.DISCUSSION...
Local terrain effects are once again proving to be a major
forecast hurdle with regards to temperatures tonight, especially
across Southeast Oklahoma and Southwest Arkansas. At 03z, the
temperature in Idabel was 50 degrees F, but Broken Bow, De Queen,
and Mt. Herman have already fallen into the mid 30s. The low 
temperature forecast for tonight was lowered by several degrees 
across the northern half of McCurtain County and adjacent portions
of extreme Southwest Arkansas.

Temperatures have also fallen rather quickly at Lufkin despite 
quite a bit of cirrus clouds across Deep East Texas. Forecast 
temperatures were also lowered by a few degrees across our far 
southwest zones in Deep East Texas. However, the combination of 
clouds and dewpoints still in the mid 30s should limit of how much
cooling occurs.
