Fast, Mild Zonal Flow to Continue Through Current Forecast Period

Lead Forecaster Daniel Crawley

Good Monday morning to everyone,

The weather across the United States is in a rut. A very fast zonal (west to east) flow is dominating the weather from coast to coast.

Water Vapor (Pacific Basin)

Looking at the water vapor image above ☝️, a long line of storm systems are slamming into the West Coast of the United States. The state of California has been hit particularly hard in recent times with heavy rainfall and mountain snow measured in feet.

The Pacific jet, which at times has reached as fast as 180 knots, has overtaken the entire weather pattern for the US preventing any buckles to push cold air in from the north.

The effects here in North Carolina is a rapid flow in which shortwaves move across about every three days. Some are stronger than others but nearly all of them are bringing rounds of liquid precipitation to the Carolinas.

Unfortunately there seems to be no indicator of this ending inside of the next 10-14 days. More systems will move across and brings rounds of precipitation but for snow lovers it’s bad luck.

Northern Hemisphere 500 mb winds

Fingers are crossed 🤞 that by the end of the month the Pacific Jet will relax just enough to where things will re-arrange itself again to where cold air can get back into the pattern.

Here is a look at rainfall potential over the next seven days. The bulk of this might come with this Fridays system.
