MONDAY UPDATE: March 4, 2013, 10:27 a.m.
SUNDAY EVENING UPDATE: March 3, 2013, 5:28 p.m.
Hello friends! The timing of the “Winter Storm Watch” has changed and there is now a “Winter Weather Advisory” north of the Quad Cities late Sunday night through Monday evening. However, the bottom line is that snow will be moving in overnight tonight to the north and west and throughout Monday.
Some accumulation is expected area wide through Monday evening with the heaviest up around Dubuque and Maquoketa, Iowa, and Galena, Illinois. But, the heaviest snow for the rest of us will come Monday night and Tuesday.
I’m still looking for the possibility of 6″+ of snow in the Quad Cities, northward across Illinois, and northwestward into Iowa with lesser amounts southeast of the Quad Cities.
For specific numbers (snotals — snow totals) for this two-day storm, join me tomorrow morning from 5-7 a.m. on CBS4!!!!!!!!!!!!

Happy Sunday everyone! After a chilly morning with lows in the single digits and the teens across the Mississippi and Illinois Valleys, we’ll see plenty of sunshine today with increasing afternoon high clouds and highs around 30-35°.
Light snow will develop across Iowa tonight and should be moving into the Quad Cities by daybreak Monday. I expect light snow Monday and Monday night with moderate snow possible Tuesday.
As of Sunday morning, here are the counties under a “Winter Storm Watch” for Monday and Tuesday.
Let me point out something that has people who live in Knox and Stark counties confused. They look at this and say “wish we were getting snow in Galesburg” or “no snow in Knox County?”
That isn’t the case. You will be seeing snow from this system. The problem lies with the fact that those two counties are under the Lincoln National Weather Service office and not the Quad Cities. So, it’s up to that NWS office to issue a “Winter Storm Watch” and they haven’t.
By the way, here’s an updated map from NOAA on the chances of seeing up to eight inches of snow Monday morning through Wednesday morning.
If you now scroll down to the bottom of this blog, you can see the forecast from last night and how much or how little it has changed.
As it looks now (and yesterday) and there’s no reason to change my forecast, “a good starting point is a widespread 6″ or more of new snow Sunday night through Tuesday!”
I’ll continue to watch this and give you update this evening before I get a few hours of sleep before my big weather debut tomorrow morning!

Beautiful sunshine on this Saturday and the snow is beginning to melt. However, that’s deceiving because the highs near 30° are about 12 degrees below average for early March!
Another mostly sunny day is expected Sunday with highs in the mid-30s.
That’s when the next storm begins to affect the area with increasing clouds Sunday night with some light snow developing across Iowa.
Snow is expected to become widespread early Monday and last into Tuesday. Since this could be another long-lasting snow event, accumulations could easily start adding up! Remember that the snow that started last Tuesday and lasted through Friday dropped, officially, 9.4″ in the Quad Cities in at the airport in Moline, Illinois.
A “Winter Storm Watch” has already been issued for much of the eastern Iowa and northwestern Illinois from Monday morning through Tuesday afternoon. That’s indicated by the blue coloring on this map.
If you have travel plans across the Midwest, you can see by this map that we are not the only ones under the “Winter Storm Watch”. That pink over North Dakota is a “Winter Storm Warning”.
I expect light snow to start late Sunday night and for it to snow all day Monday and Monday night.
Here is NOAA’s GFS forecast map for noon Monday. Notice that one shade of darker green over eastern Iowa. That’s the snow I’m expecting through Monday night. However, look off toward the Dakotas. That’s more snow in the darker greens.
I think the heaviest of the snow will fall Tuesday based on what I’m seeing right now. Here’s the NAM forecast for 6 a.m. Tuesday. Those darker greens indicate moderate to heavy snows.
And, here is the 6 a.m. GFS model showing pretty much the same thing with heavier snow Tuesday.
While the beginning of the snow is still more than a day away, it’s too early to put final numbers on this storm. However, a good starting point is a widespread 6″ or more of new snow Sunday night through Tuesday!
Here’s a forecast map showing the likelihood of up to 8″ of snow from NOAA. This is not my forecast, just another product to look at it. The darker blues indicate where the heaviest snows will likely fall and that’s very closer to the Quad Cities.
I’ll watch this upcoming snow event for the rest of the weekend and give you an update Sunday.
And, what’s even more exciting, I get to bring this forecast to you on television Monday morning bright and early at 5 a.m. when I start as the morning meteorologist on “CBS4 This Morning”.
P.S. You want some good news if you don’t like snow? Warmer temperatures are expected next weekend with 30s and 40s!
