MODERATE SNOW MONDAY EVENING

A quick moving storm system will lead to a concentrated area of snow along the highway 20 corridors tonight into the early rush hour on Tuesday. South of highway 20 to the highway 30 corridors, sleet, freezing rain and snow will affect this area making for a messy commute Tuesday morning. A winter weather advisory has been issued from 6pm this evening to 9am Tuesday.

Light rain is expected to develop late this afternoon near the highway 20 corridor. The intensity of the precipitation is expected to increase quickly this evening with any rain changing to snow across the advisory area by mid evening. Snow will then persist overnight and end around daybreak on Tuesday. Heaviest snowfall rates will occur late this evening into the early morning hours on Tuesday.

Snowfall accumulations of 3 to 4 inches in most locations will be possible, with isolated 5 inch amounts. Light ice accumulations up to 0.1″ will also be possible. Winds will be north to northeast overnight at 15 to 20-mph with higher gusts. This will produce some blowing snow and along with the falling snow, will reduce visibilities to below one half mile at times.

Roads will become completely snow-covered and slick. Reduced visibilities due to falling and blowing snow will also make travel difficult.

A winter weather advisory for snow means that periods of snow will cause primarily travel difficulties. Be prepared for snow covered roads and limited visibilities, and use caution while driving.
