Here are the snow maps for this weekend's snowfall. This is a case of cold sloshing down and waves of low pressure running along the fronts. Not until we can get the PNA to go positive can we get a storm to wind up despite the negative NAO. So with the PNA not positive, we will tend to see mean trough position in the Rockies and an up-and-down temperature pattern for the eastern part of the country.
Severe storms and snow mark the Memorial Day weekend.
Severe storms will hit the Northeast and western Texas today. Tornadoes could occur in Texas.
Severe weather for the Ohio Valley and Northeast today.
One more day of tornadoes, some which can be large and devastating.
Tornadoes could be worse today given the jet coming out into the Plains.
We are going into a five- to seven-day period of severe weather which will include tornadoes. We could see over 100 reports of tornadoes.
