BLOOMINGTON — A winter weather advisory is in effect for most of Central Illinois until noon tomorrow in the wake of a winter storm that could result in 4 to 6 inches of snow for McLean County.
Forecasters from the National Weather Service in Lincoln say snow is expected to spread into areas south of Interstate 74 by late afternoon then head toward areas north of Interstate 74. The heaviest accumulations are expected between 5 p.m. and midnight. After midnight, the snow may mix with or change to freezing drizzle.
The weather service initially expected McLean County to receive between 3 and 5 inches of snow but revised that total to between 4 and 6 inches late this afternoon. Higher totals are expected to the west and northwest.
Winds could also be a factor. Blowing out of the east at 15 to 20 miles per hour, we are likely to see gusts near 30 miles her hour which could create areas of blowing and drifting snow. Wind chill factors this afternoon will be between 2 and 12 degrees.
Once the snow arrives, forecasters predict conditions will deteriorate rapidly, making travel hazardous.
Bloomington and Normal have issued parking bans. The Bloomington parking ban is effective at 2 a.m. Friday morning and will remain into effect until further notice. Normal's ban will begin at midnight and remain in effect until 5 p.m. Friday or until all streets have be plowed from curb to curb. Normal police may ticket vechiles parded on the street.
Once the system clears, we can expect some occasional snow or freezing drizzle before noon on Friday, with a high of around 35 degrees. Friday night’s low will be around 21 degrees.
On Saturday, we will have partly sunny skies and a high near 31 degrees. Sunday looks to be mostly sunny with a high near 37 degrees.
A chance of rain or snow return to the forecast for Monday and Tuesday.
