The Siberian Express is going to set up across the United States.
What is the Siberian Express?
It is when air from Siberia itself comes down into the United States. It creates cold air for a lot of the United States. The Climate Prediction Center has issued images on what the Siberian Express will look like this time around. Images are below.
The first two images are days 6-10. The first one is precipitation, and second one is temperature.
(Green- above normal precipitation. Brown- Below normal.)
(Blue- Below Normal temps. Brown- Above normal temps.
The Siberian Express, while short, may have significant effects on the general North US in terms of precipitation, while the entire US will be affected in the way of colder temperatures.
