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.
At least two areas of heavy rains through this weekend may result in flooding problems.
Heat and Humidity will attack the trough and result in heavy rains and heavy thunderstorms.
Severe storms will develop across New England this afternoon and may produce damaging winds and even another tornado.
A busy weekend for the Midwest and Ohio Valley as severe storms will hit ahead of the cold front.
Severe weather will rip across the Northern Plains today. Parts of Canada may see tornadoes.
Severe weather will be the focus the next couple of days. Tornadoes may hit western Canada.
