National Weather Service Shreveport LA 1002 PM CST Wed Dec 13 2017 .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. Updated text products have been sent. CNNational Ag. Weather Outlook, International Ag.
