.PREV DISCUSSION... /issued 259 PM CST Fri Nov 16 2018/

DISCUSSION...High pressure is sliding east along the South
Louisiana coast this afternoon, while a dry west to northwest flow
remains in place aloft around the base of a trough.

This weekend temperatures and moisture will gradually increase as
the ridge continues toward the Atlantic allowing the flow to
become more southerly. Aloft a weakening short wave will drop
southeast out of the Pacific Northwest toward the plains
increasing cloud cover and possibly working a few isolated showers
into East Texas late Sunday afternoon.

Rain chances are expected to increase Monday and Tuesday as weak
low pressure develops along the Texas Coast and the weakening
short wave moves in, however higher chances are expected Wednesday
into early Thursday as a second, stronger system moves across the
region.

Models vary a bit on the strength and track of the surface low
along the coast. This will have most impact on areas south of
Interstate 10, with areas to the north most likely remaining in
the stratiform rain set-up.

Improving conditions are expected during Thanksgiving.

MARINE...High pressure is departing the area with the flow
becoming onshore. A light to moderate onshore flow is expected
into Sunday Morning, however low pressure will develop along the
coast of South Texas which will increase winds during Sunday.
Moderate east winds will remain in place Monday and Tuesday along
with showers. An increase in winds can be expected as low pressure
moves along the coast during the middle of the week.
