Good morning Weather2020 bloggers,
I just went out and checked my rain gauge for the first time since this storm started. Here on the south side of the KC metro area in Overland Park, I have had 3.72″ of rain. Wow! Some of that was in the form of freezing rain. What a storm! If you have a rainfall total for the storm, please let us know.
A storm closed of and then cut-off from the main jet stream a few days ago, and it is still sitting over the western United States this morning. Can you see the center of this upper low over the Utah/Nevada border. Look closely and you can see the spin on this water vapor image. It is actually a broad stretched out upper low, and it is now going through the beginning of a major transition.
This system is now beginning to make a move to the east. It will redevelop as it moves over the Rocky Mountains and out over the plains states on Monday. It has been producing record amounts of rain for this time of the year, some ice, and some snow. Kansas City just had two days with some icing, but temperatures this morning have risen to just above freezing and most of the ice has melted.
Take a look at these two radar images this morning. The top one shows the band of rain showers extending from western Illinois to northern Oklahoma, and the second one shows the precipitation type:
The overall weather pattern is featuring a split flow with a northern branch way up across Canada and the southern branch around the upper low over the southern United States. After this upper low kicks out into the plains the flow aloft is forecast to somewhat come back together again, but the indications continue to point in the warm direction, as discussed in our preliminary winter forecast:
We continue to learn more about this cycling pattern. We will release our in-depth winter forecast discussion later in the week. Have a great Sunday and thank you for participating in the LRC Forecast Experience Blog!
