Powerball Posted May 29, 2011 Share Posted May 29, 2011 I wasn't expecting that covection ahead of the MCS. That's a bit of a concern. Link to comment Share on other sites More sharing options...
kab2791 Posted May 29, 2011 Share Posted May 29, 2011 Good luck everyone chasing. Hope to see some well-structured shelf-cloud pics. I will be doing the same thing, west of 47 and north of 30 is usually a pretty good spot. Link to comment Share on other sites More sharing options...
Thundersnow12 Posted May 29, 2011 Share Posted May 29, 2011 wish those storms from south of DVN to LaSalle/Peru weren't there. Link to comment Share on other sites More sharing options...
Powerball Posted May 29, 2011 Share Posted May 29, 2011 We already have 8 severe weather reports, 5 of which are hail and 3 of which are wind. EDIT: And the numbers are growing as I type, lol. Link to comment Share on other sites More sharing options...
janetjanet998 Posted May 29, 2011 Share Posted May 29, 2011 wish those storms from south of DVN to LaSalle/Peru weren't there. warm advection wing of the MCS very common...south of them is the warm sector... sometimes you get spin ups in those..but I would target the bow head which should move along I-80 Link to comment Share on other sites More sharing options...

I'm going to gas up now so I don't have to later when this thing sucker gets closer. Link to comment Share on other sites More sharing options...
cyclone77 Posted May 29, 2011 Share Posted May 29, 2011 Thundering, foggy, and very still here. Sort of spooky in a way. Very dark outside. Not gonna chase this. Probably just stay right here and watch it come in. Link to comment Share on other sites More sharing options...

A-L-E-K Posted May 29, 2011 Share Posted May 29, 2011 downright cold here with fog getting more intense. Some of the oddest pre-severe wx conditions i can recall, can't help but be a little skeptical of the threat lakeside. storms on WAA wing rapidly building into Chicago Link to comment Share on other sites More sharing options...
Powerball Posted May 29, 2011 Share Posted May 29, 2011 SEMI style convective cloud debris? On the contrary, other than some passive stratus for 15 minutes around 9 AM we've had full sunshine here. I suspect the stratus to the west will mix out too. I don't care if debris comes in anytime after 1:30 PM (peak heating). The damage WRT destabilization will already be done.

Powerball Posted May 29, 2011 Share Posted May 29, 2011 Abuot the only model picking up on this MCS is the HRRR. The NAM is clueless as usual (granted it does have a nice MCV moving through today, I'll give it credit for that). Link to comment Share on other sites More sharing options...
A-L-E-K Posted May 29, 2011 Share Posted May 29, 2011 12z NAM misses this whole complex LOL and RUC playing catch up absolutely nothing new there, although it hinted hard at the potential 48 hrs out WAA wing really lighting up now. Link to comment Share on other sites More sharing options...

cyclone77 Posted May 29, 2011 Share Posted May 29, 2011 DVN toned down the wording on their new warning that includes the QC. Really not seeing anything all that impressive on velocity scans right now. Winds look marginally severe at this point all along the line, but that could change very quickly. The lack of surface based instability may be keeping this thing from going completely crazy at this point. Link to comment Share on other sites More sharing options...

kevlon62 Posted May 29, 2011 Share Posted May 29, 2011 I will be doing the same thing, west of 47 and north of 30 is usually a pretty good spot. Had a very nice horizon view at the east end of KARR a few weeks ago. Basically parked/sat on the paved side of a curb cut on the new Municipal Drive/Galena Blvd. watching a few planes skim over on their final approach from the east into 09/27. Air & ground ops provided for some light diversion during the wait for storms to roll in. Might make the move south today. Looks like WAA wing and instability gradient is helping to set stage for some NE movement. Link to comment Share on other sites More sharing options...
janetjanet998 Posted May 29, 2011 Share Posted May 29, 2011 absolutely nothing new there, although it hinted hard at the potential 48 hrs out WAA wing really lighting up now. its possible the bow part of the system may turn a little ESE over N IL...and you will be stuck in both the WAA heavy rains and the north end of the bow heavy rains if other words heavy rains for 2-3 hours Link to comment Share on other sites More sharing options...
hawkeye_wx Posted May 29, 2011 Share Posted May 29, 2011 There were a couple reports of 50-60 mph wind just south and just ne of Cedar Rapids, but I barely got any wind at all. I just got about 0.40" of rain with some garden variety lightning/thunder. Update: It's now getting much breezier in the wake. Link to comment Share on other sites More sharing options...

Winds look marginally severe at this point all along the line, but that could change very quickly. The lack of surface based instability may be keeping this thing from going completely crazy at this point. DCAPE is pretty weak out there but increases somewhat east and south and is being injected north pretty quick. I doubt we see anything too wild, but as the cold pool grows, we'll probably see some 70 mph gusts today. EDIT: filtered sun Link to comment Share on other sites More sharing options...

cyclone77 Posted May 29, 2011 Share Posted May 29, 2011 A lot of CG strikes around here right now with this WAA wing crap. Hope it doesn't knock my power out before the line hits. Link to comment Share on other sites More sharing options...

outflow Posted May 29, 2011 Share Posted May 29, 2011 i think your too far north, i see the whole system moving straight east, maybe even ese, into the greatest instablity, but it will be a close call. Link to comment Share on other sites More sharing options...
cyclone77 Posted May 29, 2011 Share Posted May 29, 2011 Torrential downpour with lots of CGs and dense fog lol. Fun times. Looks like Tipton just got hit by some pretty strong winds according to the latest few velocity scans. Link to comment Share on other sites More sharing options...
wisconsinwx Posted May 29, 2011 Share Posted May 29, 2011 We'll get in on some rain and embedded t'storms, but that's about it. Tuesday looks like the better potential overall; already 15% hatched for SE Wisconsin. Link to comment Share on other sites More sharing options...
SEMIweather Posted May 29, 2011 Share Posted May 29, 2011 DTX issued a flood watch for the southern 4 tiers of counties. Can't say I'm surprised considering how much rain we've gotten over the past 2 weeks. Link to comment Share on other sites More sharing options...
