Jan 19 Short
Forecast updated - 19 Jan 2011
For Thursday the local area is going to be seeing a good amount of precipitation. All of the model are in agreement for the amount of liquid precip for the area although the gfs model does give a more widespread forecast for snow. The majority of the area will be seeing snow, and to the south a rain/snow mix then a shift to rain as we head into the southern states. A similar situation will be occuring out to the west in the Washington state, with the portions farther east seeing snow then a rain/snow mix to rain as you head west.
The second focus will be on the temperatures. Significant cool downs are expected. At 850 mb Arctic air will be coming into the states cooling down much of the north and central states. So, plenty of cold air advection. The Washington DC area will also be seeing a large cooldown as they wait for this precipitation event to hit their area early Friday morning.
