First inch of '11-'12 Winter

Our first inch of snow came through Monday night, and took most everybody here by surprise.  By 5:00 am, we had nearly half an inch on the ground and roads, which made it a slick drive to work.  Snow fell steadily throughout the day, albeit in spurts between light snow and flurries.  When the day was done, and after a bit of melting, we ended up with 1".  Only missed that date by three days this year! 

Calling for light snow tonight.  I'm looking for a birthday snow!

First possible accumulating snow

The snow contest board is up in the teacher workroom, and I feel good about my predictions this year.  We try to predict the first accumulating snow (>T), first snow day, and total amount for the season.  Here are this year's predictions:

First Accumulating:  Dec. 3
First Snow Day:  Dec. 9
Total Snow:  28.5"

It's funny to see how last year's 54" of snow affected everyone's predictions for this year.  There are a lot of guesses in the 30s and 40s!  That's an Oshkosh winter.

NBC Action News Weather Blog is showing a chance for snow this Saturday (the 3rd!), which could be the first for many in Missouri.  I'm getting excited and am ready for the season to start.

What????

Surprise!!  March 14 was supposed to be the beginning of our spring break, but our blizzard break from Jan. 31 - Feb 4 wiped all those day away.  No complaints here, though.  Much to our amazement, and the meteorological network's surprise, we were graced with another nice snowstorm!  Forecasted to bring our area <1", we ended up with a total of 9.1" at this station.  This brings our seasonal total to 51.2". 

The snow fell as very large conglomerate flakes during much of the day.  It was amazing.  A co-worker said it reminded her of spring in Colorado.

World Sunlight Map

In my research I often find some pretty interesting resources. I thought I'd share with anyone here who might find this interesting as well.

Exploding Snow

Found this video on another blog. I've seen some big ice chunks come off 18-wheelers, but never anything this bad.

Blizzard '11 - February 1

7:30 p.m.

The wrap around moisture from the storm has come and gone in a hurry.  We experienced a short time with moderate snowfall and light winds as the low pressure system traveled nearby.  Now that it is on its way to the NE, we are officially on the back side of the storm and into the 3rd phase, windy and bitterly cold.

My final observation was at 7:05, bringing the storm total to 16.0".  This is of course assuming we don't experience any more wrap around moisture. 

Here are my final snowfall observations (pending any additional snow tonight)



Snowfall rates started off light but quickly became incredibly intense.  By the 10:00 hour, we were pushing 2.0"/hr and many places were reporting the same.  I read a few reports in areas north and west of here experiencing thundersnow, but didn't hear any today. 

Storm average snowfall rate from the period of 5:30 am to 7:30 pm:  1.14"/hr

2:30 p.m.

I could only imagine what a blizzard looks like, and what I'm seeing now is the image I've had.  But I never realized what a blizzard feels like.  It kinda puts your senses on edge.  Our winds are now sustained at 23 mph and gusting 35-40.  I feel like something could give at any time.  And that makes me nervous.

12:05 p.m.  |  7.5"
1:05 p.m.  |  8.5"
2:05 p.m.  |  10.0"

______________________________

11:30 a.m.

At midday, snow has been falling for 6 hours.  Moderate snow has been the norm with periods of heavy snow.  At the most, we have had 2"/hr rates.  Snow is getting difficult to measure, so I've had to start taking multiple measurements.  Here are the 2 observations I've taken since last observation:

10:05 a.m.  |  4.0"
11:05 a.m.  |  5.7"

Our power went out for a minute or two a little while ago.  It made the sober reality set in for my wife and I.  There are reports of power outages since 10:30 just south of Mexico (25 min north of here).

______________________________

9:05 a.m.

Snow started falling this morning around 5:30, and increased in intensity very rapidly.  Moderate and heavy at times, the snow quickly covered the ground.  Winds have been light at times and brisk at others, nothing extreme yet.

Total Snow:  2.0"


This video shows our current snowfall rates, as of 9:05 a.m.

Blizzard '11 - January 31

A historic event is expected to unfold in mid-Missouri, and in fact in most of Missouri tomorrow and Wednesday.  Having grown up in Missouri, I have seen snow storms come and go.  Most of the 'big' storms have been such that provided a nice blanket of 6-10" (as we just experienced on the 20-21st), and I can count on one hand the times we have had extreme snowfalls of 12-15".  Nothing comes close to what has been churning for the past few days, and what may possibly come through in the next 12 hours. 

The Setup

A split flow in the jet stream has merged dropping down a large polar air mass that is expected to bring sub-zero temperatures by Wednesday night.  At the same time, a huge storm will be ejected out of Texas bringing an enormous amount of moisture tapped from the gulf.  Below is a graphic showing the projected path of the surface low that will cause this storm.



Here is the 2-day Quantitative Precipitation Forecast valid Monday night:


These amounts are extreme, even during spring torrents that visit the area.  But to have a snowstorm bring such rain is unprecedented during this generation.

On the right side of my blog, I show the NWS STL graphical snow forecast.  This changes with each cycle of the model runs, and this image was captured at 6:00 am Tuesday morning.  Amazing totals.





Finally, a first has happened in the history of the NWS STL.  Never before have they issued a Blizzard Warning for their CFA.  As you can see below, much of Missouri is under a blizzard warning from 6 am Tuesday till noon Wednesday.  Blizzard conditions include heavy snow, 35+ mph sustained winds, and 1/4 mile visibility for at least 3 hours.




Of course, this storm is not affecting only our area.  Many people will be affected by this dangerous system across the country.  A crippling ice storm is expected for southern Illinois into Indiana, and the heavy snow will continue northeastward into the already battered New England states.  The warning map below was captured early this afternoon.

January 10-11 Snow

Snow fell again in mid-Missouri, and it's a beautiful sight.  Around 11:00 am, light snow began to fall, and throughout the day, we experienced steady moderate snowfall, tapering to light snow by evening and finally ending around 3:00 a.m.  This morning, the 11th, we have frigid air spilling in.  Currently it is 12° with a wind chill reading around 5.
