|12Z (6 AM) 1/1/13 Tuesday NAM 850 mb dewpoints (deg. C), winds (knots), and heights. Notice the high pressure in the Atlantic east of Florida pumping in Gulf moisture across the gulf coastal states.|
For Tuesday, there are two surface features coming into play. There is a weakening cold front from the NW crossing our area, and there is also a weak surface low pressure system that will stay along the Louisiana gulf coast. This gulf low will help to pump additional moisture into the southeast and north into our area, where the cold front will act as the lifting mechanism. The timing of the front will be around noon. Expect slight warm air advection associated with the return flow Monday afternoon into Tuesday morning. The freezing line will be slightly to our north, but with the presence of warm air advection, any precipitation should fall as rain along the frontal boundary.
|NCEP GFS mean sea-level pressure, 6 hour precipitation (inches), 1000-500mb thickness at noon Tuesday 1/1/13.|
