February 4-5th Winter Storm


Chicago Storm

Recommended Posts

In looking at GHD 2011, this is the image 3 days out of the projections, rather tight.

 

Interesting to note that the amount of snow that fell in Chicago was pretty darn high the further south the storm dug to pull in the gulf moisture.  Looking at the projected tracks at the time that over a foot of snow was already forecast show its hitting the tip of southern IL into southern OH.

CMC & GEM? Same model.

GHD is getting talked about a lot. But even though there were some suppressed runs thrown in (especially outside 120 hrs), we were seeing pretty consistent signs of a high quality phase and neg tilt tough which we just aren't seeing now.

 

It's the new Jan 1999. :lol:

Yup. I see similarities early on along the WC but after that, compare for yourself...

the afternoon Grand Rapids AFD explained things nicely and blunt. basically if this system remains unphased the southern solutions will prevail and the more phasing we see between the polar and subtropical jet, the more north this thing will pull. so phasing really is one of the biggest factors to watch. 18z run of gfs was hinting at this. now just have to watch for trends

Also with Feb 2011 the energy dug more westward, allowing for a pretty powerful hook. I recall the PNW receiving quite the arctic outbreak and snowfall. This time around it's a bit weak in terms of how the energy digs. The momentum isn't as impressive

Yeah there is a particular TV met in the QC that has really gone off the deep end in that regard this winter.  Even posting it with a disclaimer is pretty unprofessional IMO. 

 

I know who you speak of.  He's an experienced forecaster but he posts those maps via his personal page from Facebook.  He will always show maps out 10-14 days with snow totals and then giving those disclaimers saying it isn't a forecast.  He really should understand people with no weather savvy don't understand that.  And IMO its just unprofessional at the end of the day.  Storms in fantasy land go all over the place generally until we're about two or three days out if you're lucky.  Models this Winter have had a difficult time even with systems within 24hrs.  He'll learn I'd think at some point.  He's taken a beating from some people already. 

 

Regarding the system next week...I just don't wanna see that phasing happen to darn soon and have this thing cut to far W.  That'd be disappointing but I think the safe bet is still a more Southerly solution, especially with an intense Arctic high trying to poke back in but it'll be a battle royal with ridging getting going over the SE...where will that path of least resistance set up for anything to go?  Its the golden question on this pup.

I wasn't around here for GHD, but how did the early January storm compare for you folks who got hit hard by both GHD and January 4-5,2014 in terms of enjoyment?

being roughly 50 miles north of detroit, the January 4-5 storm far exceeded GHD imo. more snow and more wind and cold with the January storm.

it really Is that simple.   GFS shows it perfectly, what happens if the southern stream gets out in front and a  northern piece is able to drop in and phase.  Big height rises in front and hard left turn.    

 

If northern stream stays more progressive and out in front, it'll suppress heights and we have the euro solution.

 

Either solution is on the table and no idea which one is more likely to happen.   We really haven't had a subtropical jet to play with this winter yet so it's hard to tell.

This is about as surefire this far out as it gets with St. Louis.

 

Thanks to the PV.  Something will have to change a lot to pull this thing North through Southern Mo.

 

If the storm is stronger and ejects that far South like SE Texas.

 

Then when you factor the confluence over the lakes.  It will be really tough for this to end up far enough West coming out of E/SE Texas where we don't get snow and sleet before ending as snow.

 

West for a Southern IN/OH person is definitely more of a concern in these setups.  When we talk about needing a NW trend.  My area needs to be in a good spot at the point where the SLP leaves Texas. 

 

If this was going to come out of Oklahoma it could be quickly going from snow to mix or rain.

 

Coming out of Eastern Texas it will be tough for a non closed off bowling ball to go to far NW of STL period.  Let alone wirh that PV causing massive confluence. and speeding things along.

 

One reason we never get 20-25" snows the cyclones are typically moving to fast.  If they are slow they are almost always to far NW.

We have 2 seperate Michigan facebook crews posting this stuff WAY out in advance. I have one friended, the other one I don't, BUT it got linked TWICE in 2 days from friends who aren't weather enthusiasts.

A little OT but I've noticed IWX hasn't even mentioned this storm in their long term discos even though the last three discussions were within their seven day range. I find that odd that nothing has been said about the possibility of a storm impacting their CWA.

That graphic looks like it's from one of the Cleveland TV stations. That graphic must have been made just before a drastic northwest shift.

I don't think there was too much disappointment in Ohio from that as there was probably a good 4 day lead time here of showing nothing. In fact, I can't even recall the GHD storm, so I'm assuming it was a non event here.

Noticed that as well in their AFD's.  I think they want to play it cautious and not hype until they have a valid scientific reason to do so, unlike other forecasters who can be more sensationalist with respect to model swings and excessive qpf.
