Update On Winter Storm, Starting Tomorrow NightArchived Message

The forecast models have shifted slightly over the last 24 hours, and that's not a good thing, and here's why:
The start of the really heavy snow has been shifted about six hours farther into the future in Tuesday.
WHAT THIS MEANS:
We're going to receive a significant ice accumulation as a result, possibly upwards of an inch starting Monday night and ending Tuesday EVENING, when the Arctic front spills cold air over our region to produce an all-snow event.
The incoming winter storm over the Granite City area, therefore, will be a major ICE event with a bunch of snow afterward, probably in the 5" to 7" range. Only a hundred miles to the north, forecast models are predicting 13 to 15 inches of snow.
But the danger is ICE with this storm for Granite City, as the models indicate. Tuesday is a very, VERY good day to stay home and hunkered down as travel will be unbelievably treacherous throughout the evening.
When the cold Arctic winds start blasting through here Tuesday night and into all day Wednesday (With 50 MPH gusts expected), you can expect sporadic power outages from tree limbs falling onto power lines.
I'd lay good money on Granite City schools being canceled maybe on Tuesday, and for sure on Wednesday.
So: North of Granite City...expect to be buried under a foot of snow.
Granite City proper: Ice, ice, baby. Take care when you step outside starting Tuesday morning.
