1. Isaac will take most of the day and night to track into western Louisiana, so the flooding and damaging winds will continue through the night across eastern Louisiana. It will take until tomorrow before the weather calms down across the area.
2. Our attention turns to the path of Isaac through the Mississippi Valley into the Ohio Valley. I expect to see flash flooding along the path of Isaac despite the fact that the rains will be welcome for many farmers suffering from the dry summer.
3. Typically, warm core tropical systems will get pop-up thunderstorms during the night and that's when the flash flooding will occur. So during the day we have scattered showers and thunderstorms then at night, storms develop near the center of the path of Isaac, and during that time you can get intense rainfall and flash flooding into the morning hours.
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.
Latest map on the severe weather areas this weekend into Monday. Monday could be the big day.
Marginal severe weather the rest of the week, but the weekend could turn ugly in the Plains as the tornadoes return.
