Good morning bloggers,
The Arctic Blast Watch continues for this holiday weekend! A brutally cold air mass is developing and about to blast into the United States. We will look into this developing pattern and also discuss where we are in the LRC. An extremely dry stretch of weather continues over many areas of the United States, especially across parts of Kansas, Missouri, and over Southern California. Los Angeles has had an incredibly low 0.12″ since October 1st, when their rainy season begins. Last year 5.48″ had already fallen, and 3.82″ is average by now. This is 3% of the average rainfall so far in this early season. The driest year ever recorded in Los Angeles has been 3.38″. The majority of their rainy season is still ahead of them in January and February. Kansas City has also been extremely dry. I know last year I was concerned for a drought in the spring and summer, and those concerns are again very high. Last year, KC started getting hit by regular heavy rains once spring began. There is a chance of that happening again this year, but that chance is rather low.
This Cold Wave Is Right On The Cycling Pattern Schedule:
The second cycle of this years pattern is in progress now. Cycle #3 will begin in around two weeks, and we can hope that it will be more functional as there have been no major storms in KC in this second cycle. We will be looking into the third cycle soon. For today, let’s look at where we are now:
Today’s Weather Video
The latest models have this forecast valid on January 1, 2018 below. A 1052 mb (31.06″) surface high is settling in right over Omaha, NE:
Take a look closely, well, it isn’t that hard to see. The entire nation is pretty much dry as it will be controlled by this large and expansive high pressure area. There is snow over the shipping lanes off the east coast and a cold rain in the Gulf of Mexico. There is some weak Lake-Effect snow through the Great Lakes, but other than this the weather is dry nationwide, and cold:
Kansas City will likely drop to near 10 degrees below zero with the -20°F air reaching close to northern Missouri. This is just brutally cold. What is next? A huge warm up is likely before the Chiefs home playoff game on January 7th. Now, specifically for that day it is still unclear, but a rise to near 50 degrees or higher is likely between now and then as LRC Cycle 3 will be about to begin. For now, get ready for the Arctic Blast!
In the video, I showed the warm front from LRC Cycle 1 and discussed how something similar is happening now. Well, take a look:
Some warmer air will be approaching, but the Arctic air will then blast in Saturday. This map above is a forecast for noon on Friday.
