If you are watching what is going on the pattern currently, it is what I believe will eventually lead into the overall winter pattern. We are have troughs moving into the Great Lakes, and that is leading to chilly weather while the southern branch remains active with storms cutting under the troughs and eventually phasing to produce storms. In a few months, a pattern like this would lead to a lot of snow for many folks from the Midwest to the New England.
I added a map showing the highlights this week. Miriam is probably going to be a big rain maker for the parts of the Southwest into Texas and could end up being a rain maker all the way to the East coast. There are some disagreements between the GFS and Euro on the eventual movement of Miriam into the U.S. I am leaning more toward the Euro showing the system coming out an entity and not a system that gets broken into pieces as per the GFS.
The other highlight will be the heavy storms along the front. The front will sag south the next couple of days and that could lead to storms developing along the front which may have hail. It's getting cold aloft now to hail storms will become a little more common now.
It's going to be a stormy period across the country, but the models seem to differ on the outcome.
The storm that is coming into the Plains will produce a wide range of weather including snow, ice and flooding rains.
The holiday time will be stormy in the Plains and Front Range of the Rockies. Travel will be impacted by the weather.
A swath of moderate to heavy snow to move from the Midwest through the Great Lakes.
A storm will streak out of the Rockies into the Great Lakes producing a swath of a snow along its path.
