The wicked winter storm will continue to rage tonight. Do not be fooled by lack of wind so far. The wind will increase this evening, and travel may turn very dangerous.

Here are the main points of this update:

The new computer model runs are in. The same computer model that I showed you in my morning update now still forecasts about the same amount of additional snow. In other words, the snowfall amounts will be higher, as the storm is a touch slower and bringing longer lasting snow.

The wind is now going to start to increase and change the pretty snow into a blizzard. Wind gusts will increase to over 30 miles per hour starting between 7 p.m. and 10 p.m.

If you don't have to drive for an emergency tonight, stay home. The weather is going to change dramatically.

Ok, I think I shouted in "all caps" enough that you got my point. Now let's check out some specifics.

Some areas will now get over 16 inches of total snow

The top graphic shows you additional snow yet to fall from 4 p.m. today through noon Monday. You will notice that this graphic looks very similar to my morning update. That means this storm will produce even more snow than earlier thought.

Another seven to nine inches is still going to fall in Detroit, Ann Arbor, Jackson, Flint, and Lansing.

Another five to seven inches of snow is still to come in Saginaw, Bay City, Midland, Kalamazoo, and Grand Rapids.

Muskegon should get another three to five inches by noon Monday.

The heaviest snow is now in most of southern Lower Michigan, and will last until at least midnight. There could be very heavy snow around the Detroit and Ann Arbor areas this evening, with even the possibility of thunder and lightning.

Reports of snow so far are between six and 10 inches from Kalamazoo and Jackson to Lansing, Flint, Saginaw, and the Thumb. In those areas total snowfall now looks like it could top 17 inches in spots.

Detroit and Ann Arbor have reported three to five inches as of 4 p.m. and it is piling up fast. Another seven to nine quick inches of snow tonight will put Detroit and Ann Arbor between 10 and 14 inches for a storm total.

Grand Rapids is reporting five to seven inches so far. Add on another five to seven inches tonight, and you will also shovel 10 to 14 inches in the Grand Rapids area.

The Muskegon area has had three to five inches and should get another three to five, putting the total there at six to ten inches.

It's a lot of snow.

But the wind will become a major factor, followed by dangerous cold.

I will address the cold in another post. For now I want to give you a feel for what I think will be a dangerous wind.

Here is an hour by hour forecast of steady wind speed in purple and wind gusts in blue for Detroit/Ann Arbor and Saginaw/Bay City. Notice the increase in winds this evening to gusts to 30 to 37 miles per hour.

Wind will become the most dangerous factor

The storm center is still strengthening. The storm center is in southern Indiana right now and will strengthen as it moves to around Cleveland by midnight. A strengthening low pressure system causes winds to increase.

The wind forecast graph I've made shows two locations - Detroit/Ann Arbor and Saginaw/Bay City. I'll work on a more indepth wind forecast soon, but I wanted to show you what is going to happen.

The purple line is the steady wind. Notice the steady wind in Detroit and Ann Arbor is going to increase from nine miles per hour at 7 p.m. to 21 mph by 10 p.m. In the Saginaw/Bay City area the steady wind will increase sooner and be around 21 miles per hour by 7 p.m.

The blue line is probably the more important line. It is the wind gust forecast. Look at the big increase in wind gusts in the Detroit/Ann Arbor areas between 10 p.m and 1 a.m. Winds could gust over 35 mph, producing blizzard conditions. Saginaw and Bay City won't be any better. Winds will gust around 35 mph, if not a little more all night.

It is a pretty simple forecast to understand for tonight. Heavy snow and dangerous blowing snow.

I will continue to give you updates through the evening.
