1. Winter is going to wind down by next weekend as the pattern is going to change to a warmer one, which will be more like a March weather pattern, just coming earlier. What this means, instead of having prolonged periods of extreme cold, we will get waves of cold followed by periods of mild weather. In addition, you can still have snowstorms, some of which can be heavy. It's the type of pattern where it snows 6 inches one day and two days later it's in the 60s.
As for the spring and summer, if we start seeing the heat build in the Plains, especially the northern Plains, get ready for the heatwaves to build in.
2. As for the end-of-the-week storm, with the NAO not going negative and the first storm building the vortex across eastern Canada, it looks more likely that we will have a storm that cuts across the southern Plains and out across the Carolinas and not one that comes up the coast. I really thought with the pattern changing, a big storm would come out of the pattern, but it appears the pattern change will occur in a wimpy way and not an exciting, big-bang-of-a-storm way.
3. The map below is for the storm coming. It's very much like the storm that just occurred with snows coming up from the southern Plains into the Northeast.
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.
