Additional Snow through AM Tuesday
Submitted by Sharon Ray on Mon Feb 8, 2010 4:22pm
The final band of snow with this storm system is moving through mid-Missouri now. Light snow is reported across much of the region although it has let up in a few spots. As the arctic front approaches, snow will increase through mid evening before pushing east. Steady light snow, moderate at times will continue until 9 pm before letting up and ending after midnight.
There is a narrow band of heavy snow which will produce a period of 20 to 30 minutes of heavy snowfall as it moves through from 5-6 pm near highway 65, 7-8pm near highway 63 and 9-10 from highway 54 eastward. Snow will become light and end as temperatures rapidly fall overnight.
Melting is cutting down on our snow totals for afternoon and evening. Below are additional totals from 4 pm through Tuesday morning.
UPDATED Timing of Heaviest Snow for PM Commute
Submitted by Jeff Huffman on Mon Feb 8, 2010 10:39am
I've been looking over the new Futuretrack data this morning, comparing it to radar and satellite representations of this storm, and pondering whether or not to make any changes to our going forecast. I've decided to tweak a few things, but overall I see no reason to deviate much from what we have been forecasting for several days now. A general 4 to 6 inch snowfall will still likely occur - on average - across most of Mid-Missouri by the time the storm is finished Tuesday afternoon. However, it now appears that about an inch of that will hold off until Tuesday with some wrap around snow showers. Furthermore, I'm seeing a slight increase in the forward speed of the arctic front across the northern plains. This should help to spread the heavier snow into Mid-Missouri more quickly and result in a greater impact for the evening drive across most areas. Some banding of the snow will be rather intense, with snowfall rates close to 1 inch per hour possible for a brief time early this evening.
EVENING COMMUTE: The chart below represents an approximate starting and ending time of snow for this second wave, along with the times when the snow should be at its heaviest. A slick and potentially hazardous commute is expected at this point.

UPDATED SNOW TRACKER (STORM TOTALS):
This has not changed much, but I do believe storm totals will be close to 4 inches in Columbia and Jefferson City by Tuesday afternoon, with a stripe of 5 to 6 inch amounts through portions of Pettis, Cooper, Howard, Randolph, and Macon counties.

Winter Weather Advisory
Submitted by Sharon Ray on Sun Feb 7, 2010 7:36pm (BACK TO TOP)
The National Weather Service has issued a Winter Weather Advisory which replaces the Winter Storm Watch which was issued earlier. We are still expecting up to 6 inches of snow in mid-Missouri with local amounts of 7" possible but since most areas will get just under 6 inches, an advisory was issued.
Timing Snow, Arctic Air & Wind
Submitted by Sharon Ray on Sun Feb 7, 2010 7:31pm (BACK TO TOP)
Below is the latest Futuretrack showing snow moving into mid-Missouri from late evening through Monday night. Here are some details on the timing of the snow.
- Light snow through the morning commute will melt on most roads and be slushy on less treated or untraveled roadways.
- Snow will become lighter from mid-morning through early afternoon.
- Snowfall rates will increase from mid-afternoon through evening with a band of heavy snow reducing visibilities.
- Roads will be snow covered for the evening commute with slow travel expected.
- Snow will taper off during the late evening from west to east as much colder air moves in.
Timing varies depending on location. To see how your hometown will be affected, check the Futuretrack movie below.
Latest Snow Tracker: Sunday night- Tuesday
Submitted by Sharon Ray on Sun Feb 7, 2010 4:32pm (BACK TO TOP)
Light snow will develop late this evening, increasing after midnight. Initially the snow will melt on roadways but by daybreak it will stick, mainly on untreated and less traveled roads. By the morning commute, 1 to 2 inches of snow will accumulate on grassy surfaces with a steady, light snow falling across all of mid-Missouri.
Periods of light snow will continue through mid-morning with bands of heavy snow increasing in the late afternoon and early evening, tapering off from late evening and overnight. Expect a slow evening commute with snow covered roads and snow still falling, and reduced visibilities in pockets of heavy snow. Total snow accumulations of 4 to 6 inches are expected through mid-Missouri.
Midday Discussion & Timing
Submitted by Mike Rawlins on Sun Feb 7, 2010 12:48pm (BACK TO TOP)
After reviewing the late morning model runs, I don't see a need to alter the current forecast by much. If anything, the snow will likely overspread mid-Missouri slightly slower than previous models were showing. However, this does not mean there will be less snow overnight into Monday morning than previously forecast. The previous winter storm discussion talks about 1-2" of snow by Monday morning's commute and the possibility of needing to up that by an inch or two. Right now, I see no indication of there being widespread accumulation of more than 2" by morning, but some locally higher amounts are always possible. In any case, snow will start up this evening, as shown by this Futuretrack animation I've included below.
At this time, I won't make any major forecast changes for our region, as the going forecast looks accurate, but expect some minor tweaks to overall storm totals by this evening. Also, expect Winter Storm Warnings and Winter Weather Advisories to be issued within the next 6 hours for much of mid-Missouri.
WINTER STORM UPDATE: Sunday Night through Monday
Submitted by Sharon Ray on Sun Feb 7, 2010 12:45pm (BACK TO TOP)
A Winter Storm Watch continues for all of mid-Missouri through Monday evening as much of the area will pick up 4 to 6 inches of snow with locally higher amounts possible by Tuesday morning. Light snow will move into western Missouri late Sunday evening, spreading east after midnight into mid-Missouri. Snow will pick up toward morning with moderate snow at times. As temperatures drop to 30 degrees by morning, snow will start sticking to roadways by the morning commute with 1-2" possible by 6 a.m. on grassy surfaces.
Periods of light snow will continue through the day, increasing from late afternoon through the evening, tapering off overnight. Snow on roadways is likely for the Monday evening commute and slow travel should be expected.Northwesterly winds will increase late Monday night to 15 mph, gusting to 30 mph Tuesday with some blowing and drifting snow. Bitter cold air will grip the area Tuesday with single digit wind chills with afternoon air temperatures in the teens.
We'll continue to have updates Sunday evening on the development of the snow with live tracking as the snow moves into the region. Be sure to check back to the Stormtrack Insider and watch ABC17 News on Fox 22 Sunday at 9 pm and ABC17 News at 10.
