OHweather Posted February 11, 2012 Share Posted February 11, 2012 I would get in your car drive there... I would not be surprised to see 15 to 20 inch amounts! The band has been slowly shifting around since it started organizing over NW IN 4-5 hours ago...if it can stall someone will see over a foot though if not 18"...it's tough to tell if/when a lake band will park. We get hit with lake effect in NE OH pretty good at least once per winter, but I definitely would like to get into one of these long fetch bands some day soon...either a N-S band off of Michigan/Huron, a W-E band off of Superior/Ontario or a SW-NE band off of Erie.

OHweather Posted February 11, 2012 Share Posted February 11, 2012 Gino Izzi's AFD to go along with the upgrade: .DISCUSSION... 1150 PM CST HAVE UPGRADED PORTER COUNTY TO A BLIZZARD WARNING FOR THE REMAINDER OF THE OVERNIGHT HOURS. AFTER MAKING NUMEROUS CALLS TO LAW ENFORCEMENT AND PUBLIC ACROSS NORTHERN PORTER COUNTY REALIZED THAT CONDITIONS WERE EVEN MORE SEVERE THAN PREVIOUSLY THOUGHT. VISBILITIES HAVE BEEN REPORTED TO BE LESS THAN ONE CAR LENGTH AND ONE PERSON WAS QUOTED AS SAYING THIS STORM MAKES LAST YEARS BLIZZARD SEEM LIKE NOTHING. COMBINATION OF EXCELLATION OF WINDS WITHIN THE CONVERGENCE BAND AND CONVECTIVELY MIXING DOWN WIND GUSTS AM CONFIDENT THAT THE WIND SPEED AND VISIBILITY CRITERIA FOR A BLIZZARD WILL BE MET. REPORTS OF 8-10 INCHES HAVING FALLEN SO FAR WITH SEVERAL MORE HOURS OF INTENSE SNOW WITH RATES OF 2-4 INCHES PER HOUR EXPECTED. STORM TOTALS OF A FOOT AND A HALF STILL LOOK LIKE A DISTINCT POSSIBILITY. IN ADDITION...BURNS HARBOR JUST CAME IN WITH A 52 KT GUST AT 0521Z UNDERNEATH THE INTENSE LES BAND. STILL THINK THERE IS A POSSIBILITY OF ISOLATED THUNDERSTORMS OVERNIGHT WITHIN THE BAND AS WELL GIVEN THE EXTREME LAKE INDUCED INSTABILITY. Link to comment Share on other sites More sharing options...

OHweather Posted February 11, 2012 Share Posted February 11, 2012 son of a b*tch. pretty sure I'll take the blizzard over this 100 times out of a 100. I probably would too (if I lived in Chicago) but being a bit of a lake effect snow nut, I'd be doing back flips right now if I lived in Porter County. Guess it depends on your perspective. This band is obviously a beast. Strong convergence extends down the whole axis of the warm lake, the band has literally created its own mesoscale environment...

BuffaloWeather Posted February 11, 2012 Share Posted February 11, 2012 The bold is why I would take this over any blizzard. Totally agree! Absolutely love seeing bands such as these around the lakes. Buffalo receives several bands such as this during any given winter. The one during 2001 brought us 6 inches+ per hour snowfall rates for several hours. Receiving 82 inches of snow in 4 days. I would take any Lake effect snowstorm over any synoptic blizzard easily. Our biggest snowstorms are from lake effect, no synoptic storm even comes close to snowfall rates that are within lake effect snow. Wonder if anyone in that area will approach 2 feet when all is said and done! Link to comment Share on other sites More sharing options...
cyclone77 Posted February 11, 2012 Share Posted February 11, 2012 And that would be from us. Wow, that would be 12"/hr type rates over that short period. Would love to see some HD video of intense rates like that. Link to comment Share on other sites More sharing options...

OHweather Posted February 11, 2012 Share Posted February 11, 2012 It was a real brief burst...we're hanging between 1/8 and 1/4 mi now...were definitely down to about 100 yards at one point. What was flake size like in the band? With the extreme lake induced instability in the lowest levels which due to the cold 850mb temps coincides with the DGZ, I'd imagine very high ratio dendrites falling but the winds are awfully strong. 1" in 5 mins is insane, either way.

That's a pretty healthy total! Seemed like the band remained somewhat transient last night and didn't stall in one given area too long. I was expecting to see some 18" totals this morning, but that's pretty serious total! Link to comment Share on other sites More sharing options...
