wisconsinwx Posted September 5, 2012 Share Posted September 5, 2012 I'm going to guess winds were about 45 mph here, and that was primarily with the OFB. Next line of storms in NC Iowa looks like it's about to approach the same area that just got rocked with the first line, although I doubt they maintain their intensity past the WI/IA/IL border area.

Brewers Posted September 5, 2012 Author Share Posted September 5, 2012 That cell SW of Prairie Du Chien has to be producing some pretty hefty hail. Link to comment Share on other sites More sharing options...

Nice soaking light rain to compliment this mornings 1"+ deluge should probably end the watering season unless we go on a long stretch of dry weather to go with the fall torch.

I agree, but it was not a weenie estimate, unless you think the UW-Milwaukee report was a student weenie estimate, which it might have been. However, it was good enough to be an official report, and that is why I mentioned 45 mph. You didn't even get the more intense part of the storm up here, so I wouldn't expect you to have much more than 30-35 mph winds. Link to comment Share on other sites More sharing options...
BowMeHunter Posted September 5, 2012 Share Posted September 5, 2012 why would my gust front winds be less than yours. your best storm winds were higher with the rain than the gust front then? .08" of rain for the hr at the airport.. must be so windy the rain is having a hard time being measured lulz.

cyclone77 Posted September 5, 2012 Share Posted September 5, 2012 Apparently a large tree took out a corner of a house a few streets over according to a neighbor. Must have been a weak tree, or one that was already damaged in a previous storm. Weird how that happens sometimes. Those elevated sups in northeast Iowa are monsters. They've been impressive for the last hour or two up that way. Going to be interesting to see how that complex moving through northern Iowa interacts with those and the strung out outflow boundary near I-80 later in the night.

Admittedly like I said I'm going off of the estimated winds at UWM. I know they were at least 30-35 mph with the gust front, perhaps more. The actual storm winds were probably similar. The main story here is the rain anyway, and the potential for another round or two to add to the rain in the next 24 hours. Link to comment Share on other sites More sharing options...
cyclone77 Posted September 5, 2012 Share Posted September 5, 2012 Kinda nice seeing these nocturnal complexes raging late into the evening and overnight. The radar looks very much like July or August as we approach midnight. That linear MCS over northern Iowa looks like it wants to kick some serious azz tonight.

Geos Posted September 5, 2012 Share Posted September 5, 2012 Getting some pretty good backwash rains right now with some thunder to boot. Cyclone - those Iowa storms being fueled by the LLJ tonight?

cyclone77 Posted September 5, 2012 Share Posted September 5, 2012 Getting some pretty good backwash rains right now with some thunder to boot. Cyclone - those Iowa storms being fueled by the LLJ tonight? Actually looks like the LLJ holds over the western half of Iowa tonight. This could promote backbuilding storms west of I-35 much of the night. That could have an impact on how things evolve tomorrow. Latest scans looking a little less impressive on the northern Iowa storms. Outflow starting to outpace the main line. Confidence in severe downstream is beginning to decline.

cyclone77 Posted September 5, 2012 Share Posted September 5, 2012 There's gonna be some crazy rainfall amounts reported from those storms over northeast Iowa. Doing a 6hr loop shows that areas around Postville Iowa have been repeatedly hit by strong to severe thunderstorms. Hope there's a spotter or two in some of these areas.

A-L-E-K Posted September 5, 2012 Share Posted September 5, 2012 Looks like at least three outflow boundaries off that complex...timing is pretty poor and it should effectively hold down instability later today (as well as record tying 90 potential) Link to comment Share on other sites More sharing options...
turtlehurricane Posted September 5, 2012 Share Posted September 5, 2012 Debris central Yup, woke up a little while ago to some pretty good wind and rain.

KokomoWX Posted September 5, 2012 Share Posted September 5, 2012 URGENT - IMMEDIATE BROADCAST REQUESTED SEVERE THUNDERSTORM WATCH NUMBER 619 NWS STORM PREDICTION CENTER NORMAN OK 940 AM CDT WED SEP 5 2012 The NWS storm prediction center has issued a severe thunderstorm watch for portions of central and eastern illinois central and southern indiana northern kentucky effective this wednesday morning and afternoon from 940 AM until 500 PM CDT. hail to 1.5 inches in diameter, thunderstorm wind gusts to 70 mph, and dangerous lightning are possible in these areas. the severe thunderstorm watch area is approximately along and 90 statute miles east and west of a line from 45 miles north of indianapolis indiana to 40 miles west southwest of evansville indiana. for a complete depiction of the watch see the associated watch outline update (wous64 kwns wou9). remember, a severe thunderstorm watch means conditions are favorable for severe thunderstorms in and close to the watch area. persons in these areas should be on the lookout for threatening weather conditions and listen for later statements and possible warnings. severe thunderstorms can and occasionally do produce tornadoes. discussion, broken sqln in S cntrl il expected to continue generally E or ESE across the remainder of il and into parts of ind/ky later today. activity is, in part, likely supported by an impulse in the srn stream jet /extending roughly w-e through cntrl parts of ks-mo/. the sqln may be enhanced later this morning by strong sfc heating and light ssely low-lvl flow to its east. while area wind profiles appear somewhat disorganized attm, wind field expected to become more favorable for forward-propagation by midday. coupled with relatively steep mid lvl lapse rates and ample low-lvl moisture, setup may yield both dmgg wind and svr hail. aviation, a few severe thunderstorms with hail surface and aloft to 1.5 inches. extreme turbulence and surface wind gusts to 60 knots. a few cumulonimbi with maximum tops to 500. mean storm motion vector 28030. ...corfidi Link to comment Share on other sites More sharing options...
