Temperatures Surge...Colder Air Lurks...Hoar Frost Picture

Watch NBC Action News HD this morning from 5-7 a.m. for the latest on our quickly changing weather and the weekend forecast!

A quick update for everyone this morning.  Warmer air surged north overnight and temperatures made it into the low 50s in Downtown KC, Olathe, and other parts of the viewing area.  The mild air, patchy fog, and rain showers took a big chunk out of our snow pack in central and southern areas overnight.  North of the metro it has remained much cooler in the 30s, and some spots there are still dealing with icy roads.  The cooler air will spill south and in the metro we could drop into the 20s this morning, and then rebound around 30 by afternoon. 

Here is the surface map from just after 3 a.m.  Look how close we were to the cold air and a snowstorm! 

If readings do drop into the 20s we will have to watch for some re-freezing of the water that is sitting on roadways in the city.  Sidewalks and driveways could get really slick, so be aware of that this morning.

Finally, a few people mentioned they saw some weird frost yesterday.  This was Hoar Frost.  Hoar frost occurs when water vapor touches a very cold surface and freezes on it instantly.  This can happen to leaves and branches of plants, and will cover them ice crystals that look like spikey fingers.  This typically happens when the ground is much colder than the air.  Jason Ochs of Ottawa, KS shared this picture with us.  Pretty cool!

We will have an update on the weekend forecast and any possible snow chances in our next blog update this morning!  Gary will update the blog with his thoughts around 8:30 AM.

Very windy and warm here in Olathe this morning.  I'd like to put in my order to keep it this way and cancel the artic blast for this weekend. :)

I'm with you...it's been cold enough already this winter season.

That type of frost is just one of mother nature's spectacular sights.

It's 39* in NE Independence with a lot of wind.   I'm kinda surprised that the wind is so strong.  The snow is disappearing quickly too.  I think we'll get in this last half day of school!

Good Morning Jeremy,
It was so nice to have the warm up, at least it melted most of our snow here in Paola.  The temperature is starting to drop though, I'm glad to know it's going to rebound in the 30s.  Maybe one more arctic blast this weekend and we will be done with this horrible cold air, I miss being outside and am getting a bad case of cabin fever.  Winds are really picking up here 28-30mph, I guess that could help dry out the ground..maybe????  Have a good day, bundle up when you have to venture out this weekend......I'll be back to my cave and hibernating by tomorrow afternoon!

DON'T GO OUTSIDE!!!!!!  I stupidly did.  Got in my car, drove down my short snowy drive to the ice skating rink of a gravel road that I live on.  BIG mistake.  As soon as my tires hit the road, I was sliding.  I live on a small hill so I zig zagged allllllll the way down the hill. Thankfully it was in slow motion and my brain kicked in, turn INto the slid.  Kept me out of the big ditch anyway.  Now my car is parked half on half off the road.  I just pray no one else comes by because if they do, my car is history.  There is no way anyone can make it down that road.  BTW, I'm 1/2 between Turney & Cameron, when I got up the temp was 35.  Half an hr later it was 30.  What a mess.

Well, at first glimpse this morning, North of Leavenworth, we have...Nothing different than yesterday, it is windy, roads are fine and dry and still have all of our snow, think we missed most of any precipitation that fell, and after being without electric for 7 days last year with ice, I am doing the Happy Hamster Dance here this morning.

Nice picture there, we didn't get any of that here.  Well it made it up to 40.1 at 2AM here in McLouth but we have been falling ever since, currently we are sitting right at 30.0 with a wnw wind at 7.6 gusting to 20.8.  Needless to say we still have a decent snowpack and lots of ice out here.  The fog got so bad last night we had zero visibility.  I mean at 50 feet you could barely see headlights, so it was bad.

Hi Jeremy,  What about next week's forecast now?  You had snow in for Xmas eve and Xmas day.  Last night I saw you had taken it out and now it's back in again.  Think we'll have our first white Xmas this year or?

We had tons of that yesterday between 8-10 a.m. It lookedc like an ice storm. The only snow that's left is on the roads and in piles. WHY IS THERE STILL SNOW ON THE ROADS BUT NOT THE GRASS?!?!?!?!?

Well this morning I guess answers my question I  had about the wind and the storm from CA. Sounds like lots of wind here. Last night I could hear water rolling down my gutters. I thought maybe it was raining and checked, nope, it was all snow melt.

Question,
On your interactive weather map, when I click on the 5 day forecast, it says I'll get snow everyday except Monday. Yet I don't believe you are calling for snow today. Is this an example of it being a World cast and not a NBC cast?

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

The forecast you are referencing was not made by us.  So, you should click on our 7 day.  You can see the difference and the most accurate forecast.  The computer generated ones are there in case you want information from around the nation.

Love the weather almanac this morning!  No school for us today near Centerview.  I suppose there are some slick gravel roads.

What...you don't remember that day it was 100 degrees:)

We are at 32.9.  It was 34 about 30 minutes ago.  They have not closed Schools here yet. (Strasburg, LoneJack)  They have however closed Kingsville and Holden which is only 5 and 10 minutes away from us.  I am worried about my oldest son riding the bus if it drops below freezing after he leaves because they did not cancel school in time.  They only have a half day but they are taking their finals.  32.7 now just since I started writing this.  I am very concerned. My son gets on the bus in 10 minutes.  

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

I wouldn't worry too much.  The wind is helping to dry things out some.

Main roads are good up here...side streets another story...Thanking God for the blessing of the little amount of ice we did get...Woke up this morning with power and heat...hopefully the same for north of us!  

Thanks Gary and all the weather staff...you are about the only ones that will forecast for north of KC metro area!!!!

we have school in Liberty & it warmed up just enough that my hilly driveway melted enough for me to get out to work.  It looks like the snow on the grass is just soggy/slushy so when it refreezes it should be a hard mess!

Sound like a fast sledding track!  But watch out when trying to stop.

Since we don't have snow on the ground now, will that warm (and I use this word relatively) the temps up a bit for the artic blast?

I hope the wind doesn't come in with such fury as the west wind last night. Geesh, went to bed thinking 10-20 MPH overnight and BAM the house is creaking.

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

No snow on the ground here won't have much effect.  We would need no snow on the ground in the northern Plains, upper Midwest, and much of the northern U.S.  That really isn't the case though.  It is going to be very cold Sunday.

And it is so lovely to see green pasture grasses this morning with a few puddles. Horses can chow down now... and it will help the cattle too during the Artic Blast since they won't have to work as hard getting to the grasses.

It hit 52 degrees at my home in south Overland Park earlier this morning. The snow is gone except for the piles. I actually woke up around 1:30am because I heard water running through the downspouts. It was balmy. I just spoke on the phone with a friend who lives in downtown Milwaukee. They are presently receiving heavy snow and blowing snow with 8.5" of snow so far. They are expecting 3-5 more inches of snow before the storm quickly winds down early this afternoon. As I have contended on many occasions, I believe most of the metro is too far south to receive most major snowstorms that develop in the Midwest based on the typical path that these storms take and when, where they explode in development, exceptions duly noted, of course. Now for the next arctic blast. :^(

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

I think if anyone looks at our yearly snowfall average it is easy to conclude that snow in large amounts is not very common on KC.

Have a good day...

I have nothing to report but basically what (BOOTZ) had already said, roads aren't really that bad, and none of our snow is gone.  Now, when is the next time i can hopefully add to the snow on the ground? Jesse in Leavenworth

Even though I did not get a lot of snow the other day it looked like winter and was so pretty...well you would never even know it today. Not a sign of snow, frost or ice anywhere. The roads are all dry. Boo hoo!! The yards are wet but that is it. Sure hope mother nature comes through for a white Christmas. Have a great weekend everyone.
