raw data for ORD off the Euro. GFS/Euro holding their ground regarding track with the GEM taking a significant jump north from its 0z run. Euro also showing another big system after this one...988mb sfc low in eastern NE at 228hr.

As far as the origin of where it comes from and the track, this storm reminds me of december 19th 2008. That storm didn't occlude I dont believe but it was a spread the wealth strom as it tracked accross the country.

That storm kicked butt.. Great wind driven event and in fact that was the 1st time I ever saw Thundersnow. Was standing on my porch smoking a cig and the sky lit up and heard the crash.

DVN

I'd be happy with either of those lol quite the spread.

SUN THROUGH TUE...HAVE LOW CONFIDENCE IN THE STRENGTH AND TIMING OF

THE UPPER LEVEL SHORTWAVE AND ASSOCIATED SURFACE CYCLONE THAT MAY

AFFECT THE AREA FROM SUN NIGHT THROUGH MON NIGHT. THE 12Z GFS AND

UKMET ARE FASTER AND MORE NORTHERLY WITH THE SURFACE LOW TRACKING

ACROSS NORTHERN IA AND SRN WI SUN NIGHT INTO MON...WHILE THE ECMWF

AND GEM ARE MUCH DEEPER WITH THE UPPER LEVEL SHORTWAVE AND THUS HAVE

A SLOWER AND MORE SOUTHERLY TRACKING SURFACE LOW TRACKING ALONG A

TIGHT BAROCLINIC AXIS THAT WOULD IMPACT THE AREA LATE SUN OR SUN

EVENING THROUGH MON NIGHT. THE GFS HAS SLOWED SOME OVER THE PAST

COUPLE RUNS...WHICH MAY LEND SUPPORT TO THE ECMWF.

FOR NOW...WITH LOW CONFIDENCE IN ANY DETAILS...HAVE RAISED POPS FOR

RAIN OR RAIN SNOW MIX ACROSS THE NORTH FOR THE SUNDAY NIGHT PERIOD

THAT MODEL CONSENSUS WOULD FAVOR. OTHERWISE...HAVE KEPT FORECAST

SIMPLE WITH MAINLY RAIN OR RAIN/SNOW MIX...CHANGING EVENTUALLY TO

SNOW BEFORE PRECIPITATION ENDS MONDAY NIGHT. WILL CONTINUE TO

MONITOR THIS SYSTEM OVER TIME...AS THE MORE NORTHERLY TRACK WOULD

BRING POTENTIAL FOR THUNDERSTORMS AND MODERATE RAIN TO HEAVY RAIN

THAT COULD AFFECT RIVER FLOODING...WHILE A MORE SOUTHERLY SOLUTION

COULD BRING WINTRY MIX OR EVEN MODERATE TO HEAVY SNOWFALL.

Given the fact that this system lacks significant cold air availability I'm thinking this thing brings mainly rain here. Minnesota through Michigan look in the game though. Even the southerly Euro holds mid level temps way up here. If we're going to be on the warm side of the storm I hope it gets warm enough for some decent thunderstorms.

12z Euro would imply a significant ice threat not that far north of here.

It would be close.. Very close.

As I indicated earlier that is what I am concerned about for Michiana and the I-80 corridor east from Chicago. Plus climatologically this is the time for ice storms in our region.

Yeah there would be a decent amount of mixing on this run near/just south of the state line but all frozen though. per euro 2m temps areas along and north of the border ( east of Berrien county ) fall to 20 or colder during the height of the storm. The 32 line makes a attempt to make a run north/ne but gets stopped at i94 in NW IN ( hr 156 ) and never makes it farther east/ne of there.

The ECMWF brings 60F+ temps and 55F+ DP's up into C. Illinois, close to PIA.

How could that be? We got just over a foot, so unless the ratios were 20:1, which I doubt they were due to the wind, we had to have received more than .59 QPF.

Not only do the ASOS have problems of this sort, Co-op stations have problems with liquid equivalent in events with such high winds because the gauge fails to catch some of the snow that falls. Therefore, liquid equivalent measurements end up lower than they ought to be.

Chi Storm...Nice Avatar.

The mixing line looks awfully close to the string of cites.. Gona have to wait and see on what if any blocking we can get to the North to push this slut further south.

The only redeemable quality of Respiratory Guy was his avatar of that girl with the ass you could bounce a dime off of. That pic trumps Chicago_Storm's and Cyclone's.
