Winter 2014/15 Med/Long Range Discussion Part 3


Chicago Storm

Recommended Posts

The 12z GGEM also has a storm around the Feb 14-17th time period. Intriguing time frame as the PNA ridge looks to break down some with a slightly positive NAO. Still 7 days out but lets see. 

 

yea you guys are in a great position.  I'll be very dubious of any solutions showing snow south of I-80 with a continued positive NAO and strongly positive AO.   This has wash, rinse, and repeat written all over it.

which is what the euro came in with.  A w to e bowler that is bullied south thru the TN Valley.

Nice SE Ridge on the model too. Keeps that gradient tight esp with the PV up north. Any thoughts? 

 

GGEM is an overrunner. 

Too early beyond talking in generalities, but this does look like a potential storm for the region about 8-9 days from now. There has been consistency in a storm potential, the details have been fuzzy though and probably will be for a while.

Good point, I agree. Models have been atrocious this year and I wouldn't be surprised to see some wild solutions. Potential is there, we just need the right "ingredients" to come together. Let's see.

Heh, GFS already spitting out 20-24" jackpots, think about if this comes through and pulls a SB storm ramp up near the end.

 

Oh, and would be nice if one of these things had instability to work with on the warm sector side, but I doubt it given the repeated cold intrusions into the Gulf.  :ee:

Yeah what a storm on the GFS.

 

20 degree temperature gradient at 850mb across IL. Pretty nuts. 

985mb low at Cincinnati on the GFS.  I don't believe there will be 985mb there, because that would be a once-in-a-decade type of SLP, given the tendency for higher pressure over the continent in winter. It might be a snowy Feb 17th for Northwest Ohio if the placement of precipitation is close.

Not saying it will happen but if the pattern supports it which this one would, it is possible to have a storm that strong.

While Detroit is in SE Michigan it does not represent SE Michigan in regards to storms. There have been several larger snowstorms in SE Michigan than the one that just occurred last week.

Six events of 12-18" since 1999 north of 59 to i-69. 1999,2000,2005,2008,2014,2015.

Yeah it's not the ones around a foot as both Detroit and Toledo are good for one 10"+ a year. It's the 15"+ or blizzards that get remembered

 

Greatest snowstorms in Toledo's history

1. February 28 - March 1, 1900, 22".

2. December 1-2, 1974, 14"

3. January 5, 2014, 13", "Polar Vortex Blizzard"

4. January 13, 1910, 12"

4. January 26-27, 1978, The Great One, 12" (with 10 ft drifts)

4. January 1-2, 1999, unofficially 12" in north Toledo

4. January 22-23, 2005, 12" (I personally only measured only 9" near the Airport)

4. February 1-2, 2015, 12"

9. November 16, 1932, 11.5"

10. February 21, 1912, 11"
