Strong to Severe Storm This EveningJune 30th, 2014 at 3:51 pm by Bill Steffen under Bill's Blog, News, Weather
Severe T-Storm Watch for Berrien and Cass Counties. Still getting some wind damage reports from WI/IL – but they are spotty. SPC SAYS THIS IS A “PARTICULARLY DANGEROUS SITUATION!” Update from SPC: WIDESPREAD DAMAGING WINDS ARE SPREADING ACROSS NORTHERN ILLINOIS AND SOUTHERN WISCONSIN. EXPECT 60-75-MPH WINDS TO REACH CHICAGO TO MILWAUKEE DURING THE 545 PM CDT TO 700 PM CDT TIME FRAME. BRIEF TORNADOES MAY ALSO OCCUR. DISCUSSION…THE ONGOING MATURE…DERECHO-PRODUCING MCS IS EXHIBITING AROUND 50-55 KT OF FORWARD MOTION AND HAS LIKELY REACHED PEAK INTENSITY. WIDESPREAD DAMAGING WINDS HAVE BEEN REPORTED…WITH A RECENT WIND GUST TO 78 MPH MEASURED IN SWRN WI. THE FAST SYSTEM MOTION WILL ENHANCE INFLOW AMIDST AN EXTREMELY UNSTABLE AIR MASS TO SUPPORT MCS MAINTENANCE AND WIDESPREAD DAMAGING WINDS ACROSS NRN IL AND SRN WI INTO EARLY EVENING. LINEAR EXTRAPOLATION OF THE ONGOING ACTIVITY TAKES THE SVR-WIND THREAT ACROSS THE CHICAGO AREA AND MILWAUKEE…PRIMARILY BETWEEN 545 PM CDT AND 700 PM CDT.” Dewpoints have been in the mid-upper 70s across Illinois this afternoon – really adding fuel to the fire. The storms in Wisconsin and Illinois are going to hit here this evening…maybe 8:30 pm at the lakeshore and 9:15 in G.R. and Kalamazoo. Get ready. Take down hanging baskets, keep your garage door closed, esp. if it faces west, secure trampolines, pick up and secure anything that might blow around (garbage bin, toys)…don’t park under a tree.
