3/15-3/16 Winter Storm

[hawkeye_wx]

DVN issued a blizzard warning for their entire area.  The snow forecast is 4-8", which seems a bit high, plus wind up to 60 mph.

There it is. The entire MPX CWA is under a blizzard warning. That might be a first.

I can see localized 18" amounts for the Twin Cities. Meanwhile Green Bay may have their biggest snowstorm on record.

If the current majority of models are to be believed, not a chance.

We'll see how much sleet mixes in I guess.

The last AFD from Milwaukee-Sullivan is from midnight Friday?  I can’t get anything newer.

Nice! Welcome! I’m a little nervous about the dry slot or mixing making its way into the southern half of the metro, but you’ve gotta be close to maximize the pivot. I think Anoka or Forest Lake is the place to be, but this should be fun regardless.

I think I might actually end up in or close to the bullseye for the metro here in Blaine. Models keep bouncing back and forth a few miles and that’s enough to make a difference in the heaviest band.

This is perhaps a once-in-a-generation amount of blizzard warnings for March, in terms of area (not in Rockies)

I’d definitely feel better in your location versus mine. (Lake Nokomis - S. MPLS) Either way I’ve got cautious optimism in a metro wide 12-18” 

 

Starting to spit flakes here.

18z hrrr is one of the craziest things I’ve ever seen for us. Several hours of 2”+ rates, even pushing 3” for a while. The one thing that could really hamper our totals are the ratios. I wouldn’t be surprised if some of the ratios are under 10:1, maybe getting a bit better as the rates ease up but at that point the winds will ramp up and compact things too.

[mnchaserguy]

Hrrr has the bullseye over the heart of MSP.

[DocATL]

Dumb question but why are the 12km and 3km NAM runs so different? Effectively different models in terms of how they process data?

Looks like MKE didn’t do a morning discussion.

Just saw it. Wow, going to be hard to sleep tonight if that’s what’s in store. Optimism growing. Top 10 or bust!

They're still acclimating to daylight savings changeover.

MPX mentioned low ratios, in setups like these it’s what typically happens. Also it’s mid March not January.

The interesting thing is some of the cams were spitting out big numbers but it wasn’t using crazy high ratios to do it. Some of them had ratios of 11 or 12:1 which isn’t that high, and it was still giving us over 20” totals. Just imagine if we actually got 15:1 ratios for this entire storm lol

I wish there was more posts like the NE threads. This is a huge storm and its like crickets in here and if this was the NE thread it would be page 10000 by now. Just sucks living in the Midwest with the lack of enthusiasm as there is a lack of expert opinions and discussions to learn from by underlinks like me 

If this storm was aligned in the Chicago to Detroit corridor it would be a massive thread.

This is the equivalent of a new England threat where the northern half of Maine is the southern extent of the goods.

Interesting I didn’t dive into that. I usually just look at the 10:1 maps. If we can get extended time in the deformation band, ratios should improve.

Chicago

There continues to be some
differences amongst guidance in terms as to how much additional
moisture will fall as snow in the deformation band of the cyclone
into Monday morning. However, given the expected track of the
system, forecast thinking continues to favor the heaviest snow
axis from northwestern IL into WI, with much lighter amounts with
east-southeastward extent across our area. This results in general
forecast snow amounts in the 2 to 5 inch range in my far
northwest (near the Rockford area), dropping to only an inch or
two across the Chicago area and points southeast.

conditions should become more hazardous with time Sunday night,
with the potential for periods of near blizzard conditions at
times, particularly across the more open areas of
northern/northwestern IL. These poor conditions are expected to
continue into Monday morning before the snow gradually tapers off
from south to north through the day on Monday.

After Dec.8th been living on the margins all winter

[OrdIowPitMsp]

Nice explanation by MPX on pulling the trigger for a blizzard warning. 
 

So the Blizzard Warning... There is high confidence given the snow
totals and strength of winds that blizzard conditions will be
observed in our traditional "blizzard alley" from west central to
south central MN, especially late Sunday morning into Sunday night.
For eastern Minnesota into western WI, blizzard purists may argue
that we don`t hit blizzard conditions of a 1/2 mile or less
visibility with wind gusts of 35 mph or more for 3 or more
consecutive hours. This is because the strongest winds will be
lagging the heaviest snow and eastern MN and western WI really need
the heavy falling snow to achieve the visibility requirements of a
Blizzard Warning. However, we are looking at historic snowfall
amounts for a March storm (see climate section), with travel
expected to be crippled across our entire area tonight into Sunday
night. In addition, when the common citizen looks out the window
Sunday morning (ie. not the blizzard purist!), they`ll likely say,
yup, this is one heck of a blizzard. Given the expected high to
extreme impacts, we felt comfortable in pulling the biggest winter
messaging lever we have, the Blizzard Warning. Simply put, travel is
expected to be very dangerous on Sunday and the best way to get the
message across on just how severe this winter storm will be is to go
with Blizzard Warning.

Yeah…outside of the lake effect areas, people don’t realize how bad of a winter this has been. Rockford has only had 6.9” of snow since 12/8, with a max 2” of snow cover…and bare ground during the entire month of February.

I know many of us had two decent storms prior to 12/8, but all of that snow melted by 12/15 or even sooner. 

I don’t care what the total snowfall is compared to climo. It’s a horrible way to gauge the quality of a winter. It has been a horrible winter in northern IL and southern WI. I wish people would just acknowledge that. It’s ok for people to have high standards.

Having a white Christmas would have helped, and I thought it was a lock after having 10” on the ground on 12/5. And a big dog with the current storm would have helped too, although it would melt quickly due to the time of year. But both of these failed by a wide margin. No white Christmas knocks the grade down by two letters all by itself. 

I know people grade winters differently. I like to communicate things by considering the extreme outcomes of a situation, because it adds context.

This is what I mean - some people might argue that our area has 6 months of winter, since it can snow during November-April. That’s technically true, but to me that’s dumb. Just because it can snow during April, it doesn’t mean it’s a wintry month. That approach is a 1 on the “degree of difficulty/level of standards” scale for grading a winter, if you use a 1-10 scale.

On the other extreme, someone else could argue that we don’t have any winter in this area at all, because there is no calendar date on which you can guarantee that it will look and feel like winter outside (meaning cold temps with meaningful snow cover). While late January has the best probability of this occurring, there are some years with warm temps and bare ground at that time of year. That approach would get a 10 on the aforementioned scale. Even I wouldn’t go that extreme, but my approach is probably an 8. This is because, in many (but not all) winters, you can count on 20-40 days (not necessarily consecutive) when it’s cold with meaningful snow cover (say 3”+ so there are no annoying bare spots).

I’m only pointing this out because, especially on a weather forum like this, it would be more fun and there would be better camaraderie if we all fell in the 7-10 range on this scale. But I think most of this forum falls into the 2-4 range on the scale…which I think is unfortunate. Just like your favorite sports team, I like having high standards for winter, whether or not it’s logical. 

I know this post is OT, but missing out on the current storm was the last straw, plus I’m not able to chase it due to other priorities. 

Anyway, I hope the good folks up north post a lot of pictures.
