As you've probably already seen, we are expecting severe thunderstorms across much of our area today. There are still some questions about how things will come together, and there will have to be some fairly significant changes in the atmosphere (moisture return being the big thing) for things to get going. However, many of the ingredients we look for for significant severe storms will be in place by this afternoon.
While we have not formally upgraded to a moderate risk, we have highlighted an area where we expect to see an enhanced threat of supercells into the evening. This will change through the day as we track the exact placement of boundaries, most unstable air, and the expected surge of richer moisture into the area.
We will continue to provide multimedia briefings through the day and into the evening, and we hope to be able to do more frequent briefings as the event unfolds. During last week's severe weather event, we managed to do a new briefing about every 20-30 minutes. We'll see what happens today.
Keep an eye on our enhanced page for more details.
