DVN getting all meteorolical and stuff .... pffffff :nerdsmiley:

AREA FORECAST DISCUSSION

NATIONAL WEATHER SERVICE QUAD CITIES IA IL

332 PM CST THU JAN 19 2012

BASED VERIFICATION OF MODEL FORCING AND VERIFICATION OF THE LIGHT

SNOWFALL/FLURRY EVENT FROM THIS MORNING...CONCERN CONTINUES THAT

MODELS ARE OVERDOING QPF AND CONTINUE TO TREND TOO HIGH WITH

SURFACE DEWPOINTS IN THE ARCTIC AIRMASS THAT IS IN PLACE. LOOKING BACK

AT THE FORCING...THE LIGHT SNOW THIS MORNING APPEARED TO BEST

ALIGN WITH THE NORTHERN EDGE OF THE STRONGER FRONTOGENETICAL

FORCING AND OMEGA FIELDS. BASED ON THIS...AND CLOUD TRENDS SEEN ON

SATELLITE IMAGERY TODAY OVER THE HIGH PLAINS AND CENTRAL PLAINS...HAVE

TRENDED TOWARD THE MORE NORTHERLY MODEL SOLUTIONS SUGGESTING A

NORTHWARD SHIFT IN OUR ANTICIPATED SNOWFALL. THE NAM AND ECMWF ARE

NOW THE MORE NORTHERLY SOLUTIONS AND HAVE FOLLOWED A BLEND OF

WHERE THESE PLACE FORCING AND QPF/SNOWFALL...ADJUSTED DOWNWARD

SOME BASED ON A SLIGHTLY MOIST MODEL BIAS.

Will be interesting to see the AFD's and if they discount/give less credit to the Nam+Euro solutions again..

Nice to see some disco on this... Can't wait to see the 0z runs..

I give it a 90 % chance that the transition zone between precip types that are yet to be determined will set up like below. It happens during every transition zone storm, for this area. Mabe a little less dramatic then below, but it does.

Got to get your short term model fix, eh? :lol:

Good luck with this system. Hopefully there are good things in store for you.

Haha, yup. Thanks man, you too.

yikes...3 inches in my front yard and a dusting in the backyard . . . lol

Hahaha! Good stuff.

I had saved this graphic from earlier for something to look back on and laugh at. Maybe future avatar material lol.

I was curious, so I had to take a look at the RPM. I don't think it looks that bad...like no snow at all for Chicago or cyclone's backyard bad. Seems it's dropping the snows farther south (and developing some farther west towards DSM) at the end of its run (4:30PM)...granted after the initial band does its dirty work farther north and west.

Yeah, LOL. That looks like Cher after a nuclear explosion too. Poor gal needs a make-over 911!!!

Lmao!!

Yeah it does swing the tail through areas that were missed with the WAA wing snows. Very similar to what the Euro has been showing.

Tom Skiling just showed a "updated" RPM model. His model went south with the heaviest axis of snow over Chicago area with the cut off being well south of Kanakee. Take it for what it's worth!

Good. LAF will take this one for the team. Not that we need to hinge our expectations on the RPM of course. :D

I guess I thought by your original post, it was a complete whiff. lol, obviously you were just commenting on the WAA snows. Sorry, I'm just rooting for you all to get a good snow and am looking for any good things/silver linings I can find.

Some of the more W-E orientated solutions are hard to buy into given where the low level baroclinic zone will line up...and even if things trend that way, i have to imagine the snows along the WAA wing could over perform.
