20 January Current

Currently, a low pressure system located in Tennessee is bringing a large amount of snow to portions
of the Ohio River Valley.  This system is being primarily driven by the positive vorticity advection in the
southern parts of Illinois and Indiana out in front of the vort. max.  This max is located in the central portions of these
states.  This system will soon move out of the area and to the northeast due to strong upper levels winds
as shown in the 250 mb heights, isotachs, and wind map at the bottom of the page.  Associated with the
system, there has currently been precipitation amounts of 0.20 inches recorded by the National Weather Service
throughout mid to southern Indiana.  The maps below made of use of models produced by Metar and the GFS211.
