1/13/05 FCST: Deep South and Great Lakes

The SPC has issued a slight risk for the deep south states of LA, MS AND AL for severe weather.

Yes, talk about a MI-Wishcaster, which I can be at times - but the SPC has given southeast lower Michigan a 5% risk for damaging winds, along with the rest of the Ohio Valley. Can anybody shed some light on this situation also?

The wind fields across the Great Lakes will increase dramatically to nearly 60-70KNTS in the first 3K feet of the atmosphere. Combine this with the very strong forcing around 12-1800Z, and you got a favorable setup for a few thunderless damaging wind events... Not really a big deal at this point (thus no SLGT risk).

Of note: Earlier this afternoon, there was some pretty impressive storms (for Jan.) near GRR with 55DBz cores -- Most likely small hail producers, and since they were thunderstorms, with higher echo tops -- I would rule out sleet. Still interesting though, because OBS showed temperatures in the mid 30's attm.
 
Actually L2 data showed a 68.5dbZ return just on the north side of GRR! Same agreement - looks like gusty winds and/or small hail could be an issue but nothing that exciting.
