Meso for Iowa
June 22nd, 2010 at 8:48 pm by Bill Steffen under Bill's Blog, Weather
<–I think that’s the biggest meso-discussion that I’ve ever seen. Click on the image to read the discussion. There are strong thunderstorms getting together in Western Nebraska (four tornadoes). and others coming north out of Kansas. Storms also firing in Iowa. They say: “…A large mesoscale convective system appears possible…capable of producing widespread damaging winds and hail.” They have a tornado on the ground at Sac County Airport in Iowa. In the next few hours we’ll see if this can all come together and start the trip east to Michigan. MORE: SPC says: “Genesis of a derecho-type damaging wind event!” SIDE NOTE: The day before the ’98 derecho: temperatures in the mid 80′s, mostly sunny (70% sun) and relatively light winds (average speed 7.5 mph). Sounds like Monday’s weather. We have a strong SW wind tomorrow PM. At 11 PM, the temperature dewpoint at Des Moines was 85/75 and at St. Louis it was 86/77. That’s pretty humid air – it’s going to be warm and muggy Tues. PM.
HERB I see a long train coming a 5 state train with tornado warnings again!
i bet some thundershowers, all day clouds and low 80′s if that. unless proven otherwise this will be another bust. oh well at least we had last night. i hate hype and you guys had to know things would change in a 24hr period. long range severe outlooks are junk science just as 8 day forecasts are. night all, cant wait too see the whiners on here when i wake up.
Awww common fixx, your not sticking around for the 2am party?
see some more red in wisc!!!!
Go to the Lacrosse Wi radar.
Wonder if these will have the lightning like the storms monday night did

CHASING TODAY LOOKS LIKELY!! STILL IN THE MODERATE YEEAAAAA: http://www.spc.noaa.gov/products/outlook/day1otlk.html
wow!!!! that outlook looks impressive.. im a bit surprised actually.. we shouldnt be iun the moderate risk…. 10% chance of tornados!!!!!!!!!!!!!
College of Du Page comes out a bit quicker than SPC, here is SPC

the first line wont be severe. i think there banking on storms later in the day. we shall see how warm it gets tomorrow. night guys
is it true that this line won’t be severe? anyone clarify that please..
Because there isn’t a moderate risk for severe weather, with a powerhouse of a storm, with t-storm, tornado, and flash flood warnings associated with it or anything. If you’re from Holland, you know what last year’s flood was like, and you should be able to figure this out.
What do you mean there isn’t a moderate risk for severe weather, we are still in the moderate risk area as of the latest update.
I give up on sarcasm. All things point towards severe storms.
Sorry, I don’t catch sarcasm on the interwebs quickly at 2am in the morning.
ASED ON THE EXPECTED TIMING/LOCATION OF THIS MORNINGS
ACTIVITY…OBSERVATIONAL/NUMERICAL GUIDANCE EVIDENCE SUGGEST THE
MCS-DOWNSTREAM EASTERN-SOUTHERN PERIPHERAL AIRMASS SHOULD HAVE
OPPORTUNITY TO DESTABILIZE RELATIVELY EARLY IN THE DAY ACROSS
NORTHERN PORTIONS OF IL/INDIANA INTO LOWER MI/NORTHERN OH. THIS MAY
YIELD A SUSTAINED WIND DAMAGE THREAT THROUGH THE MORNING AND/OR
CONTRIBUTE TO A RENEWED SEVERE POTENTIAL IN THESE AREAS BY EARLY
AFTERNOON. WIND DAMAGE WILL LIKELY BE THE PRIMARY CONCERN. SOME
SEVERE HAIL WILL BE POSSIBLE…AND PENDING A SEMI-DISCRETE
SUPERCELLULAR MODE AWAY FROM THE EARLY DAY MCS…SOME TORNADOES WILL
BE POSSIBLE AS WELL.
That I do believe is why we are still in the moderate risk Tim
tornado watches out for wisconsin!
getting to be a very colorfull map this early am ..

Did everyone go to bed? My 2 year old just woke me up at 3:30..an hour later we are still sitting up. Not sure if I will go back to bed now, I am sure the other kids will wake me up soon according to the latest radar.
Look at those colors coming over the lake!!!! GR, looks like you will be hit with VERy heavy rain and possibly some hail.
Looking at the base velocity NWS radar does that look like a water spout just off Milwaukee?
I was thinking no, but comparing with other radars, it looks like it could be
according to TWC… southern michigan has a 60% chance of seeing a tornado within a 50 mile radius, and that is the only fairly accurate part of TWC, and im not just saying that b/c of the situation we are in either

starting to look interesting
