Good morning bloggers,
Things to think about today:
- We experienced another cold blast with a huge temperature crash and temperatures made a run at zero this morning.
- The strongest Arctic blast of the season will likely arrive on Wednesday
- A MAJOR SHIFT in the weather pattern is right on schedule, according to the LRC, within 10 days as the active and more stormy part of our weather pattern is not that far away
- Kansas City is on the edge of an extremely dry winter weather pattern, but amazingly we have two phases to this weather pattern one of which is rather wet and due in within weeks.
That was one cold blast yesterday and the low dropped to 4 degrees above zero this morning at KCI. For at least the 6th time this season we had dramatic temperature crash, or temperature rise. If you remember on Christmas Day it was 10 degrees in the morning and Kansas City had 2 inches on the ground for a white Christmas. By December 26th it warmed up to 66 degrees for a 56 degree rise. These ups and downs will continue as it is one of the distinguishing characteristics of this years LRC in our part of the nation. Remember the LRC isn't just a cycling weather pattern that is repeating over and over again. The "long term" longwave troughs and ridges produce similar set ups through the entire weather pattern, so these big temperature swings will continue through winter and likely through spring!
A warm front is approaching and will likely move through this evening, which is fascinating as the temperatures have dropped into the single digits this morning. As the warm front passes, associated with the next Alberta clipper, we will see temperatures rise tonight into early Wednesday, but then the Arctic front with this next clipper will likely be the strongest front of the season thus far and is due in before noon on Wednesday.
And, it is extremely dry over Oklahoma, North Texas, into the panhandles and western Kansas over the winter wheat fields. Gage, OK has had 0.08" of precipitation since November 1st. Oklahoma City is around 25 % of their average since the same date. We are right on the edge of this dryness, but the stormy and wetter part of this years weather pattern is going to return. We will likely have enough moisture here, but will it hit areas to our south and west?
We are in the part of the pattern where ridging is inland over western Canada. During the winter it is extremely difficult for a ridge to stay over land due to the land sea temperature contrasts. The ridge will try to retrogress to off the west coast and this just sets the stage for the next phase of the weather pattern. Look at the map below:

When there is a ridge inland at this time of the year you can almost count on a big trough in the same spot within days. And, the GFS and ECMWF have a strong developing trough over the western United States just days after this map, and yes this is what is suppose to happen according to the LRC. The next chance of a storm is from the part of the pattern that ignites the exciting and stormier phase of our weather pattern, which happened around November 30th. So, given the 50 to 53 day cycle we should expect a significant storm in the plains by January 23rd.
I will add a blog on the approaching changes later this evening. Watch NBC Action News as we track this next Arctic blast and all of these changes. Jeremy Nelson is still filling in for Brett and he will keep you updated through the morning. Jeff Penner and I will be working on some special graphics to explain this amazing weather pattern at 5, 6, and 10 PM tonight.
