THE ELEPHANT IN THE ROOM....
The latest EURO is in and it shows little change from its previous run. We have the northern camp of the GFS and the southern camp of the EURO. Here's the comparison. The EURO. A tighter perspective. Now the GFS for the same period. As you can see, there's a significant difference with the EURO much further SE. I see no reason to pick one over the other aside from the fact the the EURO has better physics and a better overall track record than the GFS. It's won far more of the

HOT OFF THE PRESS, NEW SNOW FORECASTS....
The 0z runs of the U.S. models are in the house. The most bullish and eye opening of the 3 was the GFS. It cuts right through the heart of my area dumping up to 12" of snow. You would think with only 36 hours to showtime that would be reliable. However, I'm still reluctant to buy its solution. The one thing I can say in its favor is the fact the last 3 runs have been consistent. That's the first thing you look for in a snow forecast. Another is consistency with other models,

NEW SNOWFALL NUMBERS....
The 18z runs of the U.S. based models have cleared. There was a decided shift north on all 3 versions. The only outlier to these solutions is the EURO which is further southeast.

The GFS The NAM The 3k NAM I'll be surprised if the EURO does not make some sort of move to the north tonight. Then again, stranger things have happened, especially with this storm. Winter storm warnings and a

HEAVY SNOW BAND UP FOR GRABS.....
The morning runs of the models were not especially helpful in regards to refining the snow band with Sunday's storm. Due to that uncertainty there have not been any changes to the winter storm watches previously issued. To be blunt, the heavy snow band is up for grabs! When you see the various forecasts you'll understand why. Lets take a look. The GFS The GFS FV3 The 3k NAM The NAM The EURO A larger Midwest perspective of the EURO. The differences are glaring, especially over

WINTER STORM WATCHES ISSUED....
The storm that's been the focus of my attention all week long is now entering the data rich environment of the western U.S. Models are gaining perspective on the track and where the heaviest snow will occur on Sunday, As a result, the NWS Quad Cities has issued a winter storm watch for heavy snow and high winds. Here it is. These are the specific of the watch. The Des Moines NWS has put southern Iowa under the watch as well. This is the latest snowfall forecast from the hi-re
