Chicago Storm

.

All of the so called “guru’s” have failed this far. Not saying he’s one per say, but will lump him in given he’s almost always talking cold for somewhere. .

My top 10 events for 2019... 1. June 25th severe t'storm. Produced 2.25" hail and 50-60mph downburst winds imby. 2. April 14th snowstorm. 7.5" of snow imby, and 5.4" at ORD. 3. Halloween snowstorm. 6.5" of snow imby, 4.6" at ORD. 4. April 27th snowstorm. 5.5" of snow imby, and 2.5" at ORD. 5. February 11-12th ice storm. 0.30-0.55" ice accrual across the area, with some tree damage/power outages. 6. Late January cold. High temps in -10's and low temps in -20, with -50 WC's. 7. Christmas record warm temps. 8. Veterans Day snow event. 4.0" of snow imby, and 3.4" at ORD. 9. Post Veterans Day record November cold. 10. April 27-May 3rd heavy rain event. Area totals of 4-9" of rain, with flooding.

61 ORD and 62 MDW today. As mentioned before, previous record for the date of 55 was easily surpassed.

Trees budding and flowers coming up around the area. Welcome to spring. .

60 at ORD as of noon. PWK torching at 62. .

Topped out at 61 MDW and 57 ORD today. Looks like low 60's a lock tomorrow, with the record of 55 likely being blown away.

Never though I'd experience a 6"+ snowstorm on Halloween, followed by 60F and shorts weather on Christmas...in the same year.

60 at MDW. ORD lagging at 56 though. Records broken across the state already at RFD, MLI, PIA, UIN, SPI and more. .

Temps might overachieve today, with less cirrus than expected. Already around 60 as far north as MLI and PNT. .

zzzzz... Edit: Should mention that since my last post last week, the GEFS caved to the EPS in showing fairly close to the same as below.

After that 1-2 run change, they reverted back. .

As you could probably figure out by the current/upcoming pattern, the Euro ENS were correct in handling/depicting a +EPO...while the GFS ENS failed horribly. The bad news...If ENS have a good handle on things, that upcoming potential pattern change guidance was hinting at to end December and begin January might be in jeopardy. The Euro and GFS ENS are showing a continued +EPO continue right on into early January. On top of that, the Euro ENS also have a +AO/+NAO/neutral PNA set in as well. The GFS ENS are a bit more subdue overall, more similar to what we are seeing now. Also of note, is that some of the GFS and Euro ENS have the MJO moving from the COD on into phase 6 for the late Dec/early Jan time-frame. If that were to happen, combined with the potential teleconnections in projected, and the fact the main PV will be up over the North Pole/Siberia...things *could* get even more torchy/snow-less...and that's saying something given how the past 5 weeks have been. Not saying that will happen... But the projected teleconnections alone should be a concern that an overall mild/snow-less pattern continues into at least early January.

Exactly what I was thinking. Definitely a positive step, but I could see how the northern zone will still be an issue at times.

The changes are finally coming...

The "people" have been wrong so far. So I wouldn't put too much stock into what they say. However on the flip side, it does appear there is support for the potential of a more favorable pattern for cold/snow around or after the New Year. The GFS ENS are more gung-ho on this than the Euro ENS though.

Equal chances either way that far out. However, it is sort of interesting at the same time that there is not even a long range fantasy storm heading into January.

A lot of valid questions/possibilities.

You know it’s bad when the GFS doesn’t even have a fantasy snowstorm the entire run...which extends into the first days of January. Not just for our region, but the whole country pretty much. .

0.3" at ORD and 0.2" here last night.

12z GFS was a nice torch for Christmas, and the days prior.

So.....post more then? .

You mean the pre-Christmas warm up. .

It came north, with more of a slight SW-NE swath/track. It can only go so far north though, with the PV lobe swinging into the northern lakes from Canada. .
