What my weather station recorded will have to wait until the power comes back on (the console was giving mom a hard time, and she doesn't want to kill the batteries before the data can be downloaded)

Just got off the phone with my parents, relayed the storm report, and they are getting ready to drive up the road and make sure everyone is alright. That is very close to the house, probably almost right at the end of the road they live on.
Image as the tornado warned cell moved through. The winds were about +48 knots (red) -48 knots (green) in those dark reds and greens, but no well defined couplet was ever really present. That pinkish spot is roughly where the damage report came from, and those winds were about +35 knots.

OTHER WATCH INFORMATION...CONTINUE...WW 113...
DISCUSSION...THUNDERSTORMS WILL INCREASE IN NUMBER AND INTENSITY
ACROSS THE WATCH AREA THRU THE AFTERNOON AS A STRONGLY UNSTABLE AIR
MASS NOW UNCAPPED REF 17Z CHS SOUNDING. PRIMARY THREAT WILL BE
LARGE HAIL AND DAMAGING WINDS AS STORMS DEVELOP UPSCALE INTO LINE
SEGMENTS. ADDITIONALLY SUPERCELLS ARE POSSIBLE GIVEN THE FAVORABLE
DEEP LAYER SHEAR ENHANCING BOTH THE LARGE HAIL THREAT ALONG WITH
ISOLATED TORNADOES.
AVIATION...A FEW SEVERE THUNDERSTORMS WITH HAIL SURFACE AND ALOFT

Re: Severe Weather April 9/10 Upper Midwest
Gino has an ominus AFD from LOT (Chicago) this afternoon regarding tomorrow:
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
237 PM CDT SAT APR 9 2011
...OUTBREAK OF SEVERE THUNDERSTORMS AND TORNADOES POSSIBLE SUNDAY
AFTERNOON/EVENING...
.DISCUSSION...
236 PM CDT
SHORT TERM (TONIGHT THROUGH SUNDAY NIGHT)...
ATMOSPHERE IS THE THE PROCESS OF PREPPING FOR WHAT IS LOOKING TO BE
A POTENTIALLY MAJOR SEVERE WEATHER/TORNADO OUTBREAK LATE SUNDAY
AFTERNOON INTO SUNDAY EVENING.
UNUSUALLY STRONG COLD CORE DEEP LOW CONTINUES TO DIG SOUTHEASTWARD
OFF THE SOUTHERN CALIFORNIA COAST THIS AFTERNOON HEIGHT FALLS IN
ADVANCE OF THIS BIG TROUGH HAVE ALREADY RESULTED IN CYCLOGENESIS TO
THE LEE OF THE COLORADO ROCKIES WITH A WAVY WARM FRONT EXTENDING
EAST FROM THIS LOW ACROSS THE PLAINS TO CENTRAL IL/SOUTHERN IN. WARM
FRONT LIKELY TO SURGE NORTH ACROSS THE CWA TONIGHT WITH UNSEASONABLY
WARM/MOIST AIRMASS SURGING INTO THE AREA. WOULD ACTUALLY ANTICIPATE
RISING TEMPERATURES TONIGHT...ESPECIALLY CLOSER TO LAKE MICHIGAN
WHERE MARINE LAYER IS KEEPING THINGS CHILLIER THIS AFTERNOON.
NOT OVERLY EXCITED ABOUT CONVECTIVE CHANCES TONIGHT...HOWEVER STILL
PLAUSIBLE THAT CONVECTION DEVELOPING ALONG THE DRY LINE OVER THE
EASTERN PLAINS LATER THIS AFTERNOON COULD CONGEAL INTO A CLUSTER
AND SCRAPE OUR NORTHERN CWA. BETTER PROBABILITIES CERTAINLY LOOK TO
BE OVER WISCONSIN...BUT CLOSE ENOUGH CALL TO MAINTAIN A CHANCE POPS.
ANY THUNDERSTORM THAT DOES MEANDER INTO NORTHERN ILLINOIS WOULD HAVE
THE POTENTIAL TO PRODUCE DAMAGING WINDS/LARGE HAIL GIVEN THE STEEP
LAPSE RATES AND STRONG SHEAR.
BY ALL INDICATIONS NOW...SUNDAY LOOKS TO BE WINDY...UNSEASONABLY
WARM AND HUMID. CHANCES FOR ANY LINGERING ELEVATED CONVECTION (WHILE
NOT ZERO) LOOK LOW AND EVEN CLOUD COVER MAY BE AT A PREMIUM AND
MODELS SUGGEST CIRRUS WITH SUBTROPICAL JET WILL REMAIN SOUTH OF US
AND LITTLE IN THE WAY OF CUMULUS INITIALLY GIVEN THE STRONG CAP
RESULTING FROM THE STRONG EML.
MODELS HAVE COME INTO REMARKABLY GOOD AGREEMENT AS TO THE EVOLUTION
OF CONVECTION TOMORROW AFTERNOON AND EVENING. NEARLY EVERY MODEL
(CONVECTIVE ALLOWING AND CONVECTIVE PARAMETRIZED) SUGGEST
CONVECTIVE INITIATION DURING THE MID-LATE AFTERNOON NEAR OR JUST
WEST OF THE MISSISSIPPI RIVER ALONG WHAT APPEARS TO BE A PRE-FRONTAL
CONVERGENCE ZONE. STRONG HEIGHT FALLS AND LARGE SCALE ASCENT
OVERSPREADING THE WARM SECTOR DURING THE AFTERNOON IS FORECAST TO
ALLOW CAP TO WEAKEN SUFFICIENTLY FOR EXPLOSIVE SEVERE THUNDERSTORM
DEVELOPMENT ALONG THIS CONVERGENCE ZONE.
GIVEN THE 50-60KT OF 0-6KM BULK SHEAR WOULD ANTICIPATE STORMS TO
QUICKLY GO SUPERCELLULAR WITH ATTENDANT DAMAGING WIND AND VERY LARGE
HAIL THREAT. RELATIVELY HIGH LCL HEIGHTS AND RATHER DEEPLY MIXED
BOUNDARY LAYER WOULD SUGGEST A LESSER TORNADO POTENTIAL INITIALLY
BUT TOWARD SUNSET AS LOW LEVEL JET INCREASES FROM 30KT TO AROUND
60KT DURING THE EARLY EVENING...RESULTING IN LOW LEVEL SHEAR JUST
BECOMING SICK. IN ADDITION...A SLIGHT COOLING OF THE BOUNDARY LAYER
AND LESS MIXING COULD ALSO ALLOW FOR LOWERING LCL HEIGHTS AND
CREATING AN ENVIRONMENT PRIMED FOR STRONG OR EVEN VIOLENT TORNADOES
GIVEN SUPERCELLULAR STORM MODE.
SPEAKING OF STORM MODE...THIS REMAINS PROBABLY ONE OF THE MOST
DIFFICULT THINGS TO FORECAST AND NOT SOMETHING WE ARE PARTICULARLY
SKILLED AT. HAVING SAID THAT...INITIATION ALONG A MORE SUBTLE
SURFACE BOUNDARY (IE PRE-FRONTAL CONVERGENCE VS COLD FRONT) WOULD BE
MORE FAVORABLE FOR DISCRETE SUPERCELL. ALSO...SHEAR VECTOR
ORIENTATION WRT TO INITIATING BOUNDARY WOULD ALSO FAVOR CELLS
BREAKING FREE FROM BOUNDARY AND MOVING QUICKLY EAST.
FINALLY...HIGHER RESOLUTION CONVECTIVE ALLOWING MODELS (WHICH HAVE
SHOWN SKILL IN FORECASTING STORM MODE) ARE MOSTLY FORECASTING
DISCRETE CELLS. SREF MEDIAN SIG TOR PARAMETER OVER NORTHERN IL
CLIMBS TO OVER 6 TOMORROW EVENING...SO IF FORECASTS FOR DISCRETE
CELLS VERIFY IT COULD GET UGLY TOMORROW EVENING.
AFTER 6 PARAGRAPHS OF SAYING THE SKY IS FALLING...ITS WORTH NOTING
THAT IT IS EXTRAORDINARILY RARE TO GET EVERYTHING TO FALL INTO PLACE
FOR A TORNADO OUTBREAK. IT WOULD ONLY TAKE ONE PARAMETER TO FALL
SLIGHTLY OUT OF WHACK TO RESULT IN A GREATLY REDUCED SEVERE AND/OR
TORNADO THREAT...OR FOR STORM MODE ISSUES TO OCCUR. WHILE HAVING
INITIATION ALONG A PRE-FRONT CONVERGENCE ZONE CERTAINLY DOESNT FAVOR
RAPID EVOLUTION INTO SQUALL LINE...IF CAP WEAKENS TOO RAPIDLY
WOULDNT BE TOO HARD TO ENVISION SCENARIO WHERE SO MUCH CONVECTION
DEVELOPS THAT SUPERCELLS BEGIN TO INTERFERE WITH EACH OTHER. BOTTOM
LINE IS THAT WE ARE STILL MORE THAN 24 HOURS FROM THE EVENT AND A
LOT COULD CHANGE IN THE FORECAST TO RESULT IN A LESS GLOOM AND DOOM
SOLUTION...SO STAY TUNES.

Well, the one cell that prompted the tornado warning in Monona County, IA was interesting to watch on GR...the rotation started about 10 or 15 minutes before the warning was issued at roughly 15000 feet, then quickly built downward in the next couple frames. The rotation then weakened when a cell built up some to the east (about 2 miles to the east), robbing the inflow a little, and it is currently strengthening again.

Re: Severe Weather April 9/10 Upper Midwest
I have a question...that tornado warned storm in Monona County...I noticed the storm had another blob southeast of the rotation on radar, and the blob was flaring up and down, pretty much in tandem with the circulation. Is the blob inflow into the storm that the radar is picking up? I noticed it flared up a couple times right before the circulation strengthened...so I think there is a connection there.
