The pattern for the next two weeks will be very stormy. In addition, the NAO is finally going negative and the PNA is going positive. I find it interesting that the NAO values are getting close to the values we saw around the time of Sandy. If that is correct, we need to watch the East coast for possible big storm.
In the meantime, I have maps showing what to expect with the first in a series of storms. This will be a sloppy storm with some front end wintry mix and back end rain changing to snow.
Thunderstorms across the lower Mississippi could get severe this evening with wind damage and hail. I think a more widespread severe weather event will occur with the second storm across the South Wednesday into Friday.
That second storm will also produce a blizzard in Nebraska and Kansas and snow into the Ohio Valley before it dwindles out.
The GFS suggests that a wave of low pressure forms this weekend and hits the Northeast with snow. With the blocking in place, we need to watch that storm for heavy snow in the Northeast this week if indeed it occurs.
A storm will move out of the Rockies this weekend and move east. It will produce a band of heavy rains.
The High Plains will remain active with severe storms today.
A cold front moving across the Northeast will produce severe storms. The High Plains will also have severe storms and maybe tornadoes.
The bulk of the severe storms will stay on the High Plains today and Tuesday.
Severe weather will hit the Upper Midwest and southern Canada. It could be a tornado day!
Another big day for severe weather. Damaging winds and even a few tornadoes possible today.
