Stevo6899 Posted April 10, 2011 Share Posted April 10, 2011 Is the low going further north than expected? Thought the tornado threat was going to be further south into Illinois. Derechos likely to form further south? Link to comment Share on other sites More sharing options...
Jim Marusak Posted April 10, 2011 Share Posted April 10, 2011 btw, warnings to the northeast of red wing, mn. and TWC has one of their people (i think the same person that i saw yesterday at the skywarn workshop) over at Wisconsin Dells. and one other person that may be chasing some stuff today that may be a blast from the past on TWC: Declan Cannon (who's working at NWS-DLH currently).

Powerball Posted April 10, 2011 Share Posted April 10, 2011 Is the low going further north than expected? Thought the tornado threat was going to be further south into Illinois. Derechos likely to form further south? There won't be a derecho because the energy is expected to split with time. Since the energy is splitting the best dynamics is displaced further north than what was expected a day or two ago, thus making it harder to break the cap for areas in between and somewhat decreasing the severe weather potential. The storms that develop in Wisconsin will move up into Northern Lower Michigan and the UP. The other part of the energy is expected to spawn more thunderstorms in the central/southern mississippi valley that will move E/NE. Link to comment Share on other sites More sharing options...

I think you're talking about Julie Martin down in Rockford; they showed a map of the Dells when I turned the channel on, but then found out she was in Rockford. Unless they have another met in the Dells. Link to comment Share on other sites More sharing options...

wisconsinwx Posted April 10, 2011 Share Posted April 10, 2011 How is the cloud structure? Does it look convective? It's a cross between white and blue. It's probably just the sprinkles, but I didn't think instability sprinkles would come with much overcast. Link to comment Share on other sites More sharing options...
thewxmann Posted April 10, 2011 Share Posted April 10, 2011 cells in northeast IA look like they are still struggling against the cap. storms north of that area look a bit better.
