Late March snow blitz! March 24-25th

I agree.

With that said points just east may receive slightly higher amounts due to the cover of darkness negating the extreme sun angle this time of year. If thunderstorms get going on the southern end of the system, watch for moisture enhancement riding north as well...

and the laf boys said their snowstorm chances were done a month ago lol

Can't speak for Tim but I remember saying that it transitions into hoping for a fluke. To put in perspective how rare this is, Chad Evans came up with a list of late season snowstorms for LAF since 1821 (the early years are from newspaper/diary accounts). There have only been 4 storms to drop 6+ inches after March 20 (3/23/1836, 3/26/1913, 4/18/1926, 3/25-26/2002).

Late march 2012 was wild at purdue with back to back moderate snowfalls. That was my senior year. It really did nothing that entire winter until then. Very strange.

Wow crazy that they looked back to 1821. Did a quick glance (I have a list of every 6"+ storm since 1910), and since 1910 Detroit has seen 12 storms drop 6"+ after March 20th (I used 1910 even though records started in 1880 because I am missing a little data before that. You can certainly add several to the list from 1881-1909).

Chad has some missing years too so it's possible that the list from above could be understating things a bit but the bottom line is that it's pretty darn uncommon. Climo certainly favors areas farther north but this regime of late is anything but typical.

Last time I remember a significant snow in March (long ago) there was thunder snow. Is there any chance of that with this storm?

There is severe storms forcasted to the south, so if some of that moisture can ride up over the cold air thundersnow is a possibility.

How far north does the snow swath make it in Ohio?

Better than previous runs for CLE:

Who cares about the NAM. You can see the errors it makes by 24hrs. Considering that the system is going to split in half, less potential anyway you go about it. Finding the defo band is probably will the best accums will be. The models won't know where it sets up to Sunday.

 

the nam is a joke even though it would be a solid hit here.   I swear this thing seems more like a double barreled low that splits with the front one racing away.  It's like the coastal transfer never really finishes

Updated ILN Graphic.

 

 

Low pressure will travel through Kentucky into Ohio from Sunday into Monday. Significant snowfall will occur for parts of the region. Warm air will be pulled into the area from the south and bring rain to southern Ohio and most of Kentucky, limiting snow totals here. The low will exit the Ohio Valley early Monday, but cold air will wrap around and stream in on northerly winds. Any precipitation that occurs on Monday will be snow for the entire region and additional lighter accumulations are likely.

LOT appears to have moved the likelihood of significant snowfall farther south.  No change in the snowfall graphic for the entire CWA, but there is a WInter Storm Watch for S. of I-80

Hmm.. perhaps I might see an inch or two....

That's all I am willing to deal with, this late in the season... :guitar:
