.DISCUSSION.../Issued 1010 PM CDT Fri Apr 20 2018/
Have made a few changes to the forecast including adjustments to
the cloud cover overnight and surface winds. No other significant
changes made to the forecast. Upper ridge axis has shifted East of
the Four State Region and the large surface high pressure system
center has shifted into the Great Lakes Region. The surface winds
will be increasing slowly from light and variable or light East to
Southeast 5-10 MPH with slightly higher speeds into parts of East
and Northeast Texas around the back side of the surface high. The
flow aloft will continue to become Southwest as the upper closed
low just East of the Four Corners Region advances to the East. An
associated surface low will be moving into West Texas with a warm
front reaching to the Southeast into the Western Gulf of Mexico As
the surface low winds up the pressure gradient will increase the
wind speeds across East and Northeast Texas on Saturday with
moisture increasing in the lower levels resulting in increasing
low level cloud cover to go along with the higher level cloud
cover. Showers and thunderstorms will be increasing from West to
East over the forecast area during the day Saturday. /06/
