Weather Underground Forecast for Monday, February 13, 2012.

The trough of low pressure that brought unsettled weather to the West on Sunday will advance into the Plains on Monday with more mixed precipitation. The trough will support a low and associated warm front moving eastward into the Southern Plains. As the system progresses, rain showers with periods of heavy rain and isolated thunderstorms will spread from parts of central/eastern Texas into western Louisiana, mixed precipitation will develop in parts of Oklahoma and Arkansas, and snow will blanket parts of the Central Plains, Mid-Mississippi Valley, and parts of the western Ohio Valley. Areas from eastern Texas through Arkansas should expect the heaviest precipitation totals. Heightened winter weather conditions will allow Winter Weather Advisories and a few Winter Storm Warnings to remain in effect through the day. Elsewhere east of the Continental Divide, lake-effect snow showers will continue along parts of the Lower Great Lakes Snowbelt.

In the West, a Pacific cold front pushing across the Pacific Northwest will drop southward across northern California, bringing coastal and valley rain and significant snowfall to the Sierra Nevadas.

Winter Weather Advisory
Mobile & Email Alerts Statement as of 3:02 PM CST on February 12, 2012

... Winter Weather Advisory in effect from 9 am Monday to midnight
CST Monday night...

The National Weather Service in St Louis has issued a Winter
Weather Advisory for snow... which is in effect from 9 am Monday
to midnight CST Monday night.

* Timing... snow will begin during the mid-morning hours and
persist through much of the evening on Monday. The heaviest
snowfall is expected to occur during the late afternoon and
early evening hours.

* Accumulations... snowfall accumulations of 2 to 4 inches are
anticipated.

* Winds... southerly winds at 10 to 15 mph with gusts to around 20 mph.

* Impacts... the heaviest snowfall is expected to occur during the
afternoon and evening commute resulting in hazardous driving
conditions.

Precautionary/preparedness actions...

A Winter Weather Advisory is issued for a variety of winter
weather conditions... such as snow... blowing snow... sleet... or
freezing drizzle and rain. It only takes a small amount of wintry
precipitation to make roads... bridges... sidewalks... and parking
lots icy and dangerous. It is often difficult to tell when ice
begins to form... so do not be caught off guard.
