchers we we lucky. . . it will not happen again. . . it is 20 Jan temps have reached avg mean lows and are coming up.  Adding 3 plus minutes of daylite a day.  

Before we know it St Patty's day will be here and as is the norm; except for last year another winter and chances of snow will have passed us by.

Pitchers  and catchers report in 26 days so bring on spring for the boys of summer.
