Good morning bloggers,
This is not a great week for us in the NBC Action News Forecast Center. Overnight, the thunderstorms fell apart. We have had a few sprinkles and light rain showers. And, now many areas will likely miss this next storm as it produces a deluge of rain over southern Kansas and southern Missouri. This is like one of our snowstorms that also missed us to the south. When you are on the northern edge, trying to pick out how far north the rain shield will be, the northern edge of a developing comma head, is one of the toughest forecasts to make. If you pick it out exactly right, then you will know who will get no rain at all, and who will have 5 inches of rain or more. Our latest in house computer model is predicting 6 inches of rain in Clinton, MO later today and tonight, and 0.04" at KCI airport.
I know we had a snowstorm like this, that ended up making us look like fools (I just checked and I believe this is directly related to the January 31st storm, or 98 days ago. The same thing happened and it tracked south of us, and I was even making some similar statements, so I could have used the LRC and pegged this rainfall pattern). Try not to bash us if the rain misses your location. Remember, we already feel pretty bad about this forecast as we continue to wait for our first real good rain shower of the week. Confidence is still low on where the northern edge of this storm will track. Right now, I lean with our in-house computer model keeping most of the rain south of I-70. So, if this is the case, then one knotch farther south and there will be no rain at all today. One slight shift to the north and we will be in the heavy rain.
Look below at the forecast track of the upper low:

So, based on this forecast, north of the blue line would get no measurable rain today. Once again, just an extremely slight shift northward and we would be in the comma head.
As soon as I see more evidence of the comma head developing, we will update the blog. Right now, it looks dry through most of the morning and this is two days in a row where our rainfall forecast would have been way off, for now.
