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.
Temperatures will be swinging around but the warmth will end up winning.
Heavy storms will hit parts of New Mexico and western Texas.
Heavy storms will hit parts of New Mexico with heavy rains and gusty winds.
The band of heavy rains should end tonight, allowing drier weather to move in.
Heavy rains associated with the upper-level low will hit the Carolinas into Virginia. Some areas could get over a foot of rain by Monday!
The heavy rains are still coming and someone is going to have up to a foot of rain and flooding.
