Good late morning everyone,
We have been on a wild ride of weather during the past two weeks. I will go over what has happened, and what did happen to this storm system. We will try to add your snowfall totals to this list. First of all here are some of the snowfall totals we have received:
- Ridgeway, Mo: 10"
- St. Joseph, MO: 10"
- Platte City, MO: 7.0"
- Bethany, MO: 6.0"
- Lawrence, KS: 5.0"
- Kansas City, KS: 4.5"
- Cameron, MO: 4.0"
- Leavenworth, KS: 4.0"
- Edwardsville, KS: 3.0"
- Liberty, MO: 3.0"
- Overland Park, KS: 2.0"
- Olathe, KS: 2.0"
- Stilwell, KS: 1.0"
- Lee's Summit, MO: 1.0"
Our forecast was on the right track until we went into the day Tuesday. We should have gone with my motto from last week 1" to 4 and no more! Early in the morning it appeared to us that this storm was tracking a bit farther south, so we went for it. We brought the heavy snow band and put it right over Kansas City, but in the end it went farther north. So, the forecast was not perfect, but it did snow. When you are predicting snow, it is very different than predicting rain. Yesterday morning we had over 1 inch of rain in many areas. The day before we thought we could see around 1/2 inch of rain, but twice that amount fell. This would be like predicting 5 inches of snow but 12 inches happened. No one blinked an eye at the rain forecast. Snow forecasting is different and everyone demands a specific amount. In the end our forecast was really not that bad, it just shifted northward, right to where our original forecast was as of early yesterday morning. We will have to deal with the criticism, but I know deep down inside that we did quite well, but it just wasn't perfect and it did affect a few of you as a result. We will do our best to get the next one exactly right. And, we believe there will be a next one!
What went wrong with this one? Actually it is quite simple. Do you remember at 5, and 6 PM on NBC Action News when I was tracking that upper level spinning disturbance on our satellite movies coming across Oklahoma. During the late afternoon I tracked it and thought it would pass through Harrsisonville. It didn't it took off and raced right through Kansas City by 2 AM and went into northeastern Missouri where it spun around and died. My analysis of that disturbance was off and it brought in a dry slot and cut off the precipitation. It is really the #1 reason the snow ended up one county away. By 10 PM we realized this and made the correct adjustments to the forecast.
Let's look back before we look ahead. During the last two weeks here is what we have experienced. It has been a rather wild, frustrating, but fun ride:
- January 24th: 3 degrees below zero
- January 25th: Very light snow/freezing drizzle (no real problems at all)
- January 28th: 61 degrees
- January 29th: 55 at 6 AM, "mini blizzard" at noon with a crashing temperature to 10 degrees
- January 31st: Snow just misses Kansas City but 3-5 inches falls near Warrensburg, Clinton, and Sweet Springs
- February 3rd: Thunderstorms roll in with snow/sleet/hail/rain
- February 4th: 70 degrees
- February 5th-6th: Over 1 inch of rain (a record at KCI) and 1 to 8 inches of snow 2.4" at KCI, also a record for the date.
And, remember the LRC continues. The weather pattern is still cycling and will continue on around the 54 day cycle through the summer. So, we believe that there are more snow chances and wet storms in our future. More on the LRC and weather pattern later in the week. Let's first look at tomorrow as there is already another chance of snow.
Look below at the forecast for noon on Thursday:

This map, above is the 500 mb map (18,000 feet up). A fast moving upper level storm is racing by to our south and it is causing lift. You can see the vort max in Oklahoma (the X). And, look below at the band of moisture associated with this disturbance. We will have to watch this very carefully on Thursday morning for a quick band of snow.

And, then on the heals of this disturbance is an Arctic Blast that will bring us a glancing blow on Saturday. Look at the Arctic front forecast to be just north of us on Saturday morning.

We will be tracking all of these features on our newscasts beginning in a few minutes at 11 AM on NBC Action News Midday and then at 5,6, and 10 PM tonight.
Have a great day!
Gary and the NBC Action Weather Team
