michsnowfreak Posted February 21, 2011 Share Posted February 21, 2011 Storm total imby: P: 1.13" S: 10.2" DTW officially saw 10.1" complete with thundersnow and 0.06 mile visibility. This actually does squeeze in the list tying for 25th biggest snowstorm officially on record since 1880. What a wonderful storm. It is gorgeous outside. Yes we had some sleet mix cutting down totals SLIGHTLY, but what a treat that the cold air aloft won the battle. So much for an inch of snow followed by ice lol. My mom said to me, imagine if all the old deep snow hadnt melted. This seals the deal for me...an A+ winter. Cars getting stuck left and right, saw two this morning digging themselves out at street corners/gas station. This is easily the best good bust Ive ever seen, replacing Feb 5, 2011. Well over 2 feet of snow on the month now, and this is TWO 10" snowstorms in 3 weeks. EDIT: right after I posted this, I get a text from my sister, and she said "WOW imagine if the old snow hadnt melted wed have soooo much on the ground".

WisTodd Posted February 21, 2011 Share Posted February 21, 2011 I'm calling our storm total 11.0", which is an educated estimate. My location is basically between Andy and West Bend, WI, or about 3 miles NW of Random Lake. I know we had 7.5" by 7pm, and I know 2.2" fell between 10pm and when the snow ended about 12:30-1am. I'm confident that from 7-10pm, we had at least 1.3" (probably a bit more) so I'm comfortable saying we had 11.0". So when's wave 2 going to get here?? (Todd taps his foot impatiently) Oh yeah, then wave 3 for Thursday night! And that program for next Monday/Tuesday looks *very* robust. LMAO.

ILSNOW Posted February 21, 2011 Share Posted February 21, 2011 Skilling Blog Snow's on the way in Chicago and it's likely to push Feb's snow total here to an all time record. Only 1.8" is needed for that to happen. This is our RPM model's take on snow here, which is to commence this afternoon, reach its peak late tonight and taper off during Tues morning. An average of 3.9" of system snow is predicted Chi & north--much less south. Lake enhancement of snowfall is likely to be modest but could add another 1-2"--especially northern lakeside suburbs. Amounts will taper off to the west. Link to comment Share on other sites More sharing options...

ILSNOW Posted February 21, 2011 Share Posted February 21, 2011 have you ever once been optimistic? lol always finding the negatives. I dont see 3.9" here but 1-3" seems like a good bet. Could not have said it any better and this from Skilling Blog This is the Univ of IL's WRF model forecast of water equivalent precipitation with late today & tonight's system. You can see how lakeside counties of northern Il & southeast WI are favored. A good chunk of the precip south will fall as rain before the switchover cutting into snow accumulations there. Cloud temps affect snowflake formation and therefore how much snow you get of a weather system. Those temps imply a snow/water ratio with this system of 11.7 inches of snow for every 1" of water. With an average of 0.32" of water equiv precip predicted with this system, this suggests something like 3.8-3.9" of snow is a good average from the north end of Chicago north. Lighter amounts are likely west & south. Link to comment Share on other sites More sharing options...

Looks like it will miss south based on radar extrapolation..plus latest NAM moves it south of us. Most other outlets going with trace- two inches. Most, if not all of our snow will come with what develops with the upper low later this afternoon/tonight...not what's on radar to our SE right now.

Not even a bit of snow, sleet, or ZR...it was all rain. Hopefully we'll pick up a few inches of snow with the 2nd disturbance tonight. Link to comment Share on other sites More sharing options...

I am being an optimist. I am not looking for or hoping for a 4-5 inch snow. You and I have been down this before. I am more then within the rules of a weather forum to debate the probability of what I feel is an overzealous snowfall call by our local NWS office. Which it appears they are rethinking at this time.With that said, Chi Storms comment that much of our precip. will be driven by the upper low makes me pause and rethink my ideas and also educates me on this system.

SOME FREEZING DRIZZLE MAY STILL OCCUR INTO THE AFTERNOON...BUT IT WILL HAVE LITTLE OR NO IMPACT. AN UPPER LEVEL DISTURBANCE OVER EXTREME SOUTHWEST MINNESOTA WILL STRENGTHEN AS IT MOVES ACROSS SOUTHERN WISCONSIN TONIGHT. THIS WILL CAUSE SNOW TO DEVELOP THIS AFTERNOON AND LAST FOR MUCH OF THE NIGHT. IN ADDITION...EASTERLY ONSHORE FLOW FROM LAKE MICHIGAN WILL CONTRIBUTE TO LAKE ENHANCED SNOW IN FAR EASTERN WISCONSIN.
