White Christmas and Cold Intensification

Merry Christmas bloggers,

Snowfall amounts were as predicted, 1/2″ to 1″ with some locations just over 1″.  Trenton, MO received 3.2″ and this is where we expected the heavier snow. Now, did the snowflake contest end? Remember, there needs to be 1″ of snow at 41 Action News as measured by one of our meteorologists.   I was the meteorologist with the ruler at the station and well…

We measured 0.8″ of snow here on the Plaza, so the Snowflake Contest rolls on. Gary measured 1.3″ in Overland Park and the National Weather Service measured 1.1″ in Pleasant Hill. So, what is going on? Well take a look at these radar images and it explains why the Plaza had about 0.5″ less.

Around 350 AM as the main heavy band of snow was moving across the city you can see the heavier snow is split around the Plaza with heavier snow showers from southern Platte/Clay and southern Johnson counties.

11

Then, by 405 AM the heavier snow connected, but east of the Plaza, so this really shows why the Plaza had a bit less. Also, the snow was moving east at 70-80 mph, if it was moving at 60 mph then the Plaza would have had the extra 0.5″ regardless.

13

Now, we turn our attention to an increase in the cold and new small snow chances.

SUNDAY AFTERNOON: It will be sunny and cold with highs in the 20s. Wind chills will be in the teens.

4

CHRISTMAS NIGHT: The kids should be sound asleep as Santa arrives in KC. Temperatures will be in the teens, so Santa will feel right at home. The wind will be west at 5-15 mph.

5

CHRISTMAS MORNING: This will be a great morning to stay inside and open presents as it will be mostly cloudy and dry with temperatures 10° to 15° with a 5-15 mph wind and wind chill values near zero.

6

CHRISTMAS AFTERNOON: A legitimate Arctic front will be moving across the region. We will see highs around 30°, but look at Omaha, 14°, how about a high of -3° in Rochester, MN. There will be many clouds, but dry.

7

TUESDAY MORNING: Eek! It is going to be very cold with lows around 10°. If it clears lows may drop to 5°.  Look at Omaha, -1° and Rochester, MN, -10°. Flurries are possible, but we do not expect any measurable snow. We do need to watch this for a dusting.

8

TUESDAY AFTERNOON: The sky will clear, but highs will struggle to 20°. Highs along I-80 from Omaha to Chicago will struggle to 10° despite sunshine. Rochester, MN will have another day with highs below zero.

9

So, the weather pattern for the last week of 2017 is evolving in to one in which we will have blasts of Arctic air as disturbances race in from the west-northwest. This sets us up for two to three chances of small snow systems. They are timed for Thursday and Saturday as it stands now. We still have to watch the Tuesday set up.

Here is our latest forecast for the total snowfall potential the next seven days. You can see, it is not much, but we have to watch the systems at the end of the week for more potential.

Merry Christmas!

Please don’t drink and drive

The NWS predicts our low temperature will be -1° tomorrow night.
They haven’t made a prediction for the low on New Year’s Eve, but they say the high will be only 13°.

The gfs gives a possible dusting on the 26th, a storm for the 28th-29th but most snow stays in northeast mo, and it gives us 2-3 inches on new years eve. Let’s see how all of these chances evolve.

Heat will spoil it for me by reminding me it’s 10 days away, but that 6/10 of inch liquid equivalent into January would be awesome and much needed

Gary and Jeff: Merry Christmas Evie to you and to all the 20/20 Bloggers!! Wound up with around 1.3-1.5 here in Washington Creek Valley-one off the heavier bands tracked right over me so I kind of lucked out. That gives me a total of .60 for the week-may not have broke the ice, but I sure did buy and ice pick and took a chunk!! 🙂 It was so beautiful running this morning…snow underfoot….a north wind blowing….creeks and back end of ponds with ice…a true eastern Kansas winters morning!!!! Most importantly for this post: Merry Christmas and Happy Holidays to… Read more »

A quarter of an inch in one day I mean

Wow it’s been so long I don’t know what .25 of precip looks like, looking forward to the day I can get that much precip since it’s been over 60 days here. Maybe for weather of interest my area can set a record for longest number of days with less than a quarter inch of precipitation

It’s been 80 days in western Kansas since 0.10 inches fell from a storm!!

So I got my snow melted and measured the precip from the 51/2” inches of snow we got. I got .25” of liquid from the melted snow. We’ll take it,

Our 2 1/8″ melted to 0.12″.
It wasn’t powder, but I thought it would be wetter than that.

The EURO looking awful the next ten days for any precipitation. Everything missing to the east. See if the GFS holds its rather active pattern with next run.

Looks like winter is finally here. The cold doesn’t look like it’s going to give any time soon, at least the first week of January. We could use these quick clippers to pad our totals, and maybe a bigger storm before the year ends. The models are trending in the right direction.

We need to remember the stormy part of the pattern will return in January, and I think they will produce. After weeks and weeks of frustration, the pattern finally “gave” as Gary says.

Well I’m still holding out a very slim bit of hope that it will snow 1″ on Wed….. that’s my prediction for the snowflake contest…. but it is pretty what we have out there right now… I think we got about an inch here in the Armour Hills area…

If its melting probably going to need to keep an eye out for black ice as that cold front ushers in

Looks like my tentative forecast on the previous blog matches up with what Jeff just put up. We could get up to an additional inch +/- through next Saturday. Will be interesting to see how these small waves develop. If only there was more moisture to work with in this cold arctic air.

Time to put out a lot of bird seed so our fine feathered friends will have the calories to get thru this bitter cold.

Funny how this cold air mass of -22F is forecast over us by Jan 2nd and yet AO is neutral to positive…. almost like the AO doesn’t matter… or maybe that Ridge / our LRC makes it so a positive AO actually brings in Arctic air in this pattern as the blocking would cause the cold air to be funneled too fast into too narrow of a river to cause any substantial Arctic air to build up?!

Wow, didn’t notice that! That would be by far the coldest I’ve ever experienced!

12z GFS shows 3 more chances with widespread 3-6 inch additional amounts by January 3rd

It looks like it’s still snowing in that picture, so it could have possibly reached another 2/10 of an in. after that measurement. 🤷🏼‍♂️🙅🏼‍♂️
