WINTER STORM UPDATE...

New data has been coming in regarding the impending snow system. As I indicated in last nights post, many models have shown a trend to shift the max snowband further southeast from where it was situated yesterday. This is supported by most models and is the way I am leaning. The odd man out right now is the GFS which so far has held on to its idea of the heavy snow band further northwest. If I had to hang my hat on one model it would be the EURO and you can see what it suggests below. It runs a heavy snow swath northeast right through the heart of my area, including the Quad Cities.

The EURO

The GFS as you can see is much further northwest.

I think it's too moist and I'm expecting it to shift SE at some point to be more in line with other models.

The HRRR

The 3k NAM

The 12k NAM

The Canadian GEM

This is interesting too. It's the NWS official snowfall forecast issued at 7:37 this morning. It's still favoring the NW and I assume the next run of this model will also be further southeast.

Currently the Winter Storm Warnings in place are off to the NW of the Quad Cities.

These may be pushed a county or two southeast to include many of my counties along the Mississippi. Also, heavier snow is also likely deeper into the area southeast of the Quad Cities. Instead of 1-3" totals, amounts for much of that area could reach 2-4", lightest in the far southeast corner of my region. Amounts from Burlington to Sterling Rock Falls NW through the rest of my area should be in the 4-7" range. Bottom line, the majority of my area should see 3-7" of snow, maybe 8 in localized spots with banding. The snow begins late tonight or early Thursday and ends in all areas by early evening.
