Good morning bloggers,
It is already very cold this morning with temperatures in the single digits, but a major Arctic Blast will be arriving this weekend. The weather will be somewhat calm during the next day or so, and then we have two storm systems to track. The first one is smaller scale than the second one and we will discuss below. ARCTIC AIR WARNING! This next Arctic blast, the 14th or 15th one of the season, will arrive this weekend with the coldest morning likely around Tuesday. As you can see above the temperatures are forecast to get down to 30 or 40 degrees below zero in the United States. That excessively cold area is forecast to be across Montana and North Dakota. Kansas City Weather Time-Line:
- Today: 100% sunshine. Cold with west winds increasing just a bit to around 10 to 15 mph later today. High: 30°
- Tonight: The next cold front moves, but this one is not the Arctic Blast. Low: 12°
- Thursday: Mostly sunny and cold. High: 25°
- Friday: Mostly cloudy with a 70% chance of snow or sleet. Some accumulation is possible. High: 29°
- Saturday: Cloudy & very cold. There is a 40% chance of snow or sleet. High: 19°
- Saturday night-Sunday: Snow likely with accumulations possible. It’s still a bit early to pin down amounts. High Sunday: 13°
In-Depth Weather Discussion:
The California coast has been under the influence of a strong blocking pattern the entire winter season and as storm systems approach the west coast, they have been ripped apart by this ridge. A storm is now approaching California from the eastern Pacific and again this one is going to have a hard time getting through the ridge. You can also see the developing Polar Vortex. This is the 500 mb flow forecast valid this evening (around 18,000 feet above us).
By noon Thursday take a look at what happens to this first storm system. How this breaks through the ridge is important for our area because this is the energy that will be moving our way and affecting us on Friday. How will it get through the ridge, and then how will it evolve as it approaches Kansas City on Friday morning? The Friday storm will be a fast moving disturbance. The weekend storm is much slower, stronger, and broader.
Now, one more thing about this first system on Friday. It is a much smaller system, barely a storm at all as it passes by to our south. So, confidence on any precipitation and the type of precipitation will continue to be low all the way into Friday, I hate to say. We will have to watch it closely because it is on such a small scale. As this system moves by Friday the Arctic Blast will be approaching from the northwest. This will be a strong Arctic front and the strength of the Arctic air will likely have an influence on where the heavier winter precipitation sets up over the weekend.
We will update the blog later this afternoon or evening. In the mean time let us know if you have any questions or comments, and I will also be showing the overall weather pattern and how it relates to the LRC on the Weather 2020 blog by early this afternoon. Thank you so much for sharing in this weather experience. Remember the rules of the blog as the weather gets more exciting. Some of us get a bit emotional. No personal attacks will be allowed. And, please do not mention the competition by name, just saw another station or something like that. With all of the weather apps now a days we can get our weather information from so many sources. We will have our own forecast here and on 41 Action News. So, hang on, enjoy the ride, and let’s have some fun. Have a great day.
