Matt Piechota sent us these pictures from his storm chase last Friday afternoon and evening. He describes the pics in further detail below. Thanks Matt!
The pictures above are of an HP supercell in northeast Iowa.
The pictures above show merging supercells in southern Wisconsin, just northwest of the town of Monroe in Lafayette County.
Taken in southwest Wisconsin, this picture was very neat to Matt as there was “a bright light blueish tint above the shelf cloud.”

Showers and thunderstorms will continue early this morning across north central and northeast Illinois mainly in the corridor between I-88 and I-80 then gradually sink south and dissipate.
The gusty winds across the northern suburbs are also diminishing as the showers in that areas weaken.
This will be the last entry on the WGN Severe Weather Blog for this episode unless severe weather redevelops.
Winds from decaying thunderstorms that gusted as high as 55 m.p.h. in Lake County at Waukegan downed some limbs in the Lindenhurst area around 11:15 p.m. according to law enforcement officials there.
Shortly before midnight gusty winds to about 35 m.p.h. hit portions of northern Cook County. The Chicago Executive Airport in Wheeling reported wind gusts to 32 m.p.h. and similar wind gusts were observed in Arlington Heights. The gusty winds will gradually subside after midnight.
Latest radar trends at 11:40 p.m. show a continued weakening trend in the thunderstorm activity and the threat of further severe weather in terms of large hail and damaging winds appears to be over. However, thunderstorm activity will continue into the early morning hours of Tuesday in areas from southern DeKalb and northern LaSalle counties near Earlville and Sandwich in north central Illinois east through Yorkville and Oswego in Kendall County into Will County from Joliet north into southern DuPage County. These storms will produce gusty winds and locvally heavy rainfall.
Wind gusts to 40 m.p.h. were recorded at Waukegan Harbor and and a gusts ato 55 m.p.h. was logged at the Waukegan Airport at 11:05 p.m.
Gusty winds may also occur across northern Cook County in the next hour or so.
Winds gusted to 54 m.p.h. at Waukegan just before 11 p.m. this evening, a result of outflow from dying thunderstorms that moved southeast out of Wisconsin. The gusty winds should continue for about an hour and could gust as high as 60 m.p.h.
Other thunderstorms are moving through DeKalb County producing heavy rain and gusty winds. These storms are in a weakening phase after producing severe weather in northwest Illinois earlier this evening .
