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.
Heavy snow and even thundersnow coming Northeast tonight. More ice and snow Sunday.
Damaging ice storm on the way for the lower Mississippi Valley. Another storm will bring more snow and ice problems this weekend.
A cold and wintry weather pattern setting up prior to the Holidays.
Cold air spreads out across much of the country and leads to a battle ground of snow and ice in the East.
Lake snows will be heavy in some of the traditional NW flow locations.
