Merry Christmas: Snow Moves Into Saturday’s Forecast

Merry Christmas Bloggers,

A strong storm is developing over the southwestern United States today. Snow levels are dropping over Southern California, and as this storm ejects out into the plains states, a major snow storm is likely over parts of the northern and central plains.

This map above shows the strong surface cyclone located near Omaha, NE on Thursday evening.  Warmer air will surge north on south winds ahead of the storm, and some big thunderstorms are likely over Tennessee extending south to the Louisiana and Mississippi Gulf of Mexico coast.  Near blizzard conditions are possible farther north, and then a cold blast will arrive in Kansas City Thursday night. This cold air will be in place for a weaker storm system that is directly related to the part of the cycling pattern that produced the end to our snowflake contest on November 12th. An inch of snow again is possible on Saturday with this second cycle version of this pattern.

This smaller system will zip across the southern and central plains on Saturday.  Most of the models have trended in the direction of some small accumulation of snow, and even an inch or two near KC.  We upped the chance of snow to 50% as it fits the LRC well.  It isn’t a wet and strong storm, so it makes this still a forecast that we will gain confidence on in the next 24 hours as it is only four days away.

There are also strong indications of a much colder and blocky pattern developing in the next two weeks.  We will discuss these trends in the blog the rest of the week.

Happy holidays, Merry Christmas, and have a great day!  Thank you for spending a few minutes of your day reading the Action Weather Blog featuring Weather2020 and the LRC.
