Wintry Round 2

Snowfall Totals 11PM Friday:

Friday PM Update:
A WINTER STORM WARNING has now been issued for much of Southern Illinois and SE Missouri with Winter Weather Advisories continuing elsewhere. Here is the latest map and forecast accumulations for the Local 6 area. Road will become slushy and slick by Saturday morning. Motorists are encouraged to use extra caution and don't forget to carry along a winter weather kit for your vehicle.

Friday Afternoon Update:
Snowfall totals have been adjusted a bit to reflect the slightly stronger storm system. Just like the last storm, highest totals are expected north of the Ohio River back into SE Missouri. Lighter accumulations are expected and winds will not become so hazardous. A WINTER WEATHER ADVISORY is in effect for those in the second map below.

Thursday Night Update: Sitting here sifting through the newest model data and with snow still on the ground, colder surface temperatures may lead to some light icing on area roads first thing Friday morning. Light rain mixed with freezing drizzle looks to be a real possibility, more likely in the areas I have outlined on the map below:

This wintry mix should turn to all rain by late morning to noon. Colder air will then be drawn down from the north and change the rain over to sleet and snow by evening and overnight Friday into Saturday. Light accumulations are expects mainly over the areas with snow still on the ground. Here is latest snow accumulation map, ending Saturday morning.

This winter event will be way less significant compared to the winter storm that just swept through Christmas night. With that being said, even just a small amount of freezing drizzle can create black ice for morning commuters. Just take it slow and give yourself a little extra time to get to work to be on the safe side.
