You’ve heard the expression, stick with your original plan.
That’s what I should have done with the snow today and tomorrow. As you recall (and, if not, I’ll remind you because you’ve heard all kinds of numbers and it can get confusing), all Sunday through most of Monday, I was calling for 3-5″ of snow for the Quad Cities and 5-7″ southeast of the metro area. I lowered those projections by just two inches last evening when other meteorologists were giving up on the storm and calling for just a couple of inches of snow.
Boy, how things change! The late Monday night computer model runs started generating more snow and that trend continues into Tuesday morning. With that being said, the “Winter Weather Advisory” for the Quad Cities is now a “Winter Storm Warning” for today through early Wednesday morning. That’s indicated on this map by pink and the “Winter Weather Advisory”, where lesser amounts of snow are expected is in purple.
As of this blog entry, around 7 a.m. Tuesday, light snow is already falling across parts of southeastern Iowa and west-central Illinois. This will spread northward to the Quad Cities by mid-morning or by noon.
The snow will become heavy this morning in the south and in the afternoon in the metro area.
Our storm is located over Missouri early this morning and here are the GFS forecast maps for noon Tuesday, 6 p.m. Tuesday, and then six hours later at midnight. The heaviest snows are indicated by darker greens and blues.
While the heaviest snow will fall today and start diminishing late tonight, we’re still going to see light snow Wednesday that could accumulate another inch or so.
Since I’ll be at work today and this is a personal blog and forecast, I will not be able to give you any more updates until this evening. However, that’s not really an issue since this is my final forecast for this storm. Yes, Meredith, that’s my final answer. 🙂
Here are my snow totals I expect to fall today through Wednesday evening.
Can many of you say “SNOW DAY”!!!!!!!!!!!!!
Kidding aside, this is going to be a dangerous winter storm. In addition to the heavy snow falling today and this afternoon and evening, we’ll see blustery conditions with winds of 20-40 miles-per-hour giving us near white out conditions, at times.
This is especially bad in open areas where there’s nothing to stop the wind-blown snow. Also, this is a problem for high-profile vehicles on the Interstate (i.e. semis).
I know many of you are wishing spring arrives soon.
