SCATTERED SEVERE THUNDERSTORMS ARE EXPECTED ACROSS THE SURROUNDING MIDWEST INTO THE CENTRAL AND SOUTHERN HIGH PLAINS OF THE TEXAS PANHANDLE. ..EASTERN IA/NORTHERN IL/SOUTHERN WI CLUSTERS OF CONVECTION THAT ORIGINATED OVER THE MID MO VALLEY HAVE RECENTLY EVOLVED INTO A MATURE SQUALL LINE OVER EASTERN IA. WHILE MULTIPLE STORM MODES WERE NOTED EARLIER IN THE CONVECTIVE EVOLUTION...IT APPEARS A WELL-ORGANIZED DAMAGING MCS WILL RACE ACROSS ERN IA INTO NRN IL/SRN WI OVER THE NEXT 4-5 HOURS. LEADING EDGE OF THIS ACTIVITY IS SURGING EAST AT 50KT+ AND NUMEROUS MEASURED WIND GUSTS OF 50-64KT HAVE BEEN REPORTED IN THE LAST HOUR OR SO ACROSS IA. IF SQUALL LINE CONTINUES TO ACCELERATE WIND SPEEDS COULD EASILY EXCEED 65KT AT THE APEX OF THIS EVOLVING BOW AS IT SPREADS INTO NRN IL. GIVEN THE CURRENT SPEED/MOVEMENT IT SHOULD SPREAD INTO WESTERN PORTIONS OF METRO CHICAGO BETWEEN 5-6 PM. DAMAGING WINDS ARE HIGHLY LIKELY WITH THIS CONVECTION.

bdgwx Posted June 30, 2014 Share Posted June 30, 2014 Too late now to be posting model outputs for forecast purposes, but the 00Z 4km NAM nest from last night seems to be predicting the MCV track pretty well on it's UH product. In looking at current radar trends the cyclonic bookend vortex that is now showing up appears to be going north of Davenport near the IA/IL/WI border area like what was being simulated 24 hours in advance. So not a bad job if that UH track really does represent the MCV. Link to comment Share on other sites More sharing options...
hawkeye_wx Posted June 30, 2014 Share Posted June 30, 2014 At my house on the west side I actually didn't get it as bad as I expected. The wind probably hit 60 mph, but not 70-80. I think the south side may have gotten stronger wind. Link to comment Share on other sites More sharing options...

Hoosier Posted June 30, 2014 Share Posted June 30, 2014 No surprise considering who issued it. I'm pretty clueless about the inner workings of SPC but wouldn't there be pretty extensive in-house discussion/coordination for something like that? Seems hard to believe that one person would be calling the shots. Link to comment Share on other sites More sharing options...

cyclone77 Posted June 30, 2014 Share Posted June 30, 2014 Radar would indicate the north side of Cedar Rapids had a few mins of hurricane force gusts. Very strong velocity signature passed over that area south of the mesovorticy. Link to comment Share on other sites More sharing options...
hawkeye_wx Posted June 30, 2014 Share Posted June 30, 2014 classic hawkeye mini relative screw zone These lines can be hit and miss with the strongest winds. Two weeks ago most of the city fared ok, but my little area of town was hit hard with trees down all over. This time I was watching out the window, waiting for the trees to really get whipped hard by 70+ mph wind, but it never happened. I'll just have to watch for reports from around the city.
