Nice writeup by Izzi from "NWS ORD"

RELUCTANT TO EVEN BRING IT UP...PARTIALLY DUE TO DENIAL AND

PARTIALLY DUE TO SO MANY UNCERTAINTIES...BUT THERE DOES APPEAR TO BE

THE POTENTIAL FOR A WINTER STORM TUESDAY INTO TUESDAY NIGHT

SOMEWHERE IN THE MIDWEST. ID BE REMISS TO NOT DISCUSS THE

DIFFICULTIES IN SEEING A WINTER STORM THIS TIME OF YEAR AS HIGHER

SUN ANGLE/INSOLATION MAKE ACCUMS DIFFICULT DURING THE DAYTIME AND

WARM PAVEMENT/SOIL TEMPS ALSO MAKE ACCUMS MORE DIFFICULT. THOUGH NOT

IMPOSSIBLE (SEE CHIPNSLOT)...CLIMO CERTAINLY ARGUES AGAINST A

SIGNIFICANT SNOW THIS LATE IN THE SEASON...HOWEVER ECMWF AND GFS

HAVE BOTH COME INTO LINE WITH A SYNOPTIC SYSTEM THAT WOULD

DEFINITELY POSE A LATE SEASON SNOW STORM THREAT. THE MILLION DOLLAR

QUESTION AT THIS DISTANCE IS WHERE IT WILL TRACK AND JUST HOW STRONG

IT WILL BE AND AT THIS DISTANCE ITD BE IRRESPONSIBLE TO LATCH ONTO A

SINGLE MODEL OR ENSEMBLE SOLUTION. ABOUT THE ONLY THING CAN BE SAID

WITH ANY DEGREE OF CONFIDENCE AT THIS DISTANCE IS THAT A STORM

SYSTEM THAT BARES WATCHING COULD THREATEN THE REGION NEXT WEEK. JUST

FOR GRINS AND GIGGLES COULD MENTION THAT THE ECMWF HAS ANOTHER

POTENTIAL SNOW AFFECTING AREAS NEARBY BY LATE NEXT WEEKEND AS WINTER

2010-2011 SEEMINGLY STRUGGLES TO BECOME THE WINTER OF

2010-2011-2012!

DVN

MONDAY NIGHT THROUGH TUESDAY NIGHT...TRENDS OF ALL SOLUTIONS PAST 24

HOURS AS LAST UPPER DISTURBANCE ROTATES NE INTO OHIO RIVER VALLEY.

LOCAL TOOLS AND TECHNIQUES INDICATE .2 TO POSSIBLY AS MUCH AS .4

INCHES OF LWE TO FALL OVER SE 1/3 TO 1/2 PLUS OF FORECAST AREA. SNOW

TO WATER RATIOS OF 15 TO 1 ARE SUGGESTED FOR AREAS OF 3 TO LOCALLY

NEAR 6 INCHES SUGGESTED WITH NEAR 6 INCH AMOUNTS MOST LIKELY SE OF A

STERLING TO MOLINE TO OTTUMWA AXIS. SINCE THIS IS SPRING AND

DECELERATING JET PATTERN...EXPECT FURTHER CHANGES WITH JET STEAK

LOCATION/S SUPPORTING CONFIRMATION ON AMOUNTS AND COVERAGE TO TAKE

ANOTHER 36 TO PROBABLY 48 HOURS. KEY IS THIS AMOUNT OF SNOW IN SE

SECTION TO HAVE LITTLE OR NO IMPACT ON AREA RIVERS SINCE GROUND NOT

EXCEPTIONALLY WET...MODERATE AT MOST WATER AMOUNTS AND WILL MELT AT

MODERATE RATES WEDNESDAY AND THURSDAY.

70"+ for you, 60"+ for me. Would be a nice way to wind down winter.

But if it doesn't materialize, no bitterness from me. It's been a very good winter with or without any more snow.

Yeah, either way its good. One hand nice snowstorm, on the other hand I don't have to drive home in a nightmare Tuesday Night if it misses.

2 months ago this thread is on part II by now.

I think if/when we get better model agreement on a winter storm then it will ramp up a bit. Euro was an improvement with a nice hit for NE/western IA but weakens it quite a bit as it moves east.

0z runs tonight and 12z runs even more tomorrow should be a big help.
