Good late afternoon bloggers,
Updated at 5:55 PM: We have a special snowfall accumulation map made for the 6 PM newscast on NBC Action News. If the storm approaching becomes organized and stronger there will be more snow north and even less snow south. But, there is a trend for it to be more disorganized. Let me show you what I mean:
Below is the 500 mb forecast valid at midnight Wednesday night by the NAM. Notice the closed circle over northwest Kansas. WE DON'T WANT THIS TO HAPPEN (if you want more snow). But, look at the afternoon NAM on the second map..

This second map is also valid at midnight Wednesday night. Notice that there is no close circulation. A weaker, more positively tilted storm will lead to a faster cold front and a changeover to snow earlier. We don't want this storm to intensify. If it does the dry slot will move in faster. There is a very strong frontal zone that will slowly move across Wednesday night. Heavy precipitation will likely form in this zone. There are a lot of other factors and we will discuss these later on this evening. So, vote for the second solution below, if you want snow. We will have an update later this evening.

I have no doubt that part of the viewing area will have significant snow accumulations. And, part may have very little, once again. This makes it very difficult for our weather team. But, we will figure this out tonight. Be sure to watch NBC Action News tonight at 5, 6, and 10 PM. We will update the blog around 6:30 PM. The afternoon data has some more warning signs and we are analyzing them.
