January 13 Long Range Forecast

Forecast updated 1:30pm EST - 13 Jan 2011

Martin Luther King Day brings the next significant chance for precipitation.

This is expected to occur Monday afternoon over parts of the Gulf states and the Ohio river

valley. This system is primarily being fueled by temperature advection, while the

northwestern part of the United States has larger amounts of vorticity advection

acting as the driver of precipitation.

The map below depicts the forecast of Monday at 1800 or 1 pm in the afternoon. Parts

of Kentucky and southern Indiana look to have heavier amounts of precipitation. The freezing

line is forecasted to push through the lower Great Lakes area, so expect for snowy conditions in

northern Indiana and extending west into the Dakotas.
