Good evening everyone,
Very interesting data tonight! We continue to analyze all of the models coming in, and I will have more including our snowfall forecast in this blog right after the newscast.
A strong storm is heading our way. Colder air is moving back in after it hit 70 degrees in Kansas City this afternoon. There are some concerns for Tuesday:
- 1. Will it drop to below freezing during the day on Tuesday. If it does, then freezing rain could become a serious problem.
- 2. When will it be cold enough to snow? When will the precipitation changeover to sleet?
- 3. Where will this storm track at 500 mb?
- 4. How long will the precipitation last into early Wednesday?
My first observation, after looking at the NGM and NAM tonight, tells me that this is very similar to other storm systems we have had this season. The NAM even predicts a precipitation pattern that happened with one of the bigger storm systems of the season where 8 to 9 inches fell northwest of Kansas City. There is a cold surge of air coming down across Nebraska, and if this storm is going to track farther south, then this cold air will push everything southward. Just a little bit and KC is in this thing. I am still thinking 1 foot of snow is likely somewhere, but the northwest corner of Missouri is the targeted area at this time.
The GFS was even worse (or better if you don't want any snow) than the NAM. I will have my update in a few minutes. We will see how it looks in the morning. And, I will add our snowfall forecast map to this at 10:30 PM. Here is the map! And, everyone, this very well may track farther south. So, let's just be patient and see what we think by morning.
