Good morning bloggers,

I hope everyone is doing well on this Wednesday. The weather today may lift us all up today as we will make a run at 70 degrees. It has never been 70 degrees on December 9th in Kansas City's recorded history. The record high was set in 1897, or 123 years ago, when it reached 68°. Today's high temperature will likely come in at around 65°, but it could inch a bit higher. I will definitely be getting a noon walk in with Rainbow and Sunny.

We need the rain or snow. It has been quite dry since September 1st:

Rainfall amounts have been less than 50% of average for almost four months now. This is a dry weather pattern that has become established and when we have these chances of rain or snow, the pressure is on for these storm systems to over achieve. This fall, they have all been under achieving, in other words they have been producing low amounts of rain, and no snow since October. Well, rain and snow is in the forecast.

This water vapor satellite picture shows a storm spinning off the California coast. It already tracked across California from Nevada. When they move southwest, they come with very little moisture, and California only had a few sprinkles from this system. It is beginning to gather some moisture and it is about to make a move towards KC. I will be showing this tonight on 41 Action News, as I believe it will begin moving our way by later today.

By Saturday, as you can see above, there is a forecast from most of the models to have some rain, sleet, and snow in our viewing area. If this is a bit more organized, then some accumulation of snow is possible, but right now we have a few questions. Will it be cold enough, and how much precipitation will fall?

A surface storm, that L that I plotted on this map, will be tracking northeast Friday night and Saturday. Temperatures will be dropping into the 30s Friday afternoon, and by Saturday morning it may be down to close to freezing, or 32°. The temperatures are one factor, but how much precipitation falls is another. If it is only a tenth of an inch or less on Saturday, then we may see no accumulation to a dusting. Some models have been showing over 1/2 inch liquid, so let's see how these models trend.

Today looks great:

Let's take this one day at a time, and stop to smell the roses. Today will be a spectacular day, and Thursday looks pretty nice too. Let's see how close we get to the record high of 68°.

Thank you for spending a few minutes of your day reading the Action Weather Blog. We will go in-depth today and tonight on 41 Action News as the new data rolls in. Have a great day!
