Snowfall Forecast Updated

Update:
Morning and midday computer models have all shifted this system further north into the area. We are still forecasting a 1-3 inch event but a 4 or even 5 inch report is now possible. The best chance of heavier precipitation will be in a band from East Central Iowa through Jo Daviess, Stephenson, and Green County, into Rock County...just a hair north of the city of Rockford.

Afternoon Synopsis:
Snow will intensify after the evening commute with a round of heavy snow expected a few hours either side of midnight. That's when the roadways will be most hazardous. (Actually perfect time for the snow to fall since very few of us will need to travel during the late-night hours.)

Snow will taper off to flurries by daybreak. Roadways will be slushy in the metro with some snowpacked roads expected NW of the city.

More to come. -ERIC

Do you think Belvidere will mostly get 1 or 3 inches of snow?

What time should the snow get around the rockford area?

Eric Sorensen said...

Honestly, I think most of this is going to be melting as it's falling. Still sticking (no pun intended) to 1-3 inches for the Rockford metro with an isolated 3-4 inch report north and west.

I'd appreciate any reports that you have. If you are near a computer simply give them to me at esorensen@wrex.com. During busy times I may not have the weather center phone turned on.

Thanks in advance!!!

The weather Channel said that we will only get up to 1 inch for the entire area.

It depends on when you measure it actually. When most people wake up on Thanksgiving morning there will only be an inch or two on the ground. During the night there could be 2-3 inches on the ground. The melting from the ground up will take its toll on the snowpack during the whole event. -ERIC

What does the Weather Channel know? ;-)

Question about measuring snowfall when it is melting rapidly:

Do you just measure water content and then guess how much snow must have fallen to produce that much water? Or...

Inquiring minds want to know.

Eric Sorensen said...

No, just measure the depth of the snow. With ground temps around 45 it's going to be really hard to measure the 4"+ since it will likely only last for an hour or two after its fallen.

We'll wake up to an inch or two by morning due to the melting. Great question! -ERIC
