A strong winter storm system is forecast to produce snow and potent winds to the area late tonight into Thursday. A wintry mix of precipitation is anticipated to quickly transition to snow late tonight and continue to transition Thursday morning. The combination of accumulating snowfall and the strong winds may produce poor visibilities and difficult travel conditions.
A winter storm warning has been issued from 3 am to 6 pm Thursday, as heavy mixed precipitation is expected. The mixed precipitation will change to all snow by Thursday morning. Plan on very difficult travel conditions, including during the morning commute on Thursday as quickly dropping temperatures produce rapid freezing on area roads and highways.
In addition, significant reductions in visibility are expected from falling and blowing snow. Winds gusting as high as 40 mph will cause widespread blowing and drifting snow with visibility reduction below one half mile common on Thursday morning. Total snow accumulations of 3 to 6 inches and ice accumulations of a light glaze are expected within the winter storm warning.
A winter weather advisory has also been issued. This is where total snow accumulations 1 to 3 inches is expected with localized amounts up to 4 inches, especially west of Interstate 35. A light glaze of ice is also expected before the transition to all snow.
