.PREV DISCUSSION... /issued 909 PM CDT Thu Mar 23 2017/

DISCUSSION...
Have updated the forecast to continue the lake wind advisory for
parts of East and Northeast Texas through 4 AM CDT due to the
pressure gradient remaining tight between surface low pressure
over the Southern Rockies and parts of West Texas and surface high
pressure located along the coast of the Carolinas. The winds will
drop off after midnight tonight and toward 4 AM, but expected to
increase during the early to mid morning hours on Friday with the
approach of the surface low pressure system across the Plains.This
movement of the surface low will tighten the pressure gradient
and allow the winds to be strong and gusty until a cold front
passes across the Four State Region late Friday night and early on
Saturday.
