.PREV DISCUSSION... /issued 944 PM CDT Wed Apr 26 2017/

DISCUSSION...
The upper level trough of low pressure axis has shifted East of
the Four State Region and the associated surface cold front
has moved out of the forecast area. Have dropped the rain chances
for the rest of tonight for most all the region and only a small
sliver of rain will occur over parts of lower Northwest Louisiana.
Have dropped the lake wind advisory due to the pressure gradient
relaxing in wake of the cold front. Winds may briefly gust but
the criteria for a lake wind advisory will not be met. Have
updated the forecast to make changes to the temperatures and
dew points along with the winds and wind gusts. High pressure
building into the region will make for a cool night over the
Four State Region. Ridging aloft and on the surface will quickly
spread over the forecast area as a progressive pattern will
return rain chances for the late half of the weekend into the
weekend. Surface winds will quickly return to the South
during the day Thursday. With a nearly zonal flow aloft our
next rain chance returns by Friday. /06/
