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.

Nowcast as of 10:12 PM CST on February 12, 2012
Through the overnight hours...light rain will continue to move northeast at 25 mph across south central Texas and The Hill Country. New rainfall amounts through 1 am will generally average less than one tenth of an inch...but isolated higher totals near one quarter of an inch are possible. Even though frozen precipitation is not expected overnight...roads are still slippery from the mix of rain and wintery precipitation earlier today. Drivers should be extra cautious since slick patches of roadway are especially difficult to see in the dark.
